Plant gladioli in groups at 14-day intervals to extend their flowering season, and enjoy their fabulous blooms all summer long. Height: 60cm (24"). Spread: 15cm (6").
In autumn, allow the foliage to die back naturally before lifting the corms and cleaning them of soil and any remaining stems. Dry them in a well ventilated position for 2 weeks before storing them in a frost-free location for the winter. When growing gladioli in mild areas with particularly well drained soil, it may not be necessary to lift the corms. Apply a dry mulch of bark chips or leaf mould in autumn to protect the corms from cold, wet weather.
Seeds and garden supplies will normally be delivered within the time period stated against each product as detailed above.

I have grown these before using corms from a different supplier and they were fine, though they don't usually survive the winter. However last year I bought corms from T&M and not a single one flowered.

Thompson and Morgan should really not be selling these are regular garden plants for the UK. After planting lots myself I have not had a single flower all year, after giving constant, careful attention. Reading up online I now see that this is generally the case in the UK as these are essentially tropical plants that need high temperatures and strong sun to grow. They may succeed in a greenhouse but trying to grow them outside, even in the sunniest of spots, is generally a lost cause. Buying them on this site was a total waste of money. I am not impressed with the company.
