zinnias in pots

Zinnias are one of the most popular flowers for gardeners, thanks to their vibrant colors and easy-to-grow nature. However, many people don't have access to a garden or simply prefer the convenience of growing plants in pots. In this guide, we'll explore everything you need to know about growing zinnias in pots.

Choosing the Right Pot

The first step in growing zinnias in pots is choosing the right container. Zinnias need plenty of space to grow, so opt for a pot that is at least 12 inches deep and wide. It's also important to choose a pot with drainage holes to prevent water from accumulating and causing root rot.


Next, you'll want to choose the right substrate for your zinnias. A good potting mix is essential for healthy growth, as it provides the necessary nutrients and drainage. Look for a mix that contains perlite or vermiculite for added drainage, and avoid heavy soils that can hold too much moisture.

Planting Your Zinnias

Once you have your pot and substrate, it's time to plant your zinnias. by filling your pot with potting mix until it reaches about an inch below the rim. Next, make a small hole in the center of the pot and place your zinnia seedling inside. Fill in around the seedling with more potting mix, making sure not to cover the stem.

Watering and Fertilizing

After planting your zinnias, it's important to keep them well-watered and fertilized. Water your plants deeply once a week, making sure the soil is moist but not waterlogged. You can also add a slow-release fertilizer to the potting mix or use a liquid fertilizer every two weeks.

Caring for Your Zinnias

Zinnias are relatively low-maintenance plants, but they do require some care to thrive. Here are a few tips for caring for your zinnias in pots:


Deadheading is the process of removing spent flowers from your zinnia plant. This encourages more blooms and prevents the plant from putting energy into producing seeds. Simply pinch off the dead flower heads as they appear.

Pest Control

Zinnias can be prone to aphids and spider mites, which can damage the leaves and flowers. If you notice these pests on your plants, spray them with a gentle insecticidal soap or neem oil.


As your zinnias grow taller, they may need support to prevent them from toppling over. You can stake them using bamboo poles or other supports, being careful not to damage the roots.

Harvesting and Saving Seeds

One of the great things about zinnias is that they produce abundant seeds, which can be saved and planted again next year. To harvest zinnia seeds, simply wait until the flowers have dried up and turned brown. Then, remove the seed head and shake out the seeds onto a piece of paper. Store the seeds in a cool, dry place until you're ready to plant them.


There are many different varieties of zinnias to choose from, each with its own unique color and size. Some popular varieties include the Zahara series, which features compact plants with large, vibrant blooms, and the Benary's Giant series, which produces enormous flowers up to six inches across.
