Pomegranate trees are not only known for their delicious and nutrient-rich fruits, but also make excellent ornamental plants. If you don’t have a large garden, don’t worry! Pomegranates can be grown in pots, so urban gardeners and those with limited space can enjoy growing them. Here’s a step-by-step guide for growing a pomegranate tree from seed in a pot:
1. Collect seeds :
- Choose a ripe pomegranate : Choose a fruit that is firm, brightly colored, and free of blemishes.
- Extract the seeds : Halve the pomegranate and carefully scoop out the seeds.
- Clean the seeds : Place the seeds in a sieve and run cold water over them to remove any pulp that may be stuck to them.
2. Preparation of the seeds :
- Soak overnight : Place the cleaned seeds in a bowl and cover with water. Let them soak overnight.
- Stratification (optional) : This process involves placing the seeds in a damp paper towel in a plastic bag and refrigerating them for several weeks. It can increase the germination rate, although pomegranate seeds often germinate without stratification.
3. Sowing the seeds :
- Choose the right pot : A 6–8 inch pot with good drainage is ideal to start with.
- Prepare the soil : Choose a well-draining potting soil, which you can buy or make at home from equal parts compost, sand and peat moss.
- Sow the seeds : Place the seeds about ¼ inch deep into the soil and make sure they are at least 2.5 cm apart.
- Water lightly : The soil should be moist and not soggy.
4. Care of the seedlings :
- Sunlight : Make sure your pot is exposed to at least 5-6 hours of direct sunlight daily.
- Watering : Keep the soil evenly moist, but not soggy. Once the seedlings have grown a few inches, you can reduce the frequency.
- Protection : While pomegranates can tolerate some cold, it is best to protect young plants from sub-zero temperatures.
5. Transplanting and pruning :
- Size matters : When your tree outgrows its original pot, transplant it into a larger one or plant it directly on the ground if space allows.
- Pruning : Once your tree reaches a height of about 30 cm, you should prune it to encourage branching. This will create a stronger foundation and promote better fruiting in the coming years.
6. Fertilization :
- Use a balanced, slow-release fertilizer, preferably organic. Start fertilizing in spring and continue throughout the growing season. Avoid overfertilizing, however, as this can hinder fruiting.
7. Possible challenges :
- Pests : Look out for aphids, whiteflies and mealybugs.
- Diseases : Pomegranate trees are relatively hardy, but can occasionally suffer from fungal infections. Ensure good air circulation and avoid overwatering.
8. Harvest :
Patience is key! It may take several years for your tree to bear fruit, especially if grown from seed. But once they appear, wait until the pomegranates have turned a deep color and sound slightly hollow when tapped before harvesting.
Growing a pomegranate tree from seed in a pot is a fun endeavor that even those with limited space can tackle. With patience and proper care, you’ll be rewarded with both striking foliage and delicious fruit. Happy gardening!
