Cultivation methods for Pelargonium ovale (Burm.f.) L'Hér. subsp. ovale
Pelargonium ovale (Burm.f.) L'Hér. subsp. ovale, also known as the Rose-Scented Geranium, is a popular plant among horticultural enthusiasts. When it comes to cultivating this plant, it is important to keep in mind that it thrives best in warm and sunny climates.
Therefore, to cultivate the Pelargonium ovale (Burm.f.) L'Hér. subsp. ovale, one should aim to provide a warm and sunny environment for the plant. Ideally, the plant should be placed in a location that receives full sunlight or at least six hours of direct sunlight daily. It is also important to ensure that the plant is planted in well-draining soil as the roots of the plant may rot if they sit in water for extended periods.
Watering needs for Pelargonium ovale (Burm.f.) L'Hér. subsp. ovale
When it comes to watering, the Pelargonium ovale (Burm.f.) L'Hér. subsp. ovale should be watered moderately. This means that the plant should be watered when the top inch of soil is dry to the touch. It is important to avoid over-watering the plant as this may cause root rot. On the other hand, under-watering the plant may cause its leaves to droop or wilt.
Fertilization of Pelargonium ovale (Burm.f.) L'Hér. subsp. ovale
For optimal growth, the Pelargonium ovale (Burm.f.) L'Hér. subsp. ovale should be fertilized every two to three weeks. Ideally, the plant should be fed with a balanced fertilizer that contains equal amounts of nitrogen, phosphorus, and potassium. It is important to avoid over-fertilizing the plant as this may cause the leaves of the plant to become yellow, indicating a nutrient burn.
Pruning of Pelargonium ovale (Burm.f.) L'Hér. subsp. ovale
To encourage bushier growth, the Pelargonium ovale (Burm.f.) L'Hér. subsp. ovale should be pruned regularly. This can be done by cutting back the plant's stem tips by a third. Dead or diseased leaves should also be removed to prevent the spread of disease to other parts of the plant. Additionally, by removing spent flowers, the Pelargonium ovale (Burm.f.) L'Hér. subsp. ovale will continue to produce new blooms throughout the growing season.
Propagation Methods for Pelargonium ovale subsp. ovale
Pelargonium ovale subsp. ovale, commonly known as the rose-scented geranium, can be easily propagated by seeds, cuttings, and division.
Seed Propagation
The seeds of Pelargonium ovale subsp. ovale can be sown in spring or summer in well-draining soil. The seeds should be placed 1cm deep in the soil and kept moist. Germination may take anywhere from 7 to 30 days, depending on the temperature and humidity levels. Once the seedlings are large enough to handle, they can be transplanted to individual containers or a well-draining garden bed.
Cuttings
Cuttings taken from Pelargonium ovale subsp. ovale in spring or summer will root easily. Take a 10-15cm cutting from the tip of a healthy stem and remove the lower leaves, leaving only 2-3 pairs at the top. Dip the cuttings in rooting hormone powder and insert them into a well-draining potting mix. Keep the mix moist and place the container in a bright, warm area, out of direct sunlight. The cuttings will root in 4-6 weeks and can then be transplanted to their final location.
Division
Pelargonium ovale subsp. ovale can also be propagated by division. Divide the plant in spring, just as new growth starts to emerge. Gently lift the plant from the soil and separate the root system into smaller sections, being careful not to damage the roots. Each new section should have at least one healthy stem and a good root system. Transplant the new sections into individual containers or a well-draining garden bed and keep them moist until they become established.

- Fungal infections: Fungal diseases, such as powdery mildew, botrytis blight, and root rot, may cause the leaves, stems, and flowers of Pelargonium ovale (Burm.f.) L'Hér. subsp. ovale to wilt, discolor, or develop spots. These diseases are often triggered by high humidity, poor air circulation, or overwatering.
- Viruses: Viral diseases, such as the tomato spotted wilt virus and the impatiens necrotic spot virus, may cause stunted growth, distorted leaves, and yellowing of the foliage of Pelargonium ovale (Burm.f.) L'Hér. subsp. ovale. These diseases are often spread by sap-sucking insects, such as thrips and aphids.
Common Pests
Pelargonium ovale (Burm.f.) L'Hér. subsp. ovale may also be targeted by some pests that may damage its foliage and flowers:
- Spider mites: Spider mites may infest the leaves and stems of Pelargonium ovale (Burm.f.) L'Hér. subsp. ovale, causing them to turn yellow and dry out. These pests are often found in hot and dry conditions.
- Aphids: Aphids may suck the sap from the leaves and stems of Pelargonium ovale (Burm.f.) L'Hér. subsp. ovale, causing them to curl and distort. These pests are often found in cool and humid conditions.
- Mealybugs: Mealybugs may attach themselves to the leaves and stems of Pelargonium ovale (Burm.f.) L'Hér. subsp. ovale, secreting a waxy substance that may lead to the growth of black mold. These pests are often found in crowded and unventilated conditions.
