Light Requirements
The Tryphostemma scabrifolium Dandy plant requires bright, indirect light for optimal growth. It should be placed in a spot that receives bright light for at least 6 hours a day. However, direct sunlight should be avoided as it can cause damage to the leaves.
Temperature Requirements
The Tryphostemma scabrifolium Dandy plant grows well in warm temperatures and should be kept in an environment that ranges between 18ºC - 27ºC. It cannot tolerate extreme temperatures below 10ºC or above 35ºC. Therefore, it is important to maintain a constant temperature for the plant.
Soil Requirements
The Tryphostemma scabrifolium Dandy plant requires well-draining soil to grow properly. The soil should be rich in organic matter and have a pH level of 6 to 7.5. A mixture of peat moss, perlite, and sand can be an ideal soil mix for the plant. It is important to ensure that the soil does not become waterlogged, as this can cause root rot and other diseases. Therefore, it is best to water the plant only when the top layer of soil becomes dry.
Cultivation
Tryphostemma scabrifolium Dandy is a low-maintenance plant that is quite easy to grow. It can be propagated by seeds and stem cuttings. To propagate through seeds, plant the seeds in a well-drained potting mix, lightly covering them with soil. Seeds will germinate in about 3-4 weeks. To propagate through stem cuttings, select a healthy stem and cut a 6-inch piece just below a node. Remove the leaves from the bottom half and dip the cut end into rooting hormone. Plant the cutting in a well-drained soil mix and keep the soil slightly moist.
Watering Needs
The Tryphostemma scabrifolium Dandy plant prefers slightly moist potting mix, but it does not like to sit in water. Overwatering can cause the roots to rot, so it's essential to ensure proper drainage. Water the plant when the top layer of soil feels dry to the touch.
Fertilization
The Tryphostemma scabrifolium Dandy plant requires minimal fertilization. Fertilize the plant with a balanced liquid fertilizer once a month during the growing season, from spring to summer. Do not fertilize during the winter months, when the plant goes into dormancy.
Pruning
Pruning is not necessary for Tryphostemma scabrifolium Dandy. However, removing dead or damaged leaves and stems will not harm the plant and can make it look neater. Prune the plant in the spring or summer for best results.
Propagation of Tryphostemma scabrifolium Dandy
Tryphostemma scabrifolium Dandy, also known as the rough-leaved vine, is propagated through two main methods: seeds and stem cuttings.
Propagation by seeds
The seeds of Tryphostemma scabrifolium Dandy are sown during the spring season. Before sowing, the seeds are soaked in water for a few hours to soften the hard outer coat. The softened seeds are then sown in a mixture of well-draining soil and sand. The soil mixture should be kept moist but not waterlogged. Germination of the seeds takes place within a few weeks.
Propagation by stem cuttings
The stem cuttings of Tryphostemma scabrifolium Dandy can be taken during the summer season. The cuttings should be about 10 to 15 cm long and should have at least two nodes. The lower leaves of the cutting should be removed, and the cut end should be dipped in a rooting hormone powder. The cutting is then inserted into a mixture of well-draining soil and sand. The soil mixture should be kept moist but not waterlogged. The cutting will root within a few weeks and develop into a new plant.
Propagation of Tryphostemma scabrifolium Dandy through seeds and stem cuttings is relatively easy and can be done by both novice and experienced gardeners.
