A disappointing display of flowers on rose bushes and climbers can be a result of ‘rose blindness’.Â 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
