Light Requirements
Englerina gabonensis (Engl.) Balle subsp. subquadrangularis (De Wild.) Balle is a shade-loving plant that thrives under partial sunlight or in areas with low light intensity. In its natural habitat, the plant grows under the canopy of other trees and shrubs. Therefore, it is best to place the plant in an area that is away from direct sunlight or to provide artificial shade if it is grown indoors.
Temperature Requirements
The plant prefers warm and humid conditions similar to that of tropical rainforests. Temperatures ranging from 20-30°C (68-86°F) are ideal for its growth. Extreme temperature conditions can affect the plant's growth and development, and it is best to keep the plant away from cold drafts or direct exposure to extreme heat.
Soil Requirements
Englerina gabonensis (Engl.) Balle subsp. subquadrangularis (De Wild.) Balle prefers a well-draining, nutrient-rich soil with a pH range of 5.5-7.0. A combination of peat moss, perlite or sand, and loamy soil would provide the ideal growing medium for the plant. Additionally, the soil should be kept moist but not saturated, as excess water can lead to root rot.
Cultivation Methods
Englerina gabonensis subsp. subquadrangularis is a shrub that grows well in humid and tropical regions. The plant prefers well-drained soils that are slightly acidic and rich in organic matter. It can be grown either in pots or in the ground, either from seeds or cuttings.
If you choose to grow it in pots, it's essential to ensure that the soil remains moist, but not waterlogged, as the roots can easily rot. On the other hand, growing it in the ground requires regular watering during the dry season to prevent it from withering.
Watering Needs
Englerina gabonensis subsp. subquadrangularis thrives in moist soil conditions, and it's essential to ensure the soil remains moist, especially during the dry season. However, it's recommended to avoid waterlogging, which can cause root rot.
To ensure that the plant receives enough water, you can add a layer of mulch to the soil around the plant's base. It helps to retain moisture in the soil and regulate soil temperature.
Fertilization
Englerina gabonensis subsp. subquadrangularis requires regular fertilization, especially during the growing season, to promote growth and maintain its health. A balanced fertilizer that is rich in nitrogen, potassium, and phosphorous is ideal for this plant.
You can apply fertilizer in various forms such as liquid, granular, or slow-release pellets. Ensure that it's applied at least six inches from the plant's base to avoid root burning.
Pruning
Englerina gabonensis subsp. subquadrangularis requires minimal pruning to maintain its shape and promote growth. It's recommended to prune it during the dormant season to allow it to recover from any potential stress due to pruning.
The pruning process involves removing any dead, damaged, or diseased branches. You can also prune the shrub to a desirable shape and size. However, avoid removing more than a third of the shrub's foliage at once as it can cause stress and inhibit growth.
Propagation of Englerina gabonensis subsp. subquadrangularis
Englerina gabonensis subsp. subquadrangularis is commonly propagated through seeds and stem cuttings.
Propagation by Seeds
Seeds of Englerina gabonensis subsp. subquadrangularis are usually collected during the fruiting season. The seeds should be sown immediately after collection, as they have a short viability period. The seeds should be lightly sown on a mixture of sand and peat moss or a well-draining potting mix. A covering of the seeds is not necessary as they need light to germinate. After sowing, the seeds should be watered lightly, and the pots should be placed in a warm and well-lit area. Germination should occur within 4-6 weeks.
Propagation by Stem Cuttings
Englerina gabonensis subsp. subquadrangularis can be easily propagated through stem cuttings. Select a healthy stem that is at least 6 inches long and has several leaves. Cut the stem just below a node, and remove the leaves from the lower half of the stem. Dip the cut end of the stem in rooting hormone powder, and plant it in a mixture of sand and peat moss or a well-draining potting mix. The cutting should be watered lightly, and the pot should be placed in a warm and well-lit area, away from direct sunlight. The cutting should root within 4-6 weeks.
