Taking care of the garden roses

A rose for life-long pleasure


Nolina roses are bred, selected and grown for you with the utmost care and passion. We have watched your rose grow from a small cutting into a mature plant that you can enjoy for years to come. But your rose can't do this without your loving devotion and care.

Caring for your rose

Here are some tips on planting and caring for your Nolina garden rose.

Planting | where, when and how

Nolina garden roses can be planted directly in the soil or in large pots or containers for your patio or balcony. Plant or stand your rose in a spot that receives at least six hours of sun a day.

When planted in the garden, your rose will also survive the winter. If your rose is in a pot, protect it from frost by covering it with straw, a jute bag, bubble wrap, etc. If you protect your rose in the winter, make sure it can still breathe and that moisture is not trapped inside the wrapping.

Container-grown roses can be planted out at any time of year except during freezing weather. To achieve the best and most beautiful results, we recommend planting garden roses in groups, preferably with three or five of the same variety per square metre.

Step-by-step plan
  1. Select a spot where the rose will receive enough sunlight and has plenty of space to grow and for air to circulate.
  2. Dig a hole at least 50 cm in diameter and 50 cm deep.
  3. Put a layer of rose compost into the hole.
  4. Place the rose in the hole, making sure the root ball remains as intact as possible.
  5. Fill in the space around the root ball with soil and shake the rose carefully back and forth so that the soil comes into contact with all the roots. Then tamp down the soil firmly.
  6. ater the rose regularly in the first month after planting, and make sure the root ball doesn't dry out later on.

Planting | where, when and how

It is important to prune roses. Pruning keeps them growing properly, encourages flowering and keeps them young and healthy. The best time to prune your roses back is in March before the leaves emerge. You can also prune them later but they will flower later. It is not advisable to prune roses earlier than March as night frosts can freeze young shoots and kill them. So don't prune your roses until the risk of daytime frosts has passed. Pruning your roses before March can also make them more vulnerable to black spot and powdery mildew.

Pruning methods vary according to the type of rose. Here are pruning instructions for different types of roses:

  • Prune shrub roses back to 10 cm (Castle┬« and National Parks) or back to 20 cm (Renaissance┬«) above the ground so that they will produce new shoots in the spring and bloom profusely again in the summer.
  • Prune climbing roses (such as Courtyard┬«) just enough to retain the shape and health of the plant.

Good to know

Avoid planting your rose in soil where roses have been grown previously because it could suffer from rose replant disease - poor growth caused by nematodes in the soil attacking the roots. This problem can be avoided by planting African marigolds in the same spot or by digging out 60 cm of soil and replacing it with new soil.

Feeding and diseases

Nolina garden roses grow rapidly so they need feeding. We recommend fertilising Nolina roses with cow manure pellets or special rose fertiliser in the spring and then again in June. This will increase your roses' resistance to pests and diseases. Special rose fertiliser is available from your local garden centre. We also recommend applying new rose compost. If your soil is sandy, your roses will need feeding more than roses grown in rich clay soil. For neutral or acid soils you can also add an annual dose of lime to the soil where your garden roses are planted to increase the pH. If you follow these recommendations, your Nolina garden roses will continue to produce a dazzling flower display year on year.

Black aphids

Your roses may be attacked by black aphids. An aphid infestation on roses doesn't look great, and aphids can also block the flow of sap and transmit diseases.

Prevention

Planting other flowering plants between your roses, such as herbs like sage or lavender, will attract a variety of beneficial organisms and ensure a natural balance between prey and predator.

Control
Here is an eco-friendly way of controlling aphids:

  • Use a garden hose to spray the aphids off the roses. Be sure to spray upward from under the plant so that the rose suffers the least possible water damage (broken leaves). The best time to do this is in the morning so that the plant can dry off during the day.
  • You could also remove the aphids by hand. This helps to discourage a new infestation, as the odour of dead aphids keeps other aphids away.

Aphids also have certain benefits, however. They serve as food for ladybird larvae, each of which can gobble up as many as 100 aphids a day. In turn, the larvae serve as food for birds.

Black spot disease

Black spot disease is a stubborn fungal disease that causes dark purplish, brown or black spots on the leaves of roses, starting in late spring. Later in the season, the infected leaves can turn yellow and fall off. Black spot can also occur on the young stems of the rose.

The damage to the leaves means that the rose will have less energy to survive the winter and for its growth spurt in the spring. This results in less growth and fewer flowers the following season.

Prevention

Prevention is better than cure. There are several ways to prevent or limit damage from black spot:

  • Plant your roses in full sun with plenty of room for air to circulate.
  • Don't water your roses over the leaves but onto the ground around them.
  • Regularly remove fallen leaves, especially in the winter; fungal spores will survive the winter in among the fallen rose leaves on the ground and will reinfect the rose in the spring.
  • Mulch your roses with a layer of tree bark or cocoa shells.

Control

If your roses become infected with black spot, there are several ways to control it:

  • Remove infected leaves from the roses.
  • Thoroughly clean any tools after using them on infected roses.
  • Wear sturdy disposable gloves so that other roses will not come into contact with the fungus.
  • If your roses are severely infected, treat them with a fungicide until autumn. Your local garden centre will stock eco-friendly products that you can use.

Powdery mildew

Powdery mildew is a common fungal infection that affects garden roses. It can be identified by the whitish-grey mould on the leaves, stems and flowers. Powdery mildew mainly occurs during warm weather when there is some moisture present (dew, for example).

Prevention

    Prevention is better than cure. There are several ways to prevent or limit damage from powdery mildew:
  • Water well in dry weather.
  • Make sure air can circulate freely round your roses. Still, damp air is perfect for the development of powdery mildew. This is also why it's better not to plant roses too closely together.
  • Powdery mildew can also be prevented by spraying horsetail tea over the roses before they become infected. It is high in silicic acid, which increases the plant's resistance to this fungus.

Control

If your roses become infected with powdery mildew, there are several ways to control it:

  • Spray the infected plants with a systemic fungicide.
  • Dust the plants with sulphur.
  • Cut off infected parts of the plant.
