What are autumn bulbs?

Autumn bulbs are bulbs and other underground storage organs planted during autumn, generally from September to December, to establish before winter and flower during the following spring or early summer.

When should I plant autumn bulbs?

Most autumn-planted bulbs are planted between September and December, although the ideal planting time varies between different types. Crocus, narcissus and hyacinths can generally be planted earlier in autumn, while tulips are usually planted later.

Can autumn bulbs be planted late?

Yes. Healthy bulbs can usually be planted later in the season provided the soil is workable and not frozen or waterlogged. However, planting at the recommended time gives bulbs the best opportunity to establish strong roots before winter.

How deep should autumn bulbs be planted?

As a general guide, bulbs should be planted at a depth of around two to three times their own height, although the exact depth varies according to the species and variety. Always follow the planting instructions supplied with the bulbs.

Which bulbs are best for early spring colour?

Crocus and early-flowering narcissus are excellent choices for early spring colour. They can be combined with other bulbs to create a succession of flowers through spring.

What are the best bulbs for a long season of spring colour?

Combining bulbs with different flowering periods is the best way to extend the display. Crocus can provide late-winter colour, followed by narcissus and hyacinths, then tulips and later-flowering alliums.

What are the best bulbs for planting in sunny borders?

Alliums and tulips are particularly effective in sunny borders, while narcissus, crocus and hyacinths can also be used where the soil is suitable. Choose varieties according to the available space, mature height and desired flowering period.

Can autumn bulbs be planted in shade?

Some bulbs tolerate partial or light shade, particularly where they receive good spring light beneath deciduous trees. The exact requirements vary between bulb groups and individual varieties, so always check the growing conditions recommended for the bulbs you choose.

Can I plant autumn bulbs under trees?

Yes. Early-flowering bulbs can work particularly well beneath deciduous trees because they flower before the tree canopy becomes fully developed. Crocus and narcissus are especially useful for naturalistic planting beneath trees.

Can autumn bulbs be planted in lawns?

Yes. Suitable bulbs such as crocus and narcissus can be naturalised through lawns and grassed areas to create informal spring displays. The foliage must be allowed to die back naturally after flowering before the area is cut.

Can autumn bulbs be planted in pots and containers?

Yes. Autumn bulbs are excellent for pots and containers, making them particularly useful for patios, courtyards, entrances and small gardens. Use a container with good drainage and a suitable free-draining compost.

Can different bulbs be planted together in pots?

Yes. Different bulbs can be combined in containers to create a succession of flowers. Bulbs with different flowering times and heights can be layered or grouped together to extend the display.

What is a bulb lasagne?

A bulb lasagne is a container planting technique where bulbs with different flowering times are planted in layers at different depths. Later-flowering bulbs are planted deeper, with earlier and smaller bulbs closer to the surface, creating a succession of flowers from the same container.

Can I combine alliums, crocus, hyacinths, narcissus and tulips?

Yes. These five groups can be combined to create a succession of colour from late winter into early summer. Crocus provide early colour, narcissus and hyacinths follow, tulips create a major spring display and alliums provide later architectural flowers.

What bulbs combine well with alliums?

Alliums combine particularly well with tulips and later-emerging herbaceous perennials. Their tall flower stems can rise above surrounding foliage, while the foliage of the allium itself can be concealed as it begins to die back.

What bulbs combine well with tulips?

Tulips can be combined with narcissus, hyacinths, crocus and other spring bulbs. Choose combinations based on flowering time, height and colour to create a coordinated display.

How can I combine bulbs in a garden border?

Plant bulbs in groups or drifts and combine varieties with different flowering periods and heights. Repeating the same bulbs or colour combinations in several parts of the border helps create a cohesive design.

Can autumn bulbs be planted among herbaceous perennials?

Yes. Bulbs are particularly effective among herbaceous perennials because the perennial foliage can hide bulb foliage as it fades. Alliums are especially useful because their flower stems rise above surrounding plants.

Should I remove bulb foliage after flowering?

No. Allow the foliage to die back naturally after flowering. The leaves photosynthesise and replenish the bulb's stored energy, helping it flower successfully in future years.

What soil is best for autumn bulbs?

Most autumn bulbs perform best in fertile, well-drained soil. Good drainage is particularly important because bulbs can rot in persistently waterlogged conditions. Heavy soils may benefit from improvement before planting.

How do I stop bulbs rotting?

Plant bulbs in well-drained soil or free-draining containers, avoid persistently waterlogged areas and follow the recommended planting depth. Good drainage is one of the most important factors in preventing bulb rot.

Do autumn bulbs need feeding?

Good-quality bulbs contain stored nutrients for their initial growth and flowering, but fertile soil helps support long-term performance. Maintaining healthy foliage after flowering is particularly important because the leaves replenish the bulb's reserves.

What should I do with bulbs after they flower?

Remove spent flowers where appropriate, but leave the foliage in place until it has naturally yellowed and died back. This allows the leaves to replenish the bulb for future seasons.

Frequently Asked Questions About Autumn Bulbs

When is the best time to plant autumn bulbs?

Most autumn-planted spring bulbs are planted from September onwards, with the exact timing depending on the bulb. Crocus, narcissus and hyacinths are generally planted earlier in autumn, while tulips are usually planted in October and November. For further information see our planting guide here.

Can you plant bulbs in pots?

Yes. Autumn bulbs are excellent for containers. Use a container with good drainage and a quality peat-free compost. Bulbs can be planted more closely together in pots to create a stronger display. We have lots of ideas for using bulbs in pots and containers here.

Can you plant different bulbs together?

Yes. Combining bulbs with different flowering times is one of the best ways to create a long season of colour. Crocus, narcissus, hyacinths, tulips and alliums can be combined to provide a succession from late winter into early summer. For ways of combining bulbs in the garden for the best effect, click here.

What bulbs flower first?

Crocus are among the earliest of the five main groups, often flowering from late winter into early spring. They can be followed by narcissus, hyacinths, tulips and then alliums.

What are the best bulbs for naturalising?

Narcissus and crocus are particularly useful for naturalistic planting, including lawns and areas beneath deciduous trees. Allow foliage to die back naturally after flowering so the bulbs can replenish their reserves.

Which bulbs are best for containers?

Crocus, narcissus, hyacinths and tulips all perform well in containers. Compact tulips and narcissus are particularly useful where space is limited, while hyacinths are ideal near entrances and seating areas because of their fragrance.

Can you plant alliums in pots?

Yes. Smaller alliums are particularly suitable for containers, while larger varieties need a sufficiently large, stable container because their tall flower stems can become top-heavy.

Do bulbs come back every year?

Many autumn-planted bulbs are perennial and can return for several years when planted in suitable conditions. Narcissus and many alliums are particularly reliable for repeat performance. Some tulips are less persistent and may perform best when treated as seasonal displays, depending on the variety and growing conditions.

Should bulb foliage be cut back after flowering?

No. Allow the foliage to die back naturally. The leaves are needed to photosynthesise and replenish the bulb for future growth.

Can bulbs be planted under trees?

Yes, particularly beneath deciduous trees where early-flowering bulbs can flower before the tree canopy becomes dense. Crocus and narcissus are particularly useful for this style of planting.

What is the best way to combine bulbs in a border?

Combine bulbs according to flowering time, height and colour. A succession such as crocus, narcissus, tulips and alliums can provide colour over several months rather than creating one short flowering period.
