Late blight came early this year
First brown lesions on the outdoor plants on 24 July, nine days after a week of warm, wet nights. By the 30th every plant outside the lean-to was affected.
What I did: stripped the fruit that had started to turn, binned the foliage rather than composting it, and left the plants under cover alone. Those are still clean.
For next year
- Outdoor tomatoes only in the bed by the wall, where the overhang keeps the leaves dry.
- One blight-tolerant variety alongside the usual ones, to see whether it is worth the flavour.
- Wider spacing. 45 cm was too tight for airflow.
