Acacias are a genus of plants with over 1,300 species native to tropical and subtropical regions around the world. Acacias are trees, shrubs or subshrubs characterized by spines, feathery leaves and yellow, white or pink flowers.
1. Choosing a landing site
Acacias prefer well-drained soils with a neutral or slightly alkaline reaction. Plants can grow in sun or partial shade, but they do best in full sun. Acacias do not tolerate stagnant water, so it is important to plant them in elevated areas or in areas with good drainage.
2. Soil
Acacias prefer fertile soils with a high humus content. Before planting, it is necessary to dig the soil to a depth of 20-30 cm and add organic fertilizers (humus, compost, peat).
3. Landing
Acacias can be planted by seeds, cuttings or seedlings.
Sowing seeds: Acacia seeds are sown in open ground in the spring, when the soil temperature reaches +10 °C. The seeding depth is 2-3 cm. The seeding rate is 20-30 seeds per 1 m².
Cuttings: Acacia cuttings are cut at the beginning of summer and planted in a greenhouse or greenhouse. Rooting occurs within 2-3 weeks.
Planting seedlings: Acacia seedlings are planted in open ground in spring or autumn. Seedlings are planted at a distance of 2-3 m from each other.
4. Caring for acacia
Watering: Acacias need regular watering, especially in hot weather. It is necessary to water the plants abundantly, without allowing the soil to dry out.
Feeding: Acacias need regular feeding. Plants need to be fed 2-3 times a month during the growing season. Mineral or organic fertilizers are used for fertilizing.
Pruning: Acacia trees do not need pruning. However, it can be carried out to form the crown of a tree. Pruning is carried out in spring or autumn.
Diseases and pests: Acacias are relatively resistant to diseases and pests. However, in some cases, plants may be attacked by the following pests:
- Spider mite: the pest feeds on the sap of leaves, causing the leaves to turn yellow and fall off. Insecticides are used to control the pest.
- Aphids: the pest feeds on the sap of leaves, causing the leaves to become deformed and fall off. Insecticides are used to control the pest.
5. Reproduction
Acacias are propagated by seeds, cuttings or layering.
Seed propagation: Seed propagation is carried out in the spring.
Cuttings: Cuttings are carried out throughout the growing season.
Layering: Layering can be done in spring or autumn.
Acacias are used for landscaping parks, gardens and other areas. The plants are also well suited to growing in containers.
