Amaryllis Plants & Nut Grass

Question

I have quite a few Amaryllis plants in my gardens beds and they are being over run by nut grass. I have read you can treat nut grass naturally with sugar and i was wondering if this will hurt my Amaryllis plants.

Answer 1

Unfortunately, getting rid of these pests is not easy. Hand pulling will be your best bet using natural methods. It takes persistence. There are selective herbicides that will only target the nut grass, and leave the amaryllis alone. This requires knowing the species. They are also synthetic, however.

Another option will be to dig them all up when they are resting after flowering. This can be a slowdown in growth, or dieback of leaves. Once they are dug up, you can treat the area, or boil water and treat the area daily until nothing grows. Once all weeds are killed off, you can plant again. This is the method that I recommend for true weed control. Continuous boiling water will destroy the weeds, while keeping the soil intact and without contamination.
