Seed To Bloom:
Sow 6-8 weeks before last frost. Sow seeds thinly and keep at 65-75°F.
Direct sow at last spring frost date for later summer blooms.
PLACEMENT & CULTIVATION
The full branching form and aromatic forest green foliage of marigolds make them great backdrops for early summer bloomers. As the weather starts to cool at night in mid-summer, they come into their own, and every branch seems tipped with flowers of mahogany red and glinting gold. They are useful in borders, along garden edges, and in veggie gardens, for they naturally repel insect pests. The flowers are good cut, as long as you appreciate their earthily-scented leaves. Deadhead for continued bloom until frost.
About 1" per week, though it will tolerate some drought once established.
Prefers slightly acidic to neutral.
Mix in about an inch or two of compost or some organic granular fertilizer when transplanting. Flowers well with little added fertilizer, too much and foliage will be lush and flowers less abundant.
Diseases & Pests:
Be sure to space properly to increase air circulation and avoid fungal issues such as leaf spot. Japanese beetles can be hand-picked into a bowl of soapy water. If insects such as spider mites, aphids, thrips, or whiteflies are an issue, treat with an insecticidal soap.
When to Cut for Bouquets:
Harvest when fowers are fully open.
