My late husband grew incredible bougainvillea and hibiscus plants. He made a fertilizer out of white ammonia, saltpeter, epsom salt and baking powder but I don't remember the proportions. Does anyone have this recipe?
I'm not sure exactly what the chemical is for saltpeter, but you get it via your pharmacist. The ammonia is the one WITHOUT detergent -- just household ammonia. Clear if you can find it, which I never can, but the white seems to work also. If I can get them scanned, I'll post pictures of my late husband's bougenvillia. They were always incredible using this formula!
