no flower buds on impatiens grown from seed

Question

I have 72 beautiful impatient plants grown from seed that are about to be planted in baskets and the ground. None of them have flower buds and they are already about 5″ tall. Will they eventually flower?

Answer 1

Yes, you should have blooms. You can apply a light phosphorous bloom booster fertilizer when transplanting into the larger containers.
Blood Meal is a good why to do this. Follow application directions on packaging.
