Sow indoors 4 weeks before your last frost.
Transplant out after danger of frost.
Direct sow after last frost.
Note: Take care to keep plants from becoming root-bound and be very gentle when transplanting. If desired, you may sow/transplant every 2 weeks for production flower farming.
9-12" in rows 1.5-2' apart.
3-7 days @ soil temp 75-85F
Full sun to part shade
Medium. Tolerant to most soil types but prefers rich, evenly mosit soil with a pH between 6.0-7.
While not absolutely necessary, you may provide a staking or netting to keep them upright and tidy.
Be gentle with the roots when transplanting to avoid stress that can cause more single (as opposed to doubled) flowers.
To encourage branching, pinch initial bud when 12" tall.
Zinnias appreciate some cooler time and/or shade.
Continue to cut and deadhead and the plant will be wildly floriferous!
Stiff cut stems have a 7+ day vase life.
