Skip to main content- Check the corms are healthy & firm before planting
- Plant your corms about 15-20cm deep & 15cm apart
- Plant into well drained soil & in a sunny position
- Water well during dry spells & weed regularly
- Feed with a high-potash fertiliser once the flower spikes appear
- Bamboo canes & string work perfectly for staking. Tie the stems at intervals along their length so they don’t bend from the tied point
- Watch out for insects as they can damage leaves & flowers
- Gladioli can survive outside in mild areas if the soil is well-drained & mulched
