Help

Hello, I am currently growing outdoors & as I was transplanting I noticed there was an abundance rolly polies I was just wondering if they are harmful to the plants. Thank you

Well that sucks. Is there any way I could get rid of them?
Most of the chemical controls are systemic in plants so those are out but Look for a grub control with Bacillus Thuringiensis . It’s a naturally occurring soil bacteria that should give some control. Also there are beneficial nematodes that can work. Do a large area where you are planting, better yet do the whole yard. Once the BT colonized the soil it’s a long term control method.

Would this work? Or there is spray. Which would you recommend?

It should you can get BT in a garden center or big box store for lawn application probably cheaper than fungus gnat control. Grubhalt or Grubgone are two brands.

Dear god put that down. That is a dust for foliage application. You want to kill grubs I the soil. There are several chemical products that go systemic in plants and kilL grubs when they eat the roots. Not bad if your raising weed only for ornamental purposes. Not so good if you want to smoke it. So really the best solution for you is, one, do nothing or two get some BT lawn treatment.
