Pineapple · Ananas comosus

Why is my pineapple plant growing tall and spindly?

A leggy pineapple plant is almost always reaching for more light. Pineapples are sun-loving plants that need as much direct light as you can provide.

Check these first

  1. Observe if the plant is leaning toward a light source.
  2. Measure the distance between the leaves to see if they are stretching.
  3. Check if the leaves are pale green instead of a deep, healthy color.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The leaves grow long, thin, and pale rather than thick and sturdy. The plant will lean heavily toward the nearest window.

    What to do: Move the plant to a south-facing window where it can get at least 6 to 8 hours of direct sunlight. If you do not have a sunny window, use a strong LED grow light placed 6 to 12 inches above the plant.

  2. Low light during winter

    Possible

    How to tell: This is less common for this plant, and usually happens if the plant is kept in a dim room during the shorter days of winter. The growth slows down and becomes stretched as the plant tries to find energy.

    What to do: Supplement with a grow light during the darker months to maintain a compact shape. Keep the plant in the warmest part of the house to encourage healthy growth.

When to worry

Legginess is not an emergency, but it makes the plant structurally weak and less likely to produce fruit. It is normal for the plant to grow slightly slower in winter, but it should not look stretched or thin.

Stopping it coming back

Provide maximum sun exposure year-round. Rotate the pot every week so all sides get equal light and the plant grows straight.

Questions people ask

Will the leggy leaves turn back to normal?
No, the existing leaves will stay as they are. However, new growth will be compact and healthy once you provide enough light.
Do pineapples flower indoors?
Pineapples rarely flower indoors without very intense, full-day sun. They need high light levels to bloom and produce fruit, so keep them in your brightest spot.
