These top 10 summer flower bulbs to grow will brighten up any garden. You’ll have a colourful flowering garden for summer, from pots and containers to beds and borders. Bulbs are easy to plant and grow and will help you grow not just a colourful garden but also a wildlife-friendly garden. There are many bulbs that will attract pollinators to any size space.

When to plant summer-flowering bulbs?

Summer bulbs need warm weather and warm soil to establish and grow a root system. The ideal soil temperature needs to be around 13°C degrees. Summer flowering bulbs are usually planted in springtime, from March to May, so you still have plenty of time to get yours. Don’t try to plant summer bulbs earlier to avoid them from not growing or root rot. An easy rule to remember is if it’s time for your tomatoes to go outdoors, it is also time to plant summer bulbs.
