Gladioli Bulbs FAQs 

Take a look at some of the frequently asked questions we receive from those looking to buy Gladioli Bulbs in the UK. You can contact our Customer Service Team or browse our general FAQs for further advice.   

When should I plant Gladioli Bulbs? 

Gladioli corms are best planted outdoors from March to May once the soil begins to warm. For a longer flowering display, plant corms at intervals over several weeks. Gladioli typically flower from summer into early autumn, depending on the planting date. 

How do I plant Gladioli Bulbs? 

Plant gladioli corms in fertile, well-drained soil in a sunny position. Place the corms around 10-15cm deep and space them approximately 10-15cm apart. Water after planting and keep the soil moist during dry periods. Taller varieties may benefit from staking to support their flower spikes in exposed locations. 

Can Gladioli Bulbs be grown in pots? 

Yes, gladioli grow very well in containers. Use a large pot with good drainage and a quality compost. Compact varieties are particularly well suited to container growing, while taller varieties can create an impressive focal point on patios and terraces. 

How long do Gladioli flower for? 

Gladioli produce elegant flower spikes throughout summer, with individual blooms opening gradually from the bottom of the stem upwards. Planting corms in succession every couple of weeks can help extend the flowering season and provide colour over a longer period. 

Do Gladioli Bulbs come back every year? 

Gladioli are perennial plants, but many varieties are not fully hardy in colder areas of the UK. After flowering and once the foliage has died back, corms can be lifted, dried and stored in a cool, frost-free location over winter before replanting the following spring. 

Where can I grow Gladioli Bulbs? 

Gladioli are ideal for borders, cottage gardens, cutting gardens and patio containers. They thrive in a sunny, sheltered position with fertile, free-draining soil. Their tall flower spikes make them excellent for adding height and structure to summer displays. 

Which Gladioli variety should I choose? 

The best gladioli variety depends on the display you want to create. Available in shades of white, yellow, orange, pink, red, purple and bi-colours, gladioli can complement both traditional and contemporary planting schemes.
