Finish planting bare-root roses.

Prune established roses. Feed with a rose fertilizer.


Late June-July:

Apply second feed of rose fertilizer.

June-August: ‘Sunblest’ is in flower. Prolong season by regular deadheading.

Spray against black spot if necessary.

Check for aphids.

Pull off any suckers (shoots from the rootstock).



Flowering continues until first frosts.


Plant bare-root roses to let them become established before the onset of winter.


December-February: ‘Sunblest’ is frost hardy, but in districts with very severe weather conditions give extra protection.

Earth up (heap soil around the plant) or place a layer of straw or conifer branches around the bush. 1, PRUNING, 1

Prune ‘Sunblest’ in spring

Remove dead, thin or, twiggy growth, cutting, back the stronger shoots to about one-third of their length each year. Prune with a sloping cut above an outward-facing bud


As well as being a good performer in the garden, ‘Sunblest’ is excellent for cutting. Its blooms are the classic Hybrid Tea shape, with elegant high-centred buds. Dry the flowers or preserve them in a mixture of water and glycerine.

BUYING ‘Sunblest’ can be bought either with bare roots from a specialist nursery in the winter months or in a container from a garden centre at any time of the year.

The rose ‘Sunblest’ is fast growing and tall with an upright, bushy habit. It reaches a height of 90cm and a spread of 60cm. Its foliage is mid-green and glossy. ‘Sunblest’ holds its colour well, giving its best tints after the flowers have been out for a while. The blooms withstand moderate rain.


Plant immediately, as long as the ground is not frozen or waterlogged. If the compost of container-grown roses is dry, water well. Plunge bare-root roses into a bucket of water for about half an hour before planting out.

Roses prefer a neutral or slightly acid soil (pH 6.5-7). Prepare the ground before planting by removing all the perennial weeds and digging well, incorporating organic matter such as garden compost or well-rotted farmyard manure.



A blue and yellow border can be stunning. The clear yellow flowers of ‘Sunblest’ look particularly attractive if blue-flowered shrubs and perennials are planted with it to complement the colour. Try lavender, catmint or Geranium ‘Johnson’s Blue’.

Do not plant roses in soil which has previously grown roses or they may succumb to ‘rose replant disease’. Either choose a new site or replace the earth to a depth of 60cm with fresh soil from a rose-free part of the garden.

Dig a hole that is large enough to accommodate the roots (about one spade’s depth should be enough).

Using a garden fork, break up the soil at the bottom of the hole.

Add plenty of rotted garden compost, and a handful of bone meal.

As you plant the bush, make sure that the bud union (bulge where the rose variety has been joined on to the rootstock) is at least 2.5cm below the level of the soil’s surface.

Firmly tread the rose in. If necessary, retread a few weeks later if you have planted the rose in winter.

Prune the newly planted rose to 10-15cm to encourage strong new growth from the base.


To control annual weeds and prevent loss of moisture, spread a 5-7.5cm deep mulch (ground covering) of sterile material, such as bark chippings, over the roots in spring.

Alternatively, under-plant with perennials, which will help control weeds and give a longer season of interest. ‘Sunblest


An open, sunny spot, in a massed planting or in a mixed border.


Like other roses, ‘Sunblest’ prefers fertile, well-drained neutral or slightly acid soil (pH 6.5).


Prune, mulch (cover ground) and feed in spring. Feed again in midsummer. Water in very dry weather. Deadhead, removing faded flowers and cutting back to a healthy bud.


On the whole, ‘Sunblest’ is a trouble-free rose. Although it has good resistance to most diseases, it may need some protection from black spot.

Spray with a systemic fungicide at regular intervals.

Remove and destroy any affected leaves. Treat greenfly attacks by spraying with a jet of water, commercial soap solution or an insecticide such as pirimicarb. ‘Sunblest’ also has excellent resistance to low temperatures, so it should not need protection in winter.
