PLANTING YOUR LYNDAKER FARMS' PEONY
To ensure a successful peony planting we recommend the following steps:
PLANT YOUR BARE-ROOT DIVISIONS IN THE FALL.
We only divide and ship peony divisions in the Fall. Dividing and planting at other times will unnecessarily stress the plant and your plant may never fully recover or may even die.
In our northern climate, we try to have our bare-root peonies in the ground no later than the end of October.
Once you receive the plant in the fall, we recommend that you plant it as soon as possible. if you can't put it in the ground immediately put the root somewhere cool and dark. A basement or even your refrigerator will work well.
MAKE A LARGE PLANTING HOLE TO EASILY ACCOMMODATE THE ROOTS.
You do not want to "squeeze" your peony root into the hole. We typically dig an approximately 1'x1' hole for our herbaceous and itoh peonies and a 1.5x1.5' foot hole for tree peonies.
If your soil is compacted, you may consider digging even larger holes than those listed above. This will ensure the plant has space to expand, despite the somewhat challenging growing conditions.
FOR HERBACEOUS & ITOHs, PLANT CROWN NO MORE THAN 2" BELOW SOIL SURFACE.
If you plant the root deeper than 2" the peony will flower poorly or not at all.
In the south, I understand that gardeners intentionally plant their peonies less than 2" deep. This helps ensure the root gets a good chill in the winter, which the plant needs in order to flower well and profusely. If you’re growing peonies in a warmer climate and want to adjust planting depth, talk to gardeners in your area to understand the planting depths that work for them.
If you’re gardening in Zones 3 - 5, it’s wise to stay with the 2” planting depth (but no deeper than that).
If in doubt err on the side of planting Herbaceous and Itohs too shallowly
For tree peonies, Plant the Graft at least 4 inches below Soil Surface
To ensure your grafted peony develops its own root system, make sure the graft is buried at least 4” below soil surface.
This planting depth is consistent for all growing zones.
If in doubt, err on the side of planting Tree Peonies too deeply.
PLACE THE PEONY IN THE HOLE
When placing the peony root in the hole, we recommend that you first gently spread out the roots. Then put dirt into the first 6-8 inches of the hole. Place the spread out roots on top of the mound of dirt with the crown side up.
At that point, confirm that the crown is no more that 2" deeper than the soil surface (herbaceous and itohs) or for Tree Peonies, that the graft is buried at least 4” below soil surface.
You may choose to water at this stage, just to help eliminate air pockets.
To finish the planting, you then cover the root with soil until the hole is filled to the existing soil surface level. Water again to remove air pockets.
IN COLDER AREAS, CONSIDER MULCHING FOR THE FIRST WINTER ONLY.
In the colder regions, this protects the new planting from winter damage. The mulch is only needed the first winter and should be removed immediately in the spring.
