Origin
The guava originated in the American tropics, probably in Central America. It was widely distributed prior to the arrival of the Europeans. ⁵

The Glorious Guava, History of the guava, Edible South Florida

Description
The common guava is easy to grow and tolerates adverse conditions. The tree is attractive and the patchy bark lends visual interest. It bears prolific quantities of fruit. The aromatic fruit is well regarded throughout the American tropics and beyond. Unfortunately, the guava is a primary host of the Caribbean fruit fly. In addition, it is classified as an invasive exotic. When making planting decisions, the gardener should weigh these two drawbacks against the guava's many attributes. ⁵

Leaves
Leaves opposite, simple; stipules absent, petiole short, 3-10 mm long; blade oblong to elliptic, 5-15 x 4-6 cm, apex obtuse to bluntly acuminate, base rounded to subcuneate, margins entire, somewhat thick and leathery, dull grey to yellow-green above, slightly downy below, veins prominent, gland dotted. ⁴
Crushed leaves are aromatic.

Fig. 9. Leafbud of common guava (P. guajava), Burdwan, West Bengal, India

Flowers
White, about 1 inch (2.54 cm) in diameter, borne singly or in small groups (cymes) in axils of leaves of recent growth. ¹
Flowers are produced on branchlets of recent growth, and are an inch broad, white, solitary, or several together upon a slender peduncle. The calyx splits into irregular segments; the four petals are oval, delicate in texture. In the center of the flower is a brush-like cluster of long stamens. ³
One of the most critical botanical characteristics of guava is that flowers are borne on newly emerging lateral shoots, irrespective of the time of year. ⁴

Fig. 17. P. guajana flower habit

Fruit
A berry with few to many small brown seeds. Fruit shape ranges from round, ovoid to pear-shaped. Fruit weight ranges from 1 ounce to 48 ounces (28 g - 1.4 kg). The peel color ranges from green to yellow and flesh color may be white, yellow, pink or red. Fruit peel thickness may be thin or thick and depends upon cultivar. There is a wide range in flavor and aroma, ranging from sweet to highly acid and strong and penetrating aroma to mild and pleasant. ¹
When immature and until a very short time before ripening, the fruit is green, hard, gummy within and very astringent.
Fruits are borne by new shoots from mature wood. If trees bear too heavily, the branches may break. Therefore, thinning is recommended and results in larger fruits. The fruit matures 90 to 150 days after flowering. ²
The white fleshed varieties tend to be slightly more acid than the pink or dark colored varieties. ⁶

South Florida Harvest Calendar, Fresh from Florida

Varieties Page

Harvesting
Guava trees generally begin fruit production 3 to 4 years after planting and yields range from 50 to 80 lbs (23-36 kg) or more per tree per year. In Florida, guava may produce two crops per year; the main crop during summer followed by another smaller crop during early spring. However, through simple pruning techniques fruit may be produced nearly year-round. ¹

Pollination
Self-pollination is possible but cross-pollination by insects results in higher yields. ¹
The chief pollinator of guavas is the honeybee (Apis mellifera). The amount of cross-pollination ranges from 25.7 to 41.3%. ²
The pollen is viable for up to 42 hours and the stigmas are receptive for about 2 days. ⁴

Propagation
Guava seeds remain viable for many months. They often germinate in 2 to 3 weeks but may take as long as 8 weeks. Pretreatment with sulfuric acid, or boiling for 5 minutes, or soaking for 2 weeks, will hasten germination. Seedlings are transplanted when 2 to 30 in (5-75 cm) high and set out in the field when 1 or 2 years old. Inasmuch as guava trees cannot be depended upon to come true from seed, vegetative propagation is widely practiced. ²
Veneer and cleft grafting and chip budding are more successful on young vigorous seedling rootstocks. Scion material should be from terminal stem growth which is still green and quadrangular. ¹
Seedlings may flower within 2 years; clonally propagated trees often begin to bear during the first year after planting. Trees reach full bearing after 5- 8 years, depending on growing conditions and spacing. ⁴
A simple method of propagation, which may be employed when it is desired to obtain a limited number of plants from a bush producing fruits of particularly choice quality, is as follows: With a sharp spade cut into the soil two or three feet from the tree, severing the roots which extend outward from the trunk. Sprouts will soon make their appearance. When they are of suitable size they may be transplanted to permanent positions. They will, of course, reproduce the parent variety as faithfully as a bud or graft. ³

Planting
In general, guava trees should be planted in full sun for best growth and fruit production. Select a part of the landscape away from other trees, buildings and structures, and power lines. Remember guava trees can grow to 20 ft (6.1 m) in height if not pruned to contain their size. Select the warmest area of the landscape that does not flood (or remain wet) after typical summer rainfall events. ¹

Cold tolerance
Trees will be injured by cold weather and will freeze at about 28 degrees F but will come back from the lower portions once the damaged areas are pruned out. ⁶

Pruning
Trees that are bearing fruit may be kept small (3 to 6 ft high) through continuous selective pruning and tipping or allowed to grow into slightly larger trees (6 to 12 ft). ¹

Pruning the guava tree ^v1

Off-season fruit production
Pruning may be used to induce off-season flowering and fruit production. Guava trees flower on new succulent, vigorous new growth arising from either lateral buds on older wood or at the ends of shoots. A period of 2–3 weeks without watering and then pruning will force new vegetative growth and flowering. Many times withholding water is not necessary. ¹

Fertilizing
In Florida, young guava trees should be fertilized every 1 to 2 months during the first year.
Fertilizer mixtures containing 6 to 10% nitrogen, 6 to 10% available phosphoric acid, 6 to 10% potash, and 4 to 6% magnesium give satisfactory results with young trees. For bearing trees potash should be increased to 9 to 15% and available phosphoric acid reduced to 2 to 4%. Examples of commonly available fertilizer mixes include 6-6-6-2 [6 (N)-6 (P2O5)-6 (K2O)-2 (Mg)] and 8-3-9-2 [8 (N)-3 (P2O5)-6 (K2O)-3 (Mg)]. ¹
From spring though summer, trees should receive 3 to 4 annual nutritional sprays of copper, zinc, manganese, and boron. ¹

Irrigation
Once guava trees are 2 or more years old irrigation will be beneficial to plant growth and crop yields during prolonged dry periods. The period from bloom and through fruit development is important and drought stress should be avoided at this time with periodic watering. ¹

Other Injuries
Some nutritional problems, particularly a lack of minor elements, often occur on highly alkaline soils and trees benefit from periodic applications of nutritional sprays. ⁶

Food Uses
Raw guavas are eaten out-of-hand, but are preferred seeded and served sliced as dessert or in salads. More commonly, the fruit is cooked and cooking eliminates the strong odor. Bars of thick, rich guava paste and guava cheese are staple sweets, and guava jelly is almost universally marketed. It is made into syrup for use on waffles, ice cream, puddings and in milkshakes. Guava juice and nectar are among the numerous popular canned or bottled fruit beverages of the Caribbean area. There are innumerable recipes for utilizing guavas in pies, cakes, puddings, sauce, ice cream, jam, butter, marmalade, chutney, relish, catsup, and other products. ²

Medicinal Properties **
The roots, bark, leaves and immature fruits, because of their astringency, are commonly employed to halt gastroenteritis, diarrhea and dysentery, throughout the tropics. Crushed leaves are applied on wounds, ulcers and rheumatic places, and leaves are chewed to relieve toothache. The leaf decoction is taken as a remedy for coughs, throat and chest ailments, gargled to relieve oral ulcers and inflamed gums; and also taken as an emmenagogue and vermifuge, and treatment for leucorrhea. It has been effective in halting vomiting and diarrhea in cholera patients. It is also applied on skin diseases. A decoction of the new shoots is taken as a febrifuge. The leaf infusion is prescribed in India in cerebral ailments, nephritis and cachexia. An extract is given in epilepsy and chorea and a tincture is rubbed on the spine of children in convulsions. A combined decoction of leaves and bark is given to expel the placenta after childbirth. ²

Other Uses
The leaves and bark are rich in tannin (10% in the leaves on a dry weight basis, 11-30% in the bark). The bark is used in Central America for tanning hides. Malayans use the leaves with other plant materials to make a black dye for silk. In southeast Asia, the leaves are employed to give a black color to cotton; and in Indonesia, they serve to dye matting. ²

General
From the Greek psidion (pomegranate), due to a fancied resemblance between the two fruits. ⁴
Dehydrated guava juice powder was used as a source of vitamin C to fortify rations of Allied troops during the Second World War. ⁹
