Water deeply once or twice a week, allowing the soil to dry slightly between waterings to prevent root rot. Prune in late winter or early spring to remove dead branches and promote better fruiting. Monitor for common pests such as aphids, spider mites, and citrus leaf miners, using neem oil or insecticidal soap if needed.

Lime trees can be grown from seed, but they take 4–6 years to bear fruit and may not grow true to type. Extract seeds from a fresh lime, rinse off any pulp, and soak them in water for 24 hours. Plant seeds ½ inch deep in well-draining soil, keeping the soil moist and warm (70–85°F or 21–29°C). Germination usually occurs within 2–4 weeks, and seedlings should be transplanted into larger pots once they develop several sets of true leaves.

Lime trees require well-draining, sandy or loamy soil with a pH of 6.0–6.5 and need full sun for at least 6–8 hours daily. If planting in the ground, space trees 12–15 feet apart in a location with good air circulation. For container growing, use a 10–15 gallon pot with drainage holes, and ensure it receives ample sunlight.

Lime trees need regular feeding with a citrus-specific fertilizer rich in nitrogen (such as 8-3-9 or 6-4-6) every 4–6 weeks during the growing season. Micronutrients like magnesium, zinc, and iron are also important for healthy growth. Adding compost or organic mulch helps retain moisture and enrich the soil.

Lime trees are cold-sensitive and should be protected when temperatures drop below 40°F (4°C). For in-ground trees, apply mulch around the base and cover with frost blankets. If growing in a container, move the tree indoors near a bright window during winter and reduce watering.

Limes take 6–9 months to ripen, depending on the variety. They are ready to harvest when they turn slightly soft and develop a glossy green or yellowish hue. Twist the fruit gently or cut with pruning shears to avoid damaging the tree. Annual pruning helps maintain shape, improve airflow, and encourage healthy fruit production.
