Fusarium wilt
Also called Fusarium wilt effect, Fusarium
A soil fungus that clogs the plant's water lines. Leaves yellow and wilt, then the branch or the whole plant dies.
How to spot it
- Leaves turn yellow, often in V-shaped sections
- Wilting starts on single branches or leaves, then spreads
- Older leaves go first
- Leaves and branches die and drop
- Brown streaks inside the stem when it is cut open
Why it shows up
The fungus lives in the soil for a long time, even with no host plant around. It does best in acidic, sandy soil and does more damage when nematodes hurt the roots first. Too much nitrogen and soggy soil make it worse.
How we treat it
There is no cure once a plant is infected. We will identify it on a visit and tell you what we see. The fix is mostly cultural: remove the sick plant, fix drainage, and do not replant the same kind of plant in that spot. We will talk through options with you.
What you can do
- Remove sick plants promptly.
- Do not replant the same kind of plant in that spot.
- Fix drainage, and do not overwater or overdo the nitrogen.
