Can I Grow an Avocado Tree in Oregon?
Oregon is known for its lush and varied landscapes, and has the perfect weather to allow production of all manner of edibles. People may be surprised to learn however, that while the state is ideal for the production of things like apples and berries, it is not very conducive to growing an avocado tree. While it may be possible to grow such a tree in Oregon’s regions of Willamette Valley, Rogue Valley and Umpqua Valley, it is not very likely to be successful.
Frost Damage is the Main Reason Avocado Trees Don’t Stay in Oregon
The main reason why the majority of people opt not to have an avocado tree in their Oregon garden is that due to the state’s cold winter temperatures, the tree is prone to frost damage. This can sometimes cause irreparable damage – as low temperatures of -20°C will cause avocado trees to shut down temporarily, sometimes leading to stunted growth.
Experts agree that in order to grow a healthy, fruit bearing avocado tree, Oregonians need to make sure they choose a variety that is cold tolerant – such as the ‘Lee’ variety. Many nurseries in the state will carry this variety of the tree. It is important to note though that because Oregon experiences a longer and colder winter than other parts of the US, it may not guarantee successful avocado tree growth.
What are the Growing Conditions of an Avocado Tree in Oregon?
When it comes to growing an avocado tree in Oregon, the specifics of the growing conditions need to be considered. Generally, avocado trees need full sun and slightly acidic soil (pH should be between 6.0 and 6.5). Established trees should be irrigated every week during growing season, while younger trees should be watered more often. The care that an avocado tree requires in Oregon is a lot more labor intensive than other fruit trees like apples, as it is particularly susceptible to frost damage.
Can Avocado Trees Survive without Protection?
Because of the risk of frost damage, the majority of people who grow avocado trees in Oregon opt for some kind of protection. This can be in the form of fleece which is wrapped around the tree when low temperatures are forecast, or by using a greenhouse or polytunnel as a more permanent shield from the cold. Both of these methods will help to protect the tree from frost damage, making it more likely to survive the colder months of the year.
Conclusion
Due to the frost risk in Oregon’s winter climate, it is hard to recommend the planting of an avocado tree in the state. Those who want to give it a try should choose a particularly cold tolerant variety, such as the ‘Lee’ avocado, and make sure to protect the tree in cold weather. While there is a risk of failure in trying to cultivate an avocado tree in Oregon, there is always a chance that it may be possible to successfully grow one.
Alternative Solutions
Though growing an avocado tree may be challenging in Oregon, there are other solutions for avocado lovers. For example, one can seek out local farmers’ markets, or growers who work with the more cold-resistant varieties recommended for the state. Another option is to look for the hardiest avocado trees and plant indoors in a container for a warmer climate.
The Challenges of Caring for an Avocado Tree in Oregon
For those in Oregon who take on the experimental challenge of growing an avocado tree, proper care is important. These trees require higher levels of care than other fruit trees in the state, such as apples. For optimal growth and harvests, avocado trees should be regularly watered and shielded from frosty temperatures during the cold months. In addition, like any fruit tree, young avocado trees require protein fertilizer once or twice a season in order to develop.
Drought-Resistant Varieties Available
If an Oregonian wishes to give an avocado tree a home in their garden, they should also be aware that there are drought resistant varieties available – such as the ‘Bacon’ or ‘Fuerte’ avocado. These varieties require less water than other types, so those living in drier climates can learn more about these and decide if it is worth a try. Drought-resistant varieties have a better chance of surviving in drier conditions, making them a better option for those in more arid climates.
Access to Organic Avocado Fruit
For those in Oregon who are unable to successfully cultivate an avocado tree in their backyard, there is still a solution. Buying organic avocados from local farmers allows for access to nutrient-dense fruits without the worry of pesticides and fertilizers. Plus, it supports the local economy, lowering costs and creating jobs.
Common Pest and Disease Issues
Pest control is also an important factor in the cultivation of an avocado tree in Oregon. Different pests can attack the tree’s fruit and leaves, like mealy bugs and whitefly, which will require regular monitoring and pest management. If the right pest – and disease – prevention methods are not implemented, the health of the tree could be compromised.
Alternative Uses of the Avocado Tree
Those with an avocado tree who live in areas where it is unlikely to ripen can still benefit from its presence. Ornamental features like leaves and wood can be harvested for use in crafts, and the tree can be utilized for shade and shelter for other plants in the garden. Though it may not bear fruit in Oregon, the presence of an avocado tree can still leave its stamp on a garden.
