How to water the peony
The peony is a plant native to China and above all, able to survive even in the most rigid climates. For this reason, wetting the peony is not a complicated process. This plant does not need much water and can be watered rather occasionally. However, during the wetting process it is very important to check that the water reaches the roots in depth. On average, about 5 liters of water each week is sufficient for the peony. As for the peony grown in pot instead, the watering must be more frequent. In this case it will be possible to check the soil and irrigate the peony each time the soil is completely dry. The frequency of watering can be kept constant regardless of the seasons.
Peony, whether of shrub or herbaceous species, can only be planted in autumn or spring. When planted in autumn, it is good to use plant supports that can protect it from strong winter winds. The plant should never be pruned, its pruning could indeed be very harmful. As for the propagation of the peony, there are several procedures. The most widespread, but also the longest, is sowing. The seeds must be buried in compost for seeds inside the terrines then placed in a cold box. The plants must be re-covered once they are born, around May. However, you have to wait 4 years before the new peonies are planted. A faster way instead is to give birth to new plants from the tufts, being careful to get at least one bud.
How to fertilize the peony
For a correct fertilization of the peony you can opt for compost or for a fairly mature manure. Compost is generally the result of a bio-oxidation of organic matter. This process is carried out by different types of organisms in particular conditions such as: presence of oxygen and balance between the chemical elements involved in the transformation. If the ground is rather sandy or calcareous, it is necessary to reinforce it. In this case it is therefore necessary to use the compost or mature manure also on the ground itself. However, the soil can be fertilized exclusively from March to April. The ideal soil for the cultivation and growth of the peony is rather wet and well drained. It is also important that it has a neutral pH or at least a slightly perceptible acidity.
Peony: Diseases of the peony
Peony can be affected mainly by fungal or parasitic diseases. The most common type of parasitic disease for the plant is leaf eel. The cause of this disease is found in the nematoids of the Aphelenchoides olesistus species. Leaf eels generate leaves with a translucent and chlorotic appearance. If the disease degenerates, the leaves tend to dry out and then fall off. When the first symptoms of leaf eel are noticed, it is good to act quickly with a specific pesticide. Very often the peony can also be affected by the fungus Botrytis cinerea which causes gray mold. This fungus attacks the new shoots by making them rot and turning them brown and then covering them with a gray mold. Also here, as soon as the first symptoms are noticed it is good to act quickly with some fungicide.
