    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.

    Saved my Collection

    This product saved my Collection or African Violets from a bad outbreak of Powdery Mildew. I’m really happy I found a organic product that is safe for House Plants. The directions were clear and easy to follow.

    -Thank you :D

    bio fungicide

    I`ve had a huge and ongoing problem with mold/fungus infestation for the past 3 years, which is somewhat overwhelming since I have at least 80 plants, all in containers. I had tried several fungicides, to no avail, and I lost many plants. I was at my wit`s end and thought I`d have to give up on having a pollinator garden, but then I discovered Arber and thought I`d give it a try----I loved the ingredients, and it`s safe to use. I`ve used it now for over a year, and it`s made a huge difference in all the plants. The fungal infection isn`t entirely gone yet, but with repeated applications I`m making noticeable progress in eradication---it`s just something I have to be very diligent in applying, and it`s alot of work! Luckily, I love working with my plants/garden, and the rewards of having pollinators visit a healthy garden are priceless! Arber is the ONLY input that worked and is safe, and I`m so grateful for this company. I`ve saved many of my beloved plants using this excellent product, and I will continue to use it. Many thanks to you, Arber! Brenda M
