Historical Society 's Dedication Tree in need of help.

"Dr. Jimz, I purchased some of your "tree revitalizer" because there is ONE ( of 4) large Caliper crepe myrtles planted and dedicated to individual's loved ones as well as our veterans at our town's local Historical Society grounds that looks like one of your advertised trees "before" & "after" photos. THIS particular crepe myrtle right side is pretty much dead while the left side still flurishes. Since THIS tree is special to me, I decided to give your tree revitalizer a try! ( see pics attached) I'm asking for advice on the best manner in which to distribute your product for optimal results in bringing this special tree back to life. Your response will be greatly appreciated! GYDBD@yahoo.co G. G. Yarborough Bladenboro Historical Society Bd. Mbr."

Awesome product

"Tree secret is the best fertilizer I’ve ever used! It works well and super fast! Chicken soup for the soil is just as amazing. I love all the products I’ve received. I’m a customer for life!"

— Amy H. (5/5)

easy application with hose end sprayer

"I've tried quite a few liquid fertilizers and this was by far the easiest to apply with a hose end sprayer. Wi th the others I have to strain them before using them and this product just sprayed like a dream. Even though it is late October everything is still growing here in Dallas. I still have another month and a half before "fall" aarrives. So 5 stars for ease of application. Too soon to see results in the foliage."

Excellent For Trees

"Have previously used the Tree Secret on a few really old huge hackberry trees and they're doing fantastic and decided to use on three new trees we had planted to help give them a good start. Also used on a wegalia bush and lilacs that weren't looking good and they were absolutely tremendous the last 2 years. Also have used and love the Chicken Soup on flowers and in the garden - another stellar product that helps all the plants look and grow their absolute best. Will also continue to buy both products."

Tree fertilizer

"I used the tree fertilizer a few years ago. My oak keeps dropping leaves and branches. I am hoping that the fertilizer helps keep the tree healthy again. I just put the fertilizer in the ground a month ago. I hope to see some improvement in the spring of 2027."

— Kevin F. (4/5)

Best stuff ever

"I swear by this fertilizer I seen max growth in my boxwoods and my emerald greens went from borderline dead to green and starting to grow I wish there was a rating for 10 stars"

— Kurt m. (5/5)

Saved the Ginkgo

"Several trees bought and planted three years ago. Two are growing excellently and one was struggling. Local extension agent asked for a soil sample. When digging for samples, I found that the root ball had not been properly backfilled with soil and therefore the tree was starving. I backfilled with sand so the roots had something to push against as they tried to get nutrients. I then started using Dr Jimz Tree Secret . I couldn’t see any immediate difference but because there were few roots I didn’t expect much. It’s now Nov26 and the ginkgo has not turned yellow or lost leaves like last year! I’ll be certain come spring 2027, but I’m pretty sure that this ginkgo has been saved. It’s got some catching up to do, and I’m sure that the new supply of Tree Secret will guarantee progress! $35 of Tree Secret beats $750 of dig / replace the existing tree."

3rd year for Arborvitae and paper birches and a redbud.

"Used product early in summer on recommendation of a neighbor with a green thumb. All of these nursery plants were very healthy all summer. Just treated everything now in October and will monitor for continued growth."

— Linda W. (5/5)

1st time

"I was referred to Dr Z's by a family member who stated it saved their 100 yr old pin oak tree. I have a similar walnut tree and would like to save it so I am hoping this helps it. I will know next spring if it is happy again."

— Thomas L. (5/5)

What a difference Dr. Jim’s makes on languishing p

"A few years ago, I first used chicken Soup for the soil in our greenhouse in late summer, when our veggies were languishing from heat and plain well water drenching. The nutrient boost it gave was amazing! New tomato formation, cucumber more plentiful, greens thickening convinced me there was something to his products. We applied Tree Secrets to our newly planted ligustrums that were turning brown. Within a week they made a turn-around and new green foliage appeared. We planted Green Giant arborvitae and I believe it contributed to their initial growth spurt. In a couple years they have tripled in size, however one of them is under stress. We are now actively feeding this tree health dosages and are monitoring its recovery. I have all the confidence it will indeed thrive again. Thanks Doc!!"

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 use synthetic nitrogen that forces fast growth while weakening the tree. Instead of thinning cell walls with chemical fertilizers, Tree Secret® 4-1-2 feeds the soil microbes so they can break down and deliver nutrients at a biological level, supporting stronger root growth and enhanced nutrient availability. This promotes a healthier tree with fewer problems.

There is an array of essential amino acids, multiple sources of minerals, trace minerals, and micro trace minerals all in natural chelated forms. We have an array of organic acids from mineral extracts and have multiple sources of carbon. There is an assortment of sea plant extracts and some compounds found in sea fog that come from the respiration of sea plants, as well as other important plant components. All ingredients are transformed into a colloidal nutrient that is non-leaching and easy for microbes to consume, digest, and feed the plants at a biological level. You won't find a more complete solution; 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, making this complete fertilizer the perfect choice for your entire landscape. 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?

If you have not fertilized your trees yet this year, right now is always the best time to start improving your soil. Tree Secret can be applied anytime; however, it is best to apply in the spring and again in the fall to help trees store nutrients before winter. For established trees, one to two applications per growing season is typically enough. Signs of nutrient deficiency include pale or yellowing leaves, brown needles, 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 and problems that come with synthetic options. We offer a full satisfaction guarantee & hope you give it a Try!
