Common Problems of the Peony Plant
The peony plant is a solitary genus in the flowering plant family. They are generally found and grow predominantly in Asia, western North America and southern Europe. Nearly all peonies are herbaceous perennial plants growing up to 0.5 to 1.5 meters high. However, some peonies are woody shrubs that could reach around 1.5 to 3 meters high. Peonies are some of the most attractive and admired flowers due to their large and rounded, full blooms and wide variety of colors. Their leaves tend to be shiny and deeply lobed, so that they resemble beautiful lacework. Regardless of how pretty a peony plant can be though, it can suffer from some problems.
Problems are actually not more prevalent among peony plants, as these contain all the characteristics gardeners recognize most in perennials. They have aromatic flowers, endure for a very long time and are simple to grow. In addition, they are resistant to deer, drought and cold hardy. Despite these strengths, peony plants still need to be taken care of, as with most other garden plants.
Probable Causes And Risk Factors
There are several possible reasons as to why your peony plant might have some type of problem. It may be planted at the wrong depth, and may also fail to set flower buds or may still be too young. Furthermore, the peony plant may not be receiving enough sun, or it is receiving too much nitrogen. It may be suffering from a late freeze. It may be situated in a spot that is too crowded, or it may have been relocated or divided recently. Other possible causes of peony plant problems include being exposed to either excessively cold or hot temperatures, being exposed to too much water, damaged open flowers, chafers, thrips and broken or fallen stems.
Peony Plant Diseases
Peony plants can suffer from a number of diseases. They can suffer from botrytis blight, which is caused by the fungus Botrytis that affects the buds, stems and leaves. They can also suffer from phytophthora blight, which is also caused by a fungus known as Phytophthora cactorum. The buds, stems and leaves are also being attacked in this case, except that there is no felty proliferation or sporulation on the surface of the plant when in a moist surrounding. Wilt is yet another condition caused by a fungus, which is a soil-borne fungus called Verticillium albo-atrum. White mold can affect the stem and cause it to rot. Moving on, peonies can have leaf and stem spots, which are this time caused by numerous fungal organisms. The spots can differ in size and color and may be found on leaves, stems, flower petals and bud scales. The peony plant can also suffer from virus disease.
Peony Plant Care
Examine your peony plant consistently and as soon as you notice any suspicious infection or attack. The earlier you notice any changes, the better you can treat your plant effectively. Make sure you provide the appropriate drainage to avoid wilt, as this often occurs when the surroundings are moist and poorly ventilated. Slice off any infected stem and shoot right away. Make sure you completely eliminate all infected plant material, including remains like leaves and roots. Finally, you need to change the existing soil that has been infected and think about re-planting your peonies on the same spot.
