Avocados are a much-beloved fruit that many people enjoy in salads, guacamole, and smoothies. However, what many people don’t know is that this popular fruit is actually the seed of a small tree – the avocado tree. The avocado tree is relatively easy to cultivate – but only in certain climates and settings. Can an avocado tree actually grow in Illinois?
Illinois sits in the U.S. Department of Agriculture (USDA) hardiness zone 5. As a Treehugger article explains, for the avocado tree, “USDA Zone 5 is a bit on the cool side for the avocado tree.” Avocado trees need a subtropical climate to thrive, preferably from zone 9 to 12. Since this type of warm climate is unavailable in Illinois, the avocado tree cannot actually grow in the area. USDA Zone 5 is just too cool for the avocado tree.
That said, growers in colder climates have had some success growing avocados. Some resources recommend bringing an avocado tree indoors during cold weather and allowing it to bask in warmth and sunlight when possible. They advise against doing this, however, as the activity can put a strain on the plant’s health and lead to weakened growth or even death. The article concludes that, while an avocado tree can sometimes be grown in cooler climates, it’s not advisable to do so.
Another article from DIY Network shares similar advice: cooler climates such as USDA Zone 5 are unfriendly for the avocado tree. As the article explains, “To survive and thrive, avocado trees need summer heat and mild winter temperatures, which make them delicate plants to grow.” The article then goes on to confirm that, for the success and health of an avocado tree, it “must be planted in U.S. Department of Agriculture plant hardiness zone 9 or higher.” The article concludes that, while an avocado tree can’t be grown in Illinois, one can consider growing “dwarf varieties in containers,” as these are easier to manage in colder climates and may also be suitable for growing indoors.
Harvesting Avocados
The article by DIY Network also explains that, even if you do manage to produce a viable avocado tree in Illinois, harvesting the fruit may present some obstacles. The article mentions that the cold climate may cause irregular blooming and fruiting – meaning that despite a successful harvest, the yield may be irregular or lower than expected. The article then advises that, if the weather is cold or uncomfortable, it may be best to let the fruit mature on the tree rather than harvesting it too early.
Of course, this is mostly theory – there are some brave and intrepid souls who are growing avocados in cooler climates such as Illinois. As mentioned earlier, growing avocados in a cool climate is simply not recommended, so if you’re determined to try it, proceed at your own risk. But, as this article has shown, there are risks involved.
Growing Conditions for the Avocado Tree
The avocado tree does best when grown in sunlit environments, or at least partially sunny. If grown in an environment such as a greenhouse, the plant should receive at least several hours of direct sunlight per week in order to thrive. The soil must also be nutrient-rich, well-draining, and slightly acidic. If soil doesn’t meet these standards, the avocado tree may experience stunted or weakened growth. Consider enriching the soil with compost or fertilizer to ensure that the avocado tree’s nutrition requirements are met.
The avocado tree is also relatively easy to prune and train, allowing it to take the shape of any desired configuration. This can allow it to fit into whatever indoor or outdoor space is available. In addition, many avocado trees can be grown in containers indoors – again, best if it can receive several hours of direct sunlight.
Nurseries and Plant Selection
For those still determined to grow an avocado tree in Illinois, one option is to purchase a mature tree from a nursery. Though these trees may not be as healthy as one grown from seed, they may bear fruit much faster – and could be a good option if one is in a hurry for fresh avocados. Additionally, there are many “dwarf” varieties of avocado trees that are usually recommended for cooler climates, and may again be easier to manage and provide fruit faster.
When purchasing a tree from a nursery, make sure to select one that is healthy and strong – and preferably one that has already been exposed to cooler climates. Before committing to a purchase, make sure to ask the nursery about the tree’s history and make sure it’s a good fit for your environment.
Risks and Benefits of Growing Avocado Trees in Cold Climates
As this article has shown, successfully growing an avocado tree in Illinois is a risky endeavor. While the risks are outlined in this article, it’s recommended that further research is done in order to make an informed decision. Additionally, the rewards may be worth the effort – with a little luck, one can produce one’s own avocados in the comfort of one’s own garden or balcony.
Location and Climate Requirements
Finally, keep in mind that avocado trees mustn’t be placed in a spot that is too exposed to wind or cold temperatures – and be sure to follow planting instructions, as those will vary from tree to tree. Additionally, the tree should be monitored for signs of distress or poor health, and be sure to assess the climate regularly. For instance, an unusually cold winter could mean trouble for an avocado tree.
In conclusion, while an avocado tree can theoretically be grown in a cooler climate such as Illinois, it is far from a guarantee. While such a feat can be achieved with some luck and careful management, it is a risky endeavour – one that should be entered into only with full knowledge of the potential risks and rewards.
