Some tips for avocado tree care include keeping the trees in the average temperature range of 60 to 85 degrees Fahrenheit until the tree is grown and planting trees between the months of March and June, according to the California Avocado Commission. Once the avocado tree is grown, it can withstand temperatures as low as 28 degrees Fahrenheit, though it is always best to keep it away from freezing temperatures.
It is also best to be careful with the root system while transporting a tree, notes the California Avocado Commission. The trees do best with redwood bark or shredded tree bark for mulch. The avocado tree should also be watered two to three times each week. Growers should be sure that the soil has dried considerably before watering again, as it damages the plant if it is watered too frequently.
