Rose Blindness

Rose Blindness

A disappointing display of flowers on rose bushes and climbers can be a result of ‘rose blindness’.  The term blindness in gardening terms refers to the failure to flower and is common in daffodils that become constricted (see below).

Reasons for Poor Flowering

  • Due to environmental conditions in some years roses flower badly despite the best efforts of gardeners.
  • An empty flower case can be caused by frost damage.
  • Poor fertility in the soil and lack of trace elements and nutrients
  • Excessive shade
  • A build up of old wood and weak growths
  • Infection such as this severe case of blackspot
  • Some varieties are just prone to intermittent blindness

Avoiding & Curing Rose Blindness

  • Careful positioning of your roses in the sun without too much competition from other plants.
  • Improve cultivation to relieve stress, add humus, water regularly, apply fertilisers and fungicide if needed.
  • Reduction in the amount of old wood to encorage new healthy shoots.
  • Cut back a blind shoot by half it’s length to stimulate further growth
