Caring for outdoor roses

The beautiful Renaissance® rose Capricia™ Poulren024(N)

Buy only healthy roses

If you want to ensure that you get a healthy plant from your chosen nursery, look at the foliage and growth and see if it looks fresh and healthy. The plants must not have withered leaves, leaves with spots or bare branches, and the roots must be fresh and healthy.

Position of roses

The best position for roses is in full sunshine or in a location that has sun for a minimum of six hours a day. Roses can be planted in normal topsoil/clayey garden soil.

Planting roses

If you buy bare-rooted roses which are usually slightly cheaper than roses in pots, planting must take place in October-November as the plant hibernates during this time and you will still be able to dig the soil before the frost sets in. Potted roses can be planted at any time of year – although it must be ensured that plants do not dry out during the first few weeks – especially in the summer.

Dig a deep hole so that the rose’s grafting place (the thick part just above the roots) is approx. 10 centimetres below the surface. Cover the roots with soil and carefully press the soil around the roots. Then water the rose thoroughly and keep it moist in the weeks following planting.

Fertilising and watering of roses

To ensure plenty of flowers and healthy plants, the roses should be fertilised three times a year – at the end of March when new shoots appear, when the roses are budding and after the first flowering.

Pruning roses

Pruning roses is, in principle, optional. But dead and old branches should be removed at the end of April as they disfigure the plant and increase the risk of disease.

The roses can be cut back to 20-30 centimetres. Cut approx. 1 centimetre above an outwardly turned leaf to ensure that the plant produces harmonious branches. Our Towne & Country roses and the Cottage roses are called ‘easy-to-grow roses’. They do not require pruning. But if they have grown too big, they can be cut right down to the ground with an electric hedge trimmer.

Some people say that branches must be bent downwards to ensure more flowers. Roses from Poulsen Roser do not need to be bent as they branch extremely well and have rigid branches that do not break. The plants also flower from the bottom of the plant right up to the top. Many other roses only flower at the top of the plant and thereby have ‘bare legs’. It therefore makes sense to compensate for this poor quality by cheating the plant to flower more by bending the branches downwards.

If large amounts of flowers are required throughout the summer, the dead flowers just above the first set of five leaves should be removed to enable more new flowers to appear quickly.

Roses in pots outdoors

Roses can be planted in pots outdoors without any problem. Ensure that the rose is planted in a suitably large pot. Use good, nutrient-rich soil when planting out the roses. Remember that the pot must never be allowed to dry out, but it must not be soaking wet either. The soil should be replaced every spring. Potted roses should be cared for in the same way as roses planted in beds.
