It took several days of soaking to get the peat hydrated--New Mexico. We firmed a handful of very wet peat completely around the cut--this is where two sets of hands are useful. It's not easy holding onto the stem, while keeping the peat in place until it's securely wrapped.
There are a number of commercial gadgets out there to accomplish this part, but foil has always worked fine for me. In Florida, the land of perpetual trickling sweat, foil was enough. Here in New Mexico, keeping the peat wet until roots emerge is tricky; I used a layer of plastic wrap, enough to cover the peat with a lot of overlap, with the ends twisted tightly around the stem.
The foil is wrapped over that, again tightly squeezing the ends shut to seal in moisture. I tied both ends snugly with twine just to be safe. Then we dragged the monster back inside.
Fast forward to mid-November. Roots have developed nicely, and none too soon; despite two layers of protection, the peat is drying out.
We've just finished potting up all the layers that we made in September. Although houseplants are not really our thing, we'll sell these next season when Mountain Gardens opens. For someone who considers herself an outside gardener, I seem to have acquired a lot of houseplants in sore need of division or cutting back.
Speaking of which--the monster was unfazed by our surgery. Maybe this time we'll use two layers of plastic.
