I have 3 African Violets and they have been very healthy all winter but no blooms. I tried Epsom Salt diluted in Distilled water and watered them. I held my breath while doing this because I was terrified to ruin my AVs. It worked. My “Harmony’s Cotton Candy” started to show blooms within 2 days and today looks about to bloom. My purple AV has flower buds now but not as close to blooming as the Cotton Candy. So excited. First time having Blooming AV!!!!
