When to Plant Summer Bulbs in South Africa

Western Cape & coastal frost-free areas: Late August to October, once soils warm and the risk of cold snaps is low.

Highveld & frost areas: September to November, after the last frost.

Lowveld / very warm zones: From mid to late August, with afternoon shade and steady moisture where needed.

Succession tip: Stagger plantings, especially
Gladiolus,
every 2–3 weeks for continuous flowers into autumn.

For dahlias specifically, timing is very important. Read our guide:

Planting Basics for Summer Bulbs

Light: Most summer bulbs prefer full sun, around 6–8 hours per day. Use light afternoon shade in very hot areas.

Soil: Plant into free-draining soil with added compost. Avoid heavy, waterlogged soil.

Depth: As a rule of thumb, plant bulbs around 2–3 times their height. Dahlia tubers are planted more shallowly, with the growing eye covered by about 3–5 cm of soil.

Water: Water in after planting, then keep evenly moist once active growth starts. Avoid overwatering dormant tubers.

Feed: Use a potassium-rich flower fertiliser during bud and bloom for stronger colour and better flowering.

Support: Taller dahlias, gladiolus and lilies may need staking, especially in windy gardens.
