There's no magic solution to weeds. Some people use vinegar to kill weeds. This works on small annual weeds early in the season. But it won't kill tall weeds or perennial weeds. Pull them. And never use salt. You'll ruin your soil. Small weeds can also be eliminated by using a shuffle hoe. You really do shuffle it back and forth. It undercuts shallow-rooted weeds. I use "waffle" beds. These are vegetable beds that are below surface grade. They collect rain like the indentations in a waffle collect syrup. To water, you just lay the hose in the bed and let it fill up. It just takes a few minutes in my 4' X 4' beds. This uses water wisely. Because I water by hose, I need hose guards at the four corners of each bed. This prevents me from accidentally dragging the hose across the beds and breaking the plants. Old doorknobs decorate the hose guard posts. I've also turned strawberry jars into decorative additions. The jars are pretty much useless for growing strawberries but hens and chicks thrive in them. They survive outdoors with no winter protection. Cucumbers, peppers and yellow squash are producing well. When you pick them, cut rather than yank them off the plant. This prevents damage to the plants. If your tomato production is erratic, blame the heat. Tomato flower pollen dies at temperatures over 90 degrees. There's nothing to be done about it except be patient. When the heat abates, production will rise. That's why we have more tomatoes to pick in late summer and fall.
