Bird of Paradise Root Rot: How to Check, Trim and Repot
Updated
Why does my Bird of paradise have root rot?
Bird of paradise is usually trouble-free, but root rot can follow overwatering or poorly drained mix. Yellowing leaves and wilting while the mix is still wet point to roots and rhizomes that have started to decay.
What to do first
Stop watering, unpot the plant and inspect the roots and rhizome. Cut away soft, dark tissue, keep firm divisions, and replant at the same depth in fresh, free-draining mix in a pot that is snug rather than oversized.
Bird of paradise (Strelitzia reginae) is a tough plant, but its roots do not tolerate sitting wet. NC State Extension says the plant is usually pest and disease free, and that root rot can occur from overwatering or poorly drained soils. The University of Hawaii’s Crop Knowledge Master lists Pythium root rot among the diseases of bird of paradise.
If leaves are yellowing or the plant is slumping while the pot is still damp, check the roots before you water again.
Signs of root rot in a bird of paradise
NC State notes that the leaves arise from underground rhizomes, so check the rhizome as well as the roots. Look for several of these together:
- Yellowing leaves while the mix is wet. UF IFAS notes that both dry and soggy conditions cause bird of paradise leaves to yellow and eventually die. The state of the mix tells you which.
- Wilting despite moist mix. University of Maryland Extension explains that root rot can cause wilting even when there is adequate moisture.
- Brown to black, soft roots. UMD describes rotted roots whose outer layer pulls away and leaves a thin thread.
- Dark or soft tissue at the base. Clemson HGIC’s houseplant disorders factsheet describes stems girdled at soil level by brown or black tissue.
- A heavy pot that stays wet for a long time, or water standing in the saucer.
Rule out the look-alikes
A struggling bird of paradise does not always have rot:
| What you see | More likely cause |
|---|---|
| Yellowing with a dry, light pot | Underwatering; water thoroughly |
| Yellow or brown spots on otherwise firm leaves | Leaf spot; NC State lists this |
| Sticky residue, white cottony tufts or small bumps | Mealybugs or scale |
| Fine speckling or webbing under leaves | Spider mites, which NC State lists as a pest |
| Few flowers after division or repotting | Disturbance; UF notes plants flower more freely when crowded and are best left undisturbed |
Split and curled leaves have their own checks in our bird of paradise care guide.
Treat the roots step by step
- Stop watering and empty any saucer or decorative outer pot.
- Unpot the plant. Large plants are heavy, so lay the pot on its side and ease the root ball out.
- Remove the old mix so you can see the roots and rhizome.
- Sort healthy from rotted tissue. Firm roots and a firm rhizome are worth keeping. Soft, dark, collapsing tissue is not.
- Cut out the damage with clean, sharp tools. Clemson advises cutting out the infected roots when only a few are affected, then repotting in sterile soil.
- Keep firm divisions if the clump is badly affected. UF IFAS describes dividing clumps into single-stem divisions. The RHS describes propagating by dividing rooted suckers.
- Replant at the same depth the plant grew before. UF IFAS advises this for divisions.
- Use fresh, free-draining mix. The RHS recommends a loam-based compost for container plants. UF IFAS notes the plant does best in fertile soil with good drainage. UMD advises against a gravel layer in the pot base.
- Do not overpot. The RHS says plants generally flower better slightly pot-bound. UF IFAS notes they flower more freely when crowded.
- Water once to settle the mix, then wait until the top dries before watering again, as UMD’s repotting guide advises.
Hold off on feeding until new leaves appear. The RHS feeding advice applies to plants in active growth.
When to start over
UMD advises throwing away severely infected plants and taking material only from healthy tissue. For bird of paradise, the healthy material is a firm division with its own roots.
UF IFAS says divisions take 1–2 years to become mature, flowering plants. A severely rotted plant may not flower for a while even if it survives.
Clemson notes that root rot fungicides are available, but most indoor gardeners will find they cost more than a new plant.
Water a bird of paradise so the rot does not return
- Growing season: the RHS advises watering freely during growth. NC State says to water freely in spring and summer.
- Winter: water sparingly. NC State says to keep plants drier in winter. UF IFAS advises watering only when the soil is fairly dry.
- Drainage: NC State recommends fertile, loamy, well-drained soil. Always use a pot with a drainage hole.
- Light: NC State recommends a well-lit, sunny spot indoors. The RHS suggests full light with shade from hot sun.
- Temperature: NC State gives night temperatures of 13–18 °C (55–65 °F).
