how do i get rid of liverwort in my nursery?

Answer 1

Liverworts are surely one of the worst to get rid of when growing potted plants in nursery situations. It becomes labor intensive and expensive when you're trying to clean up your pots only to have them re-infested again within a few weeks.

I spent many months trying to find a reasonable way of controlling moss and liverworts in situations such as yours and found that using a product called "Cinnamite" was most effective. Cinnamite is a synthetic cinnamon oil based product used to control diseases such as powdery mildew and pests such as mites and aphids. It really does smell like cinnamon and in concentrated solutions will cause some irritation to your skin.

I'm not sure what kinds of plants you're growing but I'd recommend that you conduct a small test to determine if your plants will tolerate the product or not. You'll find that you can achieve better control when spraying your plants in warmer weather versus cool temps.

I conducted a word search using Yahoo and found the following dealer selling Cinnamite (Hydro-Organics Wholesale [phone]) but I'm sure you'll be able to find another dealer closer to where you live.

Hope this was of some help to you. GOOD LUCK!

Hi, I have another solution for you.

Spray to the dripping point over the top of the liverwort as it begins to green up in the early spring, (we did it in late February) with a 50/50 solution of plain old vinegar and water. I sprayed it over dormant perennials successfully at this strength, it did no damage to my plants and killed off the liverwort great.

I caution you that spraying this on stuff you have green and growing may damage the foliage of your crop. I test sprayed it on a few things and it burned most of them. But if the liverwort is thick enough the spray will not even touch the soil.

I got rid of a bad infestation of liverwort in my nursery in one season and one major application. I went to a Meijer's store and bought a pallet of white vinegar cheaply to do it. I no longer have a liverwort problem and it hasn't been back for years due to the scarcity of spores.
