Common household remedies request
My garden soil is full of mildew, TMV, name it, so part of my practice is to avoid splashing earth onto plant leaves wherever possible. And for my squash hills -- and I'm so proud of this, since I think for once I had a really original thought -- I recycled the tops of my wintersowing milk jugs: I just shove them into the hills top down, so they work like funnels. Then I can stick the hose into the milk jug and fill it up without splashing, and the water drains out the (capless) top, slowly if I throw some leaves in the bottom so the jug is more like a reservoir than a funnel.
So this works great, and my squash love it. Then I got the idea of adding stuff to the water, so I threw some dried blood in there, for nitrogen, and they loved that, too. So my question:
The squash are going to take up whatever I add to the water, and it's all going to be respired or incorporated into the flesh of the plant, one way or another. Is there anything natural I could add to the water that the kinds of insects that eat squash won't like? I'm thinking something stinky, like marigolds (although marigolds are not companion plants for squash).
NOTE Other milk jug tips. I especially like the one about burying jugs in the soil and filling them up periodically. It seems a lot more efficient than drip hoses, and it would target the individual plant. Reminds me of dew collectors in Dune.
