The best time of year for transplanting peonies is September. Clip leafy stems back to near ground level—2 to 3 inches tall. Use a sharp spade to dig beneath the peony clump. Gently shake the peony plant so soil falls away from roots. September is the best time to transplant established peonies. Begin by cutting the peony stems near ground level. Then carefully dig around and under each plant. Try to retain as much of the root system as possible. Dig the plants carefully to minimize root injury, and remove the foliage. If the plants are large, they'll probably do better if they're divided. Gently wash the soil off the large roots, then use a sharp, clean knife to divide the plant's crown. Make sure each division has 3-5 pink buds or healthy stems. If you want to transplant a peony, ideally you should wait until fall when the plant dies back. However, if you move your peony in the spring just as new growth occurs, it should fare well, though it may not bloom as well the first year. Water the peony with 1 inch of water one or two days before transplanting. The best time for propagating peonies is in autumn, after plants have become dormant. The procedure for dividing peonies is very simple. To lift and split entire clumps of peonies, start by digging around the plant very carefully. When you can lift the peony clump out of its planting spot, shift it gently onto a tarp.
Instead, place coffee grounds around the edges of where the leaves are. If you use it as a preplant fertilizer, if it's very diluted, won't matter, but may want to place 1-2 months before you put seeds in if you are using this as your primary source to get the benefits and not many of the downsides.
Cut the foliage to the ground in the fall to avoid any overwintering diseases. Don't smother peonies with mulch. Where cold temperatures are severe, for the first winter after planting you can mulch VERY loosely with pine needles or shredded bark. Remove mulch in the spring.
Set them in place in early spring so stems can grow through the grid. Peonies rarely bloom the first year after planting. Use a sharp knife to cut apart some of the plant, making sure to create generous clumps of roots with at least three to five eyes per clump.
The only way to multiply peony plants is to divide peonies. These will actually be the part that comes through the ground after planting and forms a new peony plant when you divide peonies. After rinsing, you should leave the roots in the shade so they soften up a bit. They will be easier to cut.
The best time of year for transplanting peonies is September. Clip leafy stems back to near ground level—2 to 3 inches tall. Use a sharp spade to dig beneath the peony clump. Start digging about a foot away from the stems.
Tree peonies prefer dappled shade and good drainage Unlike herbaceous peonies, which bloom best in full sun, tree peonies prefer partial shade, with three to four hours of sunlight. The plants grow faster in sun, but the flowers burn and vanish in a day or two.
You can successfully grow and flower peonies in pots. Choose a pot at least 30cms (12 ins) in diameter with adequate drainage holes at the base. Use a soil based compost such as John Innes No3. Peonies do not thrive in peat-based composts.
Choose peonies that will grow well in your garden conditions. Plant peonies in full sun in the fall or spring. Prepare the soil by adding Miracle-Gro® Garden Soil for Flowers. Add Miracle-Gro® for Fresh Cut Flowers to water.
Peonies divided in the spring grow very poorly. So, four to six weeks before hard frost, when the leaves begin to look ragged, cut back the foliage and dig up the plants. On the fleshy crown you will see protruding dormant buds (“eyes”) that will be next spring's red shoots.
To get your peonies to bloom, make sure they're planted in an appropriate area and take care not to over-fertilize them. You can also cut and store peony buds and get them to bloom in a vase long after the blooming season is over!
Peonies need sun to produce blooms. It could be that the plant got enough sun in early spring to generate the buds but a nearby tree grew back its leaves and the sun is now blocked. The buds die because the plants no longer get enough sun to support the blossoms.
The ideal times are in spring or early autumn. In most regions, if you can time it right, plant to transplant hostas before seasonal rains arrive. Early fall is probably the absolute best time to tackle transplanting hostas, because soil is still warm from long summer days, which means hosta roots will grow quickly.
Plants that are growing poorly (weak, spindly, yellowish or "off-color") are not vigorous enough to bloom (but may set buds). The most common reasons peonies fail to bloom are cultural (planting in too much shade and planting too deeply).
Step 1: Prep for Success. Stick mainly to fall and spring for transplanting. Step 2: Prepare the Plant's New Home First. Digging a Hole. Step 3: Soak the Soil. If the soil is very dry, water the plant first before digging it up. Step 4: Dig It Up. Step 5: Place in Hole and Add Organic Mulch. Step 6: Water Slowly and Deeply.
