A Detailed Guide to Peony Cultivation: Planting Methods and Care Essentials
For peonies, it is best to choose a relatively loose, fertile sandy soil for planting. When planting in the ground, choose a higher spot facing east with sun exposure; for container planting, place it on a sunlit east-facing balcony. If placed on a south balcony or rooftop terrace, shade it on the west side. Watering should lean toward dry rather than wet, and fertilizer should be applied at least three times a year.
1. Soil
Peonies need relatively loose, fertile sandy soil, and planting in heavy clay soil or a low-temperature location should be avoided. Before planting peonies, some diseased roots need to be pruned away to help the peony absorb nutrients.
2. Light
When planting peonies in the ground, choose a higher spot facing east with sun exposure; for container planting, place it on a sunlit east-facing balcony. If placed on a south balcony or rooftop terrace, shade it on the west side. The hot, humid weather of the south is extremely unfavorable for peony growth, so cultivating peonies in the south requires providing them with specific environmental conditions.
3. Water
If there is drought and the ground is dry, a moderate amount of water can be given, but it is better to keep things dry rather than wet, and water only after the soil has dried. Peony roots grow vertically into the soil, so loosening the soil should be done deeply. Deeply loosen the surface soil at least 3 times a year: once after flowering in spring, once after the plum rain season in summer, and once after typhoon rainstorms in autumn.
4. Fertilizing
Apply fertilizer at least three times a year. The first time is before flowering to promote blooming; the second time is half a month after flowering to replenish the nutrients consumed by blooming; the third time is before overwintering as a winter fertilizer. The main fertilizer is decomposed cake fertilizer. The amount of fertilizer should preferably be 0.5-1 kg per plant each time, and a chemical compound fertilizer can also be mixed in.
5. Pruning
After budding in spring, keep about 5 branches and remove the rest to concentrate nutrients, so that the flowers will be large and brightly colored the following year. In autumn and winter, along with clearing the garden, cut off dried flower stalks, thin weak branches, and branches without flowers. For container plants, prune and shape them as desired into the form you like.
6. Pest Control
A common disease of peonies is brown spot disease. At first, yellow-green spots appear on the leaf surface, then gradually expand to form brown or black patches. Bordeaux mixture can be sprayed 1-2 times a month, or 3 times if the condition is severe. Leaves that are more seriously infected should be cut off and burned to prevent the disease from spreading.
