you could pull all the canes and roots manually, take some boiling water and kill them if you want to kill them naturally......they could come back with next to no root as it is amazing how much root is needed to start again, hope that helps.

Hate to dig, as that will leave holes, and we're not strong enuf any more to level it out!

Glyphosate

Thanks to both of you!

I wish raspberries would grow like weeds where I live, but no such luck. I can't get any raspberry plants to survive. Summers are too hot and dry. The fact we have almost no winter chill may also be a factor.

these were dug out of a neighbor's patch over 30 years ago, stuck in holes in the grass in fall, and some years are loaded, some years the Japanese beetles get most of them. I can't keep the weeds out anymore....most of our yard is going back to grass like it was 60 years ago......

Repeated mowing will kill plants but it might require an entire season. You should use a brushog mower and keep mowed close to ground.

Thanks for that info!
