Zinnia
Sow seed indoors 4 weeks before last frost date or direct seed outdoors when soil has warmed. Germinates best at 27-30 degrees Celsius. A heat mat will speed germination. Lower temperatures result in slower germination. Sow seed 1.5-2 cm deep and transplant outdoors before seedlings become root bound. Transplant carefully so as not to disturb roots and space plants 25-35 cm apart. Double flowers may revert to singles due to transplant shock. Plant in full sun in rich soil. Pinch out the growing tips for bushy plants. Cut flowers before completely open.
