Overview
Marigolds are one of the easiest and most rewarding annuals for East Texas gardeners. With their vibrant blooms and classic appeal, marigolds make a cheerful addition to flowerbeds, and container arrangements. These tough, sun-loving plants thrive in our hot climate and bloom from spring until frost.
Light Requirements
Marigolds thrive in full sun, needing at least 6 hours of direct light daily. More sun encourages stronger stems and a higher number of blooms. In too much shade, plants may become leggy and produce fewer flowers.
Soil & Planting
Plant marigolds in well-draining soil enriched with compost or aged organic matter. Avoid heavy soils that stay too wet. Space smaller varieties (like French marigolds) 6–9 inches apart, and larger African types 12–18 inches apart.
Watering
Water when the top inch of soil is dry, but avoid soggy conditions. Overwatering can lead to mildew and root rot. In containers or hot spells, more frequent watering may be needed. Always water at the base to keep foliage dry.
Fertilizing
Marigolds do not require heavy feeding. A light application of balanced fertilizer (like 10-10-10) every 3–4 weeks will keep them blooming vigorously. Avoid excessive nitrogen, which promotes foliage over flowers.
Seasonal Care
Deadhead spent blooms regularly to encourage continuous flowering. At the end of the season, pull up spent plants and compost them or let them reseed naturally. In East Texas, marigolds are typically grown as annuals.
