Garlic is a pungent root vegetable that can help repel insect pests when you grow it near plants that snails, slugs, aphids and other creatures like to eat. Garlic is said to benefit cucumbers, peas, celery lettuce and fruit trees. Its smell can keep away Japanese beetles, root maggots, codling moths and even deer. Garlic plants accumulate the natural fungicide sulfur, which nearby plants soak up through their roots, helping to prevent powdery mildew and other fungal diseases that can attack lemon trees.
Planting Garlic Near Lemon Trees
Dig a shallow circular trench at least 1 foot from the base of your lemon tree, making it about 4 inches deep.
Dig 1- or 2-gallon buckets full of organic compost or well-composted animal manure into your trench and then refill it with the soil or compost mixture you dug out.
Using your trowel, make one planting hole that's about 1 inch deep for each garlic clove you plan to grow. Leave 3 to 5 inches between holes.
Drop one garlic clove into each planting hole, making sure to plant them with the end that was attached to the base of the head pointing downward and the pointed end pointing upward.
Dig up your garlic in late summer or fall when the tops begin to turn yellow or brown and die back. Allow them to dry thoroughly in a warm, dark, dry, well-ventilated place. Then cut off the tops and store your garlic at about 32 degrees F. They will keep well for 6 or 7 months, so you can plant your own garlic the following spring.
