Oleander · Nerium oleander

Why is my oleander growing tall and leggy?

Oleanders are sun lovers that stretch out when they do not get enough light. Check your plant's location first to see if it is getting at least six hours of direct sun daily.

Check these first

  1. Assess the amount of direct sunlight the plant receives each day.
  2. Inspect the stems for signs of stretching or weak growth.
  3. Check if the plant has been pruned in the last year.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The stems are long and thin with large gaps between the leaves. The plant leans heavily toward the nearest window or light source.

    What to do: Move your oleander to a spot that receives full, direct sun for most of the day. If you are growing it indoors, place it directly in a south facing window or use a high output grow light.

  2. Lack of pruning

    Most likely

    How to tell: The plant has become tall and woody with very little growth near the base. It looks sparse and lacks a bushy shape.

    What to do: Prune back the long stems by one third after the plant finishes flowering to encourage branching. This forces the plant to grow new, fuller stems from lower down on the branches.

When to worry

It is not a health emergency, but it will continue to look sparse until you provide more light and prune it back. This is a common response to indoor conditions.

Stopping it coming back

Keep your oleander in full sun and prune it annually to maintain a compact, bushy form.

Questions people ask

Can I cut my leggy oleander all the way back to the ground?
Yes, oleanders are very resilient and can handle a hard prune. Cut it back to about 12 inches from the soil in late winter to reset its growth.
Will the leggy stems fill in on their own?
No, the existing bare stems will not grow new leaves. You must prune them to stimulate new, leafy growth.
