Cut Back After Bloom & Re-pot For Dwarf Hand Grafted Weeping Pussy Willow - April 16, 2022

Purchased this last year and my husband has kept it indoors till early summer. It is much happier outside in the sun. Last spring, my husband pruned it to a few inches from the center top. Turned out to be successful. We were not expecting it to have lasted as long as it has. This year, I am pruning the same way but about an inch or two further. Additional work this year is the root prune. I am finding most of my container plants loose their vigor when root bound. An expert in keeping container roses has demonstrated the cutting of the bottom layer. I am betting that this will work for other container plants. Taking a risk! No expert here but trying to make things work.
