Likely causes
Insufficient light
Most likelyHow to tell: The stems are long and thin with large gaps between the leaves. The plant looks stretched out and weak.
What to do: Move the plant to a location with full sun or bright indirect light. If growing indoors, place it directly in a south or west facing window.
Lack of support
PossibleHow to tell: The vines are sprawling on the ground or drooping because they have nothing to climb. The plant looks messy and unkempt.
What to do: Provide a trellis, stake, or string for the vines to wrap around. Gently guide the new growth onto the support structure.

When to worry
It is normal for this fast grower to stretch slightly in early spring, but persistent legginess indicates a light deficiency.
Stopping it coming back
Provide consistent, bright light from the start and install a trellis as soon as the plant begins to vine.
