Psidium Guajava

What is the plant

Guava fruit trees (Psidium guajava) are not a common sight in North America and need a decidedly tropical habitat. In the United States, they are found in Hawaii, the Virgin Islands, Florida and a few sheltered areas in California and Texas. The trees are very frost tender and will succumb to a freeze when young, although adult trees may survive short periods of cold. That said, the plants are attractive and produce deliciously rich, sweet fruits that are excellent fresh or in desserts. Given enough guava tree information, it is possible to grow these small trees in a greenhouse or sunroom and reap the benefits of their Vitamin C-rich fruits.

How to Care for the Plant

Water
On sandy, well-drained soil, you may need to water twice a week. for soils that hold moisture, such as heavier clay soils, or loamy soils rich in organic matter, watering once a week is fine, soil covered by mulch will retain water better, and you may need to water less often.
Pruning
It is important because damaged leaves and stems can actually be an energy drain on your plant. By removing those dead parts, you're taking some of that work off your plant’s plate and allowing it to divert its energy into healthy leaves and new growth!
Fertilizer
When it comes to fertilizers, you want to avoid over-fertilizing (just like an overdose of vitamins isn't great for us, either). Less is more, so it’s important to follow what the package says for application amounts.

Sunlight
They do not like full sun and many of them will become very damaged or will not survive very long when they receive too much direct sunlight. Instead, expose them to indirect, filtered sunlight.
Soil
Prefer fertile soil, preferably loose and loamy with adequate drainage.
Temperature
The optimum temperature for germination of guavas falls in the range of 68 to 82 F (20 to 28 C). In winters, the temperature must not fall below 27 F (-3 C) for young guava trees. Mature guava tree (at least 3 years old) can bear temperature down to 20 F (-6 C). Remember, guavas are not frost tolerant, especially young plants, so if in a climate where the temperature falls below the range given here then it is better to keep the plant indoors until the temperature rises up.

Container
When choosing a pot, choose a pot that is 2.5-5 cm (1-2”) larger than the current size. Ceramic pots are porous which means your plants are less likely to experience root rot from overwatering. It also means you'll have to water more often. Plastic pots are lighter, less likely to break, and easier to clean.
