Bulbs to Plant in April

Flowering Bulbs in April

April is one of the best times to get planting. The soil is warming up, the worst of winter is behind you, and summer flowering bulbs planted now will reward you with blooms right through the season. Whether you're filling mixed borders, topping up containers, or starting fresh, there's plenty to work with this month.

Quick wins in April:

• Ideal for borders, pots, and any gaps that need summer colour
• Most bulbs establish quickly once the soil starts to warm
• Great for building a staggered display that keeps flowering from early summer into late summer

What Bulbs Can You Plant in April?

April opens the door to a wider range of summer bulbs than earlier in the spring. The soil is more workable, night frosts are becoming less frequent, and conditions suit bulbs, corms, and tubers that need warmth to get going.

In April, look out for bulbs that:

• Are listed as ready to plant now (check each product page)
• Prefer free draining soil or well drained soil with added organic matter
• Suit containers if your ground is still heavy or slow to warm

Top 5 Bulbs for April Planting

1. Dahlia tubers: A garden staple for good reason. Plant tubers with the growth points facing upwards in a sunny, sheltered spot and you'll have bold blooms from midsummer right through to the first frosts of autumn.
2. Gladiolus corms: Tall, striking stems with a long season of colour. Plant corms in full sun with good drainage and stagger your planting across a few weeks for more flowers over a longer period.
3. Eucomis (Pineapple Lily): An unusual and eye-catching choice for borders or large containers. Give it a warm, sunny position and well drained soil, and it'll produce its distinctive flower spikes through late summer.
4. Begonia tubers: Reliable, versatile, and brilliant for pots, hanging baskets, and borders in partial shade. A great choice where you need consistent colour without full sun.
5. Crocosmia corms: Fast to establish and tough once in the ground. Hardy varieties suit mixed borders well and produce vibrant arching stems of colour from midsummer, coming back stronger year after year.

Planting Tips for April Bulbs

Spring weather is still unpredictable, so a bit of preparation goes a long way.

Check drainage first: Free draining soil is important for most bulbs. If yours is heavy or compact, mix in some compost or organic matter, or plant in containers with good drainage holes.

Plant at the right depth: The general rule is 2-3x the height of the bulb, corm, or tuber. Always check the product page for anything specific.

Orient correctly: Where relevant, make sure bulbs and tubers are planted the right way up, i.e., growth points or shoots facing upwards, roots facing down.

Water in after planting: Give everything a good soak once planted, then ease off and let the soil dry slightly between waterings. Waterlogged roots are the most common cause of rot.

Watch for late frosts: If cold snaps are still forecast, cover new growth with a light mulch or move pots under under cover or into a greenhouse overnight.

Aftercare Made Simple

Once shoots are showing, summer bulbs are fairly low-maintenance. Keep the soil just evenly moist, never waterlogged, and rotate containers occasionally so growth stays upright rather than leaning towards the light.

Bulbs in beds will largely look after themselves as long as the soil drains well and has a bit of compost or organic matter worked in. Feed lightly once growth is active (containers need this more than borders), deadhead spent flowers to extend the display, and let foliage die back naturally at the end of the season so the bulbs can store energy for next year.

Frequently Asked Questions

Can I still plant spring flowering bulbs in April? 

Spring flowering bulbs like daffodil bulbs, iris bulbs, and anemone bulbs are generally planted in autumn for a spring display, so April is too late for most of them. April is the month to shift focus to summer flowering bulbs that will carry the colour through the warmer months.

Do summer bulbs planted in April flower the same year? 

Yes, that's one of the best things about planting summer bulbs in April. Given a warm, sunny spot and well drained soil, most will establish quickly and be in bloom by midsummer. The earlier in the month you get them in, the sooner you'll see flowers.

Should I use pots or plant directly in the ground in April? 

Both work well in April. If your soil is still cold, heavy, or poorly drained, pots and containers give bulbs a better start. Once the ground is warm and workable, direct planting is fine for most hardy varieties.

How long will April-planted bulbs take to flower?

Most summer flowering bulbs planted in April will bloom from midsummer, with many continuing into late summer or early autumn. Check our individual product pages for expected bloom times.
