Establishment
3-6 monthsYoung tree with limited branching; new growth is soft and tender; developing root system
Water regularly and keep soil moist; protect from wind and intense sun; avoid fertilizing immediately after planting; stake if necessary for support
Vegetative Growth
1-2 yearsIncreasing branch development; dense foliage; tree doubles in size; no flowers yet or minimal flowering
Prune to shape canopy; fertilize monthly with citrus fertilizer during growing season; maintain consistent watering; monitor for pests
Flowering
2-4 weeks per flush; multiple flushes possible annuallyFragrant white and pink-tinged flowers appear; typically in spring but can occur throughout year in warm climates; flowers appear singly or in clusters
Reduce nitrogen fertilizer to encourage flowering; maintain regular watering; do not over-prune; ensure good air circulation; hand-pollinate if few pollinators present
Fruiting & Development
3-4 monthsSmall green fruits develop from flowers; gradually enlarge and change color; thin young fruit if overcrowded
Thin fruit to 1 every 6 inches for larger, higher-quality fruit; provide balanced fertilizer; maintain consistent watering to prevent fruit drop; spray for pests as needed
Harvest-Ready
Variable; fruits can stay on tree 2-4 weeks at peak ripenessFruits reach full size (1.5-2 inches diameter); color transitions from green to yellow-lime blend; fragrant and slightly soft to gentle pressure
Monitor maturity; harvest when color develops and fruit yields slightly to pressure; store at room temperature or refrigerate; can leave on tree for extended harvest window

Harvest Tips
Harvest when fruits develop yellow-green color and yield slightly to gentle pressure; cut with pruning shears rather than pulling to avoid damaging branches; most productive in late winter through spring, though can fruit year-round in tropical zones; leave some fruit on tree to continue ripening; fruits can hang on tree for 2-4 weeks at peak flavor; store at room temperature for 1-2 weeks or refrigerate for up to 3 weeks
Fun Facts
- 🌱 Lemon Lime is likely a hybrid between a lemon and a Persian lime, combining the tartness of lemon with the subtle sweetness and aroma of lime—creating a unique flavor profile not found in either parent species.
- 🌱 Citrus trees can have multiple flushes of flowers per year in tropical and subtropical regions, meaning a single tree can produce fruits at different stages of ripeness simultaneously.
- 🌱 The fragrant white flowers of citrus trees are highly attractive to bees and other pollinators, and are sometimes used to make citrus flower water (neroli oil) valued in perfumery and cooking.
