Peonies (Paeonia spp.) Don't send an e-mail since it could go to our spam folder and we might miss it. Water the soil deeply and thoroughly. Peonies are long-living perennials that bloom in a wide range of flower colors, including shades of pink, white, yellow and red. Death during hot summers is more likely than death over winter unless the soil is not watered properly in the fall and winter. Fertilize the peonies once each year in spring when the shoots are 3 or 4 inches tall with a granular 5-10-5 NPK formula fertilizer. Don't plant the peony tubers in hard clay soil or in a spot that's shady. Don’t plant the peony tubers in hard clay soil or in a spot that’s shady. Never just put a scoop in the hole - it can kill the plant! If you have clay soils the addition of 1 part peat moss to every 3 parts of clay soil will improve aeration of the soil and increase the height of the soil slightly making a mound and providing better drainage. We ship a standard 3-5 eye peony root for all our garden peony varieties. The plants are more cold tolerant than they are soggy wet conditions tolerant. The mulch should be removed on April 1st or after the snow has melted the following spring or as soon as ground thawing is noted as peonies begin growth very early in the spring. Hello, It seems they should have sprouted by now--have you dug them up to see if they are still viable? Set the root in the hole so that the dormant buds(eyes)will be one inch below the ground when the soil is gently but firmly filled in around the root. Without eyes, there is no peony except for an exception or two involving adventitious buds which are rare. Did you plant them properly? For this zone we also recommend that you place the peony where it is in a bright filtered sunshine during the hottest part of the day. Soak the root for 20 - 30 minutes in water prior to planting to rehydrate the root which loses some moisture during shipping. Peonies fail for some of the following reasons: We can not be held responsible for losses due to improper soil preparation, incorrect planting location, fertilizing, improperly adjusted sprinkler systems, extreme temperatures in handling or storage, extremes of weather or a delay in planting once received. If your peony is planted too deeply, you will need to replant it, though this will probably delay blooming for a few years. Dig a hole large enough to accommodate the roots without bending them. Peony roots are all different and some plants may naturally have finer (smaller) roots than others as well as some that are more inclined to be larger than average.
