We just moved to upstate WA and have ALOT of clover we can't seem to get rid of. Want to prevent this clover from rearing its ugly head next year. What is best to prevent it and when to apply and any recommendation for killing what we have now? Tried weed killer for lawns but it didn't kill the clover.
Bonide Weed Beater Complete would not be a product to use for preventing clover, only in killing it as a post-emergent. Ferti-Lome Broadleaf Weed Control with Gallery would be good for preventing many types of clover. For post-emergent control, it is best to treat clover in the spring before temperatures reach 80 degrees or higher. Depending on your grass type, Q4 Plus Turf Herbicide would be a good product to use and is safe for most cool season lawns. Please refer to the product label to confirm your grass type is listed as tolerant. Application timing for pre-emergents will vary by region and the best person to ask about application timing is your local master gardener who works at your local cooperative extension office.
