Hey everyone! I've been running a small flower farm for the past three years, but this year I'm suddenly facing a double whammy with root aphids and root knot nematodes. I'm looking for effective strategies to combat these pests next season, especially as I'm planning for my hardy annuals. I've heard these pests can be particularly tough to manage, so any advice or tips you have would be greatly appreciated! Thanks for your kindness as I'm still learning the ropes of farming!

Definitely explore using beneficial nematodes and mycorrhizae to help boost your plant’s health. I've had luck with beneficial nematodes earlier in the season. Just remember to check the soil regularly and consider crop rotation to help manage pests. Wishing you success with your flower farm!
It sounds like you might lack biodiversity in your soil. Have you considered using neem seed meal and compost teas, especially aerated vermicompost tea? A soil test could help you understand what's going on so you can improve your soil over the winter. It could make a big difference!
Unfortunately, once you have root aphids, controlling them becomes more important than total eradication. I had root aphids in my indoor garden and struggled to get rid of them even after starting fresh. The best solution I found was a product called Ancora—doing a root drench every 2-4 weeks kept them at bay. Good luck!
For root knot nematodes, I found that planting French marigolds, especially Tagetes patula, can really help. They put out compounds from their roots that deter nematodes, but you need to plant them solidly and let them grow for about 60 days before planting your main crops. I’ve done this with my marigolds—and it seems to improve the situation! Also, check out this resource for more details: [Marigold Study](https://ccmedia.fdacs.gov/content/download/10848/file/nem050.pdf).
Thanks for the tip! I’ve read that getting rid of soil might be necessary, but it’s tough since they’ve overrun my field. Really appreciate your suggestion!
