Are you growing zinnia in California, but don’t know when they’ll bloom?
Getting your Zinnia to bloom is not as easy as it seems.
- Zinnia have a small window when they bloom and still look great.
So if they bloom too early they may die or not last as long. And if they bloom too late they may have small blooms that don’t last long.
Today, I’m going to teach you the ideal time for Zinnia to bloom in California:

When Do Zinnia Bloom in California?
As you may have already guessed, there are two main factors that determine when Zinnia will bloom: where your zinnia are planted & weather (time).
Bloom Time Depends on Where Your Zinnia Are Planted!!!
When your zinnia will bloom will depend on exactly where it is planted in your yard or garden
In general, expect the following:
- If a zinnia is planted in an area of your yard that receives full sun it will bloom around the same time every year or up to two weeks early due to warm weather and extra sunlight.
- If a zinnia is planted in an area of your yard that received partial sun it will bloom around the same time every year.
- If a zinnia is planted in an area of your yard that receives shade and is not protected from wind or rain it will bloom anywhere from 1 to 3 weeks later than its average time.
