As spring nears, houseplants

No matter that winter winds and snow still come and go in much of the country. The sun’s earlier rising and higher climb into the sky let us know that spring is on the way. Even houseplants indoors feel the changing season.

Take a closer look at the stems of your houseplants. Any young, new leaves? Swelling buds? Inside their pots, roots might likewise be awakening. All of this makes today, tomorrow, or sometime soon a good time for repotting and pruning.

How tall is too tall?

The most obvious reason to prune a houseplant’s stems is to keep the plant manageable. For example, growing in the ground in a tropical climate, branches of weeping fig, a familiar houseplant, will reach skyward and spread as high and wide as a sugar maple’s. Indoors, at the very least, your ceilings limit the desired height of a houseplant. For looks, you might want to keep the plant smaller, perhaps much, much smaller.

When pruning the stems of a houseplant, the goal is to reduce its size without giving it a hacked-back look. For a plant with many stems, such as a weeping fig, a few severe cuts usually gives better results than many small cuts. Trace one of the tallest stems down to its origin, and cut it off right there. Perhaps do this with another tall stem too.

After one or more drastic cuts have lowered the plant, go back over the plant to make some smaller cuts. Cut back any dead or diseased stems, and any that look gawky or out of place.

There are houseplants, such as dracaena and ponytail palm, that naturally sport only one or very few stems. These rarely need pruning; when they do, it’s because they’ve finally grown too tall. Lop back the stem to lower than the final desired height. New growth
