Growing Avocados in Maryland – What To Know
Commercially, avocados are grown in California, Hawaii, and Florida.
However, the weather in Maryland is quite adequate for growing avocados in your garden, but you have to be vigilant with the unpredictable weather conditions and be ready to move the tree indoors for protection.
This is why it’s recommended to grow the avocado tree in a container in Maryland.
Avocado Temperature Tolerance
Avocado trees come in different varieties. Since each variety is native to a different region, the temperature tolerance of avocados varies widely.
The Guatemalan avocado has a high tolerance for cold temperatures and can handle temperatures between 26 and 30 degrees Fahrenheit.
West Indian avocados have the least tolerance for cold weather and need steady temperatures between 60 and 85℉ all year round to thrive.
But if you’re looking for cold hardy avocados that can handle the occasional frost and cold spell, then Mexican avocados are the ideal variety.
Mexican avocados are known to survive in regions where the winter temperature can drop to 19℉.
Maryland Temperature Ranges
Maryland has the right summer for growing avocados as it’s usually hot and humid. The temperature can reach 87℉ and rarely goes above 95℉.
However, the winters are a little too cold and windy for many avocado types. The average temperature in the winter is between 23 and 25℉.
Due to the state’s chilly and snowy winters, the best avocado variety to grow in Maryland has to be Mexican avocado.
Their fruits are smaller than the other types, but they’re not phased by frost or the occasional dip in temperature.
Can You Grow an Avocado Tree Inside?

Prune the tree regularly to manage its height, and avoid exposing the sapling to direct sunlight.
