When to worry
It is normal for young plants to skip flowering their first year. If your plant is mature and still not blooming after moving it to full sun, it may need more time to adjust.
Stopping it coming back
Provide consistent, direct sunlight throughout the growing season and use a balanced fertilizer sparingly.
