How do you handle Nematodes?
1. Ignore them
2. Pull of the leaves
3. Dig up and throw out the plants

6. Put them in a hot car
7. Go all Sadam Husein, and declare chemical warfare
8. Bring them to the Hosta Society raffle
9. Other tactics.
I just dug up and threw out 20 plants and poured 4 gallons of boiling water down each hole. That took me a while.
