Definitely add as much mulch as you can, it can make a huge difference. Dig a swale to catch some water when it rains, then the water will gradually seep into the bed. If there is a roof near your garden, catch rainwater off it. For an already planted garden, those are the main things I can think of. Anyone else have any ideas?

Hi, I was wondering if you could answer this question for me :D Are there any water/moisture saving techniques you know for an already planted garden, aside from mulching?
