While there is not first or last date to fertilize blueberry bushes, the general rule of thumb is to fertilize blueberries in the spring before their leaves have grown in. This is so that the blueberry fertilizer has time to penetrate the soil and make it to the roots of the blueberry bush before it enters active growth. You should be fertilizing blueberries once a year. Typically, they do not need fertilizing more often than this.
Meters to measure pH levels as well as test soil kits are widely available to help with any necessary adjustments during the growing season. Planting blueberries in the ground is different. The best way to plant a blueberry in the ground is to dig a hole about 2-1/2 feet wide and 1 foot deep. Ed also recommends removing the native soil. Use the same soil blend Ed used for the containers, but mix in native soil from the hole.
