The plant cannot tolerate high temperatures above 26°C (80°F), especially when the air is dry, which can lead to the death of the plant. During winter, the plant should be moved indoors or kept in a greenhouse to protect it from frost.
Soil Requirements
The Diascia engleri Diels plant grows best in well-draining soils that are rich in organic matter. The soil should be slightly acidic with a pH range of 6.2 to 6.8. A good potting mix for the Diascia engleri Diels plant should consist of peat moss, perlite, and vermiculite. The plant prefers soils that are moist but not waterlogged to prevent root rot. It is important to ensure proper drainage, especially when planting the Diascia engleri Diels in containers or hanging baskets.
Cultivation methods
Diascia engleri Diels, commonly known as Twinspur, is a charming flowering plant native to South Africa. It can be grown outdoors in a garden or as a houseplant, according to your preference. For outdoor planting, select a location that gets plenty of sunlight, at least six hours per day, and has well-draining soil. It's preferable to plant Diascia engleri during the springtime when the soil temperatures have risen to about 60°F. The plant prefers moderate temperatures ranging from 60°F to 70°F to grow well.
Watering needs
While watering Diascia engleri, focus primarily on maintaining consistent, even, and adequate soil moisture. The plant prefers damp soil but can't withstand standing water and soggy soil, so avoid over-watering. During its growing period, water your Diascia plant every 3 to 4 days, or more often if the weather is hot and dry. In winter, reduce the watering as the plant's growth slows down considerably. Use a well-draining soil mix, such as a 50-50 blend of garden soil and perlite for potting the plant.
Fertilization
Twinspur plants are light feeders and require minimal fertilization. During the growing season, fertilize your Diascia engleri with half-strength balanced fertilizer every two weeks. Avoid overfertilizing as it can lead to stunted growth and weakened plants that are vulnerable to pest attacks. Furthermore, if using a slow-release fertilizer, it's best to apply it twice a year, at the beginning of the growing season and again mid-way through the summer.
Pruning
While Diascia engleri does not need regular pruning, cutting the dead blooms off can encourage flowering. Additionally, Pruning after the last frost helps to rejuvenate the plant and promote bushier and fuller growth. Using pruning shears or scissors to make a slanted cut as close to the base of the stem as possible.
Propagation of Diascia engleri Diels
Diascia engleri Diels is an attractive and floriferous plant that is commonly propagated through various vegetative methods.
Softwood Cuttings
Softwood cuttings are one of the most popular methods of propagating Diascia engleri Diels. This method involves taking cuttings from young, green stems of the plant. The cuttings should be approximately 5-10 cm long and should be taken during the growing season. The leaves on the lower part of the cutting should be removed, and the stem should be dipped in rooting hormone before being inserted into a pot filled with moist potting soil. Ideal temperatures for rooting range from 18-24°C, and the cutting should be kept in a warm, bright location.
Division
Diascia engleri Diels can also be propagated through division. This method involves dividing a mature plant into several individual sections, each containing its own root system. It is best to divide the plant during the early spring while it is still dormant and before the new growing season has begun. The divided sections can then be potted up individually and grown on.
Seeds
Propagation using seeds is also possible but is not commonly used with Diascia engleri Diels. Sow the seeds in a well-draining soil mixture, cover the seeds gently with soil, and water gently. The seeds should be kept moist and warm until germination occurs, which typically takes several weeks. The seedlings can then be gradually hardened off before planting outdoors.
Overall, Diascia engleri Diels is a relatively easy plant to propagate through various vegetative methods, and growers can use the method that works best for them.
