48-Ct Flat Spacing

Q: If you buy a 48 plant flat. How much room should you allow for that many plants?

A: It depends on the type of plant. Most annuals (ie Pansies, Vinca, Primrose, etc.) should be spaced approximately 4 to 8 inches apart. Some annuals spread a little bit farther, such as Petunias, and can be spaced farther apart. Perennial grouncovers (ie Cerastrum, Iceplant, etc) can be spaced even farther apart, around 12 to 18 inches.

So allow around 24 sq ft for a flat of annuals, and up around 48 sq feet for a flat of groundcover. You can, of course plant closer. Planting 4 inches apart will allow the plants to fill in quicker, which may be a good idea if you are planning for a wedding, or some other event.
