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!

Weed control

Weed control in peonies does not go without problems. Especially now – the period before the growth of the eyes – it is best to spray Kerb in combination with Chloor IPC or Stomp and add a binder to it.

Top quality peonies require good fertilizers. The time in which some of this or that was enough, is over. Peonies that have been growing for a couple of years can exhaust the soil and surely need fertilizers.

It is all about balance. As with most things in life, this is also the case for the soil.

Main elements

The element nitrogen is most easily absorbed by the plant. Lots of nitrogen is needed during strong growth, like in the first weeks at the vegetative stage (length growth). There are two forms of nitrogen in your soil: ammonium nitrogen and nitrate nitrogen. Equal amounts of these two forms is ideally (a 1:1 ratio).

A lack of nitrogen causes the plant to get light green or yellow foliage, flowering too early, less length growth and vulnerability to fungus diseases and insects.

An excess inhibits Ca/Mg and boron uptake.

The first shoots are coming out of the ground. The plant wants to get its sugar transport going again. Especially in this initial phase the crop needs boron, silicon and calcium. These three elements play a crucial role in the start of the growth.

1) Boron activates silicon

2) Silicon starts the absorption of elements, starting with calcium

3) Calcium takes care of strong cell walls and thus a resilient crop

In the greenhouse and in the tunnel, the water supply is decisive for the result. Moisture leads cold into the ground. Moist soil and a proper organic matter content are important for the uptake of the fertilizers mentioned above. Drought during this period will damage flower production for the coming season.

Slugs: the sneaky killers in your peonies!

Slugs can cause a lot of damage in the winter months and early in the spring. Under glass, but also in your peony fields. Therefore be alert for gluttonous slugs and prevent damage to your peonies.

Slugs (without a shell) and snails (with a shell) are mollusks. Slugs without a shell mostly appear under glass and they can cause much damage in many varieties. They are not very particular in their choice of food.

The first treatment against Botrytis has to take place when the plants start to emerge. The fungus lingers during the winter at the surface of the soil. Therefore the new shoots will be infected when they emerge from the soil.
