Likely causes
Insufficient Light
Most likelyHow to tell: The branches are thin, stretched out, and have large gaps between leaves.
What to do: Move the plant to the sunniest window available or outdoors in full sun. Gradually acclimate it to avoid sunburn if it has been in lower light.
Excessive Fertilizer
PossibleHow to tell: The plant grows quickly but the new growth is weak and spindly.
What to do: Stop all fertilization. Boojum trees prefer poor, rocky soil and do not need extra nutrients to thrive.

When to worry

Stopping it coming back
