The plant requires regular fertilization to promote healthy growth and flowering. Use a slow-release granular fertilizer that is formulated for acidic-loving plants, particularly during the growing season. Follow the recommended dosage instructions on the fertilizer packaging for best results.
Pruning Ternstroemia stahlii Krug & Urban
Pruning is not necessary for the Stahl's camellia, but it can be done to shape the plant or remove any dead, damaged, or diseased branches. The best time to prune is immediately after the flowering season. Always use clean, sharp pruning shears and disinfect them after each use to prevent the spread of disease.
Propagation of Ternstroemia stahlii Krug & Urban
Ternstroemia stahlii Krug & Urban, also known as the Puerto Rico mountain-primrose, is a tropical evergreen shrub that belongs to the Pentaphyllaceae family. Propagating this plant is essential for maintaining and preserving its unique genetic traits. There are two methods of propagating Ternstroemia stahlii Krug & Urban: seed propagation and vegetative propagation.
Seed propagation
Seed propagation is a popular method of propagating Ternstroemia stahlii Krug & Urban. The seeds of this plant are small, black, and flat, and they are produced in abundance. Seed propagation requires careful handling of the seeds to ensure successful germination.
The first step in seed propagation is collecting fresh ripe seeds in the fall. The seeds can be extracted from the fruit by soaking them in water and removing the fleshy pulp. The seeds should then be dried, and the wings should be removed, leaving only the small, black seeds.
The seeds of Ternstroemia stahlii Krug & Urban require stratification, which is a period of cold and moist conditions necessary for breaking dormancy and promoting germination. The seeds can be stratified in plastic bags in the refrigerator for several months. Once stratification is complete, the seeds can be sown in a well-draining soil mixture and kept moist until germination occurs.
Vegetative propagation
Vegetative propagation is another method of propagating Ternstroemia stahlii Krug & Urban. This method involves taking cuttings from the mother plant and rooting them in a suitable rooting medium.
The best time to take cuttings is in the spring or early summer when the plant is actively growing. Select healthy, disease-free stems that are about 4-6 inches long and have at least two sets of leaves. Remove the lower set of leaves and dip the cut end of the stem in a rooting hormone powder.
Plant the cutting in a rooting medium made of a mixture of perlite and peat moss. Keep the cutting in a warm, humid environment and mist it regularly. In about four to six weeks, the cutting should have rooted, and it can be transplanted into a pot or the ground.
By using the two methods mentioned above, gardeners and horticulturists can propagate Ternstroemia stahlii Krug & Urban with ease and maintain the unique characteristics of this tropical evergreen shrub.

To manage scale insects, prune heavily infested areas and apply insecticidal soap or horticultural oil to the plant, covering all the affected areas.
Spider Mites
Spider mites are tiny pests that suck the sap from the leaves of Ternstroemia stahlii Krug & Urban, causing them to turn yellow and become dry and brittle. To manage spider mites, rinse the leaves with a forceful spray of water, making sure to target the undersides of the leaves. Apply insecticidal soap or horticultural oil if necessary.
Overall, the key to preventing diseases and pests in Ternstroemia stahlii Krug & Urban is to maintain good garden hygiene by keeping the plant well-watered, fertilized, and pruned.
