Asimina triloba

The asimina triloba is a small fruit tree with deciduous leaves. The trees that have been planted for some years are very rustic, they are satisfied with the water provided by rainfall and do not need any kind of treatment. The specimens just placed at home, possibly at the beginning of autumn, need instead an initial watering, which must be repeated if the climate is particularly dry. They settle in autumn in order to have some fresh and humid months, which stimulate the development of the roots, thus avoiding that the greenery of the plant can create problems. During the spring and summer in general the Asimina triloba does not need watering, except in rare cases in which the rains are particularly hot. In particular the waterings supplied in the summer must not be excessive: the soil must have the possibility of drying to perfection between two irrigations.

Cultivate the asimina triloba

The asimina triloba is native to some states of the USA, where the climate is cool, and is perfectly suited to cultivation in Italy, in the family orchard, or even in city parks. They are low maintenance plants, which generally do not require pruning, except for the periodic removal of branches that can be damaged due to bad weather or accidental damage. The Asimina triloba can easily withstand the cold, and can withstand even prohibitive temperatures, with frosts that bring the thermometer well below zero. To grow to perfection, however, it needs to be placed in a slightly acid soil, and preferably watered with water that is not excessively full of limestone. The flowers are very particular and emit a bad smell, this because the pollination takes place by the work of carnaria flies. For this reason it is advisable to place the plants not too close to the houses.

Fertilize the Asimina

The fertilizations for these fruit trees must be supplied in autumn and late winter; slow release fertilizers are preferred, such as the complex granular fertilizer or pelleted manure. In this way the rains will allow it to dissolve, providing the plants with everything they need over the months. More than anything else they prefer slightly acid soils, which is difficult to find in many regions of Italy; they develop best in areas where camellias, azaleas and rhododendrons are widespread, such as near Lake Maggiore, where the soil is naturally acidic. In other conditions it is advisable to mix soil specific to acidophilic plants with the soil. also the supply of specific fertilizers, which increase the quantity of bio-iron available, is a healthy touch against the problems that can intervene due to the lack of this mineral.

Pests and diseases

Asimina triloba plants are grown in the garden, in all Italian regions; they love sunny positions, even if they bear the shadow without problems, provided you receive at least a few hours of direct sunlight every day. They are not attacked in a worrying way by pests or diseases, and generally there is a tendency to avoid any type of pesticide treatment. Generally the main problems are due to the climate or the terrain. In fact, cultivation in a poorly acidic soil can lead the plant to manifest ferric chlorosis: the foliage tends to turn yellow. To avoid this periodic supplies of chelated iron are generally more than sufficient. A very humid climate during the summer can hinder the formation of fruits, leading the plant to be totally unproductive for the current year.
