Bulbs are the lifeblood of the border in the early part of the year. From February to early May, crocus, daffodils and tulips are the first signs that warmer days are approaching and after the emptiness of winter, the sight of them pushing through bare soil is a joy. There is an art to planting bulbs successfully, and if you’re thinking about creating a spring border display using bulbs, you need to plant them in the autumn when the soil is still warm. As well as looking beautiful at the start of the year, bulbs look spectacular when combined with other plants and grasses. Below you’ll find some useful tips on planting bulbs and four planting combinations for spring borders. And don’t forget to download Gardens Illustrated‘s bulb planting design.
A guide on using spring bulbs in borders
Order your bulbs early so you can ensure you get what you want.
Plant at the right time. Snowdrops should not be planted later than early October. Smaller, early flowering bulbs, such as scilla and crocus, should be planted in the first half of October; daffodils in late October; tulips in November, when the soil is cold; and alliums in December.
Plant in the right conditions. Tulips like well-drained soil and sun; daffodils can handle more moisture and shade.
Let the style of the garden dictate your choice of bulbs. If it’s formal, Fritillaria imperialis would be a good choice, while a woodland area would suit bluebells.
Sequence your plantings so they flower at different times: for example, crocus, muscari, tulips and scilla, daffodils, bluebells.
Better to plant too deep than too shallow – at least 15cm is good for tulips.
Better to order only a few cultivars in large quantities than a small number of many different cultivars.
Don’t worry too much about spacing. Catalogues will tell you to plant 10cm apart but I prefer a more natural look, scattering them and planting them where they fall. Tulips are strong and can grow through other plants without harming them.
Don’t braid or remove the leaves or stems of tulips if you want them to naturalise.
