Will pruning help it flower?

Light pruning can encourage new growth, but heavy pruning often removes the stems where flowers would form. Stick to shaping the vine in late winter.

Does it need special soil to bloom?

Coral vine is not picky about soil, but it does need good drainage. It blooms best in average to poor soil rather than overly rich, amended garden beds.

Why is my Coral vine not flowering?

Check these first

Observe the plant for 6 hours to see if it stays in full sun.
Check if nearby trees or structures are casting shade on the vine.
Review your fertilizer schedule for high nitrogen content.

Likely causes

Insufficient Sunlight
Most likely
How to tell: The vine is growing long, thin stems with large gaps between leaves. It looks healthy but shows no signs of flower buds.
What to do: Move the plant to a spot that receives at least 6 to 8 hours of direct sun daily. If it is in a container, relocate it to a south facing wall or open garden area.
Excessive Nitrogen Fertilizer
Possible
How to tell: The plant has very dark, thick foliage but refuses to set buds. This happens when you use a high nitrogen lawn fertilizer nearby.
What to do: Switch to a bloom booster fertilizer with a higher middle number, like a 10 to 30 to 20 ratio. Apply this once in early spring to encourage bud formation.

When to worry

It is normal for young vines to focus on root and stem growth for their first year. Worry only if the plant is mature and has had full sun for an entire season without blooming.

Stopping it coming back

Ensure the vine has a sturdy trellis in a wide open, sunny location from the start.
