Herbaceous peonies

Herbaceous and Intersectional peonies are large herbaceous perennials with attractive foliage and large bowl-shaped flowers. Choose a peony based on flower colour and shape. Colours range from white through pink to dark red and yellow. Intersectional peonies also include plants with more unusual apricot and purple shades.

Try to plant peonies in full sun and a fertile soil, which has been improved by digging in garden compost or well-rotted manure. They will grow well in a range of soils, including clay, as long as it does not get waterlogged in winter and dry out in summer. They are fully hardy so don’t need any winter protection.

We have put together a guide to help you identify your soil type. Peonies are large plants and need about a square metre (yard) of space without competition from other garden plants in order to thrive. These peonies are easy to plant and it takes just a few minutes. They are planted in the same way as other herbaceous perennials, but it’s important not too plant too deeply as this may decrease flowering.

Tree peonies

Tree peonies have attractive foliage and large bowl-shaped flowers. Gardeners usually choose a tree peony based on flower colour and shape. Colours range from white through pink to dark red and purple; yellows are available too, along with the more unusual apricot shades. The bowl-shaped flowers can be very simple with a single arrangement of petals through to fully-double, blousy blooms.

Tree peonies are best planted in autumn, but winter or early spring planting is also suitable. Avoid planting in late spring and in summer as plants will not establish well in hot, dry conditions.

Water regularly in dry spells during the first year to aid establishment, especially if planted in spring or later in the season. Established tree peonies are deep-rooted and after the first year should not need routine watering.

To promote good growth and flowering, apply a general-purpose fertiliser, such as Growmore, in each spring at 70gm per sq m (2oz per sq yd). Then mulch with a 10cm (4in) layer of garden compost or well-rotted manure to conserve moisture and suppress weeds, but avoid piling up mulch against stems as they may rot.

How to succeed with roses

Roses can be expensive plants, but they last for many, many years and are easy to establish if you follow a few simple steps on planting and aftercare. Depending on the time of year you purchase your roses, you will have a choice of types of roses:

Bare-root roses: These are only available from about November to March usually mail order. These are plants dug from open ground and packed to prevent the roots drying out before sale. Bare-root plants are usually good quality, having a wider root spread than containerised plants, and they are often good value. They should be planted as soon as received, or if ground conditions are unsuitable, unpacked and kept in a container of slightly moist compost and planted as soon as conditions allow.

Containerised roses: These are at their best in garden centres from about November to March. They may be available to buy like this for longer into the spring and summer, but quality starts to suffer the longer they are kept on display. Roses are bare-root roses placed in pots of potting media to prevent them drying out. They should be planted as soon as received.

Container-grown roses: These are available all year round. These are roses that have been grown in containers for a whole growing season or more. They can be planted at any time, (but are usually not such good plants as bare root ones) and are comparatively costly.
