Gerbera Daisies are grown from seeds. Plant seeds directly into the garden or start plants indoors. For indoor starts, sow seeds 10-12 weeks before the last frost date for your area. Sow seeds lightly or press lightly into the soil. The seeds need light to germinate.
Transplant seedlings into their outdoor summer home after all chance of frost has passed.
Garden Tip: Use peat pots or pellets, as the plant does not like to have its roots disturbed when transplanting.
Days to Germination: 10 – 20 days, depending upon the variety.
The crowns of established plants tend to sink down into the soil. This can cause crown rot, especially in wet soil. Dig up and re-plant them as needed.
The plants can also be propagated, by division. Dig up plants, separate them into clumps, and re-plant the clumps. As previously mentioned, it is important to plant the crowns above the soil level.
Plant Spacing: Plant Gerber Daisies 18 to 24 inches apart.
Grow Gerber Daisies in full sun. However, in hot regions, plant in an area that offers partial shade from the hot afternoon sun.
The plants grow best in rich, highly organic soil that is well-drained soil. Mix in a generous amount of compost when planting them.
Weed around plants when young. Also, apply a thick layer of mulch to help keep the weeds down and to retain soil moisture.
Apply a general-purpose fertilizer once a month. Start with a high nitrogen fertilizer. Then, switch over to a high Phosphorous formula just before blooming. This helps to promote blooms. Also, use liquid fertilizer on both garden and container-grown plants.
Water the plants, especially in dry weather. Apply water deeply. Then, allow the top of the soil to dry before watering again.
Maintain the health and appearance of the plant by pruning as needed. Remove dead and unhealthy leaves and branches.
Deadhead spent flowers to promote continuous blooms. Cut flower stems back to where it meets the plant branch. Of course, if you are regularly cutting flowers for indoor vases, you won’t need to deadhead plants too often.
Days to Germination: 10 – 21 days, depending upon the variety
