It looks like you might be referring to Aadu plants, which is another name for guava (Psidium guajava), commonly used in some regions. Here’s a guide to growing and caring for guava plants:

Characteristics of Guava Plants

1. Size and Growth Habit: Guava trees are typically small to medium-sized, growing 10-30 feet (3-9 meters) tall. They have a rounded, dense canopy and a spreading habit.

2. Leaves: The leaves are evergreen, oval or elliptical, and can be 2-6 inches (5-15 cm) long. They are typically dark green and have a fragrant aroma when crushed.

3. Flowers: Guava plants produce small, white or pink flowers with multiple stamens. The flowers are usually solitary or in small clusters and have a pleasant fragrance.

4. Fruit: Guava fruit is round to oval and can range in color from green to yellow, pink, or red when ripe, depending on the variety. The flesh is juicy and aromatic with a flavor that can be sweet or tangy. Guavas contain numerous small, edible seeds.

5. Lifespan: Guava trees can live and produce fruit for several decades. They generally start fruiting within 2-3 years of planting.

Growing Conditions

1. Climate: Guava trees thrive in tropical and subtropical climates with warm temperatures and high humidity. They are sensitive to frost and cold temperatures.

2. Soil: Guavas prefer well-draining soils with good fertility. They grow best in sandy loam or loamy soils with a slightly acidic to neutral pH (pH 5.5-7.0). They can tolerate a range of soil types as long as drainage is adequate.

3. Sunlight: Full sun is essential for guava trees. They need at least 6-8 hours of direct sunlight per day to ensure healthy growth and fruit production.
