Daffodil growing myths: a concise orientation before we get practical.

Daffodil growing myths: Quick notes

affodils are reliable and resilient but there are six daffodil growing myths that you need to know about.

With 27,000 different varieties, daffodils are one of the easiest plants to grow — and, with the right approach, you can have them flowering for decades or even centuries.

At Hever Castle, one of the top daffodil gardens in England, some species of daffodil have been growing there since Anne Boleyn’s time.

And when the American William Waldorf Astor spent millions transforming the gardens 120 years ago he planted thousands of daffodils, many of which are still growing.

So to find out what works and what doesn’t in growing daffodils, I visited Hever Castle, one of the top daffodil gardens in the UK, where thousands of bulbs create spectacular displays for their Dazzling Daffodils festival every spring.

I spoke to two leading experts – Johnny Walkers, who comes from a bulb-growing family and has won 29 Gold Medals at Chelsea for his daffodils. He has been working with Hever Castle Head Gardener, Neil Miller on the new ‘Hever Castle’ daffodil.

Between them, they’ve seen what works — and what goes wrong — in real gardens, so I asked them to bust some of the most common daffodil growing myths.

Myth 1: If daffodils stop flowering, they’re finished

Many people assume that once daffodils go “blind” (lots of leaves but no flowers), they’re past their best.

But that’s not true.

Daffodils are remarkably resilient. Johnny Walkers says that if they stop flowering, it’s usually because:

the bulbs are overcrowded
nutrients in the soil are depleted
the bulbs have become too small to flower

What to do instead:

Lift and divide congested clumps
Replant in fresh soil with more space
Or feed with a low-nitrogen fertiliser

Given the right conditions, they will return to flowering — though it may take a year or two.

Myth 2: Bigger bulbs are always better

One of the commonest daffodil growing myths is that all daffodil bulbs are large — and that bigger means better.

In reality, bulb size varies hugely depending on the variety.

Some (like ‘Tête-à-Tête’) are naturally small
Others (like large trumpet daffodils, for example ‘Hever Castle’) have much bigger bulbs

What matters most is not size, but quality.

Johnny Walkers’ advice is to choose firm, healthy bulbs from a reputable supplier, such as an online bulb supplier or a garden centre. (I think he’s suggesting that supermarkets may not be the best source of daffodil bulbs, but he was too polite to say so!)

Myth 3: You should tidy the leaves after flowering

This is one of the most damaging daffodil growing myths. My mother couldn’t wait to ‘tidy up’ the daffodils after flowering. In the end, no daffodils ever came back to flower in our garden.

Cutting, tying or braiding the leaves may make the garden look tidier — but it seriously weakens the bulb.

As Neil says, it’s like “strangling” the plant.

The leaves are still feeding the bulb after flowering, storing energy for next year’s blooms.

What to do instead:

Leave foliage to die down naturally (at least 6–8 weeks)
Resist the urge to tidy too soon

It may look untidy for a while, but it’s essential for a good display next spring.

Myth 4: Daffodils don’t need watering or care after flowering

Daffodils are often seen as completely low-maintenance — but neglect after flowering can affect next year’s results.

This is especially important for daffodils grown in pots.

Common mistake:

Putting pots aside and forgetting about them once they’ve flowered

What to do instead:

Keep watering until the leaves die back
Feed lightly after flowering
Ensure pots don’t dry out completely

Even in the ground, daffodils prefer moisture-retentive but well-drained soil.

Myth 5: Fertiliser should go in the planting hole

You’ll often see advice to add fertiliser when planting bulbs — but with daffodils, this can do more harm than good.

The bulb already contains everything it needs for its first year’s flower.

Adding fertiliser directly into the planting hole can:

damage emerging roots
reduce the bulb’s ability to establish

What to do instead:

Feed after flowering, not at planting
Use a low-nitrogen fertiliser to support next year’s blooms

🌼 Myth 6: Daffodils will thrive anywhere

Daffodils are adaptable — but they don’t perform equally well in all conditions.

Two key factors make a big difference:

Soil

They prefer neutral soil (around pH 6.5–7)
Very acidic soil can reduce flowering

If your garden is acidic (for example, if you grow camellias or rhododendrons), you may find daffodils don’t return well.

Solution:

Grow daffodils in pots with controlled compost
Or accept they may need replanting more often

Light

Full sun isn’t always ideal
Many daffodils last longer in light or dappled shade

Alongside busting these daffodil growing myths, a few practical tips stood out:

Plant bulbs deeply — about twice the height of the bulb
Avoid overcrowding — give bulbs room to grow
For a natural look, plant in clumps or scatter in drifts, not rows
Don’t cut grass over daffodils until foliage has died back

At Hever Castle, even historic plantings have reappeared after being shaded for years — a reminder of just how resilient daffodils can be when conditions are right.

Daffodils are often described as “easy” — and they are. But they’re not completely hands-off.

Most problems come down to a few simple misunderstandings:
