Shading tree peonies in summer can prevent leaf diseases

In recent years, air pollution has become increasingly serious, and leaf diseases of tree peonies have also worsened, with the onset of disease occurring earlier, causing premature leaf drop in tree peonies. The phenomenon of autumn sprouting is severe, affecting growth and development the following year. Although this problem has attracted great attention and various control measures have been adopted, the results have all been less than ideal. Proper shading in summer can extend the effective growth period of tree peonies, reduce leaf diseases, lessen the phenomenon of autumn sprouting, and benefit the growth of tree peonies.

Intercropping annual tall-stemmed crops with tree peonies can not only provide shade but also increase economic income. Here, the intercropping of tree peonies and sunflowers is used as an example for illustration.

In the north, sunflowers are mostly direct-sown in the open field, generally sown with seeds in early to mid-April; by early May their height is basically the same as that of tree peonies, and only in June can they provide a shading effect, which exactly avoids the vigorous growth period and the best ornamental period of tree peonies. Moreover, sunflowers have few diseases, making them one of the ideal intercrop and relay-crop plants for tree peonies.

The specific method is as follows: sunflowers are planted on raised beds and ridges, tree peonies are planted at a row spacing of 60 to 70 cm, with 3 rows per bed, and one row of sunflowers is inter-sown every two beds, with a plant spacing of 2 m. This way, effective shading is provided while maintaining good ventilation, and throughout the entire growth process there is no strong competition for water or nutrients, which is very beneficial to the growth of tree peonies.

Experiments have shown that shaded tree peonies have a low incidence of leaf disease, a low degree of damage, and a longer retention time of green leaves, which is beneficial to growth the following year.

Shading tree peonies in summer can prevent leaf diseases

The tree peony is a traditional famous flower of our country. During its growth and reproduction, it is subject to damage from many kinds of diseases and insect pests, which may cause young stems to drop, leaves to become incomplete, or various disease spots to form on branches and leaves, and may even cause withering and death, affecting the ornamental value of the flower and causing economic losses.

In recent years, air pollution has become increasingly serious, and leaf diseases of tree peonies have also worsened, with the onset of disease occurring earlier, causing premature leaf drop in tree peonies. The phenomenon of autumn sprouting is severe, affecting growth and development the following year. Although this problem has attracted great attention and various control measures have been adopted, the results have all been less than ideal. Through observation and practice, the author has demonstrated that proper shading in summer can extend the effective growth period of tree peonies, reduce leaf diseases, lessen the phenomenon of autumn sprouting, and benefit the growth of tree peonies.
