You know too how lanky some plants get?
I gave all the Schlumbergera cuttings some pinches now that bloom is over.
I collected the pinched pieces to root, all with at least three leaf segments. If a piece fell off, I saved it too. Sometimes a single will root and grow; I try not to waste a precious bit.
Every pot within the cache pots had soil that had packed down an inch or better. I pulled out the whole plant and put new soil in the bottom of the pot, enough to bring the soil level almost to the top. Of course when you lift a plant, it no longer fits at the top because of the slanted sides. I carefully sifted more potting soil into the spaces around the edges.
There were enough cuttings to have a half-dozen of each color: pink, peach, yellow, white and scarlet. Six cuttings are perfect for making a Rainforest Sphere in the manner of Steve Asbell's Rainforest Drops. He hangs his, I set mine on an empty pot.
Steve puts unrooted cuttings into purchased grapevine balls filled with moss, I root first and then tuck rooted pieces into a moss-filled grapevine sphere made from collected wild grapevines.
Do what works, use what you have.
I left the Easter Cactuses for later after they bloom. They'll enjoy a haircut and some new soil sometime after Easter. Anybody that's rootbound gets a bigger pot but epi's are not wild about getting big pots, just a bit of a lift.
