All of my winter squash have been killed by squash vine borers, even after using BT, injected, as a preventative measure.
Almost all of my cabbages were decimated by a groundhog - just as they were about ready to harvest, even though they were fenced and netted, with logs holding the netting in place. Stupid groundhogs! They got into my neighbor's garden, too.
Each sowing of peas and pole beans were thwarted by some kind of insect. I gave up after 3 attempts.
Our tomatoes are lack-luster. Very few fruits and they don't seem to want to ripen. I'm not really sure what's up, there. The plants seem otherwise healthy.
I coddled my summer squash along and got "some". Much more yellow squash than zucchini.
I had better results from my greenstalks. Not great, but better. Learned some lessons, there. Got lots of lettuces, cucumbers and bush beans. I'm making plans to improve results, next year.
My garlic did fantastic - but, garlic probably doesn't have a lot of pest-foes. I'm processing them for the freeze-dryer.
Overall, it's been a rather disappointing garden-season. I'd like to say it's because of something I could fix, next year. The pest-pressure was just too much. I couldn't keep ahead of it.
It may be time for me to give up on winter squash, altogether. I spent more trying to grow it than it would have cost just buying full-grown.
I'm hoping for a decent harvest on the potatoes and carrots. I have some celery growing, and it's looking puny, but not inedible. I replanted a couple of the greenstalks, so hopefully....
