Dimorphotheca cuneata occurs primarily in the winter-rainfall areas, but can be cultivated successfully in the summer-rainfall areas of South Africa.

Seeds germinate easily and mature one month after flowering. Seeds need to be gathered as soon as possible otherwise they will soon be lost to the elements, especially wind. Seeds are relatively large and flat, 10-12 mm in length and 8-10 mm in breadth. They are pale brown in colour. Sow the seeds in a seed pan during the cool autumn months (April to mid June in the southern hemisphere). Ensure that there is adequate drainage in the bottom of the seed pan. If the seeds stand in too much water they will more than likely rot. The best medium to sow the seeds in is a sandy loam mixture. On top of this mixture, sprinkle a thin layer of coarse river sand, 5 mm deep. It is into this sand that the seeds are sown. Keep the area weed-free and water every second day. During very hot and dry weather water daily, preferably in the early morning when it is cool. Ensure, when watering, that the seeds are not blasted out of the soil; gentle watering is advised. Ensure that the seed trays are positioned in a sunny area. Seeds should be sown 4 mm below the soil surface. If sown too deep, they will be smothered and probably not germinate. Plant the seedlings out in September/October of the same year when they are approximately 50 mm in height. Under ideal conditions seedlings will grow rapidly.

Plants can also be cultivated from cuttings. Soft tip growth must be used. Strike cuttings in a mixture of 50% perlite and 50% sharp river sand. Ensure that the cutting medium is kept moist. Feed with a foliar organic feed. Strike cuttings when the plant is actively growing. April, May or June are the preferred months for striking cuttings. The strike rate is medium to high (about 75%). Ensure that the cuttings are misted well.

Dimorphotheca cuneata flourishes in well-drained, sandy loam soils. They can be cultivated in pots or planted in groups in the garden. Remember to plant them in a sunny locality, otherwise they will not flower properly.

A word of warning: great care must be taken not to plant this species in heavy clay soils.
