This species grows easily from seed. The best time to sow is in autumn directly into the planting beds or first in seed trays or seedbeds from where the seedlings can be transplanted. Scatter the seed on well-prepared soil with good drainage and in full sun. The seeds can be lightly covered with sand or fine milled bark. Germination is fast, usually within 4 days. Watering the young seedlings regularly is important, as the young plants require plenty of water. The annuals respond very well to fertilizers but only apply fertilizers if the plants look stunted or deficient otherwise they grow too soft. The annuals transplant well and within 3-4 weeks after germination they usually a good size to handle. When planting, be generous with the annuals and plant quite closely, as a very full and rich effect is gained by close planting.

Many beautiful and interesting displays can be made by mixing the different annuals like the blue flax (Heliophila coronopifolia) which grows tall and thin, Felicia heterophylla a striking blue daisy and the brightly coloured Bokbaai vygies (Dorotheanthus bellidiformis). Bulbs like the arum lilies (Zantedeschia aethiopica) and watsonias grown in clumps work very well mixed with the annuals. At Kirstenbosch we collect all our own seed from the garden to be sown again the next year. If the seed is not collected Dimorphotheca pluvialis usually seeds itself the next year. Dimorphothecea pluvialis has no major pests at Kirstenbosch other than the guineafowls and Egyptian geese, which love to eat the soft new growth.
