Rain is your friend
The weather man says rain today. I say BRING IT ON.
I planted lots of petunias, Diascias, Lobularias and impatiens this weekend, and already had put squash, cucumbers, tomatoes, peppers, basil, parsley, and corn in the ground. And I divided and transplanted a bunch of perennials. Even moved a rose bush at the absolute worst time possible. I just couldn't bear to look at it where it was for a whole season.
Sure would be nice not to have to water when I get home.
