Cultivation methods
Diascia vigilis Hilliard & B.L.Burtt is a small perennial plant that is commonly grown as an annual in gardens. It usually grows up to 6 inches tall and spreads up to 12 inches wide. This plant is native to South Africa and grows well in full sun to partial shade locations. It prefers well-drained soil rich in organic matter and stays moist.
You can start the plant indoors in late winter or early spring, depending on your climate. Sow the seeds onto moist soil and cover them lightly with soil. Place the container in a warm location or use heat mats to encourage germination. Once they reach a few inches tall, transplant them outside in spring when there's no frost in the soil. Alternatively, you can buy young plants from a nursery and plant them directly outside in the garden.
Watering needs
Diascia vigilis Hilliard & B.L.Burtt needs regular watering to thrive. However, it is crucial to avoid overwatering the plant, which can lead to root rot and other problems. Water the plant deeply once a week, especially in hot and dry weather. Ensure the soil drains well and doesn't stay wet all the time. You can also mulch around the plant to help retain moisture in the soil.
Fertilization
Diascia vigilis Hilliard & B.L.Burtt benefits from regular fertilization throughout the growing season to promote healthy growth and blooming. Use a balanced fertilizer with an N-P-K ratio of 10-10-10 or a slow-release fertilizer once every four weeks.

Pruning
Diascia vigilis Hilliard & B.L.Burtt has a mounding habit and requires occasional trimming to keep its shape and promote bushier growth. You can pinch back the tips of the stems when the plant reaches 4-6 inches tall. This will encourage branching and more flowers. Deadhead the faded blooms regularly to stimulate continuous blooming. Cut back the entire plant by one-third in midsummer to encourage fresh growth and more abundant blooming.
Propagation of Diascia vigilis Hilliard & B.L.Burtt
Diascia vigilis Hilliard & B.L.Burtt can be propagated by seeds, cuttings, or division. Each method has its own advantages and disadvantages, and the appropriate method can depend on the availability of materials, time, and resources.
Propagation by Seeds
Propagation by seeds involves sowing the seeds in a seed tray or potting mix. The seeds should be covered lightly with soil and kept moist until germination. Germination can take up to two weeks, and the seedlings can be transplanted into individual pots or planting beds once they have grown to a suitable size.
Propagation by Cuttings
Propagation by cuttings involves taking stem cuttings from the plant and rooting them in a soilless mix. The ideal time to take cuttings is in the spring or fall. The cuttings should be dipped in rooting hormone and inserted into the soilless mix. It is important to keep the soil moist and humid during rooting, and the cuttings can be transplanted into individual pots or planting beds once roots have developed.
Propagation by Division
Propagation by division involves dividing the plant into smaller sections, each with its own roots and foliage. This method is best performed in the fall or early spring. The plant should be dug up carefully, and the root ball should be divided into several sections. Each section should be replanted in its own pot or planting bed with fresh soil and watered regularly until established.
