It's time to harvest one of my Greapfruit girls and I'm wondering how much do I need to flush the ground around the plant to get all the nutes out. She has been in the ground since 1 April and is just now ready to pull. I'm growing in Florida sand. Nothing else in the hole. Infect I didn't even dig a hole, just stuck them in the ground. I've been running water on the mound all day at a slow rate. Just enough to fill the area around the plant and keep it fullmas it drains down. How long do you think I should do this for?
