Newsletter

Danziger offers three Osteospermum series, giving growers different options for production and finished-product needs, while bringing bold color and strong flower impact to retail: BESTIES™ with a uniform, well-branched habit suited for small pots; OSTICA™ with controlled growth and a balanced, mounded habit; and OSTICADE™ with a controlled semi-trailing habit, especially suited for baskets.

Your Osteospermum Early-Spring Production Roadmap

Plan your 12 cm (5″) Osteospermum crop to be retail-ready by Week 13-14

Osteospermum series: ordering and propagation (W40-W52)

Timing	Stage	What to do?
1W40-W47	Ordering	Place your order in advance, because this ensures cutting availability.
2W48-W50	Plan & Stick	First, stick cuttings and spray adjuvant after sticking. Also, IBA or K-IBA treatment may accelerate rooting. Maintain a propagation temperature of 70-72°F (21-22°C) and begin feeding at 50 ppm N. Then, on the day of sticking, apply a fungicide and daminozide at 2,500 ppm. In addition, night-interruption or extended-day lighting during propagation can promote earlier flowering.
3W50-W52	Rooting	Then, begin cooling to 65-68°F / 18-20°C and increase feed to 100-150 ppm N. Maintain pH 5.8-6.2 and EC around 0.9-1.0.

Osteospermum series: liner and transplant (W52-W3)

4W52-W2	Build the Liner	Meanwhile, maintain 65-68°F / 18-20°C, feed 100-150 ppm N, and build EC toward 1.0-1.2. Also, apply Daminozide as needed to control stretch.
5W1-W3	Transplant	After approximately 5 weeks of propagation, transplant into the final 12 cm (5″) pot. Also, maintain pH 5.8-6.2, EC 1.0-1.2, and apply fungicide after transplant. However, pinching is generally not recommended when plants are compact; if needed under warm conditions, pinch at transplant above 5-7 pairs of leaves.

Osteospermum series: finishing and shipping (W9-W13)

6W9-W11	Finishing	Meanwhile, grow at 65-68°F / 18-20°C and feed 100-150 ppm N. Also, no additional lighting is required. Then, maintain consistent soil moisture, allowing the soil to dry slightly between irrigations, and keep foliage dry entering the night. Then, use Daminozide as needed; Paclobutrazol drench 1-2 ppm can be applied when plants reach about 85% of desired size.
7W11-W12	Final Quality	Finish cool for the best plant quality. Then, check crop uniformity, flower development and finished size. Also, maintain dry foliage and avoid excessive moisture before shipping.
8W12-W13	Ship & Retail	Then, ship market-ready Osteospermum to retail with vibrant flower coverage and strong shelf appeal, ready to bring early-season color to consumers.

iThis schedule is a general guideline for 12 cm (5″) Osteospermum pots. Results may vary depending on series, variety, location, season, light levels, growing conditions and crop management. For detailed PGR, lighting and propagation recommendations, follow the technical guide for the selected Osteospermum series.
