Pelargonium anethifolium grows well in well-draining soils that are rich in organic matter. It prefers slightly acidic to neutral soils with a pH level between 5.5 and 7.5. A mixture of sand, peat moss and perlite can be used to improve the soil texture and enhance drainage. This plant does not tolerate waterlogged soil and should be kept away from areas with poor drainage.
Watering Requirements
The watering requirements of Pelargonium anethifolium vary depending on the growing environment and the season. During the growing season, this plant should be watered once a week or when the top layer of soil is dry to the touch. In winter, watering should be reduced to once every two weeks. Overwatering can lead to root rot, while underwatering can cause the leaves to wilt and lose their color.
Fertilizer Requirements
Pelargonium anethifolium benefits from regular fertilization during its growing season, which is from spring to summer. A balanced fertilizer with an N:P:K ratio of 10:10:10 can be applied every two weeks. The fertilizer should be diluted to half the recommended strength to prevent burning the roots. Avoid fertilizing during the winter months when the plant is dormant.
Cultivation Methods
Pelargonium anethifolium is a beautiful plant, but it requires a bit more attention compared to other species of the same genus. The plant prefers to grow in well-draining soil that is rich in organic matter. It is recommended to select a pot that is at least 6 inches wide and has drainage holes at the bottom.
This plant tolerates various light levels, from partial shade to full sun. But make sure to protect it from extreme heat and strong winds. It is essential to maintain a consistent temperature and protect the plant from too much cold exposure.
Watering Needs
Pelargonium anethifolium's watering needs vary depending upon multiple factors, including the temperature, humidity, light, soil type, and pot size. It is best to check the soil's moisture level before watering the plant.
Ensure to keep the soil slightly dry to avoid root rot. Overwatering can be detrimental to the plant's health. It is recommended to test the soil with a finger, stick, or moisture meter to determine if the plant needs water.
Fertilization
Pelargonium anethifolium requires proper fertilization to grow healthy and vigorous. Use a balanced fertilizer that contains all the essential nutrients like nitrogen, phosphorus, and potassium. Fertilize the plant when it is actively growing, usually from spring to autumn.
Avoid over-fertilizing the plant, leading to salt build-up in the soil. You can use a slow-release fertilizer or dilute the fertilizer and apply it every two weeks to prevent any potential damage from excess nutrients.
Pruning Pelargonium anethifolium
One of the benefits of growing Pelargonium anethifolium is how easy it is to prune. Pruning helps to maintain a compact shape, prevents the plant from getting too leggy, and encourages new growth.
Annual pruning is recommended, usually performed in spring to remove any dead, diseased, or damaged branches. You can also pinch back the tips of the branches to encourage bushier growth and increased flower production.
When pruning, utilize clean and sharp tools, and make sure to disinfect them between each cut to avoid spreading diseases.
Propagation of Pelargonium anethifolium (Eckl. & Zeyh.) Steud.
Pelargonium anethifolium can be propagated through different methods.
Seed Propagation
Seeds of Pelargonium anethifolium can be collected from the plant when they are mature and dry. The seeds must be sown in a well-draining soil mix and kept moist until they germinate. Germination usually occurs within 7-14 days, depending on the temperature and humidity. Once the seedlings have grown to an appropriate size, they can be transplanted to individual pots or directly into the garden.
Cuttings
Pelargonium anethifolium can also be propagated through stem cuttings. The best time to take cuttings is in the spring or early summer. Select a healthy, non-flowering stem and make a clean cut just below a node. Remove the lower leaves and any flower buds. Dip the cut end in rooting hormone and plant it in a well-draining soil mix. Keep the soil moist and provide a humid environment by covering the cutting with a plastic bag or a cloche. The cutting should root in 3-4 weeks and can then be transplanted.
Division
Another way to propagate Pelargonium anethifolium is through division. This is best done in the spring when the plant is actively growing. Carefully dig up the plant and separate the individual rosettes. Each rosette should have some roots attached. Plant the divisions in a well-draining soil mix and water them thoroughly. They should establish themselves quickly and start to grow.
