Allgold

A rose that glows ‘Allgold’ lives up to its name by being one of the purest yellow roses available.

The flowers in bud are particularly well shaped, so it is a good rose for flower arranging and bouquets. It is also ideally suited to massed planting.

ANNUAL CALENDAR

SPRING

March-April:

Tread in soil around the base of mature plants that may have been rocked by winter winds, as water collecting around the base can freeze and cause damage.

Watch for aphid infestation on flower buds.

SUMMER

May-July:

During flowering, deadhead (remove fading flowers) regularly by pinching out individual flowers from clusters as they fade. When a whole cluster fades, cut back to the first bud just above a full leaf. This brings on a new flowering stem.

AUTUMN

August-September:

Prepare planting sites. Although container-grown bushes can be planted at any time of the year, this is the best time as they can make new roots before starting growth the following spring.

WINTER

October-November:

Plant new bare-root bushes. December-February:

Prune established bushes.

Planting schemes

A low-growing, compact rose such as ‘Allgold’ is ideal for massed bedding, especially as infection is not likely to be a problem with this disease-resistant plant.

This cultivar guarantees an attractive display during the flowering season.

Since ‘Allgold’ is rather formal in appearance, a formal, geometric layout for the beds often suits it best.

Keep the planting simple to achieve maximum impact. Consider unifying the design by repeating an edging of a low-growing plant such as lavender or catmint on each bed.

The rose ‘Allgold’ is a small cluster-flowered type raised by the Norfolk breeders, LeGrice Roses, in 1956. The double flowers are golden yellow and grow on long stems.

Most yellow roses are particularly prone to fungal infections, especially black spot, but ‘Allgold’ is noted for its resistance to disease. Another advantage is that, while the colour of other yellow roses tends to fade as the blooms age, ‘Allgold’ keeps its clear golden tint.

Ideal situation

Roses are sun lovers, but they do not like to bake in dry soil, so site the bed in partial shade if necessary. Avoid direct shade from trees and the poor soil below hedges. An open site facing south or southwest is ideal.

Planting and care

Dig planting holes at least 45-60cm wide and deep enough so that the bud union (the knob where the rose has been grafted on to the root stock) is at least 3cm below the soil. Break up the bottom of the hole. Mix a handful of bone meal into the dug out soil. For a bare-root plant, cut back any long or damaged roots. Fan out the roots in the bottom of the hole, fill it in and gently tread around the stem.

During dry spells, roses on sandy or chalky soil benefit from regular watering. Just let the water trickle gently around the stem. A permanent mulch (ground covering) of well-rotted compost also helps to conserve moisture.

IMPORTANT

Never plant new roses into a site which has grown roses for more than 10 years, as the soil will be ‘rose sick’ (contain organisms harmful to the feed¬ing roots of young roses). It is possible to renew the bed by removing the top 30cm of soil and replacing it with fresh soil, but a different site is preferable.

PRUNING

Careful pruning helps maintain a healthy plant. Prune ‘Allgold’ during January or February. First remove all dead and diseased stems, cutting back to healthy wood. Then remove all thin, weak stems, cutting back to stronger branches. Finally, cut out all stems growing towards the centre of the bush or any crossing branches. The aim is to create an open-centred framework of sturdy stems. Trim back remaining healthy stems to 10-15cm in length. Use sharp secateurs and cut just above an outward-facing bud. Slant the cut down and away from the bud.

Allgold

SITUATION

Plant in a sunny bed or border where the air circulates freely. This helps to promote good flowering and prevents disease.

SOIL

Roses thrive in medium soil (neither heavy or light) that is slightly acid. Dig clay soils deeply and improve by incorporating well-rotted manure or compost.

CARE

During the flowering season, remove individual blooms as they fade and shorten stems when they finish flowering. Prune in winter to promote vigour. Water in dry weather.

PLANT HEALTH

Watch for aphids feeding on new flower buds. Spray with a specific insecticide to control a heavy infestation. Later on, caterpillars may damage foliage. Spray if necessary.

BUYING ‘Allgold’ can also be bought as a climber which is much more vigorous, reaching about 4m in height. It retains the healthy foliage, but is rather shy of flowering.
