FAQs
My plants are healthy, but I know my plants are susceptible to disease. Can I use Organic Bio Fungicide to prevent these diseases?

As gardeners, we’ve been conditioned to be reactionary, but the best plant parents and gardeners have learned to take care of their plants and gardens in a preventative manner. We recommend using our Organic Bio Fungicide every 2 weeks for general wellness and prevention. 

What’s the difference between Organic Bio Protectant and Organic Bio Fungicide?

Both formulas have different modes of action on the plant disease, the Organic Bio Fungicide stops spore germination while the Organic Bio Protectant boosts the plants immune system to ward off the disease. However, we highly recommend mixing them together for the most powerful control and broadest spectrum. 

I just applied Arber to my plants for disease control and it just rained. Do I need to reapply?

If it rains within one hour after applying any of our organic formulas, or if the plants are not yet dried from the previous application before the rain, we’d recommend reapplying for best results.

    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.
