Preparing the raised bedsI've been using these raised beds for a while, but two years ago, I had a Japanese beetle grub infestation. I didn't know how destructive they could be so I ignored them (the "organic" thing to do, right?). Well, I ended up with very low yields last year and sickly plants.
This year, I decided to solve the problem. I dug all of the dirt out of my smaller planter and replaced it with new dirt. But the larger planter box was going to be more difficult, so my husband built me a frame for a 1/4 inch steel mesh. I dug out all the dirt and sifted it through the mesh. This helped me to pick out all of the grubs and put them into the trash. I hope to finish the job this weekend.
