Drip irrigation- I do this every year and it works great! Especially during a long Texas drought- less water waste. The only thing that kept my plants going, and once the plants get growing they hide the bottle.
keep shells in open container in fridge. When full, crush shells into small bits and sprinkle around base of plants. Sharp eggshells will deter slugs, snails, and other bugs from nibbling on garden and add touch of calcium to soil.
