Do not transplant unnecessarily.
Tree peonies do not tolerate transplanting well, especially in cool and humid climates. It is better to choose a permanent sunny location with good drainage right away.
In spring, gently loosen the soil.
After the snow melts, the soil in the Baltic States often becomes compacted. Careful loosening helps air penetrate the roots, prevents moisture stagnation and the development of fungi.
Remove faded buds.
After flowering, cut off wilted flowers — this prolongs the decorative effect of the bush and prevents the plant from weakening.
Mulch the base of the bush.
Use compost or bark — this helps retain moisture in summer and protects the roots from freezing in winter.
Cover young plants.
In the first 2−3 years after planting, it is recommended to insulate tree peonies for the winter with spruce branches or breathable agrotextile. Mature bushes can overwinter without shelter, but in winters with little snow, it is advisable to protect the base from freezing.
Inspect the bush regularly.
In the changeable Baltic climate, it is important to watch for mold or rot. At the first signs, remove the affected parts and treat with a fungicide.
