I have many different ones for copious different uses. A superbloom, rose, tomatoe, houseplant (20-20-20 and 10-15-10 and some others) and other different formulas for getting my african violets to bloom. I also have fertilizer for acid loving plants close to azalea, rhododentron and hydrangea. Which formulation would be best. Should I use one to promote growth when the leaves are growing and then switch to a more flower friendly formula? Their growing and blooming season is short until I get my green house. I live surrounded by US garden zone 6 and have to bring them inside the house for dormancy from early November through in the order of May. Actually, all I have right very soon are 1st year rooted cuttings. May 3 year, which has bloomed in yesteryear, got a bit of root rot and I had to cut it and reroot it and regard as I've lost it. Oh well.

Answers:    Of course you can always purchase some fertilizer at the home and garden stores, but Wonder finds that the homemade characteristics works best.
