The plant should be planted at the same depth as its original container and spaced at least 30cm apart. It is advisable to mulch the soil around the plant to conserve moisture.
Watering needs for Pelargonium marlothii R.Knuth
Pelargonium marlothii R.Knuth needs occasional watering, and its watering requirements increase during the flowering period. Deep and infrequent watering is ideal as the plant does not tolerate waterlogging and excessive moisture in the soil.
Water the plant once a week and monitor the soil's moisture level using a moisture meter or by inserting a finger into the soil. Increase watering during hot and dry weather.
Fertilization for Pelargonium marlothii R.Knuth
Pelargonium marlothii R.Knuth can benefit from occasional fertilization during the growing season to promote healthy growth and flowering. Use a balanced fertilizer every 2-3 months or a slow-release granular fertilizer every six months.
Avoid over-fertilizing the plant as this can lead to excessive vegetative growth at the expense of flowering.
Pruning Pelargonium marlothii R.Knuth
Pelargonium marlothii R.Knuth needs minimal pruning as it maintains a manageable size on its own. However, you can prune it to promote bushier growth and increase flowering.
Prune the plant after the flowering season by cutting back the stems by a third. Remove any dead or diseased wood, spent flowers, and crossing branches.
Propagation of Pelargonium marlothii R.Knuth
Pelargonium marlothii R.Knuth, commonly known as Marloth's pelargonium or Leeubekkies, is a popular South African succulent plant that belongs to the family of Geraniaceae. It is commonly propagated through seeds and cuttings.
Propagation through seeds
Pelargonium marlothii R.Knuth can be propagated through seeds that are readily available from online nurseries or garden centers. Sow the seeds during early spring or late summer in well-draining soil and cover them with a thin layer of sand. Water them regularly and keep the soil damp but not waterlogged. The seeds will germinate within 8-14 days.
Propagation through stem cuttings
Pelargonium marlothii R.Knuth can also be propagated through stem cuttings. Take a 4-5 inch cutting from the top part of the plant during the growing season, preferably in spring. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in well-draining soil and keep it moist. Place the pot in a warm and bright location, but not in direct sunlight. The cutting will root within 4-6 weeks.
Propagation through cuttings has a higher success rate than propagation through seeds. However, it is still important to take care of the cuttings to ensure their successful establishment.

The following are some of the common diseases that might affect Pelargonium marlothii :
Botrytis Blight
Botrytis blight is a fungal disease that causes gray mold on the plant's stem, leaves, flowers, and buds. The disease thrives in cool, wet conditions, and can spread quickly if not managed early. To manage Botrytis blight, prune the infected parts of the plant and avoid overhead watering. Maintaining good airflow and reducing humidity around the plant can also prevent the disease's spread.
Leaf Spot
Leaf spot is a fungal disease that causes circular brown spots on the plant's leaves. The disease can spread rapidly, and the affected leaves may eventually drop, causing defoliation. To manage leaf spot, remove the infected leaves and destroy them. Avoid overhead watering and ensure that the plant receives enough sunlight and airflow. Applying a fungicide can also help control the disease's spread.
Common Pests
The following are some of the common pests that might affect Pelargonium marlothii :
Spider Mites
Spider mites are tiny pests that suck sap from the plant's leaves, causing yellowing and browning. The infested leaves may also have a web-like coating. To manage spider mites, use a forceful stream of water to blast them off the plant. Applying insecticidal soap or neem oil can also help control their populations.
Mealybugs
Mealybugs are small, white, cottony pests that can infest the plant's leaves, stem, and flowers. They suck sap from the plant, causing yellowing and wilting. To manage mealybugs, remove and destroy the infested parts of the plant. You can also dab a cotton swab dipped in rubbing alcohol on the mealybugs to kill them. Applying insecticidal soap or neem oil can also help control their populations.
