It is important to place the plant in areas where the temperature is consistent. During winter, the plant can tolerate temperatures as low as 45°F (8°C), but it should not be exposed to frost.
Soil Requirements
Pelargonium burgerianum J.J.A.van der Walt requires well-draining soil that is rich in organic matter. Soil that has a pH range of 5.5-6.5 is ideal for this plant. It can be grown in pots or in garden beds, but the soil should always be well-drained. Adding compost or organic fertilizer to the soil can improve its fertility and overall health.
Cultivation Methods
Pelargonium burgerianum J.J.A.van der Walt is commonly known as the Burger's Geranium. It is a perennial shrub that grows up to 1 meter tall. This plant needs a well-draining, sandy soil mix, and should be grown in a warm climate with good air circulation and access to sunlight. The Burger's Geranium prefers to be grown in a pot or container rather than directly in the ground to ensure good drainage and control of soil pH levels.
When planting, the soil should be irrigated well before planting the geraniums into the soil. It is recommended to plant during the summer months, as it is the best period for optimum growth and development of the plant. Watering should be done regularly, but care must be taken not to over water as the plant is susceptible to root rot.
Watering Needs
Pelargonium burgerianum J.J.A.van der Walt prefers to be kept consistently moist, but underwatering is preferable to overwatering. During the growth period, watering should be done at least once or twice per week, but the frequency will depend on the climate and soil moisture levels. The plant prefers to dry out slightly between watering sessions, as overwatering can cause the root to rot and can damage the plant. Always test the soil before watering, and avoid watering if the soil is damp enough.
Fertilization
Fertilization is essential for the growth and development of Pelargonium burgerianum J.J.A.van der Walt. Fertilizer should be applied during the growing season, which is from spring to early autumn. A balanced fertilizer with equal N-P-K ratio should be used, and it should be applied at a rate of 1 tablespoon per plant. Care should be taken while applying the fertilizer to avoid any harm to the plant. Overfertilization can be detrimental to the plant's health, causing the leaves to turn yellow and the root to rot.
Pruning
Pruning is a vital aspect of care in Pelargonium burgerianum J.J.A.van der Walt. Pruning should be done during the growing season to encourage the development of new growth and prevent flowering in later years. The plant should be pruned to shape the plant and remove dead, diseased or damaged stems, and leaves. Flowers should be removed when they begin to wilt to encourage the growth of the plant. Pruning should be done with a sharp and sterile tool to avoid any infection, and the tool should be disinfected after use.
Propagation of Pelargonium burgerianum J.J.A.van der Walt
