one per hole.. or lets say one square foot.. is probably not considered a significant population ...

second.. they are more of a lawn problem .. did you remove lawn for your new patch ...

ONLY WHEN I WAS A LAWN WARRIOR.. DID I BATTLE THEM... oops ... i never found them to be an issue in the general garden.. yucky as they may be ,..

one per hole.. or lets say one square foot.. is probaly not considered a significant population ...

and keep in mind.. they turn into something else soon enough .. and you need to figure out if that end thingee is the real problem ...

i suppose the major pest related to such is this: https://duckduckgo.com/?t=ffnt&q=japanee+beetle+grubs&iax=images&ia=images

and if you have a lot of those.. then you should probably be treating your lawn .. rather than your berry patch ...

and i have no idea how to ID them ... any more specifically ...

my bottom line.. pick your battles.. but there is no reason to kill everything.. just because they look disgusting.. lol ... it can become very costly .. and cause you to use too much stuff ma nature might not need thrown on her ...

lets see if i am in the majority or minority on such ...

i think what i was trying to say is.. there are products you might not mind using in the lawn .... that you dont want in your food garden ...

I sprayed the grass with grass killer, then 1 month later I tilled the grass into the new raspberry rows. I guess that's why there were grubs. I wasn't that worried about 1 grub per sq ft but now since I put down leaf mulch around my raspberries I'm afraid I introduced grubs to my young plants. There was only 1 bucket that I seen the 50 grubs in, I didn't use that bucket.

Are you saying that the grubs wont be in the soil in a month because they all turn into some other kind of flying or crawling insect that will not eat my plants roots?

sure.. they will pupate and then go eat the leaves of some.. hopefully.. other plants ....lol .. sooner or later ...

Probable either Japanese beetle or June bug grubs, I dig them up here every Spring, my hen loves them.

My bream the lake got about 50 yesterday they loved them

I am finding two grubs per 5 gallon bucket today, I'm sifting by hand.

I guess it still surprises me that people say so casually, 'I sprayed the grass with grass killer than tilled the clippings into my raspberry rows.' I've been gardening for 40+ years and never used a pesticide and stay clear of synthetic fertilizers. I have aphids on my roses right now, but I see them as a meal for a lady bug that won't come to my yard if I kill them. It's just difficult for me to grasp how people still don't understand how the ecology works and don't even try to work with it. Especially when there has certainly been enough evidence that a lot of the stuff people buy and use on their garden has been shown to be harmful to people and pollinators and our water supply, etc.

I'm not trying to criticize anyone here, or start an argument. I just want to speak up and express a view that I've had for decades that has served me well and expose others to those experiences so they realize there is another way of doing things. That's all I have to say about it.
