It is sensitive to sudden changes in temperature and should be placed in an area where the temperature is relatively stable.
Soil Requirements
Cyrtandra ×subintegra St. John prefers a well-draining soil that is rich in organic matter. A slightly acidic soil with a pH level between 6.0 and 7.0 is ideal for this plant. It also requires good water retention, as it does not tolerate drought or waterlogging. Adding perlite or sand to the soil can help improve drainage and prevent the soil from becoming too compact.
Cultivation methods
Cyrtandra ×subintegra is a tropical evergreen plant that thrives in warm, humid environments and can be grown indoors or outdoors. To cultivate this plant, select a location with bright, indirect sunlight and consistent temperatures between 70-85°F. Plant it in well-draining soil that is rich in organic matter, as the plant requires good drainage for optimal growth.
Watering needs
As a tropical plant, Cyrtandra ×subintegra loves moisture, and it needs to have consistently moist soil. Water your plant whenever the first inch of soil feels dry. During the growing season, which typically runs from spring to summer, increase your frequency of watering and make sure your plant isn't sitting in standing water.
Fertilization
During the growing season, you should fertilize your Cyrtandra ×subintegra once every two weeks with a balanced, water-soluble fertilizer. Be careful not to overfertilize, which can damage the plant and lead to root rot. In the winter, the plant's growth will slow down, so you can reduce the frequency of fertilizing.
Pruning
Cyrtandra ×subintegra benefits from periodic pruning to keep its size in check and promote healthy growth. Prune your plant in the spring before its growing season begins, and use clean, sharp shears to make the cuts.

Propagation of Cyrtandra ×subintegra St. John
Cyrtandra ×subintegra St. John can be propagated through various methods, including:
Seed Propagation
The plant can be propagated by seeds that are obtained from the ripe fruit. The seeds should be sown in a mixture of sand and peat and kept in a warm and moist environment.

Stem Cuttings
Stem cuttings can be taken from softwood stems or terminal growth. A rooting hormone can be applied at the cut end of the stem, and the stem inserted into a well-draining potting mix. The container should be covered with a plastic bag to create a humid environment to encourage root formation. Once roots have developed, the new plants can be transplanted into individual containers or directly to the ground.
Division of Clumps
Cyrtandra ×subintegra St. John can also be propagated through division of clumps. This method involves separating the plant's roots and foliage into smaller sections and planting them separately. The plant should be watered well in the days leading up to division to reduce shock.
Propagation of Cyrtandra ×subintegra St. John can be an enjoyable task for gardeners looking to increase their collection. With the appropriate application of the methods discussed, one can expand their garden in not time.
