Monarch of the Veldt problems — and how to fix them
Monarch of the Veldt (Arctotis fastuosa) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Poor flowering in summer heat
Arctotis fastuosa is a cool-season bloomer and stops flowering when temperatures consistently exceed 28–30°C. In hot climates, sow in autumn for a spring display rather than planting for summer colour.
Root and stem rot from overwatering
Plants in heavy or moisture-retaining soils rapidly develop root rot, causing stem collapse at soil level. Always grow in sharply drained media and water only when the upper soil is dry.
