What to Plant in November in South Africa: Flowers, Bulbs & Vegetables
November brings warmer soil, longer days and faster growth across most of South Africa. Summer planting is already well under way, but there is still plenty to sow and plant for colour, vegetables and cut flowers through midsummer and into autumn.
The main November priorities are heat management, steady watering and succession planting. In very hot regions, protect young plants from harsh afternoon sun while their roots establish, and avoid planting into dry soil during the hottest part of the day.
Flowers to Sow in November
Warm-season annuals remain excellent choices for November sowing. Quick growers can still establish fast and flower well during summer.
- Zinnias: fast colour and one of the best annuals for cutting.
- Cosmos: easy to direct sow in sunny beds.
- Sunflowers: continue sowing in batches for staggered flowering.
- Marigolds: reliable bedding colour through hot weather.
- Celosia: thrives in warmth and gives strong colour and texture.
- Gomphrena: a useful heat-tolerant option for sunny gardens.

Can I Still Plant Summer Bulbs in November?
Yes. November is still a useful planting month for many summer-flowering bulbs, corms and tubers, particularly where frost delayed spring planting. The trade-off is that later plantings may flower later and need more careful watering during establishment.
- Dahlias – still a good option where there is enough warm growing season ahead.
- Gladioli – continue succession planting for later flower spikes.
- Zantedeschia / Calla Lilies – establish well with consistent moisture and good drainage.
- Amaryllis – suited to pots and garden positions with excellent drainage.

Vegetables to Plant in November
November suits beans, cucumbers, squash, pumpkins, sweetcorn, tomatoes, peppers and chillies in most warm areas. Beetroot, carrots and leafy greens can also be planted, but in very hot gardens they benefit from reliable moisture and some protection from extreme afternoon heat.
Keep succession sowing going. Beans, sweetcorn and cucumbers can be sown in smaller batches rather than one large planting, giving you a longer and more manageable harvest.
Herbs for November
Basil enjoys the warmer conditions of November and can grow rapidly with regular harvesting. Chives, thyme, oregano and parsley remain useful choices. Coriander and rocket can become short-lived in heat, so sow small batches and choose a cooler position if you want to keep them productive for longer.
November Planting by Region
Western Cape
By November, dry summer conditions are usually becoming more established. New plantings need consistent irrigation and mulch. Plant early in the morning or later in the afternoon to reduce transplant stress. Moisture-loving plants such as Hydrangeas need particular attention as temperatures rise.
Highveld
Summer rainfall and storms support rapid growth, but heavy downpours can damage young seedlings and compact bare soil. Mulch beds, stake tall plants and make sure drainage is good around bulbs and tubers.
KwaZulu-Natal Coast and Lowveld
Heat and humidity can be intense. Water deeply rather than keeping the surface constantly wet, and maintain airflow around dense plants. Afternoon shade can help newly established seedlings during very hot spells.
November Garden To-Do List
- Check irrigation more frequently as temperatures rise.
- Mulch exposed soil to reduce moisture loss.
- Continue staking dahlias, gladioli and tall summer flowers.
- Deadhead annuals to extend flowering.
- Succession sow sunflowers, beans, sweetcorn and quick annual flowers.
- Inspect foliage regularly for caterpillars, aphids and fungal problems.
- Harvest herbs and vegetables frequently to encourage continued production.
Is November Too Late to Start a Summer Garden?
No. November can still produce an excellent summer garden, especially with fast-growing flowers, vegetables and later-planted bulbs. Focus on plants that establish quickly and be realistic about your local heat and rainfall. In very hot regions, good irrigation and mulch can matter more than planting a week earlier.
November Planting FAQs
Can I plant dahlias in November?
In many South African regions, yes. Planting may be later than ideal in some areas, but warm conditions can still support strong growth if water and growing time are adequate.
Can I still plant gladioli in November?
Yes. Gladioli are particularly useful for succession planting. Later batches extend the flowering and cutting season.
What flowers are quick enough to sow in November?
Zinnias, cosmos, sunflowers, marigolds, celosia and gomphrena are practical warm-season choices where conditions are suitable.
