When planting fruit, vegetables or herbs in your landscape, it is beneficial to plant complementary produce that can grow close to each other. An example of this is garlic and lemon trees. When planted by the base of lemon trees, garlic can help repel insects such as snails, aphids, moths and deer. Also, garlic has the natural fungicide sulfur that lemon trees will absorb through the roots, preventing disease such as mildew. When planting garlic by lemon trees that are already established, plant the cloves from March to April so they can develop in cooler soil. Also, choose garlic cloves to plant that are smooth and appear healthy from garlic bulbs.
Prepare the soil around the planting area under the lemon tree, as garlic needs loose, rich, loamy soil. It also needs generous amounts of fertilizer to grow, such as a 10-10-10 variety. Keep in mind that since the soil must be kept consistently moist, even ground would be easiest to grow garlic, and the planting spot must also be in full sun.
Dig a circular trench about 5 inches deep, at least 1 foot from the base of your lemon tree.
Create planting holes in the trench about 1 inch deep per clove, keeping the holes about 5 inches apart.
Plant one clove per hole with the end of the clove that was attached to the base pointing down. Cover the cloves with about 1 inch of soil and pat down.
Keep the soil regularly moist throughout the growing season, particularly once you see the leafy tops poking through the soil.
