Zinnia flowers (Zinnia elegans) bring vibrant, long-lasting color to any garden. Once you know how to plant them for your specific area, you can easily add these cheerful annuals to sunny spots that could use a pop of bright blooms.
How to Grow Zinnias
Growing zinnias doesn’t have to be expensive, especially if you start them from seed. Since their roots don’t like being disturbed, it’s best to sow zinnia seeds directly into a sunny flower bed.
If you prefer starting seeds indoors, use peat pots, poo pots (cow dung pots), or other biodegradable containers that can go straight into the garden later.
Begin seeds four to six weeks before your area’s last frost date. Zinnias start growing outdoors once temperatures stay above 50°F (10°C). When planting, space seeds properly—usually a few inches to a couple of feet apart (8-61 cm), depending on the mature plant’s size. This spacing ensures good airflow as they grow.
Zinnias planted too close together or watered from above can develop powdery mildew and other diseases. While seeds offer the widest variety of colors and heights, you can also find starter plants at local garden centers.
Caring for Zinnias
Water zinnias at the base—a soaker hose works great to keep leaves and petals dry while giving them the moisture they need. Morning watering is ideal, letting everything dry before nightfall.
Keep young plants’ soil moist (but not soggy). Mature zinnias need less water since they’re somewhat drought-tolerant. With the right spot and proper watering, zinnias keep your summer garden colorful and beautiful.
Extra Zinnia Care Tips:
- Deadheading and cutting flowers for bouquets encourages more blooms.
- Trimming the plant back often leads to fuller growth.
- Pinching young stems creates bushier, more attractive plants.
If you want bold, bright color in your garden this summer, try growing zinnias!
