Which tank size is worth it in Minneola
Best fit: one 55-gallon barrel, which delivers about 402 gallons to the garden in a normal year (83.8% 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 Minneola's roof water will pass straight through it.
