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!
Due to the heavy rain last winter, many plants have come off the root. As a result, on many plots we notice that an average of 30% less flowers are harvested. Therefore, ensure good care of the crop and good drainage!
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 Sensation and Switch. The best result is obtained when the buds are wet with dew. The fungicide then flows around it more easily. You can also use a good spreader. And spray from both sides.

The so-called ‘predator’ nematodes are predatory nematodes. These are the direct natural enemies of the harmful species. Saprophages are nematodes which do not damage the plant, but they do break down dead organic material, for example. The higher the numbers of these saprophages, the better the soil life of a plot. On top of that, it is more likely that the good and harmful soil life will balance each other.

Common swift (moth)
Root borers are ground-dwelling larvae of butterflies. These caterpillars are very harmful to various horticultural crops, because they eat at the roots of plants underground. The caterpillars hatch between May and mid-July. And in the greenhouses often before that period. They are about 6 to 7 mm long when the eggs hatch and they can grow up to a length of 4 cm. They are transparent to white in color and the gut contents can sometimes be seen as a black streak through the insect.

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. Therefor it absolutely makes sense to provide the crop with these elements through leaf nutrition.

Leaf rollers owe their name to the fact that the caterpillars string themselves between the leaves. And that causes the leaves to roll up. In the case of peonies, this little black caterpillar eats its way to the flower bud of the plant. This roller isn’t only hard to find, but the creature also causes damage directly to the flower bud. Therefore controlling regularly on leaf rollers is necessary.
Mole crickets are digging insects with highly developed forelimbs. They can get about 5 centimeters big. They live of larvae (cutworms and leatherjackets) and other soil insects. Supplemented with plant material.

When planting peonies; the benefits of investing in 3-5 eyes compared to 2-3 eyes:
Number of stems / flowers per plant (2-3 or 3-5 eyes):
|Variety||Year||Amount of stems||Amount of stems|
|2-3 eyes||3-5 eyes|
|Sarah Bernhardt||Planting in autumn: 2020|
