Start Planting Bulbs: Easy Spring Colour for Pots and Borders

Spring may feel a long way off, but autumn is the time to start planting many of the bulbs that will bring your garden back to life after winter. A little planning now can give you cheerful colour in pots, borders, pathways and front gardens next spring.

This week in our Monday Garden Guide, we are focusing on easy spring colour for pots and borders, including daffodils, crocus, hyacinths, tulips, alliums and simple bulb-planting ideas for every space.

Why Plant Spring Bulbs Now?

Spring-flowering bulbs are planted while they are dormant, before they burst into growth the following year. Once planted, they can quietly develop roots underground through autumn and winter, ready to flower in spring.

Bulbs are a brilliant choice because they are:

• Easy to plant

• Great for pots and borders

• Suitable for small gardens

• Perfect for adding early colour

• Useful for filling gaps before summer plants take over

• Available in a wide range of colours, heights and flowering times

The RHS recommends planting spring-flowering bulbs in autumn. Daffodils, crocus and hyacinths are best planted by the end of September where possible, while tulips are usually planted later, in November.

Best Spring Bulbs to Plant

There are many bulbs to choose from, depending on the space you have and the look you want to create.

Daffodils

Daffodils are one of the most reliable spring bulbs. Their bright yellow, cream, white or orange flowers bring cheerful colour to borders, lawns, containers and front gardens.

They are best planted in early autumn, ideally September, and prefer a sunny or lightly shaded position with well-drained soil. Avoid planting daffodils in waterlogged soil or deep shade.

Daffodils often return year after year when grown in suitable conditions.

Crocus

Crocus flowers are small but full of impact. They are excellent for pots, borders, gravel gardens and naturalising in grass.

Their early flowers can also provide a useful food source for pollinators when fewer plants are in bloom.

Plant crocus in autumn, ideally by the end of September. They look best planted in groups or scattered naturally through grass or borders.

Hyacinths

Hyacinths are loved for their strong fragrance and dense flower spikes. They work beautifully in pots near doorways, paths and seating areas where their scent can be enjoyed.

Garden hyacinths can be planted outdoors in autumn for spring flowering. Choose a sunny or lightly shaded position with well-drained soil or compost.

When planting in containers, make sure the pot drains freely, as bulbs can rot if left in waterlogged compost.

Tulips

Tulips bring elegant spring colour in a huge range of shades, from soft pastels to bold reds, oranges, purples and near-black tones.

Unlike many other spring bulbs, tulips are usually planted later in autumn. The RHS recommends planting tulips in November. This later timing can help reduce the risk of disease problems such as tulip fire.

Tulips prefer a sunny, sheltered position and free-draining soil. In containers, they can create a striking display on patios, balconies and front steps.

Alliums

Alliums produce rounded flower heads on tall stems, adding height and structure to late spring and early summer borders.

They work well with perennials, ornamental grasses and other spring bulbs. Many alliums are also attractive to bees and other pollinating insects.

Plant alliums in autumn in a sunny position with well-drained soil.

Muscari

Muscari, often called grape hyacinths, produce small blue, purple or white flower spikes. They are excellent for edging paths, filling pots and underplanting taller bulbs.

They spread well in suitable conditions and can provide reliable spring colour year after year.

Plant Bulbs at the Right Depth

Planting depth is important. If bulbs are planted too shallowly, they may dry out, be disturbed by wildlife or flower poorly.

As a general guide, plant bulbs at around three times their own depth, with about one bulb’s width between them. The RHS recommends planting most bulbs at three times their depth and one bulb width apart.

For example, a bulb that is 5cm tall should usually be planted around 15cm deep.

Always check the packet instructions, as some bulbs have more specific requirements.

Plant most bulbs with the pointed end facing upwards. If you are unsure which way up a bulb should go, plant it on its side and it will usually find its own way.

How to Plant Bulbs in Borders

Bulbs are one of the easiest ways to add spring colour to borders.

To plant bulbs in borders:

1. Choose a suitable position for the type of bulb.

2. Remove weeds from the area.

3. Loosen compacted soil with a fork.

4. Dig a hole or trench to the correct depth.

5. Place bulbs with the pointed end facing upwards.

6. Space them according to the packet instructions.

7. Cover with soil and firm gently.

8. Water after planting if the soil is dry.

For the most natural effect, plant bulbs in groups rather than single straight lines. Daffodils, crocus and muscari often look best in drifts or clusters.

When planting around existing perennials and shrubs, take care not to damage established roots.

How to Plant Bulbs in Pots

Bulbs are perfect for pots and containers, especially if you have a patio, balcony, courtyard or front doorstep.

Choose a container with drainage holes and fill it with suitable peat-free compost. The RHS recommends using a container with drainage holes and peat-free multi-purpose compost when planting bulbs in pots.

For best results:

• Use a pot deep enough for the bulbs you are planting.

• Make sure excess water can drain away.

• Plant bulbs at the correct depth.

• Water after planting.

• Place the pot in a suitable position outdoors.

• Check occasionally through autumn and winter so the compost does not dry out completely.

Bulbs dislike sitting in waterlogged compost, so avoid leaving pots permanently standing in water.

Try a Bulb Lasagne

A bulb lasagne is a layered container where different bulbs are planted at different depths. This can give a longer display from one pot, as different bulbs flower at different times.

For example, you could plant:

• Tulips in the deepest layer

• Daffodils or hyacinths in the middle layer

• Crocus, muscari or iris reticulata near the top

Add compost between each layer so the bulbs are not sitting directly on top of one another.

The RHS recommends using two or three layers of bulbs in one pot for a fuller container display.

Choose bulbs with flowering times that follow on from each other for the best effect.

Create Colour Themes

Bulbs are available in so many colours that it is easy to create a display that suits your garden style.

You could try:

• Yellow daffodils with blue muscari

• White hyacinths with purple crocus

• Pink tulips with white narcissi

• Orange tulips with deep purple alliums

• Cream, apricot and soft pink bulbs for a gentle spring display

• Bold red, yellow and purple for a brighter look

Repeating the same colours across pots and borders can help the whole garden feel more coordinated.

Plant Bulbs for Pollinators

Early spring flowers can be valuable for bees and other pollinating insects when food is still limited.

Good choices may include:

• Crocus

• Snowdrops

• Muscari

• Species tulips

• Alliums

• Early daffodils

Where possible, choose single, open flowers that allow insects to reach pollen and nectar.

Avoid using pesticides on open flowers, as pollinators may be visiting them.

Naturalise Bulbs in Grass

Some bulbs can be planted in lawns or grassy areas to create a relaxed, natural look.

Crocus, snowdrops, daffodils and muscari can all work well in grass. The RHS recommends planting bulbs in grass in autumn, placing them at a depth of around three times the bulb’s height.

For a natural effect, scatter the bulbs and plant them where they land.

After flowering, allow the leaves to die back naturally before mowing. This gives the bulbs time to build up energy for the following year.

Aftercare for Spring Bulbs

Once bulbs are planted, they need very little attention.

Water newly planted pots if the compost is dry, and check containers occasionally during long dry spells. Bulbs in the ground usually need little watering unless the soil is very dry after planting.

After flowering in spring, remove faded flower heads from daffodils and tulips if you want to prevent seed formation. Leave the leaves in place until they turn yellow and die back naturally.

Do not tie, knot or cut off bulb leaves too early. The foliage helps feed the bulb for next year’s flowers.

Bulbs in pots may need feeding after flowering if you want to keep them for future years. Use a suitable liquid feed and follow the instructions on the product.

Common Bulb Problems to Avoid

A few simple steps can help bulbs perform well.

Avoid:

• Planting into waterlogged soil

• Planting too shallowly

• Leaving bulbs stored for too long

• Cutting leaves off too soon after flowering

• Using pots without drainage holes

• Allowing container bulbs to sit in water

• Planting damaged, mouldy or soft bulbs

Squirrels may disturb tulips and crocus. You can help protect newly planted pots by covering the surface with chicken wire or mesh until growth begins, making sure it is secure and safe for wildlife. RHS guidance notes that squirrels may dig up and eat bulbs, particularly tulips and crocus.
