CARE OF PAEONIES
PREPARATION FOR PLANTING PEONY TUBER
Find a nice sunny, open, free draining spot and double dig or fork down deeply until it is nice and loose.
NEVER dig any compost or organic matter into the hole. If you determine your soil is deficient in nutrients, trace minerals and potash based fertilisers can be added sparingly during planting. We recommend you always use organic products for your own and the earth’s wellbeing.
When planting tubers, the buds must be max 5cm (2 inches) below the surface of the soil as they won’t flower well if planted deeply. Place the tuber in the shallow hole, cover with soil, firm down and water well. DO NOT cover with anything other than soil (ie mulch), as this will stop the tuber from getting the cold that it needs over the winter for it to flower well. To flower well, a peony needs 80 days of cold on the ground above its tuber. This cold does not have to be hard frosts, but the temperature needs to get down to single digits for a couple of months.
As long as peony plants are given water when it is really dry, they take very little care and practically look after themselves, giving joy and countless blooms for years.
Pæony grow from TUBER, (often mistakenly called roots, rhizomes or bulbs). When tubers are first planted they put out fine feeder roots and then develop storage roots. When you buy a tuber, these fine feeder roots may or may not have already started to develop.
The main disease affecting peonies is botrytis, which is spread by raindrops and humidity and can spread rapidly throughout a crop. It attacks the leaves, stems and buds making them rot and go brown. If operating conventionally, treat with a systemic contact fungicide spray. Rose spray works well if used at the same strength as recommended for roses – organic alternatives are available. It is important to remove infected parts of the plant and destroy them by burning. Botrytis is weather related, so just because you have it one year, does not mean it will happen next year or vice versa.
Leave the plants to die down naturally in Autumn/Winter, so that the roots can retain nutrients from their stems and leaves.
In late May/June, once frosted, cut each stem at most an inch above the ground. NEVER pull the stems out, as flower buds may come out as well. Peony stems and leaves don’t break down readily and can potentially carry diseases over to the next season – in order to break this cycle they should be burnt or mulched and applied well away from your peonies.
SHIFTING, DIVIDING OR PLANTING A PEONY
Whether shifting the whole plant or just taking a piece, the plan of attack is the same. You must dig the WHOLE PLANT UP! Using a spade, dig the plant up. Do not worry if some of the long woody roots get cut off. Wash it well and cut roots to 5 or 6 inches long. Tidy any jagged roots.
CARE OF PÆONY AS A CUT FLOWER
|If the blooms are cut at the right time, Paeony is a very long lasting flower with a vase life of up to 10 days. However, cutting at different stages of opening can shorten or lengthen their vase life. When cutting flowers, you are looking for petal movement at the top of the bud. Find nice fat buds with colour showing at the top and before cutting squeeze the bud from each side. If you see the petals move, then cut the stem. If the petals do not move, even though colour is showing, the flower will take much longer to come out, and in some cases doesn’t come out at all. The varieties are very different, and some are quite big and partly opened before petal movement is seen, whilst others seem to have just started to show their colour and the petals will move. Picking a bud when it is half open will only shorten its life by a day or two so that is fine. When picking a full blown Peony it is hard to know how many days it has been out, and the vase life will be affected, but as long as it is not faded or old looking then you should get about 5 – 6 days of vase life which is still good.
Try to pick the flowers early in the morning or in the evening, rather than in the heat of the day.
When picking a bunch that needs to be kept for a while or to be given away, a little extra care will be very helpful to them. As soon as they are picked put them in a bucket of water with a few added ice cubes if available. Keep them in a cool place where sun and light is limited. If travelling a long distance, put them on damp newspaper with a chilly pad at the base of the stem and roll up lightly. Then roll in more newspaper ensuring the top and bottom are folded in so the flowers are encased in a cool damp situation. Choose a large size vase as Peony are a heavy flower. Recut stems to good length for the vase. Snap off any lower leaves. NEVER let the flowers run out of water as it is hard, and often impossible, to resuscitate them. To give longer vase life, keep in a cool place and it is believed that the addition of an ice cube a day makes for lasting and happy cut Paeonies.
