Whenever you see yellowing plants in the peony fields, after excluding diseases, it is basically certain that it is caused by underground pests, grubs.

How to Plant and Care for Peonies

1. Planting time is generally in spring and autumn, with autumn being the best. But no matter when you plant, low temperature is needed to break the dormancy period.

2. Before planting, you can soak the bare-root seedlings in clean water for 30 minutes to allow the roots to fully absorb water.

3. Peony likes light but is cold-resistant. It must be planted in an environment with sufficient light so that it can grow luxuriantly and have bright colors.

4. It is suitable for planting in places with deep soil, loose and fertile soil and good drainage. If it is potted, gravel can be placed at the bottom of the pot to facilitate drainage.

5. The buds should be planted upwards and covered with 2-3 cm of soil. If the buds are longer, you can also plant them with half of the buds exposed, and there is no need to cover the soil too deeply.

6. Peony has fleshy roots and is not tolerant to waterlogging. Waterlogging can easily cause bulb rot. Generally, water twice before planting, once before winter, and water appropriately after spring depending on soil dryness or wetness.
