@BardfromtheBookshop I've been planting #TreeGuilds for about 30 years and can recommend many possible options. The 'rule of thumb' is to include #pollinator attractants, pest repellants, #nitrogen fixers and #fertilizers, mulch producers, grass suppressants, and so on. Daffodils should almost always be included as they are toxic to burrowing #rodents like voles which can kill a tree. Sharp gravel all around the roots, when planting, will also protect them from root munchers. Your particular #climate and #soils will determine your best choices. Good suggestion, @heathen about spreading the roots to avoid self-strangulation. Also be certain to NOT bury the graft, not even in mulch. I have lots of specific plant suggestions but will await your reply.
