I've also been putting down black mulch to kill the grass off, so that I can triple the size of the garden next year. Pulling the tomatoes today. Always a sad time for me.
We just had a freeze - finally - and I pulled my tomatoes as well. End of October for maters is really strange but wow it has been a nice autumn.
Tell me about the black mulch...what is it and does it really work?
The black mulch is just black plastic. I lay it over the garden, pin it down, and then bury the edges making it totally immobile. Then I just put holes in where I want to plant things. This keeps the area completely weed free, and heats the soil. Important for me is preventing soil from splashing onto my plants when it rains, which is where a lot of diseases stem from. You can buy colors other than black, which are supposed to do various things like metallic silver reflects light in a way that keeps insects away, while also reflecting light into the canopy of the plant spurring more growth. As opposed to landscape fabric, water cannot get in through it, so it works really well with a drip setup. I used the black mulch a little bit this year on my brambles and ribes, and saw these benefits right away. Having seen quite a few commercial setups this year that use black mulch, I will say it works quite well.
