Growth Stages

1

Establishment (Year 1)

12 months

Young tree focuses on root and canopy development with minimal flowering

Water deeply and frequently; apply mulch 3-4 inches from trunk; protect from wind; avoid heavy pruning; apply balanced fertilizer monthly during growing season

2

Vegetative Growth (Years 2-3)

24 months

Tree develops strong scaffold branches and fuller canopy; light flowering may appear

Continue regular watering and feeding; prune to establish open vase structure; remove any fruit that sets to conserve energy; thin overcrowded branches

3

Flowering (Spring/Early Summer)

4-6 weeks

Abundant fragrant white flowers appear in clusters on branch tips and terminals

Maintain consistent watering during flower set; avoid heavy nitrogen fertilizers which reduce flowering; do not prune during flowering; monitor for pest activity

4

Fruit Development (Summer to Fall)

3-4 months

Small green fruits develop from pollinated flowers; fruit gradually enlarges and changes color to light yellow-green

Thin fruit to 6-8 inches apart for larger individual fruits; continue regular deep watering; provide citrus fertilizer with higher potassium; control pests that damage developing fruit

5

Fruit Maturity & Harvest (Fall to Winter)

6-8 weeks

Fruit reaches full size and develops characteristic sweet flavor; skin color ranges from light green to pale yellow

Ensure adequate water to maintain fruit quality; harvest when fruit yields slightly to pressure; handle carefully to avoid bruising; can leave ripe fruit on tree for extended storage

Harvest Tips

Fruit is typically ready to harvest 12-16 weeks after flowering. Pick when fruit is slightly soft to gentle pressure and has light yellow-green color.

Can be left on tree for several weeks after maturity. Wash before eating or juicing.
