When to Plant Spring Bulbs in the UK: Autumn Planting Guide

Most bulbs that flower in spring are planted in autumn. Daffodils, crocuses and hyacinths are best planted earlier in the season, preferably by the end of September, while November is a good time to plant tulips. The right timing depends on the bulb, your garden conditions and the instructions supplied with it. Here’s how to plan your planting and give the bulbs a good start.

When should you plant spring bulbs in the UK?

Use this calendar as a starting point, then check the instructions for your chosen variety. Flowering times can shift with the weather and where you live.

Bulb	Usual planting time	Usual flowering time	What to remember
Daffodils	Early autumn, preferably by the end of September	Late winter to spring, depending on variety	Plant before the ground becomes cold and difficult to work.
Crocuses	Early autumn, preferably by the end of September	Late winter to early spring	They work well in groups where their small flowers will be seen.
Hyacinths	Early autumn, preferably by the end of September	Spring	Check the variety’s instructions, especially for container displays.
Tulips	November	Spring, often later than crocuses and early daffodils	Choose a site with good drainage and follow the variety’s planting depth.

These are bulbs grown for spring flowers. Bulbs planted in spring for summer colour are a different job. For a wider look at what to do around the garden as the planting season begins, see our September gardening jobs.

Why are spring bulbs planted in autumn?

Autumn planting gives spring-flowering bulbs time to establish roots before they produce leaves and flowers. “Spring bulbs” describes when they flower, which is why the planting date can seem surprisingly early.

There is no single perfect planting day. A daffodil bulb and a tulip bulb may both flower in spring, but they do not have identical preferred planting times.

Is it too late to plant spring bulbs?

If you missed the recommended date, check the bulbs before giving up on them. Firm bulbs without signs of rot may still be worth planting promptly in workable soil or a suitable pot. Results are less predictable after a long delay: some bulbs may flower later, produce a smaller display or fail to flower in their first year.

Tulips are normally planted later than daffodils and crocuses, so a November planting is part of the usual plan rather than a missed deadline. Avoid digging into frozen or waterlogged ground. If your bulbs came with variety-specific instructions, follow those first.

How to plant spring bulbs in beds and borders

You do not need complicated equipment. The main things are a suitable position, the right planting depth and soil that will not stay waterlogged.

Check the bulbs. Choose firm bulbs and discard any that are soft or showing signs of rot.
Choose the position. Check the light and soil conditions recommended for the variety. Many popular spring bulbs, including daffodils and tulips, prefer a sunny position with good drainage.
Prepare the soil. Remove weeds and loosen compacted soil. If you are creating or renewing a planting bed, ProBlend Beds & Borders Topsoil may be relevant; check that the finished growing conditions suit your bulbs.
Plant at the right depth and spacing. A common guide is to place bulbs at around two to three times their own height beneath the soil surface, with space between them. Follow the instructions for the species or variety you have bought.
Put the bulb the right way up. The pointed shoot end usually faces upwards, with the flatter basal plate and roots facing downwards. If the shape makes this unclear, check the supplier’s guidance.
Cover and firm gently. Replace the soil without pressing hard on the bulbs. Water if the soil is dry or the bulb instructions call for it; avoid leaving the planting area waterlogged.

Groups of bulbs usually make more of an impression than a few planted far apart. You can arrange them before digging so you can see how the display will look from a path or window.

Can you plant spring bulbs in a gravel garden?

Yes, suitable spring bulbs can grow in a gravel garden, but they need to be planted in suitable soil beneath the gravel. Decorative stone is a surface covering, not a replacement for a growing medium. The bulb still needs the right planting depth, drainage, light and room for its shoots to emerge.

Move the gravel aside, dig into the soil and plant the bulb according to its instructions. Replace the soil, then spread the gravel back without leaving a heavy pile directly over the planting spot. Make a note of where you planted the bulbs so you do not disturb them when working in the border later.

If there is a weed-control membrane beneath the gravel, do not place bulbs on top of it. They need an appropriate planting opening and access to the soil below. Check the membrane’s guidance before altering it, and think ahead about where shoots and leaves will emerge each year.

Will daffodils grow through gravel? They can emerge through a suitable decorative gravel surface when properly planted in soil underneath, but success depends on the bulb, the depth and weight of the covering, drainage and any membrane present. A thick layer of stone or an intact membrane across the planting spot may obstruct growth.

Where drainage needs attention, Professional Horticultural Grit is one material used in suitable soil or compost mixes. Check the needs of your bulbs and the condition of your soil rather than assuming grit alone will solve a persistently wet site.

Planting spring bulbs in pots and lawns

Bulbs in pots

Choose a pot with drainage holes and a suitable peat-free growing medium. GravelMaster’s Multi Purpose Compost is an option for containers; check whether your chosen bulbs need a different mix or added drainage material. Plant at the depth recommended for that bulb, water after planting as needed, and keep the compost moist rather than waterlogged while the bulbs are growing.

For more general container advice, see our guide to planting flowers in pots and containers.

Bulbs in lawns

For a natural-looking display, scatter suitable bulbs over the area and plant them in the soil where they fall. Replace the turf or soil after planting. Once the bulbs have flowered, let their leaves die back naturally before mowing that part of the lawn; the foliage helps support the following year’s growth.

Why didn’t my spring bulbs flower?

There may be more than one reason, but these are useful first checks:

Planting time: Bulbs stored for too long or planted well after their recommended window may give a poor first display.
Planting depth: A bulb planted too shallowly or too deeply may struggle. Check the variety’s guidance.
Drainage: Soil or compost that remains waterlogged can cause bulbs to rot.
Bulb condition: Soft or damaged bulbs are less likely to grow well.
Aftercare: Cutting leaves back while they are still green can affect flowering in a later year.

Check the conditions for the particular bulb before changing the whole planting area. If you are working through a broader autumn garden checklist, our autumn gardening guide covers other seasonal jobs.

Frequently asked questions

When should I plant daffodil bulbs in the UK?

Plant daffodil bulbs in early autumn, preferably by the end of September. If you have missed that window, check that the bulbs are sound and plant them promptly when the ground is workable, without relying on a full first-year display.

When should I plant tulip bulbs?

November is the usual recommended month for planting tulip bulbs in the UK. Follow the instructions for the variety and avoid waterlogged ground.

Can I plant spring bulbs in November or December?

November is a normal planting time for tulips. Daffodils, crocuses and hyacinths are generally better planted earlier. Sound bulbs found late in the season may still be worth planting in workable soil or pots, but flowering is less certain.

Can bulbs grow through gravel?

Some suitable bulbs can emerge through a decorative gravel covering when they are correctly planted in soil below it. The stone layer must not be excessively deep, and an intact membrane over the planting spot can block their growth.

Which way up do you plant a bulb?

Usually, the pointed shoot end goes up and the flatter basal plate goes down. Check the instructions if your bulb has an unusual shape or you cannot tell which end is which.

Can you plant spring bulbs in pots?

Yes. Use a container with drainage holes, a suitable growing medium and the planting depth recommended for the bulb. Keep the compost moist when needed, but not waterlogged.

Start with the bulbs you want to grow, check their individual planting instructions and prepare the soil or containers before you plant. You can also browse GravelMaster’s current bulb range, checking each product’s flowering season and planting guidance before choosing.
