Install a simple irrigation system for the new pots to make them low maintenance. You can purchase the whole kit at your local home center for around $30. First, cut the tubing to length and put a barbed connector on one end and a drip head on the other end. The kit comes with a hole-punch to cut small holes in the water hose for the drip tubes. Make the holes and push the barbed connector through the holes to connect the drip tubes. Next place drip tubes in each of the pots, putting two or three drip heads in each one. Turn on the water to make sure the system is working and the plants were getting plenty of water.
To make sure your pots don't dry out, attach a hose timer to the water spigot. The timer will let you choose when to water the pots and for how long to let the water run. Attach the new drip system to the timer so that the plants will be watered even when you're not around or you forget to turn the water on. Set timer to run everyday for 15 minutes. This will be enough to keep the pots moist, but not too wet. The nice thing about a drip system is its flexibility. You can move your pots and drip heads around, you can change the timer and mostly your garden will be stress-free.
