Proper drainage prevents water accumulation that drowns roots and creates disease conditions. Gutters and downspouts direct roof runoff away from foundation. Interior floor drains handle irrigation runoff and condensation. Gravel or perforated pipe underfloor systems provide emergency overflow. Adequate drainage maintains operational efficiency by preventing muddy conditions that hinder worker movement and plant care. Good drainage also protects foundation integrity from water saturation and freeze damage. Regularly clean gutters and test drainage systems before each growing season.
