hi everyone,

all of a sudden my basil (sweet basil) plants suddenly wilt and shrivel. starting from the top. no bugs anywhere, at least not on leaves. soil is fresh from large bags. problem is only in one container. i grow the basil on the roof in NYC and gets good sun, water.
had just put in agri-fos, a safe fungicide, never had trouble before. other pots have same mulch, soil, water, agr-fos, etc but are healthy.

normally fungus would take a while to kill from what Ive seen. stem turns brown and plant slowly dies. this is first time the plant quickly wilted without brown or spots, etc.

wilting starts at upper leaves and droop over. stem curves down. bottom leaves healthy but soon wilt. only one section of one pot has trouble so far. all other plants are fine.

would anyone know what the problem is? i gave all the plants another agri-fos spray. the 1st spray i gave when there was no problem so that should have prevented any fungus. so this is a mystery.

when i pulled a wilting plant up the main root was nice and long. didnt see any bugs.

thanks

louis
