How to Care for a Lisbon Lemon Tree: Tips and Tricks



Understanding Lisbon Lemon Trees in Arizona 

  • Climate Suitability: Lisbon lemon trees are well-adapted to Arizona’s hot, dry climate. They thrive in full sun and heat. 
  • Soil: Plant in well-draining soil. Arizona’s soil can be alkaline, so amending with compost or sulfur may be necessary to slightly lower the pH. 
  • Watering: Deep, infrequent watering is best. Allow the soil to dry out slightly between waterings. Overwatering is a widespread problem. 

Detailed Care Guide 

  • Planting: Choose a location with at least 6-8 hours of direct sunlight. Dig a hole twice as wide as the root ball. Plant at the same level as it was in the container. 
  • Fertilization: Fertilize with a citrus-specific fertilizer 3-4 times a year, following label instructions. 
  • Pruning: Prune lightly after fruiting to maintain shape and remove any dead, diseased, or crossing branches. 
  • Watering: Water deeply and less frequently. Check soil moisture before watering. A good rule of thumb in summer is to water to a depth of 2-3 feet, every 10-14 days (about 2 weeks). Adjust in cooler months. 
  • Mulch: Apply a layer of organic mulch around the tree to help retain moisture and suppress weeds. 

Common Problems and Solutions 

  • Yellowing leaves: May indicate overwatering, nutrient deficiency (iron or nitrogen are common), or citrus greening disease. Adjust watering as needed, fertilize, or contact a tree care professional if you suspect disease. 
  • Pests: Watch for aphids, scale, and whiteflies. Treat with insecticidal soap or neem oil. For severe infestations, consult a professional. 
  • Sunburn: Young trees can be susceptible. Provide shade during the hottest part of the day for newly planted trees.
