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 bottles. Quick and easy way to fertilize too!
(the original person who wrote this) just started this on Friday night and I already have 1/2 inch of new onions growing! That's only 3 days! "The next time you have green onions, don't throw away the white ends. Simply submerge them in a glass of water and place them in a sunny window. Your onions will begin to grow almost immediately and can be harvested almost indefinitely. just use kitchen scissors to cut what need for meals."
