Watering Needs
The plant requires regular watering during the growing season. Water should be applied deeply once or twice a week, depending on the weather and soil moisture. Avoid excessive watering, as this can lead to root rot and other problems. In the winter, reduce watering and allow the soil to dry out slightly between waterings.
Fertilization
Calystegia catesbiana Pursh ssp. sericata (House) Brummitt responds well to regular fertilization. Apply a balanced fertilizer every two to three weeks during the growing season. Apply organic fertilizer in the spring and fall to improve soil fertility. Avoid overfertilization, as this can lead to excessive vegetative growth and reduced flowering.
Pruning
Pruning can help maintain the shape and vigor of Calystegia catesbiana Pursh ssp. sericata (House) Brummitt. Prune the plant in the early spring before new growth begins. Remove any damaged or dead branches, and thin out any overcrowded areas. Prune the plant again after flowering to promote bushier growth and more flowers.
