Hemp palms cannot be propagated vegetatively. You only get new offshoots if you sow seeds from the hemp palm. But until you get an offshoot to plant in the garden, you have to be patient. How to grow offshoots from hemp palms.
Hemp palms can be easily propagated by seeds
Harvest seeds for cuttings
If you cultivate several hemp palms, there is a good chance that you will be able to harvest your own seed for offshoots. You need one female and one male plant each. You can tell them apart by the color of the flowers. In contrast to the male, the female plant has light green flowers that look rather sparse.
Fertilization can only occur when both sexes flower. That doesn't work with care in the room. It's also safer outside if you do the insemination yourself. To do this, stroke the male and female flowers several times with a brush.
The seeds then form in the inflorescences, which you let dry before you can sow them.
How to sow hemp palms
Prepare seed pots (€16.68) with potting soil for the seeds. Soak the seeds in lukewarm water for at least a day to pre-swell. You can also rough them up slightly with some sandpaper.
The seeds are sown about an inch deep. Place the plant pots in a warm, bright place and keep the substrate nice and moist.
Further maintenance of the offshoots
- Put in new pots
- water regularly
- do not fertilize
- overwinter in a pot or tub
Once the offshoots have reached a height of four inches, plant them in slightly larger pots and continue to care for them like adult cannabis palms.
You must overwinter hemp palms in tubs for the first three to four years. Only when the offshoots are strong enough do they survive frost. Then you can plant them directly in the garden.
tips
It takes at least four years for an offshoot of the hemp palm to grow from a seed. It takes up to a year to germinate the seed. The young hemp palm needs another three years to grow into a robust offshoot.
