Temperature Requirements
The ideal temperature range for the Calvoa stenophylla Jacq.-Fél. plant is between 60-70°F (15-21°C). It is important to protect the plant from extreme temperature fluctuations as it is sensitive to both hot and cold temperatures.
Soil Requirements
The Calvoa stenophylla Jacq.-Fél. plant prefers a well-aerated, well-draining soil mix. The soil should be slightly acidic with a pH range of 5.5-6.5. It is recommended to mix perlite or sand into the soil to improve the drainage.
Cultivation
Calvoa stenophylla, also known as the necklace vine, is a tropical plant that thrives in warm temperatures and high humidity. To cultivate this plant, choose a spot in your home that receives bright, indirect light and maintains a consistent temperature between 65-85°F.
Use well-draining soil, and plant Calvoa stenophylla in a pot that allows for good air circulation. You can propagate this plant through stem cuttings and grow it in hanging baskets or on a moss pole.
Watering Needs
Calvoa stenophylla needs regular watering to thrive. Keep the soil evenly moist, but not soggy, throughout the growing season, and reduce watering in the winter when the plant is in a dormant state.
Be careful not to let the plant sit in standing water, as this can lead to root rot. Instead, allow excess water to drain from the bottom of the pot and empty the drainage tray.
Fertilization
During the growing season, fertilize your Calvoa stenophylla plant every two weeks with a balanced, water-soluble fertilizer. Make sure to follow the instructions on the label and avoid over-fertilization, which can cause damage to the roots.
Reduce fertilization during the winter dormant period, and resume regular applications when new growth appears in the spring.
Pruning
To keep your Calvoa stenophylla plant looking its best, prune it regularly throughout the growing season. Pinch back the tips of the stems to encourage bushier growth, and trim any stems that have grown too long or are starting to look leggy.
You can also trim away any yellow or damaged leaves as they appear. Avoid pruning during the winter dormant period, as this can cause stress to the plant.
Propagation of Calvoa stenophylla Jacq.-Fél.
Calvoa stenophylla Jacq.-Fél., commonly known as the Narrow-Leaf Calvoa, can be propagated through both vegetative and sexual methods.
Vegetative Propagation
The most common method of vegetative propagation is by stem cuttings. Cuttings should be taken from healthy and disease-free plants in the months of June to August. The cuttings should have 2-3 nodes and a length of 8-12 cm. The base of the cutting should be treated with a rooting hormone and planted in a well-draining potting mix. The pot should be covered with a plastic bag or a propagator lid to maintain the humidity and warmth. Roots are expected to appear within 4-5 weeks, and the plant can be transplanted into a bigger pot after 2-3 months.
Sexual Propagation
Sexual propagation involves the use of seeds. The seeds should be collected from ripe fruits. The fruit should be stored in a container for a few days, allowing it to ripen fully. The seeds should then be separated from the fruit and washed to remove any remaining pulp. The seeds can be sown in a well-draining potting mix, then covered with a thin layer of sand. The pot should be watered thoroughly, and covered to maintain humidity. The seeds will germinate in 3-4 weeks, and the seedlings can be transplanted into individual pots after 2-3 months.
