Able to kill clover that's growing throughout a bed of creeping jenny?

Depending on where you live, weed - and - feed products can be effective against clover. Scotts® Turf Builder® Weed & Feed and Scotts® Lawn Pro® Step 2 Weed Control Plus Fertilizer are good options. If you have St. Augustine grass or zoysia, use a product that won't harm them, such as Scotts® Bonus® S Southern Weed and Feed. Good luck!!

Clover is tough...to get it out you will damage the creeping Jenny..I know I did.

depending upon the amount of clover...you can make the appropriate solution of herbicide & using an artist's paint brush...brush it on the clover leaves[not every single one, but at least one per plant] when NO RAIN is due to fall, wait until the plant has greatly died back before removing it out of the soil or roots will be left behind.

If the clover is small it still has roots that can be pulled pretty easily.

I'd have a glass of wine, take a seat and start pulling! Anything is better by hand - keep the garden organic.
