Temperature Preferences:
This plant species does well in moderate climates with temperatures ranging from 10-25°C. While it can tolerate cold weather, it cannot survive in areas with consistent freezing temperatures. It is also sensitive to heat stress and requires regular watering to prevent wilting and leaf scorching.
Soil Requirements:
Alchemilla elgonensis Mildbr. x A. johnstonii Oliv. ex Hell. thrives in well-draining soils with a slightly acidic pH between 5.5-6.5. The soil should be rich in organic matter and have a good water holding capacity to ensure adequate hydration. Soil that is too heavy or compact can obstruct root growth, impeding the plant's ability to absorb essential nutrients.
Cultivation Methods
Alchemilla elgonensis Mildbr. x A. johnstonii Oliv. ex Hell. is an herbaceous perennial plant that thrives in USDA hardiness zones 8-10. It prefers well-draining soil with a pH range of 6.0-7.5 and partial to full sun exposure. The plant can be grown from seeds or propagated through division. When planting from seeds, it is recommended to start indoors and then transplant outdoors after the last frost. The spacing between plants should be about 12-18 inches apart.
Watering Needs
Alchemilla elgonensis Mildbr. x A. johnstonii Oliv. ex Hell. requires consistent moisture during the growing season. It is important not to overwater, as this can lead to root rot. Watering should be done when the top inch of soil is dry. The best time to water is in the morning or early evening to prevent plant stress from the hot sun.
Fertilization
It is recommended to fertilize Alchemilla elgonensis Mildbr. x A. johnstonii Oliv. ex Hell. once a month during the growing season with a balanced fertilizer. Avoid over-fertilization, as it can lead to excessive foliage growth and reduced flower production. The plant can also benefit from a layer of organic mulch around the base, which can help to retain moisture and suppress weed growth.
Pruning
Regular deadheading can help to promote more flower production in Alchemilla elgonensis Mildbr. x A. johnstonii Oliv. ex Hell. It is also important to remove any dead, damaged, or diseased foliage throughout the growing season. At the end of the growing season, the plant can be cut back to the ground.
Propagation of Alchemilla elgonensis Mildbr. x A. johnstonii Oliv. ex Hell.
Alchemilla elgonensis Mildbr. x A. johnstonii Oliv. ex Hell., commonly known as Elgon Lady’s Mantle, is a herbaceous perennial that is propagated mainly through division and seed.
Division
Division is the most common method used to propagate Alchemilla elgonensis. This method involves separating the plant into smaller sections, each with its own roots and stems. The ideal time for division is in early spring when the plant is still dormant or in fall. Care should be taken not to damage the roots and stems during division. Each division should have at least two shoots with new roots. The new sections should be replanted immediately in a location with similar growing conditions as the original plant.
Seed Propagation
Alchemilla elgonensis can also be propagated through seed, although it is not as reliable as division. Seed should be sown in the autumn or spring in a well-draining soil mix, either indoors or outdoors. The seeds should be covered with a light layer of soil and kept moist. Germination usually occurs within two to three weeks, but it can take longer. Once the seedlings are big enough to handle, they should be transplanted into individual pots and kept in a greenhouse or protected area until they are strong enough to plant outdoors.
