How to grow the Guava plant


Guava plant, among the most interesting fruit plants we also find the one that takes the name of Guajava, but more often we are used to hearing about it with the name of guava. The guava is a fruit tree that has a typically American origin (especially from the central and southern parts), whose cultivation is widespread in most of the tropical areas of the planet.

In the world, two species of guava are cultivated in most cases, with the respective cultivars that have developed over time: it is the Psidium guajava, which is also called the true guava, while the second species is Psidium littorale, which has small dimensions.

Considered in nature, this fruit tree has quite large dimensions which, over the years, can reach a maximum of 7-10 meters in height. In the Italian territory, compact cultivars are grown in most cases and, despite everything, all those guava trees that do not go beyond 3-4 meters in height are chosen.

These trees, despite being exotic, are part of the Myrtaceae family, particularly widespread in Italy: they are evergreen trees, with large leathery leaves, with a dark green color. During the spring season, these trees have the characteristic of producing large flowers with a candid color.

After flowering, it is the turn of the production of fruits, which have a decidedly rounded shape, with dimensions that are very reminiscent of those of a lemon or an orange.

Guava fruits are traditionally consumed in South America, but also in Asia and in the northern part of the African continent.

The fruits of the guava tree have a rather sour taste and can be more or less sweet depending on the species or variety that is being considered.

The guava fruits, in most cases, are destined for other sectors: in fact, they are used for the production of jellies, juices, jams, which are made with great simplicity due to the high quantity of pectin that is present in the fruits. of guava.

The latter is characterized by containing a good amount of mineral salts, vitamin C, and a rather limited number of calories.


The cultivation of guava is also carried out within the Italian territory, especially in all those areas where citrus fruits are grown, such as the Sicily region.

In all coastal areas that have a mild winter climate, the guava tree can also be safely placed in the garden: indeed, quite frequently this tree is also cultivated within areas that have a slightly more stiff winter climate since it can be easily placed in a vase, where it manages to keep small dimensions, which never go beyond two meters.

This explains the reason, in the latter case, the vase can be moved without problems to a place that is protected against winter frosts.

In fact, the guava tree is characterized by being able to withstand the cold without particular complications, even if it suffers greatly from intense and continuous frost: this explains the reason why, placing it during the winter season in a cold greenhouse or on a terrace, it may be the most suitable solution for those who grow guava in Italy.

The guava, as we have been able to see, can also grow without problems as a houseplant: all the specimens that are not then in contact with the cool winter climate have the particularity of producing a reduced quantity of fruit.


The guava, in most cases, is multiplied by seed, but there is also an alternative, represented by the agamic way (that is, to be chosen between different systems, including rooted sucker, cutting, grafting, and layering.

The plants that are obtained from the multiplication of the guava, therefore, are planted with sixths that have specific dimensions (4-5 x 5-6 meters) and can last up to fifteen or twenty years.

The pruning of the guava must be carried out with particular and specific limitations, both as regards the years of the formation of the plant and in the period in which the fruits are produced.


The fertilization of the guava plant should correspond to approximately 100-200 grams of nitrogen for each plant and 50-100 grams of phosphorus and potassium.

We must not forget how the guava plant needs to receive constant irrigation when it is grown within subtropical areas.

The ripening of the fruits of the guava plant takes place both on the plant and between different plants (in Sicily this period is between the last days of October until the middle of December, approximately).

On the Italian territory, cultivated plants do not have to face a large number of adversities. In all places of origin, guava plants, on the other hand, have to face the attacks of various parasites, but which can be prevented with the necessary attention.
