Check these first
- Check if the plant is getting at least 6 hours of direct sun.
- Observe if the plant has been kept cool and dry during the winter months.
Likely causes
Insufficient light
Most likelyHow to tell: The pads look thin or stretched out instead of plump and compact. The plant is not receiving the 6 to 8 hours of direct sun it needs daily.
What to do: Move the cactus to your sunniest south facing window or outdoors for the summer. If you cannot provide enough natural light, use a high output grow light for 12 hours a day.
Lack of winter dormancy
Most likelyHow to tell: The plant stays warm and active all year round. It never experiences the cool, dry temperatures necessary to trigger flower bud formation.
What to do: Keep the plant in a cool room between 40 to 50 degrees Fahrenheit from November to February. Stop watering almost entirely during these months to mimic its natural desert winter.

When to worry
It is normal for young plants to take several years before they are mature enough to produce flowers. Do not worry if your cactus is healthy but simply not yet old enough to bloom.
Stopping it coming back
Ensure the plant experiences a clear seasonal shift with bright summer sun and a cold, dry winter rest.

- How old does a Beavertail cactus need to be to flower?
- These cacti usually need to be several years old and quite large before they have the energy to bloom. Patience is key with this species.
