It feels like I’ve written this blog post before. Why can’t I outwit squash borers? I grow my squash from seed under grow lights. Tending them religiously, hardening them off before planting in my raised beds. I even rotate the beds. This year I had a couple of new beds at the community garden. They aren’t the best beds. Right under an old silver maple, they needed deep digging and now constant watering. But, I thought, there was no squash in this bed last year so I might have a fighting chance.
I did suffer something of a setback when I dropped the tray that held all the squash seeds I’d planted. I was working in the garage in preparation for bringing the tray inside to put it on a heating pad for plants to encourage germination.
I put the seeds back in the peat pots trying to match what I’d written on the craft sticks. Was this a Blue Hubbard or a zuchinni seed? In some ways it didn’t matter. I’d know soon enough once the plants were outside and began blooming and setting fruit.
Two zuchinni plants at the community garden were doing well. I got at least four small zuchinni, but today I began to see some yellowing on the leaves, a sure sign of borers at work. The other squash in that bed aren’t thriving. I do see a very small spaghetti squash coming along. Those vines should be covering that bed by now. Maybe that’s why that bed went unclaimed this year. But I didn’t give up. I planted more squash seeds. There’s still time for a squash harvest as we have late frosts.
The squash plants at home were doing extremely well. In fact, I have two blue hubbards and one naguri. Both the blue hubbards were doing well. I used some tomato cages I’d made from concrete reinforcing wire for the vines to climb on before I realized the blue hubbards can get huge. In my mind I was figuring out solutions to that problem. Then one of the blue hubbards didn’t seem to be growing. This morning this is what I saw.
The other blue hubbard is much larger and that vine okay. This is so disappointing. Commercial farmers are able to grow squash. What do they do to keep squash borers at bay? Everything on line is something I’ve tried except noxious chemicals – although I might consider… Once the leaves start to yellow, it’s too late to do anything. I wonder what immature blue hubbard squash tastes like?
But the real question is why do I keep trying? When every year the outcome is the same.
I suppose it’s partly because it’s a challenge and I want to figure out how to solve this problem. That may be some of my Viking heritage at play. Those men and women got on their ships and sailed out of the fiords and didn’t know what they’d find. It was a challenge. Of course, it was too cold to grow squash in northern Norway and they were looking for plunder and slaves, not a lovely blue hubbard squash to turn into the best “pumpkin” pie ever to grace a Thanksgiving table.
When the seed catalogs arrive next winter, will I be able to resist ordering squash seeds? Somehow I doubt it.
Have you tried spraying the plants with a little dish soap water once a week? Can’t hurt the plants and keeps the bugs away. I fight cucumber beetles every year with dish soap and win!!!

I haven’t tried that. Too late this year, but I know I will forget the pain and order squash seeds next winter.

It can be dis-heartening. Commercial growers use chemicals we’d rather not think about.

I know. Apparently it also helps if you have large fields of squash and the borers just attack some plants. That doesn’t work in my small raised beds.

I’ve had good luck with the Fordhook Zucchini variety in my area. Even after being attacked by borers it often roots from another spot on the stem and keeps producing. The yield may not be as good as a plant that wasn’t attacked but it’s still pretty good.
I’ve also had good luck using a spray made of garlic and chili peppers. Learned that from my Vietnamese in-laws and it’s been a decent alternative to chemical sprays. You have to apply it more often though and make sure the mixture you create is pretty concentrated.

Thanks, Patrick. It’s worth a try. I’m feeling desperate.

You have the same experience I did. The plants would be bountiful for a week or two, then die back overnight. So frustrating.
