Start the preparation of your site as early as possible, autumn is the ideal time. A position in full sun is ideal though they will tolerate some shade. Mix in good amounts of well rotted compost and organic matter, and you can take advantage of the frosts to break down the compost even more over the winter so that you are ready for planting in spring. The soil for growing blueberries needs to be a well draining acidic type in the pH range of 4.0 to 4.5.

Water them in generously and promote good root growth by keeping nice and moist over the next 2 months. After that, a couple of inches weekly during summer will prevent them drying out.
Bushes take at least three years to produce fruit and any fruit that appears before this should be removed to encourage the plant to grow stronger and produce greater harvests in the years to come. Once the fruit has turned blue on a mature bush, you should leave it up to a week before harvesting to allow it to fully ripen and develop a sweet taste.
Maintenance is minimal; add fertilizer in springtime and to promote next years buds fertilize again in late summer. Your blueberry bush should thrive for many years.
Pests and diseases are not too much of a problem when growing blueberries; aphids and caterpillars might need spraying on the odd occasion or you can handpick them off, however, birds can create havoc, as they just love those juicy berries. We recommend you use Garden Netting if you want a share of your fruit.
When growing blueberries you will find that they tend to overproduce so pruning is essential for a good healthy tree, sure you will get less fruit, but you’re compensated with larger berries.
Start your pruning in late winter when the plant is dormant. First look for and remove diseased or broken branches to the base, also look for dead branches which will be a grey looking color as opposed to red, with no buds on and cut these back to the main trunk. Then look for branches which are crossing each other and cut these off to the main trunk also. This allows that essential airflow through the tree, and also improves sunlight reaching the fruit. Keep the bushes to a height you can manage as this makes it easier to pick your berries and to apply the netting. It’s essential you do not cut away more than 50% of new growth.
To help maintain the acidic value of the soil that is used for growing blueberries you can top-dress with fir or pine sawdust.
