Keiki orchid ready for separation from mother plant
Phalaenopsis keikis are generally considered ready for potting once they have 2-3 leaves, and roots that are at least 3 inches long. The roots on this 1-year old keiki are approaching 5 inches in length, and if they continued growing out any farther, then I would have struggled to find any pot to fit them. It is time to remove the little guy from the mother plant, and pot it on its own.

I cut the keiki from the spike with some wire cutters, sprinkled cinnamon over the cut to prevent infection, and left the keiki to soak in a tub of water for 10 minutes. The water was treated with Superthrive, which should hopefully encourage vigorous root growth.

Soaking the roots in water helped soften them so that I was able to (just barely) curl the 5-inch roots into a 3-inch clear plastic pot. Although these roots are long, there are only two of them, and I worried that any larger of a pot would take too long to dry out.

The keiki is now potted in a 3" clear plastic pot, with phal bark mix. I will now log it as a separate plant: Phal noid 'keiki 1'.
I am trying something a little strange but possibly helpful with my second largest keiki. Its roots are about 3" long, and I want to wait a little longer before removing it. In an attempt to get the roots to curl into a pot-friendly shape, I tried strapping a plastic pot to the keiki while it's still attached to the spike. This makes the spike quite top-heavy, so I added a support stake. I'll see if this is more helpful than it is ungainly. I expect to separate this keiki in another month.
