Thank you! I have done a lot of research. I can't find a link to the specific SIP that I built. It was in my Family handyman magazine. You can google Sub irrigated planter. They work a lot like the Earthtainer.
Well then, I will remove all of the rubber mulch today. I will run the Home Depot to see if they have any organic mulch.
Well that is good to know about the black krim. You know, I haven't started fertilizing yet with the seaweed emulsion. When shoud I start? After they start to flower?
Thank you to everyone who has posted!
UPDATE: I changed out the rubber mulch for a hardwood mulch today!
