What are the autumn care methods for peonies planted in the ground?

For autumn care of ground-planted peonies, you can divide the plants, which helps prevent the plants from aging. Shaping and pruning are also needed; after the leaves wither, leave only 3-5 vigorous branches and cut off all the rest. At this time, you also need to water and fertilize them properly.

How to care for ground-planted peonies in autumn

1. Divide the plants

For autumn care of ground-planted peonies, you can divide the plants, because if they are not divided for a long time, the peonies cannot grow new roots, and so they will gradually age and stop blooming. We can divide vigorous peonies into several suitably sized plants and then plant them separately in the soil.

2. Shaping and pruning

For autumn care of ground-planted peonies, you also need to shape and prune them properly. Once you observe that all the leaves of the peony plant have withered, use sterilized pruning shears to cut off its dense branches, crossing branches and thin, weak branches, leaving only 3-5 vigorous branches, so that it will be more vigorous and beautiful next year.

3. Watering method

For autumn care of ground-planted peonies, you also need to water them properly. At this time the temperature gradually drops, water evaporates relatively slowly, and the peony is a plant that does not tolerate waterlogging, so watering must be done according to the dryness and moisture of the soil. Keeping the soil slightly dry is best, otherwise too much watering can easily cause root rot.

4. Reasonable fertilizing

For autumn care of ground-planted peonies, you also need to fertilize them reasonably. From the Start of Autumn to before the cold winter, it is best to give the plants a topdressing of dilute phosphorus and potassium fertilizer once every 20 days. About 10 days before the Start of Winter, some slow-release fertilizer needs to be buried in the soil around the plants as a base fertilizer, so that next year they will have enough nutrients to grow.
