We are over-run with spotted spurge. Would you suggest spraying this in both the Spring and Fall?
Prodiamine 65 WDG is a great pre-emergent for prostrate spurge only, and there is a long list of tolerant ornamentals starting on page 15 of the product label. There are several types of Jasmine, Juniper, and sedum listed as tolerant. You may want to consider using Snapshot in your ornamental beds, instead, though. This pre-emergent label lists over 300 tolerant ornamental species and will prevent several types of spurge including both prostrate and spotted spurge. You can apply either of these products in Spring or Fall, although you definitely want to apply in Spring and possibly again in mid-summer for spurge prevention. Spurge also prefers high moisture areas, so be sure you address any drainage issues to help prevent this weed from thriving. Keep in mind that pre-emergents will only prevent new plants from germinating, not kill existing plants.
