[Retlaw]

I've been composting for over 40 years, and never put potato or Tomato stems or leaves in the composters.

Potato blight & other diseases, also affects tomato plants and any spores don't seem to die.

If you look at Tomato stems after all the Toms have been picked the will appear brown, dusty and rotten. I sterilise the greenhouse and all the pots with Jeyes fluid every spring, and never use the same growing medium again for spuds or tomato's

Burn them.

Retlaw.
