Pelargonium hollandii F.M.Leight. thrives best in a bright and sunny location. It prefers to be kept in an area with plenty of natural light, however, direct sun may cause sunscald on its leaves. Therefore, it is best to place the plant in a spot where it can receive morning sun and afternoon shade or dappled sunlight to prevent scorching or leaf damage.
The ideal temperature range for Pelargonium hollandii F.M.Leight. is between 60°F to 80°F (16°C to 27°C). Although it can tolerate fluctuations in temperature, it should be kept away from frost, strong winds, and sudden changes in temperature. Thus, it is best to avoid placing the plant near a window or a drafty area during the winter season.
Soil is crucial for Pelargonium hollandii F.M.Leight. to grow and thrive healthily. It prefers well-draining soil that is slightly acidic and rich in organic matter. The soil should be well-aerated to prevent waterlogging, which can lead to root rot. A suitable potting mix for Pelargonium hollandii F.M.Leight. can be a combination of peat moss, perlite, and vermiculite.
Cultivation methods
Pelargonium hollandii F.M.Leight. also known as Cape Pelargonium, is a plant that requires full sunlight throughout the day. It thrives well in well-draining soil with a pH of 7.0 or lower. It is best to plant in the springtime in a hole twice as large as the pot, making sure that the root ball is well covered with soil without overcrowding it. The distance between two plants should be about 30 to 45 cm.
Watering needs
The watering style and quantity of water depend on the stage of growth and the season of the year. Watering moderately in the summer and sparingly in winter is the best idea. The topsoil should be dry before adding water, to provoke root growth and help avoid fungal growth.
Fertilization
The Cape Pelargonium plant does not need a lot of fertilizer. An organic, low-nitrogen fertilizer is preferable every two weeks throughout the peak growing season. Water-soluble geranium fertilizer, which has a balanced nutrient ratio of nitrogen, phosphorus, and potassium, is ideal for these plants. It is advisable to use half of the recommended dose as severe feeding will cause harm to the plant.
Pruning
Pruning Pelargonium hollandii F.M.Leight. should be carried out to remove any dead leaves or flowers, which can cause fungal disease issues or weaken the plant. The ideal time to prune is during late winter or early spring, which is the dormant phase. In summer, you need to pinch back leggy stems to promote bushy growth or middle-aged stems with crossing branches to allow air circulation and light penetration. Pruning should be conducted above the leaf nodes with sharp and clean tools to prevent damage to the plant.
Propagation of Pelargonium hollandii F.M.Leight.
Pelargonium hollandii F.M.Leight. is a unique plant that adds beauty to any garden with its delicate flowers and lovely scent. Propagation of Pelargonium hollandii F.M.Leight. can be done through various methods such as cuttings and by seeds.

Place the pot in a warm, bright location and keep the soil moist. It may take several weeks for the seeds to germinate, and once they have, the seedlings must be transferred to larger pots before transplanting them to the ground.
Propagation of Pelargonium hollandii F.M.Leight. through cuttings is the best method for a faster growth, while propagation through seeds is good for growing a large quantity of plants.
