Fertilization Tips

Proper fertilization improves fruit size and sweetness, especially for guava tissue culture plants, which are known for their uniformity and high productivity.

Watering Requirements

• Water deeply once or twice a week, depending on climate and soil type.

• Avoid waterlogging; guava roots dislike soggy conditions.

Sunlight Needs

• L-49 guava trees require full sunlight for at least 6–8 hours daily.

• If grown in containers, rotate them occasionally for even sun exposure.

• Provide partial shade in extreme heat to avoid sunburn on fruit and leaves.

Pest & Disease Management

• Common pests: fruit flies, mealybugs, aphids.

• Diseases: anthracnose, wilt, and powdery mildew.

• Use neem oil, insecticidal soap, or approved fungicides as needed.

• Maintain good air circulation and prune dead or diseased branches.
