Troubleshooting
Ohio Spiderwort problems — and how to fix them
Ohio Spiderwort (Tradescantia ohiensis) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Leaf rust and fungal leaf spot
Yellow or brown lesions in humid conditions with poor air circulation; thin overcrowded clumps, avoid wetting foliage, and divide every 3–4 years to improve ventilation.
Slugs and aphids
Emerging spring growth and soft shoot tips are susceptible; apply iron phosphate slug bait in early spring and use a strong water spray or insecticidal soap for aphid colonies.
Excessive self-seeding
Plants can colonise large areas via prolific self-seeding; deadhead spent flowers before seed sets, or cut all stems to 15 cm (6 in) after the first flush of bloom.
