Hello guys..
I have a few 2 meter tall taxus baccata in my garden, which i want to dig up and make them into bonsai..

My question is, when the best time is to dig it up, and/or do a massive trunkchop?

My final height of the tree will be around 25cm.. When i do the trunkchop, should i cut it durectly down to the height, or shoukd i do it in phases over a few years?

Could you post some pictures of the trees?

Does it have green all the way to the ground?
Then chop and dig at the same time, in spring when the buds are swelling. Leave a decent amount of green, but make the main cuts (And leave some lower branches)
