We've had the 12 bushes in our flower bed for 3 months. They're growing but no blooms. We auto water 3x a week for 3min. Used a general fertilizer 3 weeks ago and when first planted. They had blooms when we bought them buy as they grew healthy and green no more purple blooms!

A couple of light feedings, half strength, a year with a multi-purpose fertilizer or once in early spring with a slow release multi-purpose fertilizer is all this plant needs. Too much fertilization will encourage plant growth, putting strength into growing new foliage leaving little for new blooms.
Sunlight will also affect the plants blooming. This plant needs at least 6 hour of direct sunlight a day to bloom well. This is especially true in the spring and early summer to start a good blooming season.
Once established, which your plant should be, the Sweet Pea Shrub only requires moderate to little water. Too much water will slow blooming and in time too wet a soil can kill the plant. Many times too much water will show up in a yellowing of the leaves.
