Botrytis and copper fungicide - questions
Do bulbs transmit botrytis? I.e. do I need to dig up bulbs after a bad case of botrytis?
ALSO, is treating it with copper fungicide too toxic? If the copper is in the soil, will it prevent lilies from growing next year?
Really need to know answer to these questions, because I dusted the ground with the copper fungicide after I dug up diseased plants. Can I plant new bulbs in the same area after doing this?
