My latest gardening "issue" is that some of the huge leaves on my zucchini
plants have "dirty" spots. It looks like they were splashed with dirt...but
it's not dirt. I am growing these in EARTHBOXES, so the soil should be OK
and the fertilizer situation should also be right. Any ideas?
It's a wormy thing that chews into the main stem near the soil line. By
doing so, it destroys the plant's means of drawing up water. The plant
begins to sag, as if it needs water. You water, but it makes no difference,
and the next day, it's dead. Some years, it doesn't happen. This pest is a
good reason to keep mulch a foot away from the plant on all sides.
I didn't say that was what was going on. I simply responded to your question
about borers. :-)
And, the fact that you're capitalizing EARTHBOX repeatedly would seem to
indicate that you want us to think it's somehow isolated from certain garden
problems. It is NOT. You said the "soil should be OK" and the "fertilizer
situation should also be right". Why???
OK, you make valid points. But MY point is that at least with the EARTHBOX,
there is SOME expectation that the soil and fertilizer are at least somewhat
standardized. Anyway, my lower leaves seem all "dirty" but the fruit
continues to develop nicely.
Well, the materials may be standardized when they're brand new, but when the
bugs want you, they find you, and they laugh at whatever precautions may
have been taken. Meanwhile: How is the fertilizer applied with the system
you're using? Powder? Liquid? Sprayed? Poured? Lobbed in from 20 feet away,
like a basketball?
The moth that lays the eggs of a nite don't care how high they are. I
use BT on the stems of mine up until July when the moths are done. I
know what is BT. It is emzine that kills catrpilers. You can get it at
any big garden store, great for keeping tham off of cabbage also.

Yes. Squashes and cucumbers are likely to get borers. I usually
sprinkly a little rotenone around the new plants and later on, along the
If you do get a borer, you'll see orange stuff like sawdust. Take a
pocket knife and split the stem until you find and kill the borer. If
you bury the stem at the split, it may send out roots from that point.
