Zinnias are an annual flower that can add a variety of color to the garden. They are available in small miniature varieties and giant varieties that can grow quite tall. They are a warm-weather flower that blooms from late June until the first frost. Zinnias are easy to grow and care for, perfect for a low-maintenance garden. Miniature zinnias work well in outdoor containers and pots and the giant variety can be used to make striking flower arrangements.
Things You'll Need
Seeds
Starter pots
Soil
Compost
Sand
Mulch
Fertilizer
Sow zinnias inside 3 to 4 weeks before the last frost date. Sow the seeds on the surface of the soil and cover loosely with soil. Keep the soil moist in a warm, sunny place.
Prepare your garden bed by mixing in compost. Zinnias prefer well drained soil so add a small amount of sand if necessary.
Transplant the zinnias outside after all danger of frost. Space them 4 inches apart for small varieties and up to 2 feet apart for large varieties.
Keep the soil moist, watering up to 2 times per week. Mulch around the plants to help them retain moisture.
Add a general-purpose fertilizer to the soil monthly during the growing season. Deadhead the spent blooms by gently pinching them off to encourage continued flower production.
Tips & Warnings
Cut the stems near the base for indoor flower arrangements.
Hard frost will kill zinnias, cover them if a light frost is expected.
