Coast redwood cutback and repotting

I’ve been engaged on a big coast redwood for the previous few years in suits and begins. After an preliminary pruning and repotting (see “Coast redwood” for particulars) I’ve labored on the tree in earnest a number of occasions solely to let it develop out once more.

After a number of cycles of this, I eliminated nearly all the branches so I may restart the method from scratch.

My targets for creating the tree are to ascertain new main branches and enhance department density – a course of achieved rapidly with frequent pruning and pinching. By protecting the branches I wish to ramify brief and letting the branches I wish to thicken develop freely, I can pursue each targets directly.

As a result of the tree has grown a lot prior to now two years, it was in want of a repot. I’d solely repotted the tree as soon as earlier than so I needed to scale back the bottom of the trunk (which had been resting on the underside of the pot) and take away as a lot of the outdated soil as potential.

Right here’s what the basis ball seemed like after eradicating 1-2 inches of wooden from the bottom of the trunk.

I’d hoped to plant the tree in a shallower container however I didn’t have any pots that have been proper for the tree so I returned it to the unglazed oval it had been rising in.

I don’t anticipate the tree to develop a lot till the climate warms up, however when it does begin rising, I’ll try and work on it at any time when it wants a trim.
