A rugged rose for difficult gardens
Known as the ‘hedgehog rose’ because of its prickly, the hardy rugosa rose is at home in gardens by the sea where sandy soil and salt air would defeat many other roses. It is also the ideal choice for gardens in cold climates.
Complete planting of bare-bushes.
Cut out any dead or straggly wood on existing bushes.
If it is grown as a hedge, cut back 1-2 main shoots hard to encourage new growth from ground level.
Keep new plants well watered until they are fully established. Spray against any pests and diseases if natural methods do not control them.
Prepare planting sites by digging the soil deeply and incorporatingor well-rotted manure. Plant -grown rugosas at anytime, but take care not to disturb their .
Plant new bushes.
Bare-plants from a nursery should be planted immediately.
Remove any clusters of hips on existing shrubs which have been damaged by foraging birds.
Many rugosas are grafted onto rootstock rather than their own. It is essential that the bud union (the knobbly join) is at least 2.5cm below the soil surface after planting to protect it from frost.
Rugosa roses flower repeatedly. Those with single or semi-doubleproduce huge red hips, but double make none. They can all be grown as shrubs or hedges.
Rugosa roses come from a very hardy species that grows wild on sand dunes in coastal regions of Siberia and Japan. It now grows naturally along the coast of Britain, but only its hybrids suit growing in the garden.
Planting and care
Prepare a bare-root plant by trimming away dead or damaged roots and top growth. Then cut back the branches to about 10cm from the bud union (the knobby protuberances where the grafted rose branchesfrom the root-bearing wood).
Make a planting hole at least 45cm deep and 60cm wide. Loosen soil at the bottom with a fork and scatter over a handful of bone meal. Add another handful to the rest of the dug-out soil.
Spread the plant roots in the bottom of the hole. Half fill it, then carefully tread in the soil around the plant. Shake it gently to work in the soil around the roots. Completely refill the hole and firm in the soil by treading around the.
Rugosas make a good dense thorny hedge if planted on their own.
They can also be combined with common hedgerow plants like hawthorn and field maple to make a colourful tapestry effect. The hybrids ‘Alba’ and ‘Scabrosa’ are especially good for this purpose.
