Origin
Psidium littorale Raddi var. longipes (Berg) Fosberg, commonly known as strawberry guava, is a species of small tree or shrub belonging to the Myrtaceae family. It is native to Brazil, but has become naturalized in many countries around the world, including Hawaii, Florida, and other parts of the Caribbean and Pacific islands.
Common Names
The plant is commonly known as strawberry guava, cherry guava, cattley guava, or Chinese guava.
Uses
The fruit of the strawberry guava is edible and often used in jams, jellies, and baked goods. The leaves and bark of the plant are also used in traditional medicine for their anti-inflammatory, antimicrobial, and analgesic properties. Oil extracted from the seed may have potential as a biodiesel fuel source, and the wood can be used for fuel or as a source of charcoal.
General Appearance
The strawberry guava plant is a small tree or shrub that can grow up to 6 meters tall. It has a smooth, grey-brown bark and dark green, glossy leaves that are fragrant when crushed. The plant produces white, pink or red flowers that are followed by small, round fruit that are yellow or reddish in color. The fruit is about 3-4 cm in diameter, with a sweet, tropical flavor and small seeds inside. The plant prefers well-drained soils and thrives in warm, humid climates.
Light Requirements
Psidium littorale Raddi var. longipes (Berg) Fosberg requires full sun exposure to thrive. It can tolerate some shade, but inadequate light can lead to reduced growth and poor fruit production. Therefore, it is best suited for planting in areas that receive at least six hours of direct sunlight daily.
Temperature Requirements
This plant can tolerate a wide range of temperatures, but it prefers warm and humid climates. The ideal temperature for growth ranges between 20 to 30 degrees Celsius, but it can withstand temperatures as low as 5 degrees Celsius. Temperatures below 5 degrees Celsius can damage the plant, especially in young plants.
Soil Requirements
The plant can grow in various soil types, including sandy, loamy, and clay soils. However, the best soil for optimal growth is well-draining, fertile soil with a pH range between 5.5 and 6.5. The soil should also be rich in organic matter, which helps improve soil structure and water holding capacity. Psidium littorale Raddi var. longipes (Berg) Fosberg is considered salt-tolerant and can grow in coastal areas with saline soils.
Cultivation Methods
Psidium littorale Raddi var. longipes (Berg) Fosberg is a tree that is well adapted to a wide range of soils, as long as it is well-drained. It can grow in sandy, loamy, or clay soils, but it prefers slightly acidic to neutral soil with a pH range of 5.5 to 7.5. The tree can thrive in full sun or partial shade and is tolerant of salt spray and coastal conditions.
The tree is propagated by seeds, which should be soaked in water for 24 hours to increase the germination rate. The seeds should be sown in well-draining soil and kept moist but not waterlogged. Germination can take up to three weeks, and the seedlings can be transplanted to their permanent location after six months.
Watering Needs
The Psidium littorale Raddi var. longipes (Berg) Fosberg tree has moderate water needs and should be watered regularly during the growing season, especially during dry periods. However, it is important not to overwater the tree, as it can lead to root rot and other fungal diseases. The soil should be allowed to dry slightly before watering again.
Fertilization
The Psidium littorale Raddi var. longipes (Berg) Fosberg tree requires regular fertilization to thrive and produce fruit. A balanced fertilizer with an N-P-K ratio of 8-8-8 or 10-10-10 should be applied every three months during the growing season. Organic fertilizers such as compost, manure, or fish emulsion can also be used to provide the tree with additional nutrients.
Pruning
Pruning is an essential part of caring for the Psidium littorale Raddi var. longipes (Berg) Fosberg tree. The tree should be pruned in late winter or early spring to remove any dead, diseased, or damaged branches. Pruning also helps to control the size and shape of the tree and improve air circulation and sunlight penetration.
Young trees should be trained to a single trunk to ensure a strong and stable structure. Once the tree reaches maturity, it should be pruned to maintain a compact shape and prevent it from becoming too tall or spindly. Fruit-bearing branches should be pruned to promote new growth and increase fruit production.
Propagation methods for Psidium littorale Raddi var. longipes (Berg) Fosberg
Psidium littorale Raddi var. longipes (Berg) Fosberg, commonly known as the strawberry guava, is a small tree or shrub that is native to several countries in South America. It is a highly invasive species and has become a major problem in many parts of the world. Propagation is an effective way to control the spread of this species and to promote the growth of desired plants. There are several methods of propagation that can be used for Psidium littorale Raddi var. longipes (Berg) Fosberg, some of which are described below.
Seed propagation
Seed propagation is the most common method of propagation for Psidium littorale Raddi var. longipes (Berg) Fosberg. The seeds of the strawberry guava are small and black, and they can be collected from ripe fruits. The seeds should be cleaned and planted immediately in a well-drained potting mix. The seedlings should be kept moist but not waterlogged, and they should be placed in a warm, bright location. After the seedlings have grown to about 10 cm in height, they can be transplanted to larger pots or directly into the soil.
Cuttings propagation
Cuttings propagation is another method that can be used for Psidium littorale Raddi var. longipes (Berg) Fosberg. Cuttings should be taken from mature, healthy plants and should be about 15 cm in length. The cuttings should be dipped in rooting hormone and planted in a well-drained potting mix. The cuttings should be kept moist but not waterlogged, and they should be placed in a warm, bright location. After the cuttings have developed roots and grown to about 10 cm in height, they can be transplanted to larger pots or directly into the soil.
Air layering propagation
Air layering propagation is a more complex method that can be used for Psidium littorale Raddi var. longipes (Berg) Fosberg. The branches of the plant should be selected, and a portion of the bark should be removed from the branch. A rooting hormone should be applied to the exposed portion of the branch, and the area should be covered with damp sphagnum moss and plastic wrap. After the roots have developed, the branch can be cut off from the parent plant and planted in a well-drained potting mix.
Overall, Psidium littorale Raddi var. longipes (Berg) Fosberg can be propagated using several methods, including seed propagation, cuttings propagation, and air layering propagation. Each of these methods has its pros and cons, and the choice of method will depend on the availability of plant material, time, and expertise.
Disease Management for Psidium littorale Raddi var. longipes (Berg) Fosberg
Psidium littorale Raddi var. longipes (Berg) Fosberg is relatively resistant to diseases. However, it can still be affected by a few diseases. Here are some common diseases and their management:

- Rust: It is a fungal disease that causes rust-colored pustules on leaves. To manage this disease, remove infected plant parts and destroy them. Also, maintain good air circulation and avoid overhead watering. If necessary, apply a fungicide.
- Powdery Mildew: It is a fungal disease that causes white powdery patches on leaves. To manage this disease, remove infected plant parts and destroy them. Also, maintain good air circulation and avoid overhead watering. If necessary, apply a fungicide.
Pest Management for Psidium littorale Raddi var. longipes (Berg) Fosberg
Psidium littorale Raddi var. longipes (Berg) Fosberg can be affected by a few pests. Here are some common pests and their management:
- Aphids: They are small, soft-bodied insects that suck sap from leaves and stems. To manage these pests, remove them by hand or spray them with water. If necessary, apply insecticidal soap or neem oil.
- Scale Insects: They are small, circular insects that suck sap from leaves and stems. To manage these pests, remove them by hand or dip a cotton swab in alcohol and apply it to each insect. If necessary, apply insecticidal soap or neem oil.
- Mealybugs: They are small, whitish insects that suck sap from leaves and stems. To manage these pests, remove them by hand or spray them with water. If necessary, apply insecticidal soap or neem oil.
