Growing roses in containers is ideal for small gardens or where space is limited, such as on a patio or terrace. Not all roses will thrive in containers, so it is important to choose the right type, such as a patio or miniature rose.
Only a few roses are tolerant of being grown in containers, as roses generally have long shallow roots for anchoring the plant and searching out moisture and nutrients. As long as deep containers are chosen, a good show of blooms should be achieved.
The best roses for growing in containers are the patio and miniature types, which can be grown in fairly small but deep pots 23-35cm (9-14in) deep. You could also try growing less vigorous, more compact ground cover and climbing roses, but use larger containers with a minimum depth of 30-45cm (12-18in).
The best compost to use is a loam-based John Innes No 3 to which 10 to 20 percent multi-purpose compost or very well-rotted manure may be added for richness. Position the container before filling with compost as it may be too heavy to move once planted up.
Roses love sunshine and should receive sun for at least half the day. However it is important that container-grown plants do not dry out or they will become prone to powdery mildew. If possible position the container so that it is shaded for part of the day, leaving the plant itself in full sun.
Ideally pot up plants in November using bare-root plants, but container-grown plants will do as well, and can be potted up any time between October and April.
- Drainage: Keep the pots raised on feet and add a drainage layer of gravel at the bottom to ensure good winter drainage
- Feeding: Roses use up food reserves quickly and grow better if top-dressed each spring with a granular rose fertiliser. Additional feeding may be required as per the manufacturer's recommendations. Avoid feeding after August as soft growth may be damaged by cold winters
- Mulching: Mulch with a 5cm (2in) top-dressing of well-rotted garden compost or manure to help retain moisture and enrich the compost
- Top-dressing: Every second year, remove the top 5cm (2in) of compost and replace with a fresh layer

Mulches and mulching
Patio and miniature shrub roses have been bred with container cultivation in mind. There is even a range of miniature patio climbers, reaching a height of about 2m (6½ ft). Some varieties of ground cover roses and climbers are also less vigorous and more compact. Half standards (roses on a trunk), reaching a height of about 1.5m (5ft) can be used for a formal effect.
