Blueberries, when set in correct conditions can thrive for many decades.
But they can be quite high maintenance so here are some tips on how to get your blueberry plants up and running.
Soil and Preparation
In order for blueberries to really thrive, the soil must be in a certain condition. To begin, there has to be good drainage. Take a look at the soil after a rainfall or after being exposed to water general. If water stays and becomes a puddle in one area for more than a day or so, then that soil does not get enough drainage. The pH is also an important factor. Blueberries prefer soil that is acidic, ideally at a pH of 5.0. Some good things that slowly lower the pH of your soil are ammonium sulfate fertilizer, ground sulfur fertilizer, and sawdust from any conifer.
If you use the sawdust be sure to watch the nitrogen levels of your plants. If the leaves start to yellow then there could be a nitrogen deficiency. Other than those two things, just make sure the soil is nourished and enriched, such as with compost. When you begin planting, consider hilling the plants, which means raising them above normal soil level. This increases drainage and makes soil enrichment easier.
When you begin digging the hole for the blueberries you should dig one that is as deep as twice the size of the roots and then add compost. If not compost you can make a mixture of good bark mulch and peat moss. The peat moss should only be ten percent of the solution. When you are done planting then remember to remove about twenty-five percent of the branches to get stronger ones and continue to add compost to the top. This will build organic matter.
Other than all of this, you do not have to prune until about three years from planting. They require a lot of water so deep watering will be essential. The best time for fertilization is early spring.
