Barrel or cistern in Winter Garden?

Best fit: one 55-gallon barrel, which delivers about 214 gallons to the garden in a normal year (85.8% of its need).

If you buy one, a 55-gallon barrel with a downspout diverter is the whole job. Check that the overflow points away from your foundation, because most of Winter Garden's roof water will pass straight through it.
