Advice Use a soft potting technique for transplanting leaving about 1/3 of the corm exposed after watering in. Plants should be shaded temporarily in bright sunlight but prolonged shading will cause large leaf development and flower number will be reduced.
Grow on a dry regime but avoid wilting. Water early in the day to avoid foliage lying wet overnight. Good ventilation is essential.
Common pests & diseases Fusarium Wilt - sudden yellowing of the foliage and irreversible wilting.
Associated with over watering and poor hygiene.
Bacterial rot - wilting of the leaves without yellowing along with a soft corm.
Botrytis - grey mould.
Cyclamen mite - bronzing, hardening and distortion of the leaves.
Vine Weevil - soft larvae which feed on corms.
Sciarid fly - associated with wet conditions.
Botrytis - grey mould and root diseases if grown too wet.
