Since my well had to be capped due to an oil spill in the area (don't even get me started), I am exploring new, more sustainable watering. Last year, with the drought I wasted so much with overhead watering and the weeds were ridiculous. Anyway, I am exploring drip irrigation and will at the very least invest in some rain barrels this year. So my question is, how can I control algae and mosquitos in the stagnant water? Can I use bleach? How much? will it harm my vegetables? Also wondering if anyone has any ideas on cheap barrels. Rain barrels are expensive. Can I just put a spicket on a garbage can? metal or rubbermaid? Thanks so much!
