HELP! Why am I killing my Begonias???
I just bought a house and have always wanted to have a lavish garden and test my green thumb. While at Logee's I fell in love with these begonias and thought I would give it a whirl. I seem to be doing well with the other plants but these Begonia's are TOUGH! I wish they would talk to me.... They did great for the first few weeks. I potted three of them in the same terracotta dish that is probably 5 - 6 inches deep and about 12 inches wide. I used an organic quality potting soil & some of my compost (horse & chicken) and I used a slow release fertilizer. I don't water them until the top layer gets dry (maybe every two weeks). Some how I've acquired gnats - in all my house plants (my guess is that is from the compost). I'm going to get some mosquito dunks to fix that but not until i determine what is wrong. At first they started getting brown and curly on the ends which after some research i decided was not enough humidity but then they developed these spots. I think it must be some type of fungus that i have given them. So i striped off all the leaves that had the spots on them which left me with about 2 per begonia. Now all the leaves are gone (partially due to my dog) but the stems do appear to be growing new leaves. What should be my next step? Should i pull the plants out of the soil completely and let them dry? Replant them in a better soil? I have perlite & peat moss i was thinking would work better than the compost. I guess i should have researched before i planted them. Here is a picture of the spots and the plants before i plucked the spotted leaves off. Ill take a picture when i get home of what they look like today but they are just stems.... HELP!!??! They were beautiful when i bought them and i feel bad that I've done this to them. I bought a China Curl, Raspberry Torte, & Ring of Fire. Can i plant these outside in a shady spot for the summer?
