Water deeply once or twice a week, allowing the top inch of soil to dry between waterings. Prune in late winter or early spring to remove dead or overcrowded branches, encouraging better airflow and fruit production. Keep an eye out for pests like aphids, spider mites, and scale insects, treating infestations with neem oil or insecticidal soap.

Lemon trees can be grown from seed, but they may take 3–6 years to produce fruit. Extract seeds from a fresh lemon, rinse off pulp, and soak them in water for 24 hours. Plant seeds ½ inch deep in well-draining potting mix, keeping the soil moist and warm (70–80°F or 21–27°C). Germination usually takes 2–4 weeks, and seedlings should be transplanted into larger pots once they develop several sets of true leaves.

Lemon trees thrive in well-draining, sandy or loamy soil with a pH of 5.5–6.5 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 protected from strong winds. For container growing, use a 10–15 gallon pot with drainage holes, as lemon trees adapt well to indoor and outdoor environments.

Lemon trees require regular feeding with a citrus-specific fertilizer high in nitrogen (such as 6-3-3 or 8-4-6) every 4–6 weeks during the growing season. Supplement with micronutrients like iron, magnesium, and zinc to promote healthy growth. Adding compost or organic matter helps maintain soil fertility.

Lemon trees are sensitive to frost and need protection in temperatures below 40°F (4°C). For in-ground trees, cover them with frost blankets and mulch around the base. If grown in a pot, move indoors near a bright window during winter and reduce watering to prevent root rot.

Lemons typically take 6–9 months to ripen, depending on the variety. The fruit is ready when it turns fully yellow and feels slightly soft when gently squeezed. Handpick lemons to avoid damaging branches. Regular pruning in late winter helps maintain tree shape, improves air circulation, and enhances fruit production.
