  • Deadhead your rose bushes.

FEBRUARY

  • Spray for rust and check the underside of leaves for red spider.
  • Continue deadheading your roses.
  • As new buds develop, feed with a handful of 5:1:5 or 8:1:5 granular fertiliser around the base of each plant, as you would in September
  • fertiliser around the base of each plant.

  • Continue to control aphids, and spray for mildew, black spot and rust.

MAY

JUNE

  • Feed your standard roses with 3:1:5 fertiliser.

JULY

AUGUST

  • Use sprays to control aphids, thrips and bollworms.

OCTOBER

  • You should be enjoying your first flush of flowers by now. While it could be tempting to choose blooms from the back of your rose bush so the missing flowers are less noticeable, it’s best to cut roses that receive the most sunlight, as these will have the strongest stems, helping them last longer once cut.
  • Feed as for September.
  • Water regularly – each plant needs about 10 litres of water a week, especially as the weather heats up.
  • Spray buds of roses for caterpillars, bollworm eggs, fruit beetles, etc. Remember: only spray the buds when using an insecticide.
  • Check for rust on leaves and treat with fungicide if they’re affected.

  • Cut out unproductive twiggy growth.
  • Continue to water twice weekly.
  • Remove side buds from hybrid tea bushes if larger blooms are desired.
