Ayy, that's fair. The prior owners set things up very nicely, so between that and other things, most of my gardening is "optional", which makes it very very nice; and many of the plants are forgiving / masochists (vines and roses).

Step 1: Learn how to trim new plant (holy crap they're algorithmic fractals!). Step 2: Start trimming new plant. Step 3: Go stare at newly-prior plant a few minutes a day, see how it's doing. 10/10 would recommend.
