Lindsey, sorry to hear you have fusarium problems. Be sure to wear your protective clothing - hat, glasses, mask, long sleeves etc. when you're spraying those scary fungicides! Some of them are really bad for you to get on you, or breathe.
I'm not so far seeing any problems with my orchids, but something has killed off all my tomato plants - even though I planted disease-resistant hybrids. Argh. Think I'll give the Earth Boxes a douse of my Actinovate biologic fungicide and plant a few more plants to see if I can get a few more tomatoes before summer really kicks in.
