What is the proper way to trim stem plants? (ludwidia, et al)

I have had mixed luck trimming my stem plants

Parrot feather - I've had issues when lopping off the top 1/2 or 2/3rds. As they grow, the bottom leaves just die. Sometimes I get a new growth head started from the very top by the cut point. Others, nothing.

Camboba - this guy is very stem-heavy. It is roughly 2 - 2.5" between leave groups. Trimming him has been hit or miss.


I have had luck trimming/splitting didiplis diandra. Actually, the bottom of the plants die and I'm left with floating stems which I then separate and replant.

Penny wort has been pretty easy to trim and replant the clippings.


I have some Ludwidia Repens and Ludwidia Atlantia which I'd like to split, but don't know how high or low to cut the plant. At the moment they don't need a trim, but do want to grow more of these guys.

Thanks!

I'm curious about this too. Do you clip and re-plant both the bottom and the top? Or do you clip and re-plant the top or clip and re-plant the bottom? The bottom always looks sad after I clip but I feel bad when I throw away the bottom with all the roots the plant developed.

I have used the basis that if the root / bottom stem is still stiff (not mushy) then it is still alive and might grow. I've left just bare stems w/ no leaves but healthy roots and eventually will get new shoots. Other times, they eventually die.

Also, do stem plants like root tabs? I don't have any but am considering for my madagascar lace (which is really growing slowly)

I clip the top off and put it in the substrate next to the bottom. The bottom then grows more stems and the patch of whatever it is gets really thick. Stems do like root tabs, but they can live without them. The madagascar lace would probably appreciate the root tabs.

Hi sphack et al,

Here is a simple to understand, well explained explanation of how to trim stem plants to achieve that dense, bushy look we see in the AGA winners; enjoy!

This might get better/more responses if it were in the plant subsection of the forum. You'd need to ask an admin to move it.

I have had mixed results with stem plants, I'm also curious about this.

Are you supposed to cut right above or right below a leaf node when trimming or does it matter.

And when replanting I have read that you are supposed to remove the bottom leaves that would other wise be buried in the substrate and I have seen where people say to keep the leaves and bury a couple to help anchor the plant till the new root growth takes hold.
