Does this plant flower if it is leggy?

Rhododendron simsii needs bright, indirect light to bloom. If it is leggy from low light, it likely will not produce flowers.

Can I cut the stems all the way back?

Avoid cutting back more than one third of the plant at once. This can stress the plant and delay future flowering.

Why is my Sims azalea growing so leggy? Causes and fixes

Check these first

Evaluate the amount of light the plant receives daily.
Check if the plant is leaning heavily toward a window.
Look for signs of new growth at the base of the stems.

Likely causes

Insufficient light
Possible
How to tell: The stems are long and thin with large gaps between the leaves as the plant stretches toward the light.
What to do: Move the plant to a brighter spot with consistent, indirect light. If natural light is low, consider using a grow light for 8 to 10 hours a day.
Lack of pruning
Possible
How to tell: The plant looks sparse and open because it has not been shaped after flowering.
What to do: Prune back the long, straggly stems by one third to encourage bushier growth. Do this right after the plant finishes its flowering cycle.

When to worry

Legginess is rarely fatal but it makes the plant look unkempt. If the stems are very thin and weak, they may eventually snap under the weight of the leaves.

Stopping it coming back

Rotate your pot every week so all sides get equal light. Prune lightly every year to maintain a compact shape.
