Planting, Growing, And Caring For Peony Flowers

Peonies are generally very hardy. Plus, peonies are also one of many deer-resistant plants you can grow in your garden.

However, they are susceptible to:

  • Verticillium wilt
  • Ringspot virus
  • Tip blight
  • Stem rot
  • Botrytis blight
  • Leaf blotch
  • Japanese beetles
  • Nematodes
  • Aphids

FAQ

Why are there ants on my peonies?

Many gardeners wonder why so many ants crawl on the peony buds. Don’t worry! They are just eating the peony’s nectar in exchange for attacking bud-eating pests. They are attracted to the sugary droplets on the outside of flower buds or to the honeydew produced by scale insects and aphids. Never spray the ants; they’re helping you by keeping your peonies safe!

Why are my peonies not blooming?

There are a few reasons why your peonies fail to bloom. If it is planted too deep (the eyes should only be about 2 inches below the soil), it will lead to beautiful foliage but very few flower buds. Depending on your fertilizing schedule, it may be receiving too much or too little fertilizer. Also, remember not to remove the foliage too early in the season. Wait for the foliage to die back naturally before removing it after the first frost.

Peonies need a certain amount of cold weather in the winter to set buds and to flower. If you live in a warmer location, your peonies may be getting just enough cold weather to produce the buds, but not enough to make them flower.

Bud blast can also be the cause since it results in buds turning brown and shriveling up. The best thing to do is to make sure it has the ideal growing environment in terms of sun, fertilizer, cold winter temps, and proper planting depth.

Can I plant the seed pods on my peonies?

The pods that remain on your peonies will contain seeds. You can collect the seeds when the pods turn dark brown and slightly crack open. To make sure that you don’t lose seeds to birds or weather, tie nylon or small mesh bags around maturing seed pods before they split open to catch any seeds that may fall. Ripe seeds can be planted immediately after collection.

Peony seeds require a warm/cold cycle to produce their first true leaves in the spring. In nature, seeds are dispersed on warm late summer to autumn days and quickly germinate. By winter, they form small roots. They are then dormant during the winter before emerging in the spring. Press peony seeds into the ground at no more than a 1/2 inch depth. Then cover with an inch of wood chips to provide protection.

You can certainly dry and save seeds for future planting, but dry seed takes longer to hydrate than fresh seed, and dormancy is more difficult to break.

Can I grow peonies indoors?

Yes, you can, although they are best grown outdoors. Inside, you’ll need to provide enough light (about 6 to 8 hours); if you don’t have enough natural daylight, a grow light can help. It is also necessary to give them a period of cold (about 3 to 6 weeks, depending on variety, of temperatures between 32 and 40 degrees F) over winter, which is needed for flowering. If you live in a cold climate, this can sometimes be done by leaving the pot in a cool garage or shed, with the top of the soil covered with straw to protect the roots once plants are dormant; remove the straw at the first sign of growth in spring.

Select a variety of peony that is shorter (not those that can grow to 4 to 6 feet, for example); if you live in a warm climate, choose a variety that does not need as long a period of cold (aka “chilling hours”) over winter. Plant in fall or spring. Choose a heavy pot (ideally, not terracotta) that is about 18 to 24 inches wide and deep, with drainage holes, and fill with rich, well-draining potting soil. Keep soil evenly moist but not soggy; when plants are established, you can let the soil dry out a tiny bit before watering deeply.

How long will it take my peonies to bloom?

Peonies typically take 2 to 3 years to bloom after planting, especially if planted from bare roots. The first year is focused on establishing strong roots, and blooms are usually sparse or absent. By the second or third year, you’ll see more consistent and fuller flowering.
