Will Zinnias Bloom All Summer? Ways to Help Your Zinnias Keep Blooming All Summer

Yes, zinnias will bloom all summer long! Depending on the variety, they may start to flower as early as May and continue blooming until late fall. Some varieties produce larger flowers than others, so there’s a little something for everyone regarding zinnias. If you’re looking for colorful arrangements that can be enjoyed throughout the season, look no further than your garden or zinnia farm!

Since zinnias are annual plants, they don’t come back next year. In other words, the flowers’ whole life cycle happens in one year.

Ways to Help Your Zinnias Keep Blooming All Summer

Prune the Plants

If you want your zinnia plants to keep multiplying and flowering, you must clip off the blooms as they appear. Zinnia plants require minimal pruning. Simply wait until they reach a height of 10 to 12 inches. Make sure they have at least two full sets of leaves. When the plants reach this height, you should prune them. Remove the top 4 inches or the two sets of leaves with a sharp pair of pruners.

Avoid Overwatering

Zinnias are annuals, so they need to be watered only when the soil is dry. Overwatering zinnia plants will cause their foliage to droop and turn yellow or brown.

Give Plenty of Space

Zinnias need plenty of space to bloom. Give them at least 6-8 inches of spacing between each plant. You can also tie the stems up with twine, but be sure to cut the strings after they bloom because bees and other insects pollinate zinnia flowers.

Soil Well in Pitcher Plant Soils

Add 3 parts well-drained soil and 1 part compost or garden fertilizer to your potting soil before planting zinnias. Do not plant zinnias in sandy soils, as this will cause them to have difficulty retaining moisture, which can lead to dead flowers. Zinnias need good air circulation, so make sure your garden has open spaces where the zinnia plants can get plenty of sun and CO2.
