Some houseplants do not really fit into this category. Palms and cactus need to be looked at in a different way, so do not apply anything in this post to them. I received an email from a person who has a Schefflera arboricola bush, what she referred to as an Umbrella Plant. Some people also call the Schefflera arboricola a Parasol Plant or Dwarf Umbrella Plant. Anyway, the email I received was this:

Hello, I’m just wondering how to prune an umbrella plant. My plant is getting out of control, growing upwards and I can’t seem to get it to grow like a bush. I’m afraid to cut it to shape cause I might kill it. I’ve had this plant for over 10 years and from the picture I sent you can see it’s still growing good. I just want to trim it down but I want to do it properly. Thanks!

My answer to her follows…

When pruning an Arboricola (umbrella plant), cut just the stem, just above a leaf node. I usually cut the tallest stem back into the center of the plant, leaving some leaf nodes below the cut for new growth to start. Doing this every once in awhile keeps the plant fuller and shorter.

You can cut the really tall stem that you have growing past the top of the door to maybe 12 inches or so in height. Cut just above a leaf node.

Cutting it should not kill it, it will just promote some new growth from the stem that you cut. It also keeps it from getting so tall that the stems start to fall over.

I usually cut anything that has gotten tall enough or leggy enough that it no longer can stay upright without some type of support.

Also, turning the entire plant/pot once a month will help to keep it growing evenly on all sides, resulting in full, even growth all over the plant. Hope this helps, send along any other questions.

Pretty easy to do. I have added a picture of the Arboricola plant that she sent with the email. The pink Xs are the two stems that I would cut back right now. It is hard to tell if the tallest stem is growing directly from the soil or is a side shoot from another stem. If it is a side shoot it can be removed from the stem it grows out of. The smaller green lines are where I would cut, approximately.

You should always use sharp, clean, if not sterile, pruners when you cut your plants. Just like people, plants can get bacterial diseases, viruses, and fungal disease and they can be spread through infected tools.

Keeping your houseplants pruned, trimmed, and shaped helps keep them fuller looking. When you remove part of a stem, it releases growth hormones below the cut and helps to promote new, healthy grow on your plant. An over grown plant can also be a big problem if it ever needs to be repotted.

Keep your houseplants in shape and you also help keep them healthy and growing!
