This mesemb is relatively hardy, tolerating mild frost (-2°C).  It tolerates dry, hot summer temperatures of 40°C and above. It can be grown successfully in most gardens in the Western Cape and in other parts of South Africa, but not in areas of high summer rainfall and in subtropical areas.

Drosanthemum striatum is cultivated mostly from seed. Copious amounts of seed are produced after flowering, normally around late January. Seeds are light brown and each seed is about the size of a pin head.

Seed should be sown in late autumn (May). Sow the seeds in open, flat seed pans using a well drained loamy soil mixture. Ensure that seeds are not sown too thickly otherwise they may damp off (rot) when they germinate. Firm the seeds down with a piece of flat board and cover the seeds with a layer of sieved river sand.

Keep the seed pans in a well-ventilated area where there is good light. Water with a fine spray-head. If conditions are warm and windy, it may be necessary to water on a daily basis. Water earlier in the day than than the end of the day. The reason for this is that humidity increases as nightfall approaches thus increasing the risk of damping off.

When the seedlings are 50 mm or higher, transplant them either into half-litre plastic bags or small plastic containers. Keep them in a semi-protected location at first until they are sufficiently hardened off. They may then be moved outside. It is recommended that they have at least three weeks to harden off completely.

To grow from cuttings treat the material with a rooting hormone prior to striking in a growing medium. Ideal rooting mediums are essentially 50% washed, sieved river sand, 25% perlite and 25% vermiculite. Good drainage is the key to good rooting.

The ideal time to root these cuttings would be in May or June (southern hemisphere). Once roots have formed, normally from the nodes (where buds come from), transplant into light loamy soils, harden off for three weeks and move to an outside location prior to planting.
