Daffodil blindness
Daffs that come up with only foliage, and no flowers, are known as blind. This is more common in bulbs that have been in the ground for more than a year.
Poor soil lacking in nutrients can also cause narcissus blindness. Daffodil bulbs in pots should be given a fresh source of nutrients each year – replace at least half of the compost in the pot. If they are in the ground, mulch the soil with well-rotted horse manure to enrich it.
Another reason for blind bulbs is overcrowding; if bulbs have become congested, lift and divide them, replanting into fertile, well-drained soil or compost.
Poor drainage or poor quality bulbs can also be to blame. Another problem could be removing the foliage of the daffodil when deadheading – only deadhead the stems, leaving the foliage to die back completely before cutting.
Narcissus bulb fly
If your daffodils fail to come up, or produce foliage but no flowers, you may have bulb fly. To be sure, you’ll need to dig up a bulb and check for the blub fly maggots or larvae that feed on the bulb.
Planting narcissi in exposed places helps reduce the likelihood of attack, as bulb fly likes drier, sheltered areas.
Why are my daffodils not flowering?
Daffodil blindness can affect some bulbs and lead to daff foliage with no flowers. Or it may be narcissus bulb fly.
Why are my daffodils growing in September, October, November?
Bulbs may have been planted too early and with our changing climate they may send up leaves early in the season. A cold spell will stop them in their tracks and they’ll start into growth again in late winter.
Planting at the correct depth will also help reduce the impact of variable autumn temperatures.
Will snow kill my daffodils?
I’ve never had a problem leaving daffodil bulbs in the ground over winter. But you do need to mulch deeply to protect them from the coldest weather – it’s like giving them a duvet for winter.
Why are my daffodils so short?
Some varieties of daffodils are shorter than others. If the growth looks stunted, it could be that they have been infected by a virus, if there is evidence of this the bulbs should be discarded.
Why are my daffodils falling over?
Bad weather – heavy rains and strong winds – can cause stems to bend. Another reason could be shallow planting; make sure the bulbs are planted a depth that’s three times the length of the bulb.
