Vaccinium spp.
Blueberries are widespread with residence gardeners as a result of, let’s face it, they’re scrumptious. However whereas the berries get a lot of the consideration, the bushes are stunning vegetation in their very own proper.
Blueberry vegetation bloom throughout mid- to late spring – sometimes in Could or June, relying on the species and cultivar – with showy white, pink, or purple flowers.
Because the blossoms give method to fruit in the summertime, sometimes July and August, darkish inexperienced leaves with gentle undersides present distinction in opposition to the ripening gentle to darkish blue berries.
Within the fall, the foliage turns crimson, orange, purple, yellow, or a combination of those colours.

There are 5 frequent sorts of blueberry vegetation on the market, starting with the most well-liked in industrial cultivation, the northern highbush (Vaccinium corymbosum).
Subsequent now we have the southern highbush, which is a hybrid of V. corymbosum and a local species from Florida referred to as the evergreen blueberry, V. darrowii.
Then there’s the lowbush species (V. angustifolium), which grows low to the bottom, staying below two toes tall. It’s native throughout the US and Canada and the sort that individuals typically forage within the wild.
And there’s additionally the rabbiteye species, V. virgatum. These develop native throughout the southern US and may attain as much as 20 toes tall.
Lastly, there’s the half-high, which is a hybrid of lowbush and highbush blueberries.
Cultivars of every species have been bred to provide fruit that matures at totally different occasions – early, midseason, or late.
There’s quite a lot of attention-grabbing and helpful details about rising blueberries to cowl, so let’s leap proper in! Right here’s what we’ll go over within the coming sections:
What Units the Totally different Frequent Blueberry Sorts Aside?
Highbush blueberries (V. corymbosum) are deciduous woody shrubs that may attain as much as eight toes tall at maturity.
![A close up vertical image of a northern highbush blueberry shrub growing in the garden with trees in soft focus in the background.](https://gardenerspath.com/wp-content/uploads/2021/03/Northern-Highbush-Blueberry-Bush.jpg)
In distinction, as you would possibly anticipate from their identify, lowbush berries (V. angustifolium) are considerably shorter deciduous woody shrubs.
Generally referred to as wild blueberries, these solely attain heights of about two toes tall.
![A close up horizontal image of a wild Vaccinium shrub growing in a rocky soil pictured in bright sunshine on a blue sky background.](https://gardenerspath.com/wp-content/uploads/2021/03/Blueberries-Growing-Wild.jpg)
Moreover dimension, one other approach wherein the accessible varieties differ pertains to gardening area. Some highbush and rabbiteye vegetation can develop in hotter climates, whereas lowbush varieties can tolerate cooler climates. Half-high blueberries sit someplace within the center.
Highbush varieties develop finest in USDA Hardiness Zones 4 to eight, whereas lowbush varieties develop comfortably in Zones 2 to 7.
Half-high bushes develop finest in Zones 3 to 7. It’s potential, nevertheless, to seek out particular cultivars that may develop outdoors of those ranges.
Why the distinction? It isn’t simply that highbush vegetation can’t deal with prolonged durations of freezing temperatures, however since they’re so tall, stems can break and they are often crushed below heavy snow.
Lowbush vegetation, alternatively, don’t thoughts a thick blanket of snow.
These species are additional damaged down into northern and southern varieties, with narrower ranges of appropriate local weather.
For instance, northern highbush and lowbush blueberries want about 800 to 1,000 chilling hours, whereas southern highbush vegetation want about 150 to 800 hours, relying on the cultivar.
Half-high bushes, as you would possibly anticipate, want one thing within the center, often round 800 hours.
What’s that, you ask?
“Chill hours” refers back to the variety of hours that temperatures have to be someplace between 32 and 45°F within the winter to ensure that the vegetation to provide flowers and fruit the next spring and summer time.
A little bit of an outlier, rabbiteye blueberries (V. virgatum) stand out as a result of they ripen a couple of month later than lowbush or highbush varieties, and the berries are smaller and sweeter, with a more durable pores and skin.
The immature berries are creamy white or pink in shade with a brilliant crimson or pink calyx, giving the fruit the looks of an albino rabbit’s eye.
![A close up horizontal image of rabbit eye blueberries ripening on the shrub pictured on a soft focus background.](https://gardenerspath.com/wp-content/uploads/2021/03/Rabbit-Eye-Blueberries-Growing-in-the-Garden.jpg)
Rabbiteye bushes can develop as much as 20 toes tall and are a bit extra tolerant of dry situations or drought than different varieties. They aren’t in a position to tolerate quite a lot of water, like different kinds of blueberries can.
Rabbiteyes develop finest in Zones 7 to 9 and want between 300 to 700 chilling hours, relying on the cultivar.
Cultivation and Historical past
Berries within the Vaccinium genus develop wild internationally.
As an illustration, in northern continental Europe, Eire, the British Isles, Iceland, and northern Asia, you’ll find the native European blueberry (V. myrtillus), often known as the forest blueberry or bilberry.
![A close up horizontal image of ripe homegrown blueberries ready to harvest.](https://gardenerspath.com/wp-content/uploads/2021/03/Ripe-Homegrown-Blueberries-Growing-in-the-Garden.jpg)
In South America, you’ll find the mortiño (V. floribundum) and the Jamaican bilberry (V. meridionale).
However once we speak concerning the blueberries you’re more likely to discover on the retailer, we’re often speaking concerning the vegetation native to North America.
Initially, all blueberries rising in North America had been uncultivated lowbush or rabbiteye vegetation, together with a number of different species like V. alaskaense, or the Alaskan blueberry, and V. ovalifolium, or the oval-leaf blueberry).
Scientists assume the blueberry was one of many first fruit vegetation on the continent to be utilized by people after the final ice age.
It was due to the indigenous populations residing in what turned referred to as the US that European settlers discovered about this magnificent fruit.
Native People ate the berries recent after they had been in season, cooked them into stews and meats, baked with them, and dried them to be eaten throughout the winter. In addition they used them medicinally.
Folks continued to reap, eat, and protect wild blueberries solely, till Elizabeth Coleman White and Frederick V. Coville got here alongside.
White labored on her dad and mom’ cranberry farm within the late 1800s. On the time, growers didn’t assume the wild blueberry may very well be cultivated, however White believed she might make it occur.
She reached out to Coville, a botanist with the USDA who was additionally learning wild blueberries, and the pair labored collectively to create the primary domesticated highbush blueberry.
Lately, northern highbush are the commonest commercially grown blueberry in North America and the berries that you simply see on the grocery retailer in these plastic clamshells or berry baskets are often highbush varieties.
![A close up horizontal image of ripe blueberries in plastic containers at a grocery store.](https://gardenerspath.com/wp-content/uploads/2021/03/Blueberries-in-Plastic-Containers-at-the-Store.jpg)
The southern highbush has solely been cultivated for the previous six many years or so. It’s a hybrid of northern highbush and rabbiteye or evergreen varieties.
However that doesn’t imply the lowbush blueberry isn’t round anymore. It’s an necessary crop within the northeastern United States and Canada, the place it’s cultivated or harvested from managed wild stands.
These berries are often offered both canned or frozen as a result of they don’t retailer or ship nicely, although you’ll find them recent regionally throughout the rising season.
Rabbiteyes are grown commercially within the southeastern United States, and in case you’re fortunate sufficient to stay within the area, you’ll find the fruits recent at markets and grocery shops throughout the summer time.
Whereas North American blueberry species are cultivated throughout the globe, from Australia to Siberia, a majority of the commercially grown berries offered worldwide come from the US.
Propagation
You have got a number of choices relating to propagating your vegetation.
Naked roots, cuttings, and transplants are best, however in order for you a rising journey, you may as well domesticate them by beginning seeds.
![A close up horizontal image of a Vaccinium shrub with ripe and unripe berries growing in the garden pictured on a soft focus background.](https://gardenerspath.com/wp-content/uploads/2021/03/Homegrown-Blueberries-Ripening-on-the-Shrub.jpg)
Whichever methodology you select, make sure you prep your soil nicely earlier than sticking your new vegetation within the floor. If you want to alter your soil a lot, it may be a prolonged course of.
As an illustration, if in case you have clay or sandy soil, working in some composted pine or fir sawdust repeatedly over a number of months may help create the best situations for blueberries.
From Seed
Starting with essentially the most difficult choice, you may develop blueberries from seed, however it is going to clearly take longer to provide your first harvest than it will in case you began with established vegetation.
Seeds may be bought or you may extract them from the berries. Remember that seeds from hybrid vegetation received’t develop true to the guardian.
To extract seeds, place a cup of blueberries in a blender with 4 cups of water. Run it on excessive for 15 seconds after which let the combination sit for 10 minutes.
Finally, the pulp will rise to the highest and the seeds will sink to the underside.
Pour out the pulp, add extra water to switch what you poured out, and set it apart for an additional 5 minutes. Repeat till you get clear water with blueberry seeds on the backside.
Just a few months earlier than the final frost date in your space, sprinkle your seeds over a container full of moistened peat moss.
Place a skinny layer of peat on high to cowl. Cowl the tray with a bit of plastic or a humidity dome to maintain the moisture in. Hold the seeds round 60 to 70°F.
Now comes the ready recreation. Each time I’ve achieved this I’m fairly certain my seeds are duds and I get able to toss the entire thing out, solely to see the little inexperienced seedlings stick their heads out of the peat.
That’s as a result of it may well take a month or two – or generally three! – for seeds to germinate. And I’m impatient.
As soon as seedlings are about three inches tall, take away them from the peat and put every one in a six-inch pot full of equal elements peat, sand, and potting soil.
Hold the medium moist however not moist, and put the seedlings in a spot the place they obtain about six hours of solar a day.
![A close up horizontal image of Vaccinium shrubs growing in nursery pots ready to transplant into the garden.](https://gardenerspath.com/wp-content/uploads/2021/03/Blueberry-Bushes-in-Nursery-Pots.jpg)
As soon as the hazard of frost has handed, you may put the vegetation within the floor outdoors, however make sure you harden them off for every week earlier than transplanting them to their everlasting residence.
Harden off seedlings by inserting them outdoors in a sheltered spot with oblique gentle for one hour, after which convey it again indoors. Repeat this, including an hour every day for every week, till they’ll spend the total day outdoors.
As a result of the seeds want such rigorously managed situations, direct sowing within the backyard isn’t really helpful.
By Cuttings
When you’ve got entry to an older, wholesome blueberry bush, you may take hardwood cuttings to start out new vegetation.
Within the late winter when the plant continues to be dormant, take a six-inch reducing from one-year-old wooden. You desire a reducing that’s about as thick as a pencil.
![A close up horizontal image of two hands from the right of the frame pruning a Vaccinium shrub in the winter.](https://gardenerspath.com/wp-content/uploads/2021/03/Pruning-Blueberry-Bushes-in-the-Fall.jpg)
Reduce the tip you’ll be burying at an angle to help in sinking it into the soil and to extend the floor space for water and nutrient uptake.
Bury the reducing two inches deep in a container full of equal elements sand, peat moss, and potting soil.
I like to make use of four- or six-inch containers, ideally a compostable kind like CowPots.
![A close up horizontal image of a biodegradable pot for starting seeds.](https://gardenerspath.com/wp-content/uploads/2021/03/CowPots-Biodegradable-Pot.jpg)
CowPots Biodegradable Pots
Arbico Organics sells these useful pots in packs of 12, 180, or 450 – for these critical gardeners!
Hold the potting medium moist however not moist. In about three months, your reducing ought to develop roots. You’ll know that is the case in case you give the reducing a mild tug and it resists.
As soon as the chance of frost has handed, harden off the rooted reducing as described above, after which plant it in its everlasting spot.
Dig a gap twice as huge and as deep because the container the reducing was rising in. Put the plant within the gap, spreading out the roots. Backfill with soil and pine or fir sawdust, if utilizing.
Rooted cuttings will take about two or three years greater than transplants to provide berries.
By Naked Root
Naked root vegetation are usually extra reasonably priced than transplants, however they take a bit of additional prep to propagate.
Should you can’t plant yours straight away after your order arrives otherwise you convey them residence from the nursery, put them in a cool, darkish place. You don’t need to let the roots dry out, so spray them every day with a water bottle.
If you’re able to plant, soak the roots in room temperature water for 3 to 6 hours. Take away from the water and lower away any damaged roots.
Then, unfold the roots out horizontally somewhat than down and dig a gap that could be a few inches wider and the identical depth because the roots.
These shrubs want to have their roots near the floor of the soil somewhat than down deep, so we’re making an attempt to recreate their pure rising behavior once we do that.
Place within the gap and backfill with soil that you simply dug up. Water nicely to settle the soil.
Learn extra about blueberry propagation right here.
Transplanting
Should you’re in a rush to dig into these candy berries, you should purchase one, two, or three-year-old blueberry transplants.
Most vegetation begin producing at about two years previous, so you might be digging in straight away, although your first harvest could also be small.
Transplants needs to be planted within the fall or spring, relying on the place you reside. Gardeners in hotter areas just like the Pacific Northwest or the Southeast ought to put vegetation within the floor in October, March, or April.
In cooler areas like New England, spring is finest to be able to enable the plant time to change into established earlier than winter rolls round.
If you end up able to plant, gently take away it from its container and make sure you totally loosen up the foundation ball. Unfold the roots out, not down.
If you’re achieved, the foundation system needs to be about twice as huge and half as deep because it was whereas confined to the pot it got here in.
Dig a gap barely wider than your newly spread-out root ball and about the identical depth.
You might need to work some peat or compost into the encompassing soil if the feel of your earth is totally different from the soil the transplant was rising in. This helps to enhance aeration and encourages the roots to broaden.
As an illustration, in case your potted blueberry is in a loamy potting combination, however your native soil is sort of sandy, you’ll have to amend your soil to encourage the roots to increase into your native soil.
You’ll be able to study extra about easy methods to transplant blueberries in our information.
Learn how to Develop
Blueberries are ericaceous vegetation, together with different acid-lovers like rhododendrons, azaleas, and hydrangeas. All of them like related acidic soil situations.
![A close up horizontal image of ripe blueberries growing in the garden pictured on a soft focus background.](https://gardenerspath.com/wp-content/uploads/2021/03/Growing-Blueberries-in-the-Garden.jpg)
You can too develop them close to timber that thrive in acidic soil, comparable to some pines. Simply bear in mind, there’s a typical backyard delusion on the market that pine needles make the soil acidic.
That’s not true. Don’t assume that you could plant your blueberries close to a pine tree and the soil may have the best pH.
Blueberry vegetation want acidic soil with a pH between 4.0 and 6.0, relying on the species. All blueberries want soil that’s porous, with a number of natural matter. However they don’t want a ton of further vitamins.
Check your soil a 12 months earlier than planting so you’ll have time to make amendments to regulate the pH – if you want to – earlier than placing your new blueberries within the floor.
Take note, nevertheless, that rabbiteye blueberries don’t do nicely in soil that doesn’t naturally have a pH at or beneath 5.5.
In case your soil has a better pH stage than this, both construct a raised mattress and fill it with acidic soil, or plant someplace that does have the best pH, somewhat than utilizing a soil modification like sulfur to alter the pH.
These vegetation want a good steadiness of nitrogen, potassium, and phosphorus. Which means in case your soil is poor in one in all these vitamins, you’ll want so as to add it.
As an illustration, in case your earth is low in nitrogen, you’ll need to work in one thing like blood meal so as to add nitrogen.
I really like this product from All the way down to Earth, which you should purchase in half, 5, 20, or 50-pound packages at Arbico Organics.

After conducting your soil check, amend with any mandatory fertilizer earlier than planting your new bushes, and let the granules dissolve for every week or two. Fertilizer granules that contact younger roots straight can burn them.
In case your soil isn’t naturally loamy, work in some aged fir or pine sawdust, or finely chopped bark, to enhance aeration.
You’ll be able to decrease the pH by including pelletized or granular elemental sulfur or peat moss to the soil, following the producer’s suggestions. Sulfur takes a couple of 12 months to change soil pH.
Alternately, you may as well use aluminum sulfate, or iron sulfate. These work sooner, however you want to watch out to not add an excessive amount of. It’s straightforward to overdo it with sulfates.
When you’re testing and bettering your soil earlier than you plant, you must also take away any weeds from the world. Blueberry vegetation don’t prefer to compete for vitamins, solar, or moisture.
That’s as a result of they’ve shallow root programs, with out large faucet roots to dig deep into the soil for water and meals.
You can too plant a canopy crop to assist enhance the soil and beat again weeds. Rye, buckwheat, or sudangrass (Sorghum x drummondii) all work nicely for this goal.
![A horizontal image of a garden planted with a cover crop against a blue sky background.](https://gardenerspath.com/wp-content/uploads/2021/03/Growing-a-Cover-Crop.jpg)
Think about using raised beds if you want to amend your soil to swimsuit blueberries. Whether or not the soil lacks vitamins or wants pH adjustment, or if in case you have heavy, compacted or clay soil, you would possibly need to assemble a number of raised beds to plant in.
This provides you the power to change the soil with out impacting the encompassing space.
You’ll be able to construct a wood field, or simply hill up some improved soil in case you want. When you’ve got heavy soil, you may as well work in some sand to enhance drainage.
You need to group blueberries collectively, somewhat than spreading them out round your backyard. That makes it simpler to maintain the soil pH on the proper stage, which is vital to an ample harvest. It additionally helps the vegetation pollinate one another.
Not all blueberries want a companion for pollination, however many do. This implies you want to plant cultivars collectively that bloom on the identical time.
Southern highbushes have to be planted with a cultivar that blooms on the identical time, and this can sometimes be famous within the plant description or on the rising tag from the nursery.
Rabbiteye blueberries additionally want a companion for pollination. Once more, make sure you decide cultivars that bloom at an identical time.
‘Alapaha,’ ‘Climax,’ ‘Premier,’ ‘Prince,’ ‘Savory,’ and ‘Vernon’ are all early bloomers.
‘Austin,’ ‘Brightwell,’ ‘Columbus,’ ‘Montgomery,’ ‘Powderblue,’ and ‘Tifblue’ all bloom mid-season.
‘DeSoto,’ ‘Ochlockonee,’ and ‘Onslow’ are late bloomers.
Most highbush cultivars are self-fertile, however cross-pollination will sometimes provide you with a bigger harvest and greater berries.
Whereas harvest dates can differ dramatically amongst totally different cultivars, most northern highbush vegetation bloom inside every week or so of one another. For that cause, all cultivars can be utilized for cross-pollination.
Native bees, bumblebees, and honeybees are the one pollinators of blueberries. The flowers can’t be pollinated by birds or butterflies as a result of they require “buzz pollination.” This occurs when a bee vibrates or shakes the pollen unfastened from a flower.
Massive highbush species needs to be spaced round 4 to 6 toes aside, and dwarf cultivars about two to 4 toes aside.
Rabbiteye bushes want more room, with no less than six toes between vegetation, however ideally extra. Lowbush blueberries may be planted one to 2 toes aside.
Most blueberries like quite a lot of moisture, and people which are rising within the wild can typically be discovered close to water, or in swampy or boggy areas.
Nonetheless, rabbiteye blueberries are extra drought tolerant and can undergo if given an excessive amount of water.
To complicate issues, blueberries have very shallow roots. Which means they dry out simply, so that they want constant watering.
Vegetation require one to 2 inches of water every week, relying on the species. You’ll be able to use a rain gauge to assist decide how a lot precipitation you obtain.
Should you don’t get that a lot naturally, you’ll want to offer supplemental irrigation.
Mulches like aged pine needles, wooden chips, and bark are perfect for serving to to retain moisture. Don’t use dyed or artificial mulches as a result of they might have a damaging influence on the surroundings.
![A horizontal image of a fallow section of the garden covered in organic mulch pictured in bright sunshine.](https://gardenerspath.com/wp-content/uploads/2021/03/Fallowing-a-Garden-with-Mulch.jpg)
Whereas it might be tempting, don’t use do-it-yourself compost round blueberries except you’ve checked its pH first – it’s often too alkaline for his or her liking. Manure-based composts are virtually all the time too alkaline, so it’s best to keep away from them.
In terms of fertilizing, wait till the vegetation have been within the floor for about six months earlier than you apply any meals.
Then, apply a tablespoon fertilizer formulated for acid-loving vegetation each six weeks, extending the fertilizer out 12 inches in a circle across the plant.
Arbico Organics carries Down To Earth’s Acid Combine, which is ideal for blueberries. It is available in one or five-pound packing containers – or pallets of 25 or 50 kilos, in case you’re planning on going large!

Down To Earth Acid Combine
Within the second 12 months, begin fertilizing proper as new development emerges and once more each six weeks. Apply two tablespoons of fertilizer per plant, extending 18 inches out from the middle.
From the third 12 months on, apply a cup of fertilizer per plant unfold three toes across the perimeter.
Keep away from utilizing industrial fertilizers or utilizing an excessive amount of fertilizer directly on rabbiteye vegetation. They’re significantly delicate.
We’ve extra information on fertilizing blueberry bushes right here.
Rising Ideas
- Plant in full solar.
- Keep soil pH of 4.0-6.0.
- Present 1-2 inches of water per week if rain doesn’t present it.
Pruning and Upkeep
Should you’re going to develop blueberries, you’ll have to change into good buddies along with your pruning instruments.
Common pruning is efficient for managing bugs, it helps to forestall illness, and it encourages extra ample harvests and bigger fruits. Plus, it makes it simpler to reap the fruits after they’re prepared to choose.
![A horizontal image of lowbush blueberries growing as a ground cover in rock garden with bright green foliage and ripe fruit.](https://gardenerspath.com/wp-content/uploads/2021/03/Lowbush-Blueberries-Growing-in-a-Rock-Garden.jpg)
Older canes produce smaller fruit and fewer of it. In addition they compete with the youthful, extra productive canes for diet and lightweight. In different phrases, they finally have to go.
One of the best fruit kinds on one-year-old canes and new shoots.
For the primary two years of a plant’s life, you don’t have to do a lot work. Simply take away the flower buds by snipping or rubbing them off.
You need the vegetation to give attention to maturing and growing somewhat than producing berries, tempting although it might be to see your first harvest as quickly as potential.
![A close up horizontal image of two hands from the left of the frame pruning a blueberry shrub in winter.](https://gardenerspath.com/wp-content/uploads/2021/03/Pruning-Blueberries-in-the-Winter.jpg)
Within the spring of the third 12 months when the plant continues to be dormant, take away any canes that cross, any which are twisted, or any which are rising low alongside the bottom.
Vegetation ought to absolutely emerge from dormancy by the tip of March in most areas, and also you need to full your pruning previous to this.
Take away any older canes that weren’t productive within the earlier season. To take action, simply lower the canes down cleanly on the base of the plant utilizing a clear pair of clippers or pruners.
Then, take away all however two or three of the most important, tallest, most strong new canes that had been produced within the earlier 12 months. New canes are small, pliable, and infrequently crimson or darker in shade than older canes. You’ll repeat this yearly.
As soon as the plant reaches its mature dimension, often round eight years of age, it is going to sometimes have about 10 to twenty canes of assorted ages in case you’ve saved up along with your pruning.
Going ahead, take away any diseased or broken canes every spring. Then, take away any older canes which are bigger than one inch in diameter.
They’ll seemingly be grey somewhat than brown or crimson, and the bark could also be peeling. Don’t take away greater than 20 % of the previous canes at a time.
If the plant appears crowded within the center, skinny out some canes to enhance airflow. As you probably did within the first 12 months, take away canes which are crossing and rubbing in opposition to one another every following 12 months.
You must also take away any canes that don’t have wholesome fruit buds and vegetative buds on the finish concurrently.
Blueberry canes can have each fruit buds, spots the place the blossoms and fruits will emerge, and vegetative buds, spots the place the leaves will emerge. Any cane that has nothing however vegetative buds or no buds in any respect needs to be eliminated.
How will you establish these? Fruit buds seem on the finish of cane shoots. They appear like teardrop-shaped, swollen buds that can kind into clusters of flowers and fruit.
Decrease down the canes from these are smaller, pointed buds. These develop new vegetative shoots within the following 12 months.
Put on protecting clothes while you’re pruning. Gloves, glasses, and a long-sleeved jacket are all good concepts, as a result of blueberry bushes may be tough.
When you’ve got a number of lowbush blueberries, you may merely mow a number of right down to the bottom annually with a garden mower or weed wacker.
The vegetation that you simply mow down received’t produce the subsequent 12 months, so that you need to ensure that to depart two productive vegetation alone and alternate mowing. In any other case, you may prune them as you’ll taller blueberries.
You might also need to trim the perimeters of the bushes to restrict how far out they unfold.
Be at liberty to offer rabbiteye bushes a haircut to be able to hold their peak low sufficient that you could attain all these berries. Simply don’t take greater than a 3rd of the peak off at a time.
In any other case, depart the vegetation tall and think about the upper berries a sacrifice to our avian buddies. They’re good to have round as a result of they hold bugs below management within the backyard – we’ll get right into a extra detailed dialogue of pests in a minute.
Blueberries of all species do finest with quite a lot of mulch as a result of it cools the soil and helps retain moisture.
Every year, you’ll want so as to add mulch in order that your bushes all the time have three or 4 inches at a minimal across the base (six inches is even higher), and prolong it out for 2 toes round them.
You’ll need to take away some or a lot of the present mulch earlier than you add some recent stuff.
The mulch needs to be flat across the canes, not heaping up increased across the base of the plant. Nevertheless it’s superb if the mulch is touching the canes – in truth, it needs to be in case you’re doing it proper.
