We're rolling out a new cloning feature today that will significantly increase your productivity in cases where you have the same or similar types of garden beds or plantings.
It's simple and straightforward: click on the item you want to duplicate, and you arrive on that item's detail view. Next to the existing button in that view, there's a new button; clicking the Clone button will create a copy of the graphic on the map, and populate the information in the form. There may be times where you want most all of that information to stay the same, and there may be times where you'll need to go in and modify particular details; this gives you that flexibility. When you're satisfied with your choices, click Save as usual.
