Patti Moreno, the Garden Girl, shows how to install a drip irrigation system in a container garden for growing herbs and vegetables. Container plants also need more fertilizer. First, at the spigot, connect a manifold/timer with a fertilizer dispenser and a filter to remove particles. Then run a half-inch main tube line to the patio, using clamps to secure the tubing to fencing and elbow joints at any corners. For each container, punch a hole in the main tube and attach a quarter-inch tube with a joint, then attach an optional valve partway down the quarter-inch tube. Attach pot drippers, down spray sprinklers. Or soak tubing as appropriate to each plant at the end of each quarter-inch tube. Turn the system on then go on vacation!
