Planting Tips
Choose a location that receives full sun throughout the day.
Dig a planting hole twice as wide as the root ball but no deeper than the container. Position the tree so the top of the root ball sits slightly above the surrounding soil.
Water thoroughly after planting and apply 2–4 inches of organic mulch around the tree, keeping mulch several inches away from the trunk.
Young trees should receive regular irrigation during their first two years while becoming established.
Fertilizing
Feed Lisbon Lemon trees with a quality citrus fertilizer three to four times during the growing season.
Healthy soil is equally important. Adding compost and worm castings around the drip line improves soil biology, increases water-holding capacity, and provides slow-release nutrients that support healthy growth.
