How to grow avocados in a cold climate

Avocados have tough characteristics, wrinkled green skin and creamy flesh with a seed in the center the size of a ping-pong ball. Wrinkled skin gives avocados an additional name “crocodile pear”. This subtropical tree grows best in warm areas with mild winters. People who live in areas where temperatures fall below 35 degrees Fahrenheit (1.6ºC) should not grow avocados in the soil. Avocados, however, can be done very well in pots, in all climates and seasons.


1-Wash the avocado seed with cold water to remove the pulp of the avocado. Place a water rate in the microwave for 45 minutes. Soak the seed in hot water [about 105ºF (40.5ºC)] for one minute to remove mold and potential bacteria. Cut about 1/4 inch from the tip and submerge the cut part in the fungicidal liquid.

2-Fill a 16-ounce pot (453.5 g) with soil for Sandy pots. Push the seed, with the round end down, into the fertilizer. Leave the cut part and top of the seed 1/8 of an inch below the exposed. Water the soil around the seed until it is moist but not muddy.

3-Place the avocado seed in a warm, sunny window or outdoors in summer. Sprinkle the seed as in the previous process every three days until it grows 6 inches (15.24 cm) tall.

4-Fill a 5-gallon (18,92-liter) pot with potting soil. Move the germ of the seed to the new pot, untangling the roots before settling it to the new hole with the size of the root ball. Cover the roots, and water the earth as usual. Leave the avocado tree outdoors, as long as the weather is warm.

5-Move the pot with the avocado tree indoors when the nights cool to temperatures of 50ºF (10ºC) or less. Place the pot in a room with plenty of natural light and keep temperatures at approximately 60ºF (15.5ºC). Water the pot as usual, and make sure there are no drafts coming from the windows.


  • If you are in a temperate climate, you can move your avocado tree south, southwest and southeast of the house. These areas are the warmest and the avocado tree will be protected from storms and frost.
