Growing Zinnias in Zone 9A

Zinnias are the cut-and-come-again champions — the more you cut, the more they bloom.

Zone 9A has a very long growing season with mild winters. Many crops can be grown nearly year-round with successive plantings.

Top Growing Tips

• Direct sow after frost — they’re fast growers
• Space properly for air circulation to prevent powdery mildew
• Cut for bouquets regularly — it encourages more flowers
• Benary’s Giant, Oklahoma, and Queen Lime are popular cut flower varieties
• Butterflies love zinnias — plant near vegetable gardens to attract pollinators

Companion Planting

Good companions: any vegetable garden — great pollinator attractors

Avoid planting near: none — zinnias play well with everything

Harvest Timeline

Flowering begins 60-70 days from seed; cut when petals are firm
