When planting patio roses, choose a frost-free spell if doing so in winter and make sure the soil is workable. Dig a hole roughly twice as wide as the roots and mix in plenty of composted organic matter; a top-dressing of general-purpose fertiliser or a dose of Rose Rootgrow can help encourage strong root development and reduce replant disease.
Remove the rose from its pot and gently spread out the roots, placing the plant in the hole so the bud union sits at soil level—use a flat tool, like a spade handle, to check the height. Backfill carefully, firm the soil gently, and water well to settle the plant.
For potting up, use a similar approach with a suitably sized container and free-draining potting mix, such as a loam-based John Innes, ensuring the bud union is level with the soil surface. Keep the container in a sunny spot and water regularly to keep the soil evenly moist.
Feed all roses with a specialist rose fertiliser each spring and apply a mulch of composted farmyard manure, keeping it away from stems. Little pruning is needed; in late winter or early spring, remove any dead, damaged, or weak stems and cut back over-long stems to fit the space. Deadhead spent flowers as they fade to encourage more blooms.
