Can I trim the leggy leaves?

It is best to leave the leaves alone until they turn yellow and die back naturally. The plant needs those leaves to store energy for next year's flowers.

Will leggy grape hyacinths still flower?

They might still produce flowers, but the stalks may be weak and prone to flopping over. Improving the light levels will help the next set of blooms stand tall.

Why is my grape hyacinth looking so leggy? Causes and fixes

Check these first

Assess the amount of direct sunlight the plant receives each day.
Check the temperature of the room where the plant is kept.
Rotate the pot if the stems are leaning toward one side.

Likely causes

Insufficient light
Most likely
How to tell: The stems stretch out and become thin or floppy as they reach for a light source. The foliage may also look paler than usual.
What to do: Move the pot to a spot that receives full sun or at least 6 hours of bright, direct light daily. If you are growing them indoors, place them in a south facing window.
Excessive warmth
Possible
How to tell: The plant grows too quickly in a warm room, causing the leaves to become long and weak. This often happens when bulbs are kept in a room that is too hot for their natural cycle.
What to do: Keep the bulbs in a cooler area, ideally between 50 to 65 degrees Fahrenheit. Cooler temperatures encourage compact, sturdy growth rather than stretched stems.

When to worry

If the stems are so weak they cannot stand up at all, the plant may not have enough energy to bloom. It is normal for the foliage to start dying back naturally after the flowering period ends.

Stopping it coming back

Provide plenty of bright light from the start and keep the environment cool during the active growth phase.
