Frequently Asked Questions (FAQs)

1. When should summer bulbs be planted?

Spring is the perfect time for planting summer bulbs as the risk of frost has usually passed. Plant the bulbs directly into warm soil in the garden, in the same way that you plant spring bulbs.

2. Do summer bulbs come back every year?

After flowering, the bulbs remain alive beneath the surface of the soil and simply produce flowers again during the next growing season. That's what makes them so delightful.

3. What summer flowering bulbs are there?

"Summer bulbs span tubers, corms and rhizomes. My top five are dahlias, lilies, eucomis, crocosmia and begonia," he shares. Alongside those, there are also the lactiflora varieties of peony, agapanthus, gladioli, nerine for late summer and early autumn, as well as canna and Zantedeschia, he explains.

4. Can summer bulbs be left in the ground?

Do I need to dig up my bulbs or can I leave them in the ground? Spring-blooming bulbs that are winter hardy, such as tulips, daffodils and crocus, can be left right in the ground. Summer bulbs such as dahlias, tuberous begonias and calla lilies, will not survive cold winters.
