Peonies in Autumn

Although we may feel like taking a bit of a break after a strange summer and all the Chelsea excitement, work does not stop when Autumn comes around.

Don't put those tools away just yet, there are plenty of things to be done in the garden! And not just playing the fool (although that is important too)!

Here are some suggestions of best garden practice in Autumn.

Planting

September and October are the ideal time for getting those new peonies in the ground. In short, you'll want to:

  • plant them in a sunny/partly shady and sheltered spot
  • make sure the soil is free draining
  • plant herbaceous peonies with the crown no more than 5cm below the ground. With container grown plants, simply plant them out at the same level as they were in the pot

Moving and Dividing

If you have a well-established peony in your garden that’s happily expanding, late October/early November is the perfect time to move and/or divide it. Contrary to popular opinion, peonies don’t mind a change of scenery. In fact they quite like it, as long as you follow a few simple guidelines:

  • Cut back any dead foliage to about 2cm above the ground
  • Dig up as big a clump as possible, being careful not to damage any ‘eyes’ or buds that are developing at or just below surface level
  • Divide your peony with either a sharp spade or a pruning knife (depending on the size of the plant), ensuring that each piece of root that you divide has at least 3-5 ‘eyes’ or buds
  • Whether you are moving or dividing your peony it is best to plant it as soon as possible after lifting it to minimise disruption to the root system - ideally planting it the same day

 

Like us, peonies take some time to adjust to new things, so it may happen that your peony will not flower the following year. As long as you have taken the above care in replanting it, you don’t have to worry. This is normal and it is just taking some time to settle in to its new position. It will no doubt flower in years to come.

In the meantime

Before you start launching into getting your peonies ready for their next fabulous flowering season, there is something worth taking a few moments to savour – their foliage.

The colours on peonies Autumn leaves is a feast for the eyes. You can expect to see varying shades of reds, oranges, purples, greens and browns.

It’s really such a treat and a great opportunity to take some time out from the day - best enjoyed with a fellow nature enthusiast, relaxing on the garden bench over a cup of tea.

The range of autumn colours on Herbaceous peony leaves is very wide but Intersectional peonies foliage maintain their rich hues and last considerably longer than Herbaceous peonies in autumn. And while Herbaceous leaves tend to go brown and shrivel up before dropping off, Intersectionals leaves maintain their form and prettiness right until the very end. Look at them showing off their fancy foliage (pictured right)!

And that’s one of the many reasons we love peonies – their ability to remain elegant, no matter what!

Peony Myths Debunked – Part 1

With all the fake news we find online these days it’s no wonder that peonies also have some “interesting” ideas floating around about them.

In this two-part series we’ll be debunking some of these myths.

Peonies Are Difficult to Grow

Peonies are actually quite easy to grow if a few simple rules are followed:

  • buy a well-established, mature plant
  • plant in a sunny/part-shaded and sheltered position
  • make sure whatever type of soil it is that it is free-draining
  • plant herbaceous and intersectionals with the crown no more 2.5cm below the surface
  • water consistently while buds are forming in spring
  • don’t over-water as peonies don’t like to have soggy ‘feet’ or roots
  • mulch, but not too much
  • feed once a year in the spring/autumn/summer
  • cut back herbaceous and intersectional peonies in autumn
  • prune tree peonies

 

Peonies Don't Like Cold Weather

Will your peony endure a snowy winter? Even though they may look delicate, they are hardy down to -25C and have been growing for many generations in parts of China, Japan, North America, Europe and Alaska where it is very cold.

Peonies need the colder weather to hibernate and get to work on new buds for Spring time. In fact, many growers have said that the colder the winter the better the blooms will be the following season.

The only time your peony may take a bit of strain is if there is a late frost, as it can damage the leaves. However, your peony won’t be beyond repair and will likely be back to its old self by the next season.

Peonies Only Grow in Certain Types of Soil

Peonies will be happy in any type of soil. The only necessity, no matter what soil you have, is that it is free draining.

Even if it is clay! Yes, clay!

That said, it can be a bit tricky to ensure clay soil drains well. If it is very hard-packed clay you’ll want to mix in some sand or stones before planting.

Specialist peony fertiliser will be a welcome addition to the soil when planting a peony in your garden for the first time. This will enrich the root growth in the first season.

Peonies Hate Moving

Who likes change? Ok, ok, some of us do. But most human, animal and plant beings are creatures of habit (or habitat) and will protest at being uprooted from their homes.

However, contrary to popular opinion peonies really don’t mind being moved. They just need to be handled correctly.

Here are some tips:

  • autumn after cutting back/pruning is the best time to move
  • ensure eyes (pink buds) on the roots are not damaged in the process
  • don’t over-mulch/cover them with too much soil
  • herbaceous and intersectional – crown (top of the plant) no more than about 2.5-5cm below surface
  • grafted tree peonies – graft union no more than about 10-15cm below surface

 

Peonies Don't Last Long

Absolutely untrue! In fact, you may need to leave them in your will as some have been known to live on happily for more than 90 years!

Because peonies take a while to mature, flowering from around 3-5 years old, some may have dug up their peonies prematurely thinking they’re dead.

This is why it’s best to buy your peony at flowering maturity from a reputable nursery so you can enjoy flowers every year from year one.

 

And that’s all for now! We hope this has helped you come around to the idea of adopting a peony.
