Recently Tony posted about how his Artichokes were under attack by slugs. Tony decided to use a slug repellant as well as an insecticidal soap. While those are both good methods to go about it I chose a different way. Like Tony my Romanesco artichoke was under attack by slugs. What I do in these slug situations is to use horticultural DE (Diatomaceous Earth). DE shreds the insects tender skin as it comes in contact with it. It is safe for humans to be in contact with it as DE only impacts small insects (Humans eat DE every time they eat flour or grains). One application resolved my slug problem and my artichokes are now slug free.
DE is excellent for use on other tender leafy greens or basically any plant that is susceptible to insect pests. Please remember that DE doesn't discern between good insects and bad insects so be aware of that. DE is a great alternative for pesticides when you don't really need them. You also have to reapply it after rainfall
