Question: what affects my peach tree?
I bought a peach nano this winter, it bloomed very well in the spring, it started to bear fruit and developed a lot.
Lately, however, I have noticed that on the trunk and on the branches there are yellow spots followed sometimes by larger dark spots. I tried to touch one of these larger spots and broke, there is white powder inside.
Of all the fruits that had only 2 they turned into peaches (still on the plant and well developed).
Apparently the plant looks healthy, the leaves are beautiful and green, but the fruits have all fallen after they dried ...
Do I have to worry? Is it perhaps a type of plant fungus or maybe an excessive amount of fertilizer (I used a long-release granulated horn)?
Thanks for the help, greetings
Answer: peach diseases
your peach tree is very young, for this reason it is normal that it has not managed to complete all the fruits, it often happens that a young fruit tree produces a lot of flowers, which are all pollinated; but later, the need for the foliage and foliage (due to the fact that the plant is young) leads the sapling not to have sufficient "energies" to complete all the fruits, which then fall. Often it happens that in the early years everyone also falls. Clear that, a good fertilization and regular watering in the spring period, above all between the flowering and the production of the fruits, can favor the setting of a greater number of peaches. Avoid excesses, however, and water only when the soil is dry, or when the climate is particularly dry. As for the spots instead, a lot depends on the dimensions they have, if they are small specks, like pinholes for instance, it could be cochineals, or other insects; if, on the other hand, the spots are larger, they could be fungi or molds. In the first case, do an autumn and a late winter treatment with white oil; in the second case, it regularly practices (about every month) copper-based treatments.
One of the most common pathologies that can affect plants of this type is the so-called peach bubble; this is a disease caused by a fungus that tends to appear when the climatic conditions present a high degree of humidity and there are high temperature ranges between day and night. Usually, this problem affects mainly the leaves and the shoots, but in some cases it can spread to the whole plant. The leaves no longer allow the process of photosynthesis to take place, so that the whole specimen appears sick and wasted. In the hottest season the problem tends to stop but it is essential to act preventively with regular treatments with copper-based products, especially when there is germination. The first signs of this type of problem appear in the spring period. It is essential to provide regular interventions with the use of copper-based products as the disease does not have an effective remedy when it occurs.
Peach problem: peach pests
In addition to the bubble, there are numerous other problems that can affect this type of plant. Among the most common we find aphids, which are deposited on the leaves and must be contrasted with special insecticide products. Other common pests are scale insects, which must be eliminated quickly because they feed on the plant's sap. A serious problem is represented by the attacks of the fruit fly, which attacks the fruits and causes their rotting.
