i had a chia lin that rotted where the bulb meets the roots. it turned black and leaf and all fell off. when i checked the roots, they were rotten. this happened very quickly.
i treated it with physan 20 twice when i first saw it and it didn't even slow it down. i had isolated it, too. how much trouble is my greenhouse in. i have had trouble with all the chia lins i have tried to grow.
