Bud Formation
2-3 weeksFlower buds appear at stem tips, plants continue to fill out and develop more branches
Reduce nitrogen fertilizer, switch to higher phosphorus bloom formula, ensure adequate sunlight and air circulation
Flowering

Garden Border & Container Display

Traditional Herbal Uses

Harvest Tips
Cut flowers in early morning when stems are fully hydrated for longest vase life. Remove lower leaves and cut stems at 45-degree angle. Flowers typically last 7-10 days in a vase with fresh water changed daily. For continuous garden blooms, deadhead spent flowers regularly by pinching off just below the flower head.
