Cultivation methods for Dimorphotheca tragus DC.
Dimorphotheca tragus DC., commonly referred to as Cape marigold, is a beautiful annual or perennial plant with an erect growth habit, reaching a height of 10-60 cm. This plant prefers well-drained soil with full sun exposure.
The best way to grow Cape marigold is to sow seeds indoors in early spring, and then transplant them outside when the danger of frost is passed. Alternatively, sow the seeds directly into a well-prepared garden bed after the danger of frost has passed. In areas with hot summers, it is best to plant the seedlings in a partially shaded area to prevent them from wilting under the sun's direct heat.
Watering needs for Dimorphotheca tragus DC.
Dimorphotheca tragus DC. needs moderate watering. Overwatering can lead to root rot, so ensure that the soil is well-drained. The best watering practice is to allow the top layer of soil to dry out before watering again.
During the hot summer months, Cape marigold needs to be watered more frequently. Water the plants early in the morning or late in the evening to prevent the leaves from getting scorched by the sun.
Fertilization for Dimorphotheca tragus DC.
Cape marigold is not a heavy feeder and does well with general-purpose fertilizer. You only need to fertilize the plants once every three weeks during the growing season. Avoid over-fertilizing as it can lead to excessive foliage growth and poor flowering.
When applying fertilizer, ensure that you do not allow it to touch the leaves or stem, as it can cause damage to the plant. Water the plant immediately after applying fertilizer to prevent burn.
Pruning for Dimorphotheca tragus DC.
Cape marigold does not require much pruning. Deadheading the plant by removing spent blooms will promote further blooming. However, avoid pruning more than a third of the plant at any given time, as this can lead to stunted growth or even kill the plant.
Cape marigold also benefits from occasional pinching to remove leggy or weak growth and promote bushier growth.
Propagation methods for Dimorphotheca tragus DC:
Dimorphotheca tragus DC. can be propagated by seeds, cuttings, and division.
Propagation by seeds:
Seeds should be sown in well-draining soil and kept moist until germination. Germination can take up to two weeks.
It is recommended to start seeds indoors in the early spring and then transplant them outdoors when the danger of frost has passed.
Propagation by cuttings:
Softwood or semi-hardwood cuttings can be taken from the plant in the early summer.
The cuttings should be about 4-6 inches in length, and the bottom leaves should be removed. The cuttings should be dipped in rooting hormone and placed in well-draining soil.
Keep the cuttings moist and in a warm, bright location. Rooting should occur within 4-6 weeks.
Propagation by division:
This plant can also be propagated by division in the spring or fall.
To divide the plant, carefully dig it up and separate the root ball into multiple sections. Each section should have a good amount of foliage and roots.
Replant the sections in well-draining soil and keep them well-watered until established.
