Although hemp palms are basically hardy, it can still happen that the palm tree freezes after a hard winter. This is often reflected in brown leaves in spring. What sub-zero temperatures can hemp palms tolerate and what winter protection do they need?
In too harsh winters, the hardy frost palm can also freeze to death
What sub-zero temperatures can hemp palms tolerate?
Hemp palms are hardy down to a temperature of minus 17 degrees. However, this only applies to a hemp palm that is older and was planted outdoors in good time in spring.
The leaves of the hemp palm do not tolerate these sub-zero temperatures. They have already frozen to death if it has been colder than minus six to ten degrees in winter. But that's not too bad, since the hemp palm sprouts again in spring. As long as the heart of the palm does not freeze, the plant is not endangered.
Young hemp palms are not hardy. They must be overwintered indoors or in buckets for the first few years.
Brown leaves after winter
If the hemp palm shows brown leaves after the winter, this is not a big problem. It's just minor frost damage. Just cut off the brown leaves.
Palm heart frozen
It is worse when the heart of the palm is also frozen. This is shown by the fact that the middle of the hemp palm is also brown. Sometimes it can also be noticed that the trunk is soft.
If the heart of a hemp palm tree freezes, there is no salvation for the plant. You can then just dispose of them.
Protect hemp palms from frost and moisture
To protect your hemp palm from freezing, you should prepare it for the winter in good time. Spread a layer of mulch under the palm tree. Foliage and straw are well suited for this.
Cover the hemp palm with protective materials. Use sackcloth, fir branches, garden fleece, coconut mats (€21.90) or brushwood for this.
You overwinter a hemp palm in a bucket in a sheltered place on the terrace or balcony. A covered place is ideal so that the palm does not get too much moisture.
tips
Even more than the cold, the hemp palm gets too wet in winter. Make sure the heart of the palm is covered.
