The plants of the garden

Very often the home garden is used not only as a private and personal place to relax and devote oneself to one’s family, but also as a place to carry out a hobby; if we think that one of the most popular and loved hobbies is that of the “green thumb”, then it is very simple to conclude that in the garden you can give free expression to your love for plants and for all the activities that can be carried out with them. In particular, all those daily attentions they need help to create an emotional and psychological bond in us, since we feel that our body is fine if it carries out those activities, our mind relaxes and is distracted from daily negative thoughts. and it is therefore important that we engage in these recreational and healthy activities every day.

Plant diseases


Given that for many people plants are still more than living beings, but they are almost little people who manage to help our mood, their treatment also addresses those diseases that affect and weaken them, just like ours. diseases do with us humans. And just as happens to us, those around us immediately recognize if we are not well, from the eyes, from the color of the skin and from our attitudes; for those who take care of the plants the same thing applies, in the morning (watering time) you immediately see that something is wrong and you are activated just as if a small child had a fever. Even in the case of plants, diseases can be various, with multiple effects from the mildest to the most serious and with many causes. There are the wrong attitudes, as when we do not wear the shirt of health and take the classic cold, so also having wrong attitudes towards plants (excessive or poor exposure to air, exaggerated abundance of watering) facilitate the onset of diseases. This tendency is exacerbated when the plant is out of its habitat and / or its climate, that is when we have a tropical plant in our temperate climate or when we breed plants in an apartment.

Scab

Scab is one of the most common plant diseases; it is very recognizable from a visual point of view because it consists of some brown spots with a yellow outline (caused by the discoloration of the leaf around the spot) that appear on the surface of the leaf and which then go more and more to enlarge until they cover the whole leaf bringing it to total desiccation. This disease attacks fruit plants in particular, and in particular the scab of the apple tree, that of the pear tree, that of the Japanese medlar are known; not only that, its variants very often attack flowering plants such as the rose, which particularly suffers the effects by almost completely stripping of the leaves. The scab is caused by fungi that attack the plant, in particular from a genus of fungus which in the case of apple and pear is different from that which attacks the rose and other flowering plants. An aspect of this disease that can relieve us is that, even in the most serious cases, it does not lead to the death of the plant but only to its total stripping, even with the drying up of the younger branches.

Process and care

The progress of the scab starts, as we said earlier, from the leaves; once the disease has taken the whole leaf, it goes up the branch and attacks the youngest branches of the plant. Lastly, in fruit plants, the disease is seen to arise and progress even on the fruits themselves, precisely because they are the most extreme and important part of the plant. Scab has no real direct causes, but there are conditions that greatly help development, and there are two in particular: water stagnation with excessive humidity and little air circulation. In the first case the solution is simple, that is, avoid overwatering the plant but rather respect the dosage by checking the state of the soil; in the second case, instead, to promote air circulation, it is good practice to carry out a good pruning with disposal of the oldest and therefore less productive branches, in order to free up energy for the plant and space for the circulating air. These precautions can be accompanied by a preventive treatment based on copper compounds for plants (such as “verdigris”); this natural element and quite tolerated by man, has a good effect in removing the fungus from the plant. Finally, remember that this disease is also transmitted by air from plant to plant, and it is good to burn infected leaves, fruits and branches once they have fallen. this natural element and quite tolerated by man, has a good effect in removing the fungus from the plant.
