My WP was delivered late September 2006 in time for my 40th. It looks great, but how old are these trees now? It’s wintering under the low eaves of the house, sheltered from the worst of Anglesey’s wind and rain. I have stood the original pot in a larger pot with a couple of inches of gravel for drainage and straw between the pots to insulate the roots. I will cover the top with fleece if we get frost. I want to encourage a multi-stemmed plant (like the larger WP I have seen at Kew and Tresco Abby) to live in a large pot, at least for a few years. I have read about the plants’ plasticity, but how can I encourage new main shoots without butchering the existing one: a good low P feed, light from the side, or will it just happen naturally as it grows? Any suggestions welcome.
