What size rain barrel for Wadsworth
Best fit: one 55-gallon barrel, which delivers about 300 gallons to the garden in a normal year (77.6% of its need).
If you set one up, a 55-gallon barrel with a downspout diverter is the whole job. Check that the overflow points away from your foundation, because most of Wadsworth's roof water will pass straight through it.
