Check these first

  1. Observe how many hours of light the plant receives daily.
  2. Check if the plant is leaning toward a light source.
  3. Measure the distance between the leaves on the stem.

Likely causes

  1. Insufficient Light

    Most likely

    How to tell: The stems stretch out with large gaps between the leaves. The plant leans heavily toward the nearest window.

    What to do: Move your plant to a brighter location with bright indirect light or partial sun. Rotate the pot every few days to ensure all sides get equal exposure.

  2. Excessive Heat

    Possible

    How to tell: The plant grows quickly but looks thin and weak. The leaves may appear smaller than usual.

    What to do: Move the plant to a cooler spot away from heaters or direct afternoon sun. Ensure it has good air circulation to keep the stems sturdy.
