Jack's Classic 20-10-20 Citrus Feed Water-Soluble Fertilizer with Micronutrients to Provide Better Growth and Fruiting in Tropical Fruiting Plants, 1.5lbs

This is a very easy to use product. You just measure out the powder with the enclosed scoop and add to the watering can. Just a week or so after first use I can already see a noticeable effect. Plants are fully, look healthier and have many more leaves and blooms. No real negatives I can see so far. Good product.

Since I discovered this, my flowers have bloomed like never ever before. Worth every penny, and lasts a long time. And FAST results!

We weren’t sure our poor young Meyer lemon tree was going to survive. We’d planted it in full sun, watered it regularly, and had been using a different citrus fertilizer applied to the soil, but it didn’t have many leaves, and the leaves it did have kept turning yellow and falling off. I had never used a foliar fertilizer before and thought I’d give Jack’s a try as my last resort. I’ve been feeding our tree with this fertilizer for about 4 months now, 2 Tbsp. in 2 gallons of water in my watering can, applied to the leaves every Friday, with the excess falling onto the soil around the tree. And our tree is looking healthy again, with lots of new leaves and more tiny ones sprouting out! What a joy to see! (And a relief not to have to replace a $200 tree!). Highly recommended!

My orange trees love this fertilizer. A friend said they had never seen so many blossoms on an orange tree.

This product provides vibrance to trees and plants when applied correctly. Leaves become noticeably greener when the trees and plants had sufficiently absorbed the fertilizer.

Great product, easy to mix, and works well to perk up the leaves.

Good brand, just what my lemon tree needs!

I doubted it could be worth the money. When I saw the package I was certain I had been hosed. Not so! I followed the instructions, began feeding in December and followed up with small feedings every month. As you can see in the video the result was astonishing, particularly to my children who had never really seen this tree bear more than a few fruit in the 20 years it had been there. Highly recommended! Also used on pomegranate and tangerine this year - so far so good

I had my lemon tree, which I started from seed several years ago and found that it grew ok but needed some help. Some of the leaves were turning yellow, but the tree was reasonably healthy. So I decided to try the Jacks formula and was pleasantly surprised that the leaves were slowly getting a richer more vibrant green. I started with a weaker solution at first, and gradually increased its dosage. So far the tree is looking far better than it did before. I will certainly buy more when I run out - which should take some time. I would recommend this product.

Just 2 applications to my lemons and oranges and the leaf size doubled for the new growths. Expensive but application is just 1 spoon in around 4 litres of water in 7 to 10 days. So it will last a long time.

The micronutrients is the key to successful citrus fruit trees. This has it, and my orange trees love it! They look so much better since I used it.

Good

Too soon to really tell how effective this product fully is but as a foliar spray goes, it works. Within a few days the leaves went from having some yellowing to a full vibrant green color!! Time will only tell on the effectiveness of the growth of the grapefruit tree I'm using this product on. If it does, this product will go from a four star rating to a five star rating from me and from what I have seen so far, I have high hopes and confidence it will be a five star product!
