Cultivation
The Rosa anatonensis St. John plant thrives in well-drained soil with a pH range of 6.0 to 7.0. It prefers full sunlight but can tolerate partial shade. The plant can be propagated through seeds or cuttings. If using seeds, start them indoors in late winter and transplant outdoors in the spring. Cuttings should be taken in early summer, dipped in rooting hormone, and planted in a well-draining soil mix.
Watering Needs
Rosa anatonensis St. John plants require consistent watering to establish a healthy root system, especially during the first year. Water once a week, aiming for about an inch of water per week. During times of drought, increase water to twice a week.
Fertilization
Fertilize Rosa anatonensis St. John plants in the spring and summer. Use a balanced fertilizer with a NPK formula of 10-10-10, applying according to the package instructions. Avoid fertilizing in the fall to allow the plant to prepare for winter dormancy.
Pruning
Rosa anatonensis St. John plants require regular pruning to maintain their shape and promote new growth. Prune once a year in late winter or early spring, removing any dead or diseased wood. Cut back any branches that cross over others or grow inward. Aim to thin the center of the plant to provide airflow and sunlight to the leaves. For a tidy appearance, lightly trim back the tips of the branches.
Propagation of Rosa anatonensis St. John
Rosa anatonensis St. John, commonly known as the clifftop rose, is a rare species of rose that is primarily found on the rocky cliffs of Oahu, Hawaii. Due to its rarity and unique beauty, people often want to propagate this plant for their gardens. There are several methods of propagation that can be used for Rosa anatonensis St. John.
Seed Propagation
The most common method of propagation for Rosa anatonensis St. John is through seeds. Seeds can be collected from the ripe fruits by cutting them open and removing the seeds. The seeds should then be cleaned and dried before sowing them directly into the soil or starting them indoors under grow lights. The ideal time for sowing is in the spring, but it can be done throughout the year.
Cuttings Propagation
Another method of propagation for Rosa anatonensis St. John is through cuttings. Softwood cuttings are taken from young stems in the spring or summer. The cuttings should be about 4-6 inches long and have at least two nodes. Remove the leaves from the lower half of the cutting and dip it in rooting hormone. The cutting should be planted in a mixture of sterile soil and sand and kept in a warm, humid environment until it develops roots.
Layering Propagation
Layering is another propagation method that can be used for Rosa anatonensis St. John. Select a healthy branch and make a small wound where the branch touches the soil. Cover the wound with soil and secure it in place with a stone or wire. Keep the soil moist and wait for roots to develop. Once roots have developed, cut the branch from the parent plant and transplant it to its own pot or in the ground.
Propagation of Rosa anatonensis St. John can be tricky, but with patience and persistence, successful propagation can be achieved using one of these methods.
Disease and Pest Management for Rosa anatonensis St. John Plant
Rosa anatonensis St. John, also known as the Molokai rose, is a species of wild rose that is found only in Hawaii. Just like any other plant, it is susceptible to several diseases and pests. Proper disease and pest management is essential to keep the plant healthy and thriving.

Another disease to watch out for is black spot. Black spot is a fungal disease that causes black spots to appear on the leaves of the plant, which can lead to defoliation if left untreated.
Disease Management
To manage fungal diseases, prune and dispose of any infected plant parts that you find. Treat the plants with a fungicide spray that is labeled for Rose plants, making sure to follow the instructions on the label. A preventive measure is to provide adequate air circulation and avoid overhead watering that can create a humid environment. Watering at the base of the plant and irrigating early in the day are good measures to prevent infection.

Pest Management
Managing pest infestations involves both chemical and non-chemical practices. You can use insecticidal soap or neem oil spray on your plants to reduce the spider mite population. Spider mites can also be controlled by regular pruning, damping off leaves, and increasing the humidity around the plant. Thrips can be kept under control by spraying the plants with insecticidal soap or neem oil or introducing beneficial insects such as lacewings or ladybugs.
By managing diseases and pests, you can keep your Rosa anatonensis St. John healthy and thriving for years to come.
