Nice planner. I like using drawing tools with layers. For garden planning it makes it easy to update things as you go. Keep a snapshot photo each time you update, and you'll have a garden journal, so you can look back at your progress of what you have done in the past.
Sometimes seeds won't all come up in the nice perfect arrangement I had planned, so I like to return every week and put new seeds into the empty spots where nothing came up. Might be a bit wasteful, but works for me if in containers where I want lots of something growing in a cluster all summer (carrots, cilantro, anise, daisies).
