Gardening with kids

I just got into gardening since we are new to having a yard, but spending time outside, doing slow, quiet, low pressure work has been a lovely way to spend time with my kids. At 3 and 6 they can both find things that interest them, and there is lots of mud and water to play with when they need a break from digging and planting. Bonus if you have popsicles in your freezer which are a crucial for cooling down!
