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 ### ⭐⭐⭐⭐⭐ Review *by R***G on 26 April 2024* Excellent ### ⭐⭐⭐⭐⭐ Review *by A***H on 8 October 2015* Arrived safe ### ⭐⭐⭐⭐⭐ Review *by R***M on 2 December 2025* We had a small tree that was hurting. The arborist recommended we use these spikes twice a year and water in good. The tree has really bounced back and looks great. ## 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.vu/products/254385071-jobes-01660-1610-0-tree-fertilizer-spikes-16-4-4](https://www.desertcart.vu/products/254385071-jobes-01660-1610-0-tree-fertilizer-spikes-16-4-4) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-04*
