Subbed. I also have a "deck garden" in pots this year; 4 tomato plants, 2 zucchini, one yellow squash, and 2 jalapenos. Already harvested a yellow squash, 4 jalapenos, and many tomatoes. I over-watered the zucchini and they almost died....
I know one major change I'm making next year: bigger pots and I'll never use Miracle Gro potting soil for vegetable plants. The stuff is terrible, holds no moisture and is full of "filler", sticks, bark etc.
What kind of soil did you use Pete, and what size pots? Also, what are you using for fertilizer? The pots I'm using are about 10 inches in diameter and the same in depth. Just too small for the root systems, especially the squash plants.
I'm gonna try and find some large planters made specifically for patio gardens next spring.
I like the deck garden even though I have a huge backyard because we get so much hail; I can move the pots under the porch if we have storms in the forecast. They'd be destroyed by now without doing that!
