What do you recommend for automatic indoor watering of plants while on vacation?

I simply up-end plastic water bottles to keep my containerized houseplants hydrated. Your success will depend upon how large/thirsty the plants are and how long you'll be gone. I hope you have some time between now and your vacation to do some experimenting. Start by throughly watering each plant. Allow excess water to drain and then up-end a bottle of water into each container (stick it into the soil up to its shoulders). When the soil begins to dry out it will wick the water out of the bottle. In my 2 gallon containers a 16 ounce water bottle keeps the soil moist for about 2 weeks. If you have larger containers or extra thirsty plants you may need to use 2-3 bottles per container. Try it out now so you'll have some idea of how long the water lasts in each container. Hope it works as well for you as it does for me.
