Temperature Requirements
The plant prefers warm temperatures ranging from 20-30°C (68-86°F). It can tolerate slightly cooler temperatures down to 15°C (59°F) but may experience stunted growth or leaf drop. Hermannia patellicalyx does not tolerate frost or freezing temperatures, and it is necessary to bring the plant indoors during winter in regions with cold temperatures.
Soil Requirements
Hermannia patellicalyx grows best in well-draining soil with a slightly acidic to neutral pH level between 6.0-7.0. The soil should be rich in organic matter and nutrients. The plant prefers loose soil that allows for proper air circulation and water drainage. Adding compost or peat moss to the soil can improve the nutrient content and water retention capacity.
Cultivation Methods
Hermannia patellicalyx Engl. is an easy-to-grow plant that thrives in warm temperatures, so it is best grown in a warm climate. To grow this plant, you need to choose a location with well-draining soil, preferably sandy and slightly acidic. You can propagate your plant from seeds or cuttings. However, cuttings root easily and are more preferable. Plant your cuttings in the soil about 2cm deep, ensuring the soil is moist but not wet. Make sure you plant the cutting in a spot with bright but indirect sunlight.
Watering Needs
Well-draining soil is essential for the successful growth of Hermannia patellicalyx Engl. Ensure that the soil is moist, but not waterlogged continually. You can reduce watering in winter and increase it in the summer season. As the plant develops, increase the amount of water in moderation. It is advisable to avoid waterlogging the soil as it can lead to root rot.
Fertilization
It is essential to fertilize the soil to promote the healthy growth of your Hermannia patellicalyx Engl. Use a fertilizer with a balanced ratio of nitrogen, potassium and phosphorus. Apply it every two weeks during the growing season, which is from spring to summer. The fertilization of the plant should be reduced as winter approaches. Do not over fertilizer the soil as it can lead to yellowing of leaves and hinder growth.
Pruning
Pruning is not necessary for Hermannia patellicalyx Engl., but it can stimulate new growth. Use pruning shears to cut back drain branches or stems. This plant blooms mostly in the growing season, and pruning can tidy the plant when the flowering is done.
Propagation of Hermannia patellicalyx Engl.
Hermannia patellicalyx Engl., commonly known as the Vygies or Hermannia, is a beautiful, evergreen shrub with attractive, shiny green foliage and delicate, pink, and white flowers. Propagation of Hermannia patellicalyx is relatively easy and can be done by three primary methods; propagation using seeds, stem cuttings and layering.
Propagation by seeds
Propagation by seeds is relatively easy, and the best time to sow the seeds is during spring or summer when temperatures are warm. Sow the seeds in a well-drained seed compost, covering them with a thin layer of soil.
Water the seeds regularly and keep the soil moderately moist. The seeds should germinate after two to four weeks. Once the seedlings have grown to a size where they can safely be handled, transplant them into individual pots or directly into the ground.
Propagation by stem cuttings
Hermannia patellicalyx can also be propagated by stem cuttings, taken during spring or summer when the plant is actively growing. Take 10-15 cm long, semi-hardwood stem cuttings, making sure each cutting has at least two nodes. Remove all leaves from the bottom half of the cutting and dip the cut end into rooting hormone powder.
Insert the cutting into well-drained potting soil and keep the soil slightly moist. Cover the cutting with a plastic bag or container to create a humid environment, which will help it root. After three to four weeks, remove the cover and check for roots. Once the cutting has roots, transplant it into an individual pot, using well-drained potting soil.
Propagation by layering
Propagation by layering involves inducing the plant to grow roots along the stem while it is still attached to the parent plant. This method is best done during spring or summer. Select a healthy, flexible stem and make a small incision at the bottom of the stem. Dust the incision with rooting hormone, and then bury it in a shallow hole in the soil mix.
Cover the stem with soil and keep the soil moderately moist. After several weeks, roots should have grown from the stem's incision. Carefully cut the stem from the parent plant, transplant it into an individual pot and monitor for growth.
Propagation of Hermannia patellicalyx is relatively easy and can be done throughout the year, but it is always best to propagate the plant during the growing season and using healthy plant material. No matter which method you choose, be sure to use well-draining potting mix, maintain adequate moisture, and keep the plant in a bright but protected area as it continues to develop and mature.
