They added: “Spacing depends on type and habit. Check catalogue or label details.
“If you are replacing old roses with new roses, ensure that you dig out the soil to a depth and width of 45cm and exchange it with soil from a different part of the garden, as roses are at risk from replant disease, also known as soil sickness.”
Gardeners should prune back roses in the first winter after planting, doing this crucial job in late winter or early spring. With all roses, first remove dead, damaged and weak growths.
General ongoing care involves feeding every spring as well as mulching immediately after, keeping the mulch clear of the rose stems.
