Troika

Easy route to a striking display ‘Troika’ is an outstanding bedding rose and one of the easiest to grow.

Large, fragrant blossoms fulfil the promise of prettily pointed buds, and dark, silky-green foliage sets off the flowers to perfection.

ANNUAL CALENDAR

SPRING

March-April:

Prune and begin regular spraying against diseases and pests. Give first application of rose fertilizer.

SUMMER

May-July:

Deadhead (remove wilted flower-heads) regularly. Give second application of rose fertilizer around the base of each plant.

AUTUMN

September-November:

Plan new plantings and prepare planting sites.

WINTER

November-February

Plant new bushes and tidy up established rose-beds.

Destroy fallen leaves and other debris that can harbour disease.

Dig old mulches into the soil.

Sprinkle soil around the roots to hold the plant in position and start to refill the planting hole.

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

Finish filling in and then gently tread around the plant to firm the soil.

Apply a mulch (ground covering) of well-rotted manure to the surface of the surrounding soil.

Cultivating

Hybrid Teas bloom throughout the summer and on into late autumn. During flowering, dead head (remove wilted flower-heads) regularly by cutting back to the first bud just above a full leaf. This encourages a new flowering stem to grow.

During dry spells, regular watering is neces-sary if the soil is sandy or chalky. Always let water trickle gently around the base of the rose to avoid washing the bottom of the stem or roots bare. In heavy and clay soils, roses are fairly drought resistant and a permanent mulch of well-rotted compost will help to conserve moisture.

Container-grown plants should be kept moist but never waterlogged.

U nlike many older varieties of orange-tinted rose, ‘Troika’ is sturdy and trouble-free. It thrives in a wide range of garden environments and climatic conditions.

This Hybrid Tea rose was originally introduced by a Danish breeder and is also known as ‘Royal Dane’. It makes a stocky bush, about 90cm in height, and flowers early and freely. The blossoms are not damaged by rain and have a good scent. The foliage is dense.

The tidy nature of ‘Troika’ makes it suitable for container growing, but it is, above all, an excellent choice for planting in a formal bedding scheme.

Planting

Buy ‘Troika’ as a bare-root rose for planting in October or November. Container-grown bushes can be bought for planting at any time but it is usually best to plant in autumn as this allows the rose to make new roots before growing above ground again the next spring.

Dig a planting hole at least 45 60cm wide and deep enough to cover the union between the stock and bud (join between the rootstock and upper part of the plant) by at least 2.5cm after final firming clown.

Mix some well-rotted manure into the soil at the bottom of the planting hole, breaking up any compacted soil as you do so.

Mix a handful of bone meal into the soil removed from the hole.

Remove long or damaged roots from the plant and fan the remaining roots out into the bottom of the hole.

Prune in March when the hardest frosts are past but before the plant is actively producing new growth,

Always use sharp secateurs to make each cut just above an outward-facing bud. Angle the cut at about 30°, with the slope running downwards and away from the bud.

First, remove dead and diseased stems. Cut right back to healthy wood which appears white across the whole width of the cut.

Next, remove thin, weak stems by cutting back to the stronger-growing branches.

Finally, cut out all stems that grow towards the centre of the bush and also any crossing branches. This serves to develop an open-centred framework of sturdy stems which receive adequate light.

PLANTING SCHEMES

Troika looks excellent with paler companions such as ‘Silver Wedding or ‘Elizabeth Harkness’, both of which have a soft peaches-and-cream tint.

Edging a bed of ‘Troika’ with creamy miniature roses such as ‘Easter

Morning’ makes a real garden showpiece.

Troika

SITUATION

Full sun or partial shade. Take care not to plant in soil where other roses have grown previously. Always choose a new site or renew the soil to a depth of 30cm.

SOIL

Crumbly, slightly acid soil with high organic content. Deeply dig clay soils and add well-rotted manure or compost.

CARE

Deadhead (remove wilted blooms) regularly, cutting back to an outward-facing bud. Prune annually in mid-March-early April, hard pruning if necessary.

PLANT HEALTH

‘Troika’ is reliably hardy, with good resistance to disease. Spray at intervals throughout the summer to keep aphids down. Keep the garden clear of debris that can harbour fungal spores.

BUYING

In an exceptionally wet and windy garden where even ‘Troika’ does not do well, try the similar and yet tougher variety, ‘Johnnie Walker’.
