Yellow, orange and striped New Day, Frosty Kiss and Big Kiss gazanias with green and silver foliage in a sunny South African garden

How to Grow Gazania from Seed in South Africa

Gazania is a sun-loving South African flower grown for bold, daisy-like colour in beds, edging, baskets and containers. This guide covers six exact Gardening.co.za Gazania rigens F1 seed products in three materially different groups: coated New Day, raw Frosty Kiss and larger raw Big Kiss. Use the module linked from your packet because seed form, plant size and finish time are not identical.

Quick Grow Facts

Botanical name: Gazania rigens; all six products are F1 ornamental lines grown as annuals.
Best method: sow one seed per cell in clean, fine, free-draining seedling mix. Tray sowing gives the best control of warmth and moisture.
Sow depth: about 1 mm or a thin vermiculite cover; do not surface sow exposed and do not bury deeply.
Germination light: optional for New Day and not required for Kiss or Big Kiss; provide bright light as soon as seedlings emerge.
Germination temperature: 21–22°C for New Day; 21–24°C for Frosty Kiss and Big Kiss.
Pretreatment: none. Do not soak, chill or scarify these current commercial seed forms.
Germination time: current packets allow 7–21 days. Breeder-controlled windows are 3–4 days from 50% to maximum germination for New Day and 4–6 days to radicle emergence for Kiss and Big Kiss.
Transplant stage: well-rooted plugs are normally ready in 4–5 weeks for New Day and 5–6 weeks for Frosty Kiss or Big Kiss.
Position: full sun after hardening off; flowers naturally close at night and may remain partly closed in cloudy weather.
Spacing: New Day 15–20 cm; Frosty Kiss about 20–25 cm; Big Kiss about 25–30 cm. The current local packets list 20 cm for all six.
Flowering: current packets say about 12 weeks. Breeder-controlled total crop time is about 12–14 weeks for New Day and 13–15 weeks for Frosty Kiss and Big Kiss.

New Day F1: Coated Seed and Compact Growth

Shop this module: New Day Tiger Mix, New Day Mix, New Day Bright Yellow and New Day Bright Orange.

New Day is Gazania rigens F1 coated seed. The plants form compact, sturdy mounds about 20–25 cm high and 15–20 cm wide, with shorter flower stems. Sow one intact coated seed per cell, cover about 1 mm or with a thin layer of coarse vermiculite, keep at 21–22°C and maintain steady moisture without saturation. Light is optional before emergence.

The current breeder sheet lists Yellow and Clear Orange while the local packets retain Bright Yellow and Bright Orange. This guide preserves the packet names and applies only the shared New Day series culture; it does not assert that the local colour names are formal breeder synonyms. New Day Tiger Mix corresponds to the striped red-and-rose mixture, while New Day Mix is the broad series mixture.

Under controlled production, plugs take 4–5 weeks and flowering plants another 8–9 weeks. In a home garden, use the packet’s broader 7–21-day germination window and about 12 weeks to first colour only as planning guidance, not a guarantee.

Frosty Kiss F1: Raw Seed and Silver Foliage

Shop this module: Gazania F1 Kiss Frosty Mix Seeds.

The product sold locally as Kiss Frosty Mix is the silver-leaved Frosty Kiss F1 mix. It is raw seed, not coated. Cover with a thin layer of medium vermiculite and keep at 21–24°C until the radicle emerges. Germination light is not required; bright light after emergence reduces stretch.

Plants are compact and upright, about 20–25 cm high and wide. The current packet uses 20 cm spacing; allow up to 25 cm in humid districts for airflow. The silver foliage keeps the planting visually useful while the flowers close at night or in dull weather. Breeder-controlled total crop time is about 13–15 weeks.

Big Kiss F1: Raw Seed and Larger Growth

Shop this module: Gazania F1 Big Kiss Mix Seeds.

Big Kiss is also raw seed, but the plants and flowers are materially larger. Use the same thin vermiculite cover and 21–24°C germination range as the Kiss culture. Expect controlled radicle emergence in 4–6 days, with a 5–6-week plug stage.

Big Kiss forms full, bushy mounds about 25–30 cm high and wide and carries large striped flowers on strong stems. The current packet’s 20 cm spacing creates a dense display; 25–30 cm gives each plant room to reach its breeder-listed width and improves airflow. Breeder-controlled total crop time is about 13–15 weeks.

How to Sow Gazania Seed

Fill clean cells with a fine, free-draining seedling mix. Moisten it first and let surplus water drain.
Sow one seed per cell. Keep New Day’s coating intact. Place raw Frosty Kiss and Big Kiss seed carefully so it is not displaced.
Cover about 1 mm deep or with a thin layer of medium vermiculite. Gazania seed in this exact scope is not left exposed on the surface.
Keep New Day at 21–22°C and Frosty Kiss or Big Kiss at 21–24°C. No soaking, chilling or scarification is needed.
Keep the root zone evenly moist until emergence, never muddy or waterlogged. Coated seed must not dry while the coating hydrates. Water with a fine mist or from below so the seed stays in place.
Give seedlings bright light immediately after emergence and begin lowering humidity. Let the surface move slightly towards dry between careful waterings while roots remain evenly moist.

Tray sowing or direct sowing?

Tray sowing is the dependable method for small packet counts because it controls warmth, moisture and losses. Direct sow only into settled warm, frost-free soil with a fine surface. Mark the position, use the same thin cover and keep the top layer consistently moist. Direct-sown coated seed is especially vulnerable if the surface dries before emergence.

Transplanting and Spacing

Move New Day plugs at about 4–5 weeks and Frosty Kiss or Big Kiss at about 5–6 weeks, or when each plug is well rooted and has several true leaves. Do not hold crowded seedlings in small cells. Harden them for 7–10 days by gradually increasing sun and wind exposure while reducing, but not withholding, water.

Plant after severe frost risk has passed and keep the crown at soil level.
Use full sun and free-draining soil. Space New Day 15–20 cm, Frosty Kiss 20–25 cm and Big Kiss 25–30 cm.
If following the current packet’s universal 20 cm spacing, recognise that Big Kiss will form a denser planting and needs closer moisture and airflow checks.
Water transplants in thoroughly, then keep the root zone evenly moist until new growth confirms establishment.

When to Sow in South Africa

Winter-rainfall Western Cape

Start protected trays in late winter for spring planting, or sow in spring once reliable warmth reaches the 21–24°C germination range. Mild, frost-free coastal gardens can trial late-summer to autumn sowing, but winter rain makes raised beds, containers and excellent drainage important. Water establishing plants through the dry summer and shelter trays from strong wind.

Frost-prone interior

Start under protection in late winter and transplant after the last severe frost. Treat these exact F1 lines as warm-season annuals rather than relying on frost resistance reported for some wild G. rigens forms. Protect young plants from cold nights and do not leave autumn seedlings exposed to repeated hard frost.

Humid coast and KZN Midlands

Sow in the cooler shoulder seasons while still providing 21–24°C for germination. Use full sun, the wider end of each spacing range, free-draining soil and early-morning watering at soil level. Remove dead leaves and spent flower stems so humid, stagnant growth does not encourage Botrytis or crown and root diseases.

Hot-dry or subtropical interior

Sow in spring or late summer to avoid the most punishing heat during seedling establishment. Keep trays bright but protected from scorching midday sun, then harden plants into full sun. Water deeply, let the upper soil begin to dry between waterings and keep mulch away from the crown. Established drought tolerance does not apply to germinating seed or new transplants.

Ongoing Care and Deadheading

Gazanias flower best in full sun and free-draining, moderately fertile soil. Shade, waterlogging and excessive nitrogen produce soft growth and fewer open flowers. Water established plants thoroughly, then allow the upper soil to start drying before watering again. Containers need more frequent checks than beds but must never stand in water.

Feeding: use a light, balanced feed only where growth shows a need; high salts can scorch leaf tips and excessive nitrogen delays compact flowering.
Pinching: routine pinching is not required for these naturally compact series.
Deadheading: trace each faded flower stem to the base and cut it cleanly without damaging the crown. Regular removal redirects energy from seed development and keeps the display neat.
Pests: inspect for aphids, thrips, mites and whiteflies. Start with sanitation, water management and physical removal; use only a correctly labelled garden treatment when necessary.
Diseases: damping-off threatens saturated seedlings, while Botrytis, Rhizoctonia and Sclerotinia are favoured by persistent wetness and poor airflow.

Flower Outcome

The current packets use about 12 weeks to bloom. Under breeder-controlled production, New Day normally takes about 12–14 weeks from sowing and Frosty Kiss or Big Kiss about 13–15 weeks. Home timing can be longer when light is low, temperatures fluctuate, seed takes the full packet window or transplants stall. Flowers open best in direct sun, close in the evening and may remain partly closed in cloudy weather.

Why Germination, Establishment or Flowering Fails

No emergence: the seed was buried too deeply, the cover dried, the tray stayed below the target temperature or saturated mix excluded air.
Coated New Day seed swells but stops: the coating hydrated and then dried. Re-sow and maintain steady moisture until emergence without waterlogging.
Raw seed moved or clustered: forceful top watering displaced it. Use a fine mist or bottom water.
Seedlings collapse: dirty containers, dense sowing, saturated mix, high humidity and low airflow encouraged damping-off.
Seedlings stretch: post-emergence light is too weak, conditions are too warm or plugs have been held too long.
Transplants stall: plants were not hardened, roots were disturbed, the soil stayed wet or frost and cold wind followed planting.
Few flowers: the site is shaded, nitrogen is excessive, faded stems remain, or plants have not yet completed their temperature- and light-dependent schedule.
Flowers close in dull weather: this is normal Gazania behaviour, not a failure. Full sun produces the best daily display.
Crown or root rot: improve drainage, widen spacing, water early at soil level and remove affected plants and contaminated mix.
