    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.

    Roses are blooming

    This year I bought my first rose bush. But soon after the rose bud were turning brown without even opening. After a quick Google search it said it most likely had a fungus and needed treatment. Arber was the first product that kept popping up. I’ll be honest I bought into it because the packaging. I’m an aesthetic girlie. Anyway, once I receive the product I stayed consistent treating the rose bush for 10 days. I didn’t think I would see blooms again this year but with the heat wave and sun and probably feeling healthy it decided to bloom! I’m beyond excited and very impressed with the product! I don’t normally right reviews but when something works this good, it’s deserved.

    Safe to use

    I felt safe using this fungicide on my vegetables, especially tomatoes. It kept the blight away which has been a consistent problem for me for years. I would highly recommend this product to those gardeners who garden organically and safely.

    Used it for a month every 2 weeks and my plants are a lot healthier

    Used it every 2 weeks for the last month and can see the difference. Late march when when it started to warm up hear in California, i notice tiny crawling insects on my monsteras, pothos and aloe vera plants. I sprayed and water these and cannot see a single crawlies on my baby plants. Im pretty impressed

    A great addition!

    I love Arber’s products. I’ve used them in the past with great results and it’s also helpful to keep things on hand just incase you need them.

    I thought the $25 price point was high, normally I buy their products for $15. The normal bottles are 8oz and while I couldn’t find the exact amount in this bottle, it’s definitely much bigger than the normal bottles (see picture comparing my normal orange food bottle to the bigger purple bottle).

    I hadn’t noticed before but their bio protectant (green bottle) isn’t for indoor use but this one is. Good to know! I’ll be using this one instead now for my indoor plants.

    I definitely recommend this product.
