Growing Zinnias in Pots

If you’re looking for an easy starter flower for your container garden, zinnias are the answer! As one of the simplest plants to grow, you’re almost guaranteed to have bright bursts of color in your garden through spring and summer. As annuals, zinnias growing in containers will only last for one year, but you can reseed them each spring in new colors. There are three types of zinnias, including single, double, and semi-double. These names refer to the number of rows of petals they have and whether the flower’s center is visible. 

In addition to their variety of colors and petal structures, zinnias also come in several shapes, including button, beehive, and cactus. Learn more about growing zinnias in pots from Patio Growers today!

Sowing Your Plants

Zinnias are adaptable to most growing conditions, but they do require full sun to thrive. You’ll also want to grow them in an area that has good air circulation to prevent mold and mildew from attacking your plants, like a balcony. Zinnias don’t like to be transplanted, so it’s best to grow them from seed after the last frost has passed. If you want to extend the flowering period of your zinnias, we recommend sowing a round of seeds every week for about a month. When growing zinnias in containers, it’s a good habit to cut off old flowers to encourage new blooms.
