Species, varieties and cultivars

Punica granatum (pomegranate)

It is a species native to Southeast Europe and Asia, currently cultivated for its fruits in most regions with mild climates. It has simple, deciduous leaves (in some regions the leaves are partially persistent), shiny, thick, with elongated, lanceolate shapes. The flowers are terminal, solitary or clustered in groups of two or three, red. The fruit (pomegranate) is similar to the apple in terms of shape and appearance, with a diameter of up to 12-13 cm. The skin is hard, first green, then red, and inside there are many small false fruits, with red, pink or partially transparent pulp. Each false fruit has only one kern. In the conditions of some temperate countries, the pomegranate does not produce fruit, it is cultivated only for ornamental purposes, in flower pots or in gardens.

Punica protopunica (Socotran pomegranate)

Originally from Socotra, Yemen, it is a species similar to the common pomegranate, with smaller fruits and more sour false fruits. Due to the inferior qualities of the fruits, this species has not been cultivated on a large scale outside its natural environment.

Environmental conditions

Light. It grows well in full sunlight.

Temperature. The pomegranate is adapted to the warm climate, and it does not tolerate well low temperatures. Negative temperatures severely affect pomegranate shrubs, if exposed to approx. -10 ℃, they dry irreversibly. In such conditions, it is recommended to bring the plant indoors for the winter, in a room with min. 10 ℃ and enough light.

Soil. It grows best on well-drained, light-medium soils. For ornamental cultivation, it is recommended to use flower soil or garden soil, mixed with sand and garden mould. It also grows on loamy, acidic, calcareous soils, and even on rocks.

Care

Watering. The pomegranate is resistant to the lack of water in the soil. However, in the case of cultivation for ornamental purposes, it is recommended to water the plants twice a week during the vegetative growth period, respectively once every 1-2 weeks during the winter. In the case of crops for fruit production, irrigation needs to be done regularly.

Fertilization. For vigorous growth, the occasional application of compost and specific fertilizers is recommended.

Propagation. It can be done by germination (from seeds) or vegetatively (by cuttings or grafting). Seed germination is difficult, seed propagation being recommended to be carried out by specialists in the field. In most cases, propagation is done by cuttings, because the pomegranate stems have a good rooting capacity. For summer cuttings, use stems that do not have inflorescences. They are cut and partially inserted into the ground after the application of rooting hormones, after which they have to be kept in unventilated spaces. For winter cuttings, cut the mature stem, 30-50 cm long, apply the rooting hormones, then â…” from the cutting is inserted into the prepared substrate.
