Look for a fertilizer labeled for citrus trees with a ratio like 6-6-6 or 8-8-8 (Nitrogen-Phosphorus-Potassium).

Nitrogen promotes leaf growth, phosphorus encourages flowering, and potassium strengthens the fruit.

2. Fertilize According to Tree Age

Young Trees (1–3 years): Feed every 6–8 weeks during the growing season.

Mature Trees (4+ years): Feed 3–4 times per year, ideally in early spring, late spring, mid-summer, and early autumn.

3. Natural Boosters

Compost or well-rotted manure: Add a layer around the base to improve soil fertility.

Epsom salt: Provides magnesium for greener leaves and better fruit development.

Mulch: Keeps roots cool, retains moisture, and slowly adds nutrients.

4. Watering with Fertilizer
