Can you grow a Lemon Tree in Oklahoma? Growing a lemon tree in Oklahoma can present certain challenges, but it can be done if the proper conditions are created. Although lemon trees bear fragrant, attractive white flowers and attractive glossy green leaves, they can be temperamental and finicky, especially if the weather conditions in Oklahoma are unpredictable. The key to successfully growing lemon trees in Oklahoma is to choose a variety that is suited to the extreme weather in the area, to create a climate-controlled environment and to regularly fertilize and prune the trees.
Site and Soil Selection
The site and soil selection are both important considerations when planting a lemon tree in Oklahoma. Lemon trees need an area with full sun exposure, with temperatures that remain relatively consistent throughout the year. The soil should be well-draining and not necessarily rich in nutrients. Lemon trees typically prefer sandy, loamy soils, with a 6.0 to 8.0 pH range.
Varieties
Selecting a variety of lemon tree that is suited for Oklahoma weather is essential for successful growth. Meyer Lemon is the most popular choice for Oklahoma and is generally the hardiest with the greatest cold tolerance. While Meyer Lemon prefers environments with higher humidity, it is able to tolerate extreme weather and temperatures that drop to 20°F.
Climate Control
Climate control is a valuable tool for successful lemon tree growth in Oklahoma, especially during the harsher winter months. Establishing a greenhouse or using a wind barrier can protect the tree from wind fluctuations and severe weather. The wind barrier must be removed when the temperature is warm enough to allow fruiting and flower production.
Fertilization and Pruning
Lemon trees need regular fertilization to keep growing and producing. Organic options such as compost and synthetic liquid or granular fertilizers can be used. Pruning is important to maintain the shape of the tree and reduce the risk of powdery mildew. Prune the branches and remove any dead or diseased foliage.
Covering Trees in Cold Weather
When temperatures in Oklahoma drop, the lemon trees should be covered with a protectant cloth or frost blanket for extra protection. The blanket should be placed over the tree during the coldest months of the year and removed when the temperature rises. It is especially important to keep Japanese and Eureka lemons covered during the winter months.
Irrigation
Irrigation is necessary for a successful lemon tree growth. It is recommended to thoroughly water the soil around the tree twice per week at the base of the tree, making sure that the soil is completely soaked. The frequency of irrigation may need to be increased or decreased depending on the weather conditions in Oklahoma.
Pest and Disease Control
Inspect the tree regularly for pests and diseases. Aphids, whiteflies, mites, and snails can be removed with a spray of neem oil or horticultural soap. If the tree is infected with a disease, use the appropriate biofungicides to stop the spread of the disease.
