Garden Knowm Reviewed by Garden Knowm on . Is it necessary to flush? Is it necessary to flush my potted outdoor plants if I've been using Foxfarm products all along? For the last couple of months I've been feeding them Big Bloom & Tiger Bloom along with a worm casting tea. I know if you use chem nutes you should stop feeding two weeks prior to harvest. Rating: 5
