Caring for your Tree Peony

Posted on by

Tree peonies.

The loveliness that’s inspired many beautiful art pieces through the ages.

And you can have one of these charming muses living in your very own garden.

They are sure to make a real statement in a sunny garden border, growing up to 2-3 metres, although they respond very well to pruning and can be kept at a more manageable 1-1.5m.

Tree peonies are long-lived, deciduous shrubs with large, sometimes dinner plate size, flamboyant, often fragrant flowers in a variety of colours. They range from white through pink to dark red and purple; yellows are also available, along with the more unusual apricot shades.

They are happiest in a sunny or lightly shaded, location sheltered from strong wind to prevent foliage and flower damage and although they can take up to four years to get settled and start flowering the rewards outweigh the wait!

You can plant containerised tree peonies at any time in the year - just remember to water it well when you plant it.

Planting Pointers

Some planting tips:

  • Tree peonies are often grafted onto herbaceous peony rootstock so the graft union will need to be planted about 15cm below soil level. This encourages it to form its own roots
  • Once in, water generously to settle the soil

 

TLC for the Tree

Technically, tree peonies aren’t trees but rather sub-shrubs so they need much the same care as herbaceous varieties.

This is how you can help your tree peony stand the test of time:

  • It is best to water regularly during the first summer especially during dry spells
  • Mulching well in late Autumn to late winter with organic matter helps keep moisture in but leave a dish around the base of the plant which is clear of any mulch as that can lead to root rot
  • Prune in the Autumn and either take back the top growth by about 1/3 in stages or, if you have a multi-stemmed tree peony, cut back every 3rd stem to about 2cm, removing the oldest stems first
  • After hibernating happily through the winter chill you’ll want to give it a little boost with a feed come Spring time

Growth Cycle of the Peony

Posted on by

Excited to introduce a peony to your garden this year for the first time or perhaps adding another one to your growing collection?

What can you expect when you order a peony from us?

All of our peonies are nurtured until they are at least 5 years old. This means they are well established Paeonia plants at flowering maturity when they go to their new homes. This means that your Primrose Hall Peony should flower from its very first season in your garden.

We grow all our peony plants in 100% peat free compost which is what your potted peonies will be in when they rock up at your door.

EARLY SEASON GROWTH

If you have already ordered a peony from us or are thinking about ordering one, the images to the right is what you can expect it to look like now in its early season growth, according to the 3 main types.

You can spot the early foliage easily with its bright reddish colour and this will change to green as it develops into leaves.

PLANTING

When planting your peonies out into your garden, the depth of planting is very important. If they are planted too deeply the roots will grow and produce foliage but flower production won't be as prolific or at all.

Ideally, for intersectional peonies, the buds, or growing points, should be 2-5cm below soil level – for tree or woody peonies, these should be plant about with the graft union about 15cm below the surface. Space them 60-90cm apart so they have room to spread out as they mature.

Make sure the soil is well-drained and has plenty of organic matter.

Water immediately after planting, being quite generous with the water to help settle the roots in.

WHEN WILL I SEE FLOWERS?

Typically, tree peonies are the first to bloom followed by herbaceous and intersectional. Intersectional or Itoh peonies often flower twice as long as tree peonies.

The following is a general guideline of the flowering season for peonies in the UK.

Weather conditions and your specific location will affect the timing - cooler areas will be a week or 2 later and warmer areas a week or 2 earlier. The length of time the flowers are produced is dependent on the variety chosen.

Very Early - flowering begins late April

Early - flowering begins early May

Mid - flowering begins mid-late May

Late - flowering begins early June

You can expect your Primrose Hall Peony to last for decades in the garden, producing more and more blooms each year. Primrose Hall Peonies can flower from April until July so make sure to look at the flowering times of each variety to ensure you have a continuous flower in the garden!

BUT WHICH ONE TO PICK?

Here are some examples of varieties to pick to enjoy flowers throughout the season:
