Feed Your Trees... and Create A Lush Paradise Around The Yard!

Tree Secret® tree fertilizer formerly known as Save-A-Tree is a biologically correct (non-synthetic) fertilizer that has been created specifically for enhanced tree success. Our small batch, extra potent blend of readily available tree nutrients are exactly what your trees, plants, and bushes need to revitalize and look great for years to come. The competition doesn't come close!

Nitrogen found in most chemical lawn fertilizer is largely responsible for the unnatural rapid growth that weakens trees by thinning their protective cell walls; this opens the door for disease, wind damage, and bug infestations...

Plants and bushes need the same nutrition as slow growing trees. Give your yard a serving of this ultra potent, undiluted, carbon based fertilizer and watch in amazement as your trees thrive and your landscape transforms into a lush paradise.

Excellent results on all trees, bushes, and evergreens! Use 2 times per year to save a dying tree and 1 time per year to maintain good tree health.

Happy trees have less problems. This stuff works.

Why Buy Tree Secret® Tree Fertilizer

Forty years of experimentation lead to the product we now call Tree Secret®; this one of a kind tree fertilizer is a fermented blend of over 60 pure ingredients that create a special nutrient cluster which allow the tree to more easily absorb the vital nutrients needed to be high quality, strong, and problem free.....applying Tree Secret® is very similar to the process we see in nature when a tree feeds on the nutrients from composted leaves found on the forest floor.

When you apply Tree Secret® vitamins for trees you are doing much more than tree fertilizing; you are feeding it all the nutrition that the tree needs to be happy from the roots on up. Tests by microbiologists at Boise State University showed that 24 hours after tree fertilizing with Dr. JimZ®, there was an increase of 70 percent in beneficial bacteria in the soil. After a week, there was a 400 percent increase. This organic matter in the soil sets the stage for solid trees with beautiful color that yield increased amounts of delicious fruit.

We call our nutrients Biologically Correct because they are designed to stimulate microbial life in the soil and supply nutrients at a biological level. When your trees recieve nutrients at a biological level everything improves!

Traditional nutrients for trees are aimed at quick growth. “You can force-feed a plant by applying high doses of water-soluble fertilizer, and get a 10-foot tall rose bush. But the quality of the roses may not be what you want. Plants like roses may become more susceptible to aphids, because rapid growth means thin cell walls, and it is easier for the aphids to attack. Today's organic gardeners understand this.” - Jos Zamzow

The solution to weak trees and over-fertilized bushes is to feed them with the proper nutrient clusters they need to heal themselves and strengthen their immune system (yes, trees and bushes have immune systems too). So, if your trees and bushes look like they could use a little help, or if you just want to make your beautiful yard even more stunning.... there is nothing better than Tree Secret® nutrients for trees. This is mother natures premium cocktail for extraordinary results!

The story of Tree Secret® began more than 20 years ago when Boise nursery owner Jim Zamzow, whose friends affectionately dubbed him “Dr. Jim” because of his constant experimentation, started giving customers at his Idaho nursery a brown liquid organic fertilizer in used two-liter soda bottles.

Tree Secret was so successful, especially for growing fruit trees and improving soil in the vegetable garden, that customers soon had to bring their own bottles if they wanted more of the nutrient rich super fertilizer. By mid-summer the 55-gallon drum that contained the experimental batch of vitamins for trees was empty.

Last year customers bought more than 90,000 gallons of Tree Secret®... .and we have now officially sold over 1 million units. We feel good that we have been able to help so many people with tree nutrients over the years. It is our goal to help make the world a better place by providing the best possible alternative to chemical fertilizer.

Use in your yard for stronger trees, robust bushes, and beautiful perennials! Use in your garden for big, delicious fruits and vegetables!

Lived Up To The Hype!

"The internet is full of miracle tree tonics and liquid fertilizers that promise to promote rapid growth, root system expansion, and improve tree health. Dr. JimZ’s Tree Secret actually does this.I initially bought it as a last-ditch effort to save a Japanese Cedar that suffered from a great deal of browning anddying foliage over the winter.I was nervous about using fertilizer to promote rapid growth on a weakened tree. I was impressed with the idea of an undiluted, biologically correct, organic tree fertilizer that focused on providing nutrients for long-lasting tree health.After a few weeks, I was so impressed with the results that I bought two more gallons.I’ve so far used it on six trees with great results, but none so dramatic as the initial Japanese Cedar. I've already bought sevenmore gallons for fertilizationthisfall and make this a regular part of my tree maintenance for struggling tree or those where I’m seeking to promote long-term growth beyond what I feel traditional fertilizers can provide.Tip: I’ve found out through as support email that using Tree Secret once a year is good to promote growth, while doing so twice a year (in Spring and Fall) is ideal to save a weakened tree." - Alexander A.

Tree Secret Helped Grow A Thick Tree Barrier IN Backyard

Remarkable Growth!

"I got these trees green giant arborvities put in back in 2018. I started using the Tree Secret fall of 2019. By spring of 2020 I could see the results. The last picture is spring of 2022 after using the Tree Secret every early fall. By spring time every year I see remarkable growth. My trees are a barrier because there's a house right behind me. When I go into the yard now the neighbors behind me can't see me. The landscaper recently put in trees on the side of my yard. They are quite small. He said whatever you did for those trees in the back, do for these!" -Troy T.

Reviews

Amazing results

"I used this product on several of my trees after a harsh winter . This holly had deer damage and I was going to replace them as they’re at my front door and looked awful. I tried this and I cannot believe how they have come back! You can see the bottom was almost gone in 2 months the transformation is unbelievable. I have also used on burning bush that was transferred and we are starting to see some results. The product is pricey especially if you have larger properties with lots of tree but it does work!"

Liquid Magic

"I purchased dr JimZ tree secret after seeing constant ads on facebook and in particular, an add showing an evergreen that recovered after using this product. I took my chances last spring with an Alberta spruce that was almost dead and it recovered amazingly. This spring I bought several bottles for new trees I’ve planted and some old ones that weren’t doing great. It’s absolutely visible the difference and even my husband reminds me to buy it yearly. I also tried houseplant magic on my indoor plants, and it also worked like magic. A photos that was stringy with very little leaves revived and leaves started popping up throughout the stems. Truly works."

— Angela R. (5/5)

My trees look amazing!

"I live in a high altitude desert environment that is very hard on all my trees. I used Tree Secret and wow what a difference. My sycamore tree look pathetic and I figured I would need to cut it down soon. Last year at this time it was producing spare and small leaves. This year it's a healthier tree. All my trees are more vibrant in their colors."

— Shawn C. (5/5)

Beautiful trees

"This product is absolutely phenomenal. I used it according to the directions on 5 foot tall, arborvitae in my backyard, which was almost dead. Now the arborvitae is thriving. Green and lush. I also used the product according to the directions on an Alberta Spruce in my front yard. It had been slowly dying over the past two years, one application of your product. It is now green, lush in doing wonderful. Great product highly endorse"

— James D. (5/5)

Great product

"This product works well. This is my second year using it this year. I noticed I had some light brown for me on all my trees. Thought they had not enough water for too long a time. But they came out of it. I had a doctor Jim’s again and they came out of it and they look wonderful. I will keep using it."

— Gary A. (5/5)

This Works!

"I bought a Fragrant Tea Olive shrub that had some obvious pest damage to some of the leaves. The shrub was 5ft tal at time of purchas. Even after preparing the soil on the perfect site, the leaves began falling off, and the shrub didn't look like it would survive. Even after removing all fallen leaves and amending with rich compost, there was still no change. I've given the shrub 2 doses (1 cup each, one month apart) and will wait until fall for the next dose. Two months in, the shrub is bouncing back. A new flush of leaves is visible all over, and it has stopped dropping leaves altogether. This product really works!"

— Sandy W. (5/5)

I bought 5 pines a

"I bought 5 pines a few years ago , 4 are planted in a row , and doing wonderful. The fifth one was put away from them on its own . It was doing great ( not nearly as good as the 4 others) noticed it going brown coming out of winter and into spring . I did as directed but didn’t really see much change, unfortunately."

— 1Kathleen R. (5/5)

This is my second time

"This is my second time using it. I have a few trees that have some brown spots. Last year I believed it cleared them up so I'm doing it again this year. So far, I have spots but it's only been a week since I used it. I like the products and believe they work. I never give reviews. Now if you send me a coupon based on taking this time, that will make 6 stars."

— David S. (5/5)

Great for fruit trees

"My cherry, Italian plum, and banana, especially banana tree have grown and sprouted saplings from using this product. All but one pine trees have filled in and gotten taller. Very pleased with the results and ease of use."

— Ray A. (5/5)

From the brink of death!

"Last year we put in two gorgeous Canadian Hemlock trees. Over the winter, the deer devastated them so badly we were just going to take the $1000 loss. But then i saw your ad on Facebook and purchased Tree Secret. I Am truly in shock! It may take two years but there is new growth all over the bare tree! I LOVE IT!"

— Lynette D. (5/5)

Q&A

is Tree Secret non-toxic to animals?: Tree Secret is all natural and toxin free. It is safe to use around animals and pets :) We hope you give it a try!
I have arborvitae and boxwoods in containers on my deck. Three are less than 1" thick - would I use a much smaller amount since they are in containers vs in-ground? Thank you!: When applying to trees that are in containers it is important to be careful and not over-apply. It is a good rule of thumb to apply at half rate and then reapply if needed. Hope this helps!
I have a massive hedge of 4 10 ft tall by 6 ft wide yews that are around 40-50 yrs old. Since they are almost like trees, would I use the shrub measuring guide or the tree measuring guide to determine how much fertilizer to apply?: It would be best to measure them as you would a tree :) Hope this helps!
Hi, My Tree Secret bottles are in my shed. The weather got down to between 10 and 32 for several weeks this year (Zone 8A, Memphis, Tn 2024-25) will they still be useable. I want to feed my trees in a couple weeks.: Absolutely! Tree Secret can freeze and get hot without any problems. The nutrients are good for 3 years :) Hope this helps!
What is the dosage for white pines and balsams at mature stage. I have 36 trees. (tree secret): The amount needed for best results depends on the diameter width of the tree trunk 4' up from the base of the tree. Use 1 cup per caliper inch of tree trunk (diameter), mix with water and evenly apply from the base of the tree to the drip line. Then water into the root zone. You will LOVE the results!

Frequently Asked Questions

What makes Tree Secret® different from other fertilizers for trees?

Most tree fertilizers on the market are either a general lawn fertilizer repackaged with a tree label or a granular fertilizer loaded with synthetic nitrogen that forces fast, weak growth. Tree Secret® was formulated specifically for what trees actually need. The 4-1-0 ratio delivers nitrogen along with sulfur, phosphorus, and available nutrients derived from all-natural sources like alfalfa and rock phosphate. Instead of thinning cell walls with chemical fertilizers, Tree Secret® feeds the microbes in your root zone so they can break down and deliver nutrients at a biological level, supporting stronger root growth, better nutrient availability, and healthy growth that lasts. That's why we consider it the best fertilizer for trees on the market.

Can I use Tree Secret® on shrubs, bushes, and fruit trees?

Absolutely. Tree Secret® works on all types of woody plants, including deciduous trees, evergreens, fruit trees, shrubs, and bushes. Plants and bushes need the same nutrition as slow-growing trees, so a single application of this complete fertilizer gives your entire landscape what it needs. Use it twice per year on stressed or dying trees and once per year for general maintenance. For larger trees, base your dosage on trunk diameter to make sure you're applying enough.

When is the best time to apply fertilizer for trees, and how do I know if my trees need it?

The best time for fertilizer application is in early spring when trees are coming out of dormancy and again in late summer or early fall to help them store nutrients before winter. Avoid fall fertilization too late in the season, as it can stimulate new growth that won't harden off before frost. For established trees, one to two applications per growing season is typically enough. If you're unsure whether your trees need additional fertilizer, a soil test is the best place to start. Your soil test results will show your soil pH and nutrient levels, so you know where the gaps are. Signs of nutrient deficiency include pale or yellowing leaves, stunted new growth, and a thin canopy. Tree Secret® is an excellent foundation for any tree care program because it delivers essential nutrients without the salt buildup that comes with synthetic options.
