Why Do Have Purple Flowers On My Blueberries

Question

Does this prevent growth – are they weeds and how do I treat them

Answer 1

Many cultivars will have a tinge of color to the flowers. Many will be white as well. Just be sure that you are feeding it correctly, as using any fertilizers containing nitrates (Like MiracleGro) will be a death sentence to the plant.

Ammonium sulfate will be what blueberries will want, rather than ammonium nitrate. Look for this, or just use a fertilizer that is already blended for blueberries. Here is an article that will help:
