Zinnias are a must for anyone wanting glorious, long-lasting colors throughout the garden, as well as for cut flower arrangements. The more you cut, the more they bloom!
Since 1925, California Giants has delivered large blossoms on heat-loving, tall plants. Each flower lasts a long time on the plant and in the vase. Pollinator-friendly and deer resistant!
Zinnia may be grown from seed sown early indoors and transplanted outside after frost, or sown directly in the garden after danger of frost passes. Sow seeds indoors three to four weeks before the last frost, placing one quarter inch deep in seed starting mix and keeping soil moist and warm. As soon as seedlings emerge, provide plenty of light on a sunny windowsill or beneath fluorescent plant lights. Thin to one seedling per cell when they have two sets of leaves. Transplant hardened-off seedlings to the garden after the danger of frost passes, spacing them 18 inches apart.
If sowing directly in the garden, work organic matter into the top 6–8 inches of soil, then sow seeds in full sun after danger of frost passes. Sow seeds 12–14 inches apart and over with one quarter inch of fine soil. Firm soil lightly with your hand, water, and keep evenly moist.
Wait until flower petals have dried out, then cut off dried flower heads and place them on a paper towel or plate. Separate out dried flower petals, leaving only the seed pods (hold seed pod between your thumb and index finger, then gently pinch off faded petals). Open the seed pod to release seeds. Spread seeds on a paper towel and allow them to dry fully for about one week. Store dry seeds in a cool, dark place for three to five years.
