Guavas are tropical plants that produce sweet fruit that is high in vitamin C. Guava fruit is often made into jelly or preserves but can also be eaten fresh. Guavas can do well in a wide range of soils, but need protection for heavy frosts in northern and central California.
P. quajava crema
White flesh is succulent, sweet, and aromatic. Skin is light yellow, sometimes blushed with red.
P. quajava rosa
Pink flesh is smooth to grainy in texture, mild to sweet. Skin turns from green to yellow. Attractive green foliage. Very fragrant.
Mexican Cream (Tropical Yellow)
P. quajava Mexican Cream
Upright tree, originating from Mexico. Small to medium-small, roundish fruits. Skin light yellow, slightly blushed with red. Flesh creamy white, very sweet, fine-textured and excellent for dessert. Seed cavity small with relatively soft seeds.
P.quajava rojo malaysia
Red colored guava with pink-red flesh. This variety is unique not just for its fruit, but for its foliage also, which is tinted a deep red color. The flowers are bright pink. The Red Malaysian guava is often grown for ornamental purposes as well as fruit.
P. cattleianum lucidum
Yellow fruit, similar to the strawberry guava except fruits are often slightly larger (1-2"). Flesh is yellow, very fragrant, with the suggestion of a lemon-guava flavor. Small bush or tree to 20-25 feet, although often much smaller. The frilly white flowers are often borne a few times a year, concentrated during warmer months.
Guavas can be grown in containers or in the ground. They prefer well drained soils, but can thrive in a wide range of different soils types. They do best in soils with a pH of between 5 and 7. Soils that are high in salts can be problematic for guavas and should be avoided.
Guavas prefer regular deep root watering. Guavas can survive saturated soil conditions, but it is best to allow the soil to dry out somewhat between irrigations.
Guavas are amenable to pruning and shaping. They can tolerate heavy pruning and can also be trimmed to grow as hedges if desired. Remove all suckers and water shoots annually for best results. Guavas fruit on new growth, so pruning will not negatively affect fruit set.
In colder locations, prune as a shrub, rather than tree shape and mulch heavily to protect the stems from freezing.
Guavas are fast growing heavy feeders and can greatly benefit from regular feeding. Apply fruit tree fertilizers monthly, and especially just before heavy pruning.
Guavas need to be protected from freezing temperatures. Put Christmas lights on them or cover with a sheet, blanket or frost bag at night when you know the threat of frost is present.
Guavas can sometimes be bothered by typical fruit tree pests including mealybug, scale, or whitefly. Control of these pests can be achieved with a few applications of horticultural oil or insecticidal soap and regular pruning that keeps the guava plants open with good air flow. It may also be necessary to control ants that are crawling on the guavas. Boric Acid Ant Baits can be effective control.
