The plant can be propagated by dividing the root ball during the spring or fall. It is important to make sure that each division has at least two or three healthy shoots. The plant can also be grown from seed, which should be sown during the fall, in the same area where the plant will be planted. The seeds should be sown on the surface of the soil or lightly covered with soil.
Watering Needs
Alchemilla cryptantha Steud. ex A.Rich. prefers to be grown in well-drained soil and does not require much water. The plant should be watered deeply but infrequently.

Deadheading the spent blooms can also help to promote additional blooms. It is important to remove any diseased or damaged leaves or stems promptly to prevent the spread of disease.
Propagation of Alchemilla cryptantha Steud. ex A.Rich.
Alchemilla cryptantha Steud. ex A.Rich., commonly known as "starflower lady's mantle," is a perennial succulent plant native to South Africa. This plant is widely praised for its unique appearance and attractive flowers. There are numerous propagation methods for Alchemilla cryptantha Steud. ex A.Rich., and each has its own advantages and disadvantages. In this article, we will discuss some of the most common propagation methods for Alchemilla cryptantha Steud. ex A.Rich.
Seed Propagation
One of the most common methods of propagating Alchemilla cryptantha Steud. ex A.Rich. is through seed propagation. Collect the seeds after the flowering season and before the plant goes dormant for the winter. Plant the seeds in a pot containing a well-draining soil mix. Cover the seeds lightly with the soil and water gently. Next, place the pot in a warm, bright area and maintain a consistent moisture level until the seedlings emerge. Once the seedlings have grown large enough, transfer them to larger pots or into the garden.
Division
Division is another popular propagation method for Alchemilla cryptantha Steud. ex A.Rich.. This method involves dividing the plant into smaller clumps, which then become individual plants. Wait until spring to divide the plant when new growth is just beginning. Carefully dig up the plant and separate the clumps. Make sure that each new clump has some roots and leaves before transplanting it to a new location. Keep the soil moist for the first few weeks until the plant is established.
Cuttings Propagation
Cutting propagation is another method of propagating Alchemilla cryptantha Steud. ex A.Rich.. In this method, cut a healthy stem from the mother plant, making sure it is at least 10-15 cm long. Next, remove all the leaves from the lower half of the cutting, except for one or two at the top. Dip the cut end of the stem into rooting hormone powder and insert it into a pot containing a well-draining soil mix. Water gently, and cover the pot with a plastic bag to maintain high humidity levels. After a few weeks, the cutting should develop roots and new growth and can then be transplanted to a larger pot or into the garden.
These are just a few of the many methods of propagating Alchemilla cryptantha Steud. ex A.Rich.. By choosing the propagation method that works best for you, you can easily multiply your stock of starflower lady's mantle plants.

Pest Management for Alchemilla cryptantha Steud. ex A.Rich.
Alchemilla cryptantha Steud. ex A.Rich. is also susceptible to certain pests that can hinder their growth and development. The most common pests affecting this plant are aphids and spider mites.
Aphids are small, soft-bodied insects that suck the sap from the leaves and stems of the plant, causing wilting and stunting of growth. To manage aphids, use insecticidal soap or neem oil. Introducing beneficial insects such as ladybugs, lacewings, and parasitic wasps can also help control aphid populations naturally.
Spider mites are tiny arachnids that feed on the plant cells, causing discoloration and damage. They are often found on the undersides of the leaves. To manage spider mites, use insecticidal soap or neem oil. Regularly spraying the plant with water can also help control spider mite populations naturally.
