Add peat moss to your soil to ensure proper nutrients and soil drainage. You should till 3 to 4 inches of the peat moss into the soil, at a depth of 6 to 8 inches.
Plant your blueberry shrubs about 4 to 5 feet apart in a row. When not using mulch, you should plant the shrubs 1 or 2 inches deeper in the soil.
Water the plants using a soaker hose. This ensures each plant receives adequate water throughout the growing season.
Prune blueberry bushes back to allow only the strongest one to three shoots to grow.
Fertilize blueberry plants carefully. Too much fertilizer can quickly damage the plant. You should apply 12-12-12 or 10-10-10 NPK fertilizers in a circle around plants each six weeks.
Place mulch around the plants to prevent weeds and control moisture. About 3 to 4 inches is preferable for mulching.
