Temperature requirements
Avocados, originally native to tropical climates, cannot be grown in Ohio because of the state’s extreme winter temperatures. The warmest temperature this tree species will tolerate is 15°F, which is 10 degrees lower than the average winter temperature in Ohio. Thus, in order for a homegrown avocado tree to survive, it must spend the winter indoors a warm location, like a heated greenhouse. It is not recommended that the tree be brought indoors and out of doors each winter, as this will stress its growth cycle and fruits will be difficult to get.
Sunlight requirements
In order to promote optimal growth, an avocado tree needs 8 hours of direct sunlight each day. In Ohio, this could be challenging, as the sun is not often seen during winter months. Additionally, because of the state’s humid climate, an avocado tree will require protection from heavy rain and wind in order to stay healthy. Invest in a shade cloth and use it to improve the tree’s overall temperature and light intake.
Soil type and Fertilizing needs
Avocado trees like slightly acidic soils with a pH level between 5.5 and 6.7. In addition to a soil with good drainage and aeration, the tree should be regularly fertilized throughout the summer and spring. A balanced 8-8-8 fertilizer will be adequate for the tree’s nutrient needs. Also, add a water-soluble fertilizer every other month during the growing season to boost the tree’s growth.
Pruning and Controlling Pest and Disease
Avocado trees don’t require a large amount of pruning in order to stay healthy. However, it is important to remove any dead or damaged branches to ensure that the tree’s growth remains unaffected. Additionally, since the tree is vulnerable to a wide variety of pests, it is important to inspect the tree’s branches and leaves on a regular basis. If any insects or disease-causing organisms are discovered, they should be treated immediately.
Finding and Planting Avocado Trees in Ohio
Finding an avocado tree in Ohio can be a challenge. While some local stores offer trees for sale, their limited selection and high prices might be a deterrent. It is recommended that gardeners explore online nurseries for high-quality avocado trees at affordable prices. There are some nurseries that specialize in avocado trees and can ship trees to Ohio. Once the tree arrives, it should be planted in well-drained soil and watered regularly.
Pests and Disease Prevention
In addition to taking care of the tree’s basic needs, a homeowner must also be mindful of the tree’s potential pest and disease problems. It is important to inspect the tree regularly for signs of insect infestations or infections. If any such signs are found, they should be addressed immediately to prevent them from spreading. A variety of natural treatments, such as using neem oil or garlic sprays, can be used to combat these problems.
Harvesting Avocado Fruits in Ohio
Due to the cold winter temperatures in Ohio, avocado fruits will not ripen on the tree. This means that the fruits must be harvested while they are still green and unripe. They will ripen off the tree, but the window for ripe avocados is limited. Generally, they should be harvested in early summer before the fruit has reached its peak ripeness. If the fruit is left to ripen on the tree, it will be susceptible to birds and other animals that may eat it before it can be harvested.
Preserving and Storing Avocado Fruits in Ohio
It is important to store unripe avocado fruits in order to ensure that they ripen properly. When stored in a cool, dark location, the fruits will ripen within a few weeks. Once they have ripened, they should be eaten within a few days in order to avoid spoilage. If they are not eaten within this timeframe, they can be frozen for up to one year. They can then be thawed and eaten when desired.
Container Growing Avocado Trees in Ohio
Container growing is a good option for the Ohio gardener who wants to successfully grow an avocado tree in the state. The container should be large enough for the tree’s root system and designed to provide adequate drainage. The tree should be placed in a location that receives full sun and be kept out of direct winds and heavy rains. The container should be lined with mulch that is 6-inches deep and be protected from freezing temperatures during the winter months. Also, the tree should be regularly watered and fertilized to ensure optimal growth.
