Do nematodes have to be putu down every year?
Do nematodes live and spread from year to year? I do not want to poison my yard for the japanese beetles. I have too many birds and bees for me to poison the soil. I have plenty of seed eaters, and have put out suet for the insect eaters, but am afraid there will be too many beetles, like last year, for them to eat. What time is best to put the nematodes down? Thank you for any help you can offer.
