Origins and characteristics of guava
Guava (Psidium guajava) grows spontaneously in the Caribbean and Central America. It is the most cultivated species for export and marketed today. We recognize it thanks to its dense and persistent crown shape, which does not exceed 10 meters high. But to facilitate the harvest, we prefer to grow it in a low bush.
It adapts to the climate of our southern regions, provided it is protected in winter. The guava tree does not tolerate prolonged frost periods as well as long periods of winter drought. In the rest of France, we must grow it indoors. This is the case of the Montevideo guava (feijoa).
In the south of France, setting up the guava (Psidium guajava) takes place in April-May, as for the mango. The soil should be turned deep to facilitate the installation of the roots. We add a little organic fertilizer (manure). After having wedged the root ball of the tree, the gaps are filled with soil. You have to water very regularly to encourage recovery. Guava plants support all types of soil, whether heavy, light, acidic or basic.
Choose a sunny or slightly shaded location, in front of a south-facing wall.
Guava can also be planted in a pot. It then produces fruit the same size as a tree planted in the ground. For a pot planting, use an earthen pot with a fairly rich potting mix, to mix with sand and compost. For the soil to be well drained, consider installing clay balls at the bottom of the pot, about 20cm thick.
To fruit abundantly, guava (Psidium guajava) should be pruned in the spring. This light pruning involves removing the twigs that leave the trunk before the first branches. It applies to other tropical trees, such as papaya. In the bad season, cover the branches with a winter veil.
Bring organic matter to your guava tree each fall to maintain the soil's fertility level. For potted guava trees, use a fruit tree fertilizer in spring and summer. Fertilize once a month in the spring, twice a month during the summer season.
To avoid powdery mildew, avoid letting water stagnate in the saucer. Wait for the soil to dry before watering the guava tree. For potted guava trees, continue to water even in winter.
Diseases and pests of guava
Yes your guava tree lack of water, this can cause a delay in flowering or cause the fruit to fall.
The most common pests are aphids, mealybugs and mites, especially if your guava tree is in the greenhouse. Treat with black soap or insecticide.
The guava is harvested in autumn. Round in shape, it has light green skin which hides a red, pink or white heart. The flesh has aromas of strawberry and pineapple.
It is richer in vitamin C than oranges and kiwis. It contains 250 mg per 100g of fruit. The guava also provides trace elements (iron, zinc, copper). Highly dosed with soluble fibers, it gently stimulates intestinal transit.
Depending on the variety, it can be 2cm in diameter (like guava-strawberry) up to 15cm in the speciesPsidium guajava.
They can be stored after harvesting between 2 to 5 weeks, if the fruits are picked green.
