Like most other plants , blueberry bush have preferences when it come to what they ’re plunked into . They need well - enfeeble , free territory with deal of constitutive matter , as they ’re quite heavy feeders . Furthermore , like most other Charles Edward Berry flora , they demand acidic grunge with a pH of 4.5–4.9 to really thrive . In improper dirt , the plants may not flower or fruit at all .
quiz the stain in the area to gibe its pH layer , and amend if necessary . Remember that you could always remove the plants temporarily to work some sulfur , deep brown grounds , or peat moss into it to increase its sourness .
If the soil is too sandy or otherwise depleted , check that to play a heap of well - aged compost into it .

Many people constitute their berry bush around the outer boundary of their land , assuming that they ’ll get just enough igniter to be capable to produce . Sure , you might get some rudimentary growth , but they wo n’t flower or yield .
One of the most authoritative reason why we seek to observe country for a year before growing anything is so that we can see lightfall from season to time of year . A spot that gets plenty of sunshine in January might be completely shade out in June because of full tree foliage nearby .
If you ’re unsettled about where the gay patches on your property might be , then institute your blueberry in containers . These can be moved about as call for for optimal light vulnerability .
3. Stunted Plants, Dying Foliage
blueberry bush radical need to be consistently dampish throughout the entire grow season . If they get inconsistent lacrimation , the plant can get stress and wo n’t blossom or yield . Make certain to test the territory on a regular basis to ensure that it is n’t drying out . If you ’re expecting periods of hot , dry conditions , then set up an irrigation system so the roots are consistently watered at the grunge level .
In direct contrast , the plants do n’t care to have “ wet feet ” either . If your soil is sufficiently well - draining , then it should prevent the roots from rotting in overly wet earth . This is why it ’s so important to prepare the stain well before planting anything !
4. Blistered, Red, and Falling Leaves
Another potential issue is when leafage turn red during the raise time of year . Sure , this hue is carry in fall because the roots are re - absorbing delicious nutrients , but it should n’t bechance during the spring or summertime .
Blueberry folio singe ( Xylella fastidiosa ) is a bacterial virus that causes leave-taking to look burn . It ’s impart by aphids and can affect blueberry , cranberry , and Saskatoon berry plants .
rather of the gradual reddening that bechance in the fall , the leaves look like someone ’s taken a hyperbolize glass to them on a cheery day . foliage blister , redden , brown , and flow off . as luck would have it , this is a slow - developing exit that can be treated quite easy .
get rid of affected plants and incinerate them . Then get some cultivar that are certified virus - free , such as ‘ Olympia , ’ ‘ Bluecrop , ’ ‘ Ivanhoe , ’ ‘ Concord , ’ ‘ Reka , ’ ‘ Puru , ’ ‘ Nelson , ’ or ‘ Bluetta . ’ After that ’s done , take tone to keep your garden asaphid - freeas potential to preclude re - plague .
5. Flower and Leaf Death Before Recovering
Blueberry shock computer virus ( BlShV ) is transfer via infected pollen that ’s carried by bees , butterfly , and other fell pollinators . It ’s one of the many problem grow blueberries that is dominant throughout the Pacific Northwest , from southern Oregon through to British Columbia and Southern Alaska .
Symptoms are almost identical to blueberry leaf singe , except that the plants often recover and have a 2d foliar flush later in the season . In fact , they might even go on to assume fruit .
There ’s no “ cure ” for this virus other than to let it run its course . Most plant exhibit symptom for a few concurrent years and then develop an immunity to it .
6. Brown Blotches On Stems and Leaves

7. Plants Aren’t Producing Berries
Do you only have one blueberry bush bush ? If so , that ’s probably the main emergence . It ’s one of the uncouth problem newbies have when growing blueberry bush .
Blueberry George W. Bush are monoecious ( they have both manlike and distaff organs in their flowers ) and are thus consider self - fertile . That does n’t mean that they ’ll be tidy reproducing solo , however . They do far better when there are other plant life nearby for hybridization - pollination .
When there ’s abundant pollen from other plants , blueberries raise larger , sweeter , healthier fruit . essentially , it ’s expanding the gene pool for optimal offspring .

8. Berries Have a Grainy Texture or Sour Flavor
Grainy yield grain is generally due to inconsistent watering . Blueberry bushes are athirst plants and need a lot of piddle in society to acquire juicy , toothsome berries .

9. Yellow Stippling on Leaves, Frequent Diseases

course covers and bird netting can keep birds away from the berries passably easily . squirrel and other small creatures can be a bit more of a trouble . you could either fence in your berry with fine - gauge sword mesh , or scatter predator poop around the sphere to scare the critter forth .
13. Leaf Drop
One important affair to observe is that sometimes problems grow blueberries stanch from random conditions bug rather than computer virus or neglect .
For object lesson , my blueberry bush bushes drop all of their leaves after a freak July hailstorm a few years ago . An unexpected period of time of heavy rainwater can cause fruits to separate or can wash critical nutrients out of the soil .
Additionally , even if you take caution to wrap your bushes in burlap and mulch in prep for wintertime , that does n’t mean they ’ll be safe from animals during the cold time of year . Mice and other small rodent may burrow into the soil and nest among the roots , for example .
