Hi,

I have a rooftop container garden with a southwest exposure that keep
drying out, and I am tired of having to constantly water it. What can I do
to keep the moisture levels up, (and my time investment down)?


A friend of mine has been growing a container garden for the last few
years. This year, she switched mostly to self-watering planters like
these: http://www.naturalspring.com/natsprinplan.html

She still has to water regularly, but she thinks the reservoirs helped
a lot.
