Hey! I recently repotted a young pyracantha tree and did the first root work. The height of the tree doesn't suit me very much and I thought about making two trees from one using air layering after 1-2 weeks. Is it advisable to layer on a tree that has recently undergone repotting and root work? The roots will pump water into the layering, but the parent tree will not receive nutrients from the layering (a product of photosynthesis). Can this weaken the parent tree?
