- Check if the tree is reaching toward a light source.
- Reduce the amount of fertilizer you are using.
Likely causes
Insufficient light
Most likelyHow to tell: The branches stretch out with large gaps between the needles. The tree looks sparse and weak instead of dense and full.
What to do: Move your tree to a spot that receives full sun for at least 6 to 8 hours a day. If it is indoors, place it directly in front of a south facing window. You may need to use a grow light if natural sun is unavailable.
Excessive fertilizer
PossibleHow to tell: The tree grows very fast with soft, thin branches that cannot support their own weight. This often happens when using high nitrogen fertilizers.
What to do: Stop fertilizing for the rest of the season. Use a balanced, slow release fertilizer only once in the early spring if needed. Focus on providing more light to encourage stronger growth.

When to worry
It is a concern if the tree looks thin and weak, as it needs a sturdy structure to grow tall. Some spacing between branches is natural as the tree matures.
Stopping it coming back
Keep your giant sequoia in a location with full, direct sunlight throughout the day. Avoid over fertilizing to prevent weak, forced growth.

Questions people ask
- Will my giant sequoia fill out if I give it more light?
- Yes, providing more direct sunlight will encourage the tree to grow denser and stronger. It may take a full growing season to see significant improvement.
- Does this plant flower?
- Giant sequoias do not produce flowers, but they do produce cones. They generally do not produce these until they are very old and tall, so do not expect them in a home setting.
