The pomegranate plants are preferably propagated by cuttings. Propagation by sowing is also possible, but is not always successful in terms of flower and fruit formation. On the other hand, plants grown from cuttings produce abundant flowers as young plants.
What is the best way to propagate pomegranate plants?
Pomegranate plants can be successfully propagated by cuttings or sowing. Cuttings prefer fertile plants, while sowing from seeds is possible but may bear less fruit. Constant humidity, heat and light are important for both methods.
Basically, new pomegranate plants can be easily propagated from both seeds (generative) and cuttings (vegetative). However, the hobby gardener should be aware that the pomegranate tree grown in this way may not have the desired characteristics in terms of flowers, fruit, size, vigor, etc.
The rich-fruiting or weak-growing varieties available in specialist stores are offered as refined trees. In horticulture, grafting is the process by which two plant parts - a rootstock and a scion - are combined to form a plant with the desired properties.
Vegetative propagation preferred
For this you need one or more cuttings from a pomegranate tree. They are cut in early spring before new growth appears. Leafless side shoots about 10-20 cm long are suitable. These are placed in a planter with potting soil or a nutrient-poor and loose sand-peat mixture. For optimal root formation, the substrate should be kept constantly moist and the temperature should not fall below 20°C. The cutting roots after about 4-6 weeks. As soon as it has leaves, you should repot it.
Generative propagation possible
The pomegranate season in Germany is between September and December. This time can be used to grow new pomegranate plants from seeds of ripe pomegranates. Sowing is successful with the following steps:
- Remove the seeds and remove the pulp,
- if applicable Allow to soak in warm water overnight,
- Put the seeds in a planting container with thoroughly watered soil, do not cover with soil,
- Sowing warm and bright, keeping the substrate evenly moist.
Depending on the substrate temperature, the seeds germinate after 2-3 weeks. The seedlings also need temperatures of around 20° C and lots of light to develop. Watering is slightly less than during germination, but the substrate should not dry out completely.
Tips & Tricks
To keep the temperature and humidity constant, an indoor greenhouse (€24.00 on Amazon) is ideal. You can also cover the container with seeds with cling film. It should be ventilated underneath occasionally.
