Sunlight: Plant in full sun for optimal growth and fruit production. Ensure the tree receives at least 6-8 hours of direct sunlight per day.
Soil: Oroblanco trees prefer well-draining, sandy loam soil but can adapt to various soil types. Ensure that the soil drains well to prevent root rot.
Watering: Water regularly, especially during the growing season. However, be careful not to overwater as this can lead to root problems. Let the top inch of soil dry out between waterings.
Fertilization: Feed the tree with a citrus-specific fertilizer during the growing season. Apply a balanced fertilizer (higher in nitrogen) in early spring, followed by regular feedings through the summer to encourage healthy growth and fruit development.
Pruning: Prune in late winter or early spring to remove dead or damaged branches and to maintain the tree's shape. Proper pruning improves air circulation and encourages fruit production.
Mulching: Apply a layer of mulch around the base of the tree to help retain moisture, suppress weeds, and regulate soil temperature.
Cold Protection: In areas prone to frost, consider protecting the tree with frost blankets or by bringing container-grown trees indoors during cold spells.
