I've got an Earthtainer with Squash planted in it. At first, everything seemed great, the Squash started growing and looked good, then, the ends of the Squash started to rot (turned brown and mushy). I has tried adding Clearex to the roots at the start, but as the plant has grown that has become harder. Any ideas, suggestions, solutions? I'd love to still be able to get some Squash I can eat from it - there are more still starting to grow.
