De-weeding my garden
I live in Riverside, California (about 60 miles east of Los Angeles).
My garden is loaded with Senecio vulgaris (common groundsel) and Euphorbia peplus (petty spurge).
When hand-weeding, what's the best way to make sure I pull all of the weeds ("ROOTS AND ALL").
After weeding, what can I apply to prevent these weeds from re-emerging? (Preen Weed Preventer doesn't work). (Note: There are shrubs and trees in the garden so I don't want to harm them).
