Blueberry Planting Instructions
Note: The plants won't use this phosphorus immediately now but in a year when their roots get into that zone they'll really like it.)
Note: If you are planting in spring, mix the remaining mixture with two cups of the organic fertilizer (see below). Never fertilize your plants in fall as they become susceptible to winter damage.
Finally fill the hole with the plant in it, with the remaining mixture in such a way that it mounds. The blueberry plant should be 3-4 inches above the ground level and the soil should mound from the crown. This allows water to drain away from the crown. Planting the bushes higher than that helps with root diseases but makes the plant susceptible to drought in summers. Tap the soil slightly around the soil to restore water capillary system. Water deeply, immediately. In spring I would use either a soluble fish fertilizer (Alaska) or Miracle grow. Again don't use this if planting in fall to avoid winter damage.
Regular Care after Planting
Spring
Fertilize about 2 cups per month per plant of the below from March to June
Summer
Water regularly each week from mid-June to Sept. East of cascades, may require even more water.
Winter
Prune the plants after their second year any time when they are dormant. Preferrably in Feb.
Organic Fertilizer
