| | Getting Ludwigia to Remain Rooted in Substrate
I'm having problems getting red ludwigia to stay rooted in the substrate. I am using Eco-Complete. It's growing incredibly well up top, especially close to the lights, but almost seems to be melting at the stem base. The leaves and shoots off the stem are still good lower down. It's just the stem itself. Any hints? It's driving me nuts because it starts floating and blocking the light.
