The real guava (Psidium), also known as Brazilian or pineapple guava, comes from the tropical and subtropical regions of Central and South America. The shrub or tree, up to two meters high, requires a lot of sun and warmth, but also adapts quite well to the Central European climate. The plant is only not frost hardy, which is why it should not overwinter outdoors. With a bit of luck you can even harvest ripe fruit.
How do I properly care for a guava plant?
Guava care includes a sunny location, well-drained substrate, regular watering, weekly fertilization during the vegetation phase, pruning if necessary and a cool winter at 10-15 °C. Cuttings or seeds are suitable for propagation.
What location does the guava need?
As tropical plants, guavas like both the sun and the warmth, they can't get enough of both. So treat your guava to a sunny and wind-protected spot in the garden or on the balcony. A bright location in the winter garden with temperatures of up to 30 °C is also ideal.
In which substrate does the guava feel particularly comfortable?
Guavas do not place any special demands on the substrate. It should just be loose and well-drained. Good drainage is also important to avoid waterlogging.
How often should you water the guava?
The plant needs a lot of water and should never dry out. Check with your fingers whether it is time to water again: If the substrate has dried on the surface, you should water.
When and with what should you fertilize the guava?
Fertilize the guava weekly during the growing season with a liquid complete fertilizer (€18.00 at Amazon). There is no fertilization in winter.
Can you cut the guava?
Pruning is usually not necessary; only excessively long shoots should be shortened after the eventual harvest. Dead wood or shoots that are too close together or that cross each other must also be removed regularly.
How to propagate guava?
Guavas can be propagated very well from cuttings. But you can also grow them from seeds (purchased or collected yourself). Cut the cuttings in spring.
Which diseases and pests are typical for the guava?
Due guava is quite robust; infestation by pests, fungi or other pathogens is rare. Only too much moisture or even waterlogging leads to rot.
Is the guava hardy?
As a tropical plant, the guava is not hardy and should be overwintered cool at around 10 to 15 °C in a bright room.
Tip
In order to be able to harvest fruit, you have to help a little with the pollination with the brush.
