Elm tree

How much and when to irrigate

The elm is a plant belonging to the genus Ulmus and is distinguished from other plants because it is one of the most impressive. The characteristics of this plant certainly make it one of the most particular to cultivate and care for. Furthermore, the elm tree stands out for its versatility and adaptability, characteristics that certainly make it suitable for living in the most diverse environments. Normally, the day before planting, the soil is humidified. This will be irrigated but not excessively. This operation is of fundamental importance as it must produce a well-hydrated environment, suitable for accommodating the tree. However, the soil will continue to be irrigated in the days following the planting and, in general, during the first year of the plant's life cycle it is necessary to proceed on a regular basis.

How to cultivate it

To make a perfect plantation it is necessary to follow a series of precautions, valid also for the elm bonsai. First of all, we need to understand if the soil has all the morphological and physical characteristics suitable for optimal plant growth. Having ensured this, a hole is formed in the ground where the plant will be placed. Once filled with all the roots of the plant, it is covered with soil and then a proper protection is created against frost with straw or similar material. Planting is usually done in the autumn season, at temperatures that are still tolerable. Furthermore, the shrub is kept straight thanks to the use of a support to which it is tied. Pruning should not be carried out regularly.

How and when to fertilize

In the period immediately following the planting operation, in general all the operations that will allow the tree to adapt to the new living environment are developed. However, taking care of the elm implies a constancy that is not limited only to the post-cultivation period. Fertilization is the basic phase for the correct growth of the plant. We proceed with this fundamental operation during the spring and autumn months, that is in full vegetative season. The fertilization must obviously be a controlled activity, since an excess in the use of fertilizers can negatively influence the condition of the tree. Furthermore, it is recommended to use slow release fertilizers, both natural (such as manure or other animal waste) and chemicals.

Olmo: Diseases and treatments

The elm is a plant species continuously exposed to the attack of parasites and pathogens. The first disease certainly worthy of note is called graphiosis. This is one of the most fearful for this shrub and is due to a very dangerous parasite. To avoid the disease, the main thing to do is to eliminate the dry branches of the plant during planting. At worst, if not treated properly, the plant can even die. Additional pathogens that can afflict the elm are parasites that attach themselves strictly to the leaves, causing them to dry out and fall. In conclusion, wood fungi (which usually attack the wood of the trunk) are the cause for which pathologies of the bark of the elm can arise.
