Water the newly planted tree every other day for the first week or so, then one to two times a week for the first two months. Continue watering young trees as needed during prolonged dry periods. Deliver water directly to the root zone rather than using an overhead sprayer. Mature trees rarely need supplemental watering. Lemon trees are heavy feeders, so they require thoughtful fertilization. After planting a lemon tree, apply about ¼ pound of fertilizer labeled for citrus trees. Repeat every three to four months for the first year. Mature trees usually require three to four pounds of fertilizer formulated for citrus trees two to three times a year. Protect a lemon tree from injury by maintaining a grass-free area 2 to 5 feet around the trunk. Spread a 2-inch-thick layer of mulch around the tree to help retain soil moisture and reduce weed competition. A lemon tree requires minimal pruning. Snip away water sprouts (vigorously growing shoots) and dead wood, then shape the tree as desired.
Harvest Tips
It takes about three years for a lemon tree to begin to produce fruit. The amount of fruit produced increases as the tree ages. Lemons are ready to harvest when the fruit is about 1½ to 2 inches in diameter and the peel is light green or yellow in color. A single tree might display fruit at different stages of development, but only harvest mature fruit. Pale green lemons will continue to ripen and turn yellow for a few weeks when stored at room temperature. You can also cure them for long-term storage by allowing them to sit in a cool, dry place and let them slowly yellow. As the rinds (which contain oil glands) turn yellow, they will become smooth and the fruit’s juice content will increase. Store in the refrigerator after curing.
