PLACEMENT & CULTIVATION
Perfect for mixed borders and beds, zinnias will brighten up almost any location with full sun and rich, well-drained soil. They are easy to grow and versatile, thrive in varying soil conditions and are easily transplanted, even when growth is significant. Pinch back when seedlings reach about 6-8" in height to encourage bushy growth, and deadhead regularly for a midsummer to frost show.
Tolerates drought, but performs best when watered regularly. Keep moist, watering only in the morning. Avoid wetting the leaves.
Mix in an organic, all-purpose granular fertilizer soon after planting out, and again when flowering begins.
Diseases & Pests:
Avoid fungal issues by spacing properly and placing in a location with good air circulation. If problems arise, treat with an organic fungicide or neem oil. If slugs are troublesome, treat the surrounding soil with pelletized iron phosphate. Diatomaceous earth or crushed eggshells can also be spread on the surrounding soil to prevent or resolve this issue.
When to Cut for Bouquets:
