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!

Great stuff, my orange trees love it.

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.

I picked up a small lemon tree from Home Depot and wanted to make sure it actually survived and grew well, so I decided to try this fertilizer. I’m honestly impressed with the results so far. After using Jack’s Classic 20-10-20 citrus feed and following the recommended mix with water, my tree started looking noticeably healthier, the leaves became greener and it just looked a lot more lively overall. What I like about this fertilizer is that it dissolves easily in water and is simple to apply, which makes it great even if you’re not an expert gardener. Citrus trees can be a little picky with nutrients, so having something specifically formulated for them really helps. And the price is good compared to other brands. It’s still early in my lemon tree journey, but this definitely feels like it gave my plant the boost it needed. If you’ve picked up a citrus tree like I did and want to help it thrive, this fertilizer is definitely worth trying.

Tried to return this, unopened, and I am being charged almost $7 to send it back. Terrible customer service, but worth having on hand in case banana prices skyrocket. I might keep it for emergency. 1 cup Red Wiggler worm frass 1 cup Mushroom Compost 1 Gallon Water 3 tablespoons brown sugar (add banana peel if citrus), vigorously stir in air 3-5 times in a 24 hr period. Dilute to plant needs, up to 300% more fruit! I feel that this should be a free return.

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’ve been using this on a couple citrus plants, including an orange tree and a few I grew from seed. Whenever the leaves start looking a little pale, feeding with this perks them right back up within a month or two. My orange tree especially seems to love it. Once the growing season kicks in it starts pumping out flowers like it’s trying to impress the neighbours. It mixes easily and a little goes a long way, so the container will last me at least a couple years. If your citrus plants are looking a little sad, this stuff definitely helps turn them around.

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.

Great for citrus, yes, but also amazing for pansies, petunias, and other iron loving annuals. I use this since Dynagro is hard to find.

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.

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!
