Review: Great product - I've used Jobe's for years and they work great. When we moved into our house 20 years ago a neighbor and I used Jobe's on all the trees along our block.

Nitrogen, potassium, etc?** A: Nitrogen, phosphate, potash, 16-4-4 **Q: I have a small Japanese Maple and 10 young tea olives that I want to use the spikes to fertilize. How many per tree would be enough trough spring and** A: It depends on the diameter (i.e., trunk width at 1 ft from grade) of the trees. If 1-2 inches, then plan on 2 spikes per tree. Above 2 inches, its basically 1 spike per inch diameter. **Q: We have a 25 year old (40ft) maple tree in tx that doesnt look healthy. Will this product work? How should we use it? Thank you** A: Your maple needs iron like someone else posted. So no, this product is not enough because you need the IRON! Try this product from Jobes: Ross® Green Again Iron Formula Root Feeder Refills Make sure your trees are healthy and green all season long with Ross® Root Feeder Refills Green Again® with Iron. Chlorosis, a yellowing of the leaves with green veins, is caused by a lack of iron in your plant’s diet. Use refills in your Ross® Root Feeder to get the perfect balance of nutrients directly to plants’ roots - while watering. These refills are a special formula of fertilizer plus iron for plants suffering from yellow-leaf iron deficiency. Apply when first symptoms appear or to prevent deficiency if chlorosis has been a problem previously. Ross® pre-measured refills make for fast, easy and mess-free fertilizing. **Q: is this Spike for Dogwood Trees?** A: I do not know about dogwood trees. I have used this spike on my Hickory tree, Ash tree, Maple tree and Spruce tree. They have all done well. Grew larger with many leaves. I am not a 'gardener' but person who uses fertilizer on my lawn, shrubs, flowers and trees. Dogwood is a deciduous tree and I would think that these spikes would not harm it -- as I have used it with my deciduous trees. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by D***S on May 24, 2026* I've used Jobe's for years and they work great. When we moved into our house 20 years ago a neighbor and I used Jobe's on all the trees along our block. The untreated trees across the street are definitely smaller in both height and circumference. Our trees all seem healthier too ### ⭐⭐⭐⭐⭐ These must have a magic potion! *by K***. on July 8, 2026* Gives my shrubs and trees a growth injection that makes them healthy! ### ⭐⭐⭐⭐ WOW! What an AMAZING DIFFERENCE = WORKS!! *by E***H on May 13, 2026* After YEARS!, I mean YEARS of what I learned last year was ‘Scale’ growing on my mum’s Japanese Magnolia Trees (2) (see the pic = YUCK!) I did some research, and learned about this product. Initially, I tried to treat the plant using just diluted Neem Oil spray. Unfortunately, the treatment did more damage than good (when treating w/Neem oil it really has to be diluted or it will burn the plant’s leaves, etc..).. Apparently, all I needed to do was get this stuff, Shake out a bit and scatter it around the base of the trees. The way this product works, is that the product sits at the base of the plant, and when watered, the product then soaks into the ground and the plant then uptakes the product into its system, and when the pests (scale, gnats, aphids, etc..), attack the plant, they basically get a mouth full of YUCK!🤮 and either die or go away. DO NOT USE WHEN RAINING! as the product will not soak into the ground and treat that specific plant, but instead, it will go where ever the water goes and potentially contaminate your garden and any edible plants growing nearby, and you DO NOT want to EAT anything treated by this product! I figured “Meh, Why Not?!” I’ll give it a try at least, at approx. $23USD, it was well worth it to try. Around February, I had my mum (82yo) treat the trees, which consisted of just shaking out the designated amount of product and tossing It around underneath both trees. I stated her age to emphasize that anyone can use this product, it’s that easy to use. By March, both of her Japanese Magnolia trees put out blooms like they had not in YEARS! I mean they were GORGEOUS! We had neighbors comment on how beautiful the trees were. All that, compared to previous years, where both trees were sickly, covered in leaves, but few if any blooms, and almost every joint in the trees had these yellow black ‘lumps’. I now know the ‘lumps’ were ‘scale’, and the black stuff was likely black soot/fungus. We live with some tall trees behind us/on our east side and the trees although located further out in the yard, probably both were infected by the black soot being in the air/drifting on the wind and landing on the trees. But, after this treatment, all GONE! *smiles*😁👍🏼 I HIGHLY RECOMMEND You try this product on ANY “NON-Edible” plant. Do NOT use on ANYTHING You plan to EAT! Because, this product works by your plant up-taking it into the plant itself and distributing it throughout the plant’s roots, stems, leaves, blooms/fruit, etc... Also, You only need to make sure to use this product far enough in advance of Spring/Summer that the plant has time enough to up-take it and distribute it internally. BEST OF ALL, You only need to use this product ONCE every YEAR!! (12mths!) ••••> PRO’s: •••••• • EASY USE - Just Shake it out and distribute it under the plant at the base. • PESTS / Lots! = This product treats a WIDE VARIETY of plant pests and disease(s). • QUANTITY / Lasts! = Depending upon the area/plants you wish to treat, it really only takes a little bit of product. Plus, as You only need to apply the product ONCE YEARLY, a little bit goes a long way, and the container size should last you a long time. • ANNUALLY = You only need to apply this product ONCE YEARLY! • COST = The approx $23 cost is minimal when you consider the quantity you get, along with the amount of product needed to treat a plant, considering all of that, the price is cheap! ••••> CON’s: ••••• • TOXIC = This product is toxic enough that it should NOT be used on ANY plant that produces Edible Produce/Fruit. Because the plant up-takes the product into ALL parts of the plant, the stem, leaves, blooms/fruit, so that anything edible will be full of this toxic product, not edible and toxic if eaten. • CONTAMINATION = MUST be applied to plant at base on a dry day, because otherwise, the product will spread to where ever the water it sits in travels and can potentially contaminate other plants that produce edible fruit/produce, making it in edible or if eaten, potentially poison whomever eats it. • TIMING = Must be applied early enough before Spring/Summer that the plant has time to up-take the product into itself internally and distribute it through out itself. ••••> OVERALL OPINION: ••••• Overall I feel this is a GREAT product to use and try, it worked WONDERS to completely cure two very over run and sickly Japanese Magnolia Trees, which are now producing Gorgeous Blooms! And, I no longer feel bad/guilty, because the trees look so bad/sickly (& I don’t have to worry about the scale spreading to our other plants!!) Unfortunately, I do not have any of the pics from the trees blooming this year, because I waited too long and there has been so much rain, BUT, I’ll try to update with pics next time they bloom, to show you just how gorgeous the tree and blooms are now, all cured, green lush and entirely covered in beautiful purple flowers!😁👍🏼 ## Frequently Bought Together - Jobe’s Slow Release Tree and Shrub Fertilizer Spikes, Easy Plant Care for Oak, Maple, Dogwood, Boxwood, and Many More Acid Loving Trees and Shrubs, 15 Count - Miracle-Gro Tree and Shrub Plant Food Spikes, For Deciduous, Flowering and Evergreen Trees, 12 Spikes --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ma/products/1180985-jobe-s-slow-release-tree-and-shrub-fertilizer-spikes-easy](https://www.desertcart.ma/products/1180985-jobe-s-slow-release-tree-and-shrub-fertilizer-spikes-easy) --- *Product available on Desertcart Morocco* *Store origin: MA* *Last updated: 2026-08-13*
