Down To Earth All Natural Fertilizers Organic Acid Mix - 4-3-6, 5 lb | Plant Food for Blueberries, Raspberries, Azaleas, Camellias, Rhododendrons, Hydrangeas, Evergreens and Acid-Loving Plants

I've been using this Down To Earth Organic Acid Mix on my blueberry plants, and it's doing a fantastic job. The plants look healthier, have put on great growth, and I'm getting excellent berry production. I like that it's made with natural, organic ingredients and is formulated specifically for acid-loving plants like blueberries. It's easy to apply, and I've noticed my plants seem much happier since I started using it. If you grow blueberries, raspberries, or other acid-loving plants, this fertilizer is definitely worth trying. I'll continue using it because the results in my garden speak for themselves. Highly recommended!

Northeast US zone 7. Last year I bought some potted blueberries, and they seemed ok at first, but by April they were struggling. I used acidic potting mix, fish fertilizer, chelated iron. No matter what I did, I swear those blueberries were constantly on the verge of death. I know they have some specific requirements but to my knowledge I had done everything I could. I bought this plant food when I initially got them, and I started using it in the early summer. They were looking pretty rough and one of them actually died before I started using this food on it. In two weeks, their sickly reddish leaves shifted to a deep green. It started sprouting new growth by the end of the month. Within a couple months they were vibrant, bushy, and doing amazingly. I’m convinced that whatever is in this food saved my plants! I did nothing else and they just bounced back. They made it through their first winter fine, and I fed them early this season, and now I see multiple clusters of berries on them! They went from the verge of death to making berries in their second year! I would highly recommend this product, and if you ever had troubles growing blueberries and think you did everything else correctly, give this fertilizer a try. Idk how but it works. As an aside, I also use this to feed my blackberries this year and they’re absolutely exploding with flowers like I’ve never seen. Going to be a heft fruit harvest this year

Down To Earth products are awesome when you are looking for top quality, organic suplements for your plants. This stuff works, like all the products I have purchased from Down To Earth. I would, without reservation (and have), reccomended their products. Value for money is there when you factor in the quality of what your plants are getting and thus, if an edible, what you are getting. It helps growth of your plants without doubt. There is no real smell to it, as long as you are a few inches away from it. Otherwise, yes, you can notice a smell of something. It's not a smell that would make you feel sick or anything though. It's just there. If you are a gardener, I know you have smelled Waaayyy worse than this stuff. As far as durability, I thought about this, and honestly, I don't think it applies to this product. However, the box is of sufficent durability to contain the product inside of it's clear plastic bag inside the box. Don't get the bottom wet though, as it could give way when you pick it up and you could have a mess on your hands.

Very small amount

This stuff is amazing. I started my blueberries 3 years ago in the ground and amended the soil with this, but the berries were very unhappy. To be honest, our soil is clay covered in landfill (bay mud we call it) and the top 18" of dirt does not hold onto nutrients well. After 2 years, I dug them up in late fall and put them in containers, so I could control the soil and location more easily. I put them in a sunier spot as well as amended the soil heavily with this product. Last summer I had my first flowers and a modest crop of blue berries. This year i have been really dilligent about following the instructions on the box (fertilizing in NorCal in January, March and now May) and wow, what a difference! All 3 bushes (3 different varieties) are now covered in berries. i cannot wait for when they are ready to eat. I highly recommend this product for container gardening of blueberries. My volunteer parsley is also very happy sharing the pot with one of the blueberry bushes. My gardenia is not so happy.

Works on Camilla plants and blueberries very well. Box instructions are good. Don’t overuse or over fertilize. I buy a small box every Spring and let 1/4-cup dissolve in a bucket and drench the root area monthly all summer and Fall. The garden veggies get a diluted dose during the late Summer too when growing slows down.

This so far seems to be good. I live where most soils are alkaline. needed to add to the soil for my blueberries.. not sure if the added water or this fertilizer or both , but my little blueberry plants are starting to thrive. Live about 9K elevation, cold in winter..In the middle of a drought again. hope to give my plants a better start. The plants have added more leaves and started growing VERY exciting have been pampering these little blueberry plants for a couple years and they either died or were stunted.

I haven’t noted much change in my blue berry plant after fertilizing.

within days I noticed a huge difference in the health of my blueberry plants. They loved it. Will be getting more for sure!

I guess I didn't realize that it was a super small box. But for $35 plus tax you would think it would of been a regular size box of fertilizer. But nope. Its tiny. There is about a cups worth of fertilizer in the box. I feel completely ripped off. Won't be buying this again ever. Way overpriced!

I ordered this August 2023. I just brought it out to use today and after applying to my 3 blueberry plants I realized it expired in April 2022. For $70 this is inexcusable.
