I have this project of going Hedera(Ivy) on Coco fiber mats for ground stabilization. BUT its a slow grower and went through a dormancy period here in the GH over the winter. I have already hit it with some 20/20/20 mixes, but not very hard and saw some positive results. How much fertilizer can Hedera handle. Can I put Urea on it to stimulate faster and more Lush foliage? I will take any and all comments.
