What size rain barrel for Wildwood
Best fit: one 55-gallon barrel, which delivers about 440 gallons to the garden in a normal year (86.9% of its need).
Before you buy, a 55-gallon barrel with a downspout diverter is the whole job. Check that the overflow points away from your foundation, because most of Wildwood's roof water will pass straight through it.
