Suitable conditions for Planting Guava Trees

Guava is a round pear-shaped fruit commonly 2 to 3 inches long. Guava fruit can be green, yellow, red, purple, or black-skinned. The flesh can be white, coral, yellow,or red. Ripe guava fruit has sweet, moist flesh that is highly scented. Each guava fruit has several small, hard, but edible seeds.
Ripe guava can be halved and eaten from the shell or sliced and combined with other guava fruit. Guava can be pureed and made into sorbets, sauces, and mousses, or cooked down into a firm paste and sliced. Dwarf Guava plants can be made into jellies, jams, and preserves.  

Hybrid Guava plants can be planted at virtually any time of year in tropical zones, but do best in the warmer months. Early spring, when it’s just starting to warm up, is a good time, as it gives the tree time to stretch out its roots underground before warm sets in.
If you’ll be growing your guava fruit tree in a container and bringing it indoors for the winter, you can start anytime provided that the conditions are relatively warm. Aim for temperatures that are above 45 degrees, and preferably above 50 degrees.

While you’ll need to make sure your guava tree has full sun and another tree for pollination purposes, you’ll also need to keep them separate. Guava plants should be placed at least 10 meters about 33 feet apart when possible but can be as close as 5 meters if necessary.
Place your guava fruit trees in sunny, well-lit locations as they require full sun. Provide a place that is at least somewhat protected from wind if possible, whether by fencing for windbreak. Your small guava tree should need that protection to develop, and older trees can be sensitive to cold winds too.
Guavas can be planted as especially trees on cordons. However, don’t place other guava plants beneath them, as exudates from their root system tend to kill off weeds or other plants at the tree’s base.
