    Great Product for Mold

    I have had issues with mold on top of the soil in my houseplants for the last year. I’ve tried cinnamon, which killed my spider plant, and neem oil which made several of my plants unhappy. Finally I tried this, not only did it work to eliminate the mold, but it made all of my plants glow with health. There leaves are glossy and healthy. I have a peace lily which I thought was on its last legs, and now, two months after first use, it is one of the healthiest house plants I’ve ever seen. It’s leaves went from a sickly yellow to now being so shiny and green it looks like plastic.

    No more fungus amongus!

    I was dealing with powdery mildew on my pea plants and before I knew it was moving to other plants in my vertical garden. Thankfully the biofungicide cleared it up in only two treatments five days apart! Now I only need to treat my plants every 10 days or so to keep everything under control. I strongly recommend using this product right from the beginning and not waiting until you have a problem. I'm using all of the Arber products both inside and outside where I grow both in soil and in hydroponics. I've used a lot of products and this is by far the best!

    I’m very satisfied so far with the products in my organic kit. The products are easy to use, and seem to be supporting the health of my house plants. I’ve included a photo of a plant that is growing better since using Arber. I’m looking forward to trying these on my outdoor plants.

    Love this product!

    I started using this on a fiddle leaf fig tree I purchased a couple months ago. It wasn’t growing new leaves, occasionally dropped its lower leaves, and mushrooms were coming out of the bottom drainage holes. I have been using Arbor’s bio fungicide for about a month now, and there is new growth on 3 branches and no more mushrooms. This stuff is amazing and I will definitely be purchasing again! It makes me want to try their other products as well.
