When Do Kalmia Bloom in Minnesota?

As you may have already guessed, there are two main factors that determine when Kalmia will bloom: where your Kalmia are planted & weather (time).

Bloom Time Depends on Where Your Kalmia Are Planted!!!

When your Kalmia will bloom will depend on exactly where it is planted in your yard or garden

In general, expect the following:

  • If a kalmia 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 kalmia is planted in an area of your yard that received partial sun it will bloom around the same time every year.
  • If a kalmia 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.
