I've been looking around for Fatshedera for years! How can I cultivate my own? How is it done? Thank you!
I would do a Google search for plants. You could also check Ebay, they are often a good source for more unusual plants.
Here is a link with more information on Fatshedera.
I have a Fatshedera that has over time lost all its leaves along the stem. I have pruned it, however, the new growth is only on top. Is there a way to stimulate new growth along the bare stem?
That is a common occurrence in tree ivy. You can cut off the top to encourage branching and lower leaves. Keep pinching new growth to keep it bushy.
