False indigo bush · Amorpha fruticosa

Why is my False indigo bush growing leggy?

A leggy False indigo bush has long, bare stems with leaves only at the tips. This is almost always a reaction to a lack of light or a need for a good trim.

Check these first

  1. Observe how much direct sun the plant gets.
  2. Check if the stems are reaching toward a specific direction.
  3. Look at the base of the plant for new buds.

Likely causes

  1. Lack of light

    Most likely

    How to tell: The stems are stretching out and reaching toward the nearest light source. The plant looks sparse and weak.

    What to do: Move the plant to a sunnier spot. If it is already in the sun, it may need to be cut back to encourage fuller, bushier growth.

  2. Lack of pruning

    Possible

    How to tell: The plant is old and has grown very tall with no foliage near the base. It looks woody and unkempt.

    What to do: Perform a rejuvenation prune in early spring. Cut the stems back by one third to half their length to force new growth lower down.

When to worry

Legginess is rarely fatal, but it makes the plant look unattractive. It is time to act if the plant is falling over under its own weight.

Stopping it coming back

Prune your shrub lightly every year after it flowers to maintain a compact shape.

Questions people ask

Can I prune it all the way to the ground?
It is better to prune it back in stages over two years. Cutting it to the ground all at once can stress the plant too much.
Is it normal for it to lose leaves at the bottom?
As the plant ages, the lower branches naturally become woody and lose leaves. Regular pruning helps hide this by encouraging new growth.
