A late spring frost, on the other hand, can injure partly opened flowers, causing a partial to total crop loss on some early-flowering cultivars. These early cultivars are not recommended for areas that typically receive late spring frosts. If the pH of your soil is greater than 5.0 but less than 7.0, you can increase the acidity with applications of sulfur or acid peat. Contact Cornell Cooperative Extension - Suffolk County for information on having your soil tested. At the same time, incorporate organic matter such as peat moss particularly if the soil is very light and sandy.
Blueberries are difficult to propagate, and survival of rooted cuttings is poor.
Commercial nurseries are recommended as the source of plant material. The roots of potted blueberries must be pruned before planting. Place plants in the soil as soon as they arrive in early spring. It is beneficial to soak the roots for several hours before planting. Separate plants by a minimum of 4 feet within rows and 10 feet between rows.
