With all the trees around my house it's hard to grow vegetables, but our deck gets maybe 6 hours of sun a day. In past years I've put up with watering each pot at least once a day. This year my husband ordered drip system equipment from the Drip Depot online. Of course it's rained more since I've put out the plants than it has in the past two years, so we haven't had to use it very much! I asked him to make the individual pot connections a bit long so I could move the pots to follow the sun.
