|I'll be out of town for 10 days. How can I keep my house plants watered during that time?
|Using plastic water bottles as a source of drip irrigation works well. You might want to try using them before you actually go on vacation, just to make sure they deliver enough water to keep your plants growing well. Water the containers well first, then fill plastic water bottles with water and turn them upside down with the open tops buried into the soil two or three inches. Capillary action will draw the water from the bottles into the soil. Test to see how many bottles your plants will require to keep the soil reasonably moist.
