Huckleberry #890891

Asked December 17, 2024, 6:08 PM EST

Will Vaccinium ovatum (evergreen huckleberry) grow here in the Washington DC area?  I suppose it needs special soil conditions.  If it can grow here in the East, can you suggest planting and care instructions?  Thank you

Hi, 

It is native to the Pacific North West so depending on the microenvironment, it may be ok. We don't have a lot of information on them, since it isn't typically grown here. 

It does need acidic soil to be able to thrive and fertile well-draining soil. If the soil is too heavy it could succumb to root rot. The winter weather should be fine as we have been trending warmer for winter lows. If the weather is forecasted to be very cold for multiple days, 0-10 degrees F, then you may want to protect them with a frost blanket or old sheet, etc. They may suffer from leaf scorch if the area is windy. Broadleaf evergreen plants can lose water from their leave in the winter if the ground is frozen and it is sunny or windy as the roots cannot take up enough water to replace what is being lost. Typically if the symptoms are not too severe, plants will put out new growth in the spring and the damaged leaves will eventually fall off.

If you wanted to experiment with just one or a few, you will want to make sure the soil conditions are right. You can have your soil tested at a laboratory.  This can tell you the pH or acidity level and nutrients. You can also test it for drainage by doing a perc test. Adding organic matter such as leaf compost, or top soil can help amend heavy clay soil and improve drainage. You will want to make sure to thoroughly mix it into the planting area to incorporate it throughout. 

For lowering your soil pH you can follow the guidelines on our webpage and also Penn State's page is helpful as well: https://agsci.psu.edu/aasl/online-report/home-garden
