In this newsletter you will find all information that is currently relevant to the crop of peonies. We trust that this information will help you in achieving a successful crop. Feel free to contact us for questions and remarks!

Dear peony grower,

For a long time now you are receiving this newsletter from us. With information regarding the cultivation of peonies. Because we are always looking for ways to improve ourselves, we would like to hear from you how relevant this information actually is. What are things you would like to see differently and are there topics on which you would like to receive more information? We greatly appreciate any feedback, so please let us know!


Paeonia is a sensitive crop. The crop is not strong due to the fast growth after sprouting. The plant repels its weakest flowers when the growth is fast while the weather is bleak. Especially during cold nights the frost will be blamed for this, but a lack of water is most likely the main reason.  A sudden spell of warm weather during the stretching increases the risk too. Do not wait with watering until the soil is dry, but make it as pleasant for the plant as possible.

Botrytis control

Because of its fast growth, the peony is hardly resistant to climate change. One of the resulting damages is almost certainly Botrytis. The fungus will especially keep causing problems when the peony doesn’t get protection during growth. In that critical period extra sprayings of the peonies are absolutely necessary. Good and effective resources in that case are Teldor, Kenbyo, Luna and Switch.

A quite new infestation in peonies is known as Phytophthora. An infection which takes place through injuries under humid circumstances. The fungus can survive in plant tissue and in the soil for years.

The first infestation can be recognized through black and weak leaves in the crop. When there is an infection by Phytophthora in the spring, brown to gray black spots will arise on the stem parts. In that case the branches will come up like some sort of black brackets and they will not grow further than ten centimeters. After infection it is almost impossible to remove.

Leaf spot diseases

Leaf spot diseases causes more and more problems in the crop of peonies. Leaf spot fungi and Botrytis create different kinds of leaf spots on the peony. Both fungi flourish under warm and humid circumstances and they survive on crop residues.

Color of the crop

A peony can get a lighter color during spring because the soil is still cold around that time and the root is not active enough. While the temperature rises and the crop grows fast. Or because of a deficiency. This may be caused by a shortage of spore elements. Especially iron and manganese can play an important role in that situation. Iron deficiency manifests itself in yellowing between the veins of the younger leaf. A manganese deficiency mainly occurs in older leaves. And iron is harder to absorb at an higher pH value (this also applies to manganese), with wet and dry ground and cold or inactive soil. This shortage can be addressed in two ways: spread more spores or perform leaf fertilization.

Peonies grow from nothing to a full grown plant in a very short time. Which cost a lot of energy. The plant needs a range of main and spore elements to make this possible. These elements are not always as readily available through the soil. Because of the low soil temperature and/or high pH value of the soil. Therefore it absolutely makes sense to provide the crop with these elements through leaf nutrition.
