I have a Phal that is grossly overgrown and wondering if it is possible to propagate a new plant from a leaf cutting using a hormone powder. If there are directions for this process, I would love to see them.
I don't think this method is possible with most/any orchid. It's usually only successful if you have leaves, stems and roots all present on every part you wish to propagate.
If your phal has multiple growths with their own roots, perhaps you could divide it?
One of my den phals has sprouted two keikis on a damaged cane. Although the roots have grown to a couple inches and are numerous, green growth keeps dying off before becoming a leaf. The cane is now quite withered and I doubt if it can long provide energy to keep it up. Should I cut the keiki off and pot it even without leaves? How much of the cane should I include in the cutting?
you could try this.
Take half a paper towel and fold it down to an inch or 2 square, take one of the clamps used to hold up the spikes clamp the paper over the bud, and keep it wet occasionally.
Use an eye dropper to wet the paper.
