Chicago Peace – A great all-rounder

Vigorous and dependable, ‘Chicago Peace’ is an excellent choice for bedding or mixed border planting and can even be used to make a colourful hedge. It has large, faintly scented blossoms of a coppery-pink hue, tinged with yellow.

ANNUAL CALENDAR

SPRING

March-April:

Prune and begin regular spraying against diseases.

Spray against insect pests as necessary. Feed with rose fertilizer around the base of each plant.

SUMMER

May-July:

Deadhead (remove dead flower-heads) regularly. Apply second dose of fertilizer in July.

AUTUMN

August-September:

Plan new plantings and prepare planting sites.

WINTER

October-February:

Plant new bushes and tidy up established rose-beds, destroying fallen leaves and other debris that can harbour diseases.

Roses grown in sandy or chalky soils will benefit in particular. Turn the tap on low and let water trickle gently around the base of the plant. In heavy and clay soils roses are fairly drought resistant, but it is important to water in very dry weather.

Apply a permanent mulch of well-rotted compost or manure to help conserve moisture.

IMPORTANT

Take care not to plant new roses where roses have been grown for up to 3 years before as the soil may be ‘rose sick’. It is always best to select a new site. 1, PRUNING,

Careful pruning helps to maintain a healthy plant

Use sharp secateurs and cut, just above an outward-, facing bud, slanting down, and away from the bud

First remove all dead and, diseased stems, cutting, back to healthy wood. Then remove all thin, weak stems, cutting back to stronger growing branches.

Finally, cut out all stems growing in towards the centre of the bush or any crossing branches. The aim is to create an open-centred framework of sturdy stems

The ‘Chicago Peace’ rose is so called because it was discovered growing in a garden in Chicago, and it has as its parent the internationally renowned ‘Peace’ rose.

Developed from a sport (chance offshoot) of a ‘Peace’ rose, ‘Chicago Peace’ has the large blooms, reliability and versatility of its parent, but is bolder in colour. It makes an attractive show rose.

Planting

Autumn is the best time for planting, as this gives plants time to settle in and make new roots before starting into growth the following spring.

Plant in a hole 45-60cm deep so that the union (bulge where rootstock and stem are joined) is at least 2.5cm below the soil surface.

Break up the bottom of the planting hole and stir in some manure. Mix a handful of bone meal into the soil removed from the hole.

Cut back any long or damaged roots and fan out the roots in the bottom of the hole, sprinkling soil around them to hold the plant in position while you back-fill the hole.

When the hole is two-thirds filled, gently shake the plant up and down to work soil around the roots.

Finish filling the hole and gently tread around the plant to firm the soil. Top-dress with a mulch (ground covering) of well-rotted manure or garden compost.

Cultivating ‘Chicago Peace’ flowers from early summer to late autumn. Deadhead regularly by cutting back to the bud where the first stem will grow.

During dry spells, always water regularly.

EXCELLENT CUT FLOWERS

Due to its splendid colouring and shapely blooms, ‘Chicago Peace’ is a favourite choice for cut flowers. To obtain large individual flowers, disbud the flower cluster by pinching out the small secondary flower buds as they appear.

Chicago Peace

SITUATION

Full sun or partial shade. Plant in a rose-bed, in a border or as a hedge.

SOIL

Thrives infertile, well-drained clay soil that is slightly acid. Deeply dig soil and add well-rotted manure or compost.

CARE

Deadhead (remove dead flower-heads) regularly during the flowering season, cutting back to an outward-facing bud. Prune annually from mid-March to early April.

PLANT HEALTH

Black spot is the most common fungal disease especially in the warm south-west of England and south Wales. Black spots with fringed edges spread rapidly, causing leaves to fall. However, urban pollution seems to keep this fungal disease in check, as does good garden hygiene. Remove and destroy infected foliage and keep the ground beneath bushes clear of debris. Spraying with a rose fungicide as soon as new growth appears can help to prevent severe attacks.
