The hemp palm comes from China, where it can get very cold in winter. This palm species is therefore hardy and can also be grown outdoors all year round. Some winter protection is still useful. Potted plants tolerate less frost and must be protected over the winter.
The hemp palm is very hardy
Winterize the hemp palm in the garden
The longer a hemp palm grows in the garden, the more robust it is. Temperatures down to -18 degrees are no problem. Frost damage can appear on the leaves without the palm suffering.
The hemp palm in the garden is more affected by the moisture in winter than the cold. Therefore, you should winterize hemp palms by wrapping the plants with garden fleece or burlap and laying a thick layer of mulch made of leaves, brushwood and fir branches around the palm.
Overwinter hand palms in tubs
In the bucket, the hemp palm tolerates temperatures down to -6 degrees. If it doesn't get colder, you can overwinter the palm tree on the terrace.
At lower temperatures, however, you should bring the hemp palm indoors. Find a spot that is bright and not too warm. It should not be warmer than about ten degrees at the winter location. Avoid strong temperature changes. The hemp palm would not do well directly from the cold into the warm room.
Hemp palms that you grow as a houseplant, keep them cooler over winter and water less. But the location must be very bright.
tips
Young hemp palms are not yet hardy. They may only be planted outside in the garden when they are at least three or four years old. In the first year they need a particularly good winter protection.
