How to irrigate

The mannafin needs watering only during periods of aridity; if, on the other hand, the precipitations are abundant and frequent, the rainwater will be sufficient to satisfy the water needs of this tree. The soil must always be kept slightly moist, but it must never be completely impregnated: otherwise, there would be the risk of incurring annoying water stagnation and, consequently, rotting of the root system. Drip irrigation, also called sprinkling, is the ideal method, as it allows you to water the surface of the soil or the root area at your choice, and to supply water resources with prudence and moderation; a considerable saving is obtained with this system. The so-called drippers can be operated continuously or intermittently.

How to cultivate


This plant adapts to numerous types of soil and to even rather unfavorable conditions; however, it is advisable to follow some simple rules to grow it correctly. The planting of seedlings bought in the nursery must be carried out in autumn, in large and deep holes just over a meter; at the time of planting, a preliminary fertilization must also be applied. It is also suggested to use a brace for the first years of development, so that the tree grows straight, and to mulch the soil after planting to make it more fertile. Pruning can be aimed both at outlining the shape of the plant and at maintaining it; in the first case the cuts can be relatively abundant, in the second one must limit oneself to removing the diseased or dry branches.

Fertilization


The manure can be fertilized in spring or autumn, using organic substances such as mature manure; if the soil is lacking in fundamental elements such as potassium, phosphorus and nitrogen, the fertilizer used must provide them. Otherwise, the plant would tend to grow slowly and gradually weaken, and there would also be the risk of leaf chlorosis. Potassium is a necessary support for the absorption of sugars and for protein synthesis; phosphorus is essential for the roots to become stronger and for the metabolism to take place correctly; nitrogen provides for the development of tissues and guarantees an adequate presence of chlorophyll in the foliage. It is suggested to use fertilizers in which secondary elements are also included,

Manna ash: Exposure, diseases and remedies


The ideal exposure is sunny and bright, but sheltered from intense winds: the latter are dangerous especially for the younger specimens, and could easily damage them. Furthermore, the plant tolerates high temperatures better, as long as they are not excessive, compared to low ones. Among the fungal diseases that can affect this tree there is powdery mildew, or albugine, which manifests itself as a sort of white mold and causes the deterioration of leaves, shoots and fruits; for the cure we recommend treatments with sulfur-based fungicide products. Wood decay is also caused by fungi, and leads to the formation of cracks, splits or swellings on the trunk and branches: it is essential to immediately eliminate the attacked parts to avoid the spread of the disease, and to disinfect the wounds immediately.
