What's a good time to water the garden? I used to time the sprinkers to go
off at 4am and the last station (I have several beds) finishes at 5am.

But it takes awhile before the water soaks into the ground so I changed it
to 12 midnight. Now, I'm thinking of shifting it to 9pm so that I can
observe how the sprinkers are working before I goto bed.

My garden beds are a mixture of roses, azeleas, lavenders, poppies (for
remberance day).

Cheers!
