Squash vine borers are jerks. But...
Thanks to my step-bro-in-law Ashton, I now know what is killing my squash from within.
Just now, I used a sharp knife to slit open the affected squash stems, and I found 1-3 squash borer larvae per main stem.
Pulverized those jerks.
Now, I have all these squash plants that are all slit open like surgical patients.
I read today that bT (bacillus Thuringiensis) is an organic pesticide that can be *sortof* effective on these guys, but per this fellow, Tom Clothier, resistance is mostly futile and one should just give it up and prep diligently for a less moth larvae-ridden garden next year.
Thinking I will heap good, fresh soil and mushroom compost/erth food to cover the slit-open squash stems and hope they will heal? I don't want to give up.
Any advice on this would be much appreciated! Meanwhile, I'm gonna make some millet toast with almond butter on it. OMG almond butter. Why have I not loved you til now? Now I may love you a little too much.
