Thought I should write an update to blueberry care...
1)Fertilize - within the next 2 weeks. Use Amonium Sulphate (NH4)2 SO4 Sprinkle around the perimeter of the roots. I basically think of this as the perimeter of the plant branches. Do NOT sprinkle on the roots as you might "burn" the plant. Use about 1 cup for large bushes and 3/4 cups for medium size bushes.
2)Mummy berry prevention should be done when the buds break. E-mail me if you need specifics.
3)Water as needed, ha, ha, ha .....(this is an inside joke for all of us who live in the NorthWest...)
4)Mulch is helpful in hot weather to hold in moisture... ha, ha, ha (Another NW inside joke)
Feel free to e-mail me or "comment" if you have more questions. Anne
