Best Tree and Shrub Fertilizer

We’ve tested many tree fertilizers, and Jobe’s spikes stand out for their simplicity. Just hammer them into the ground around your trees twice a year. The 16-4-4 NPK formula feeds plants steadily for months.

In our tests, trees and shrubs perked up within days of using these spikes. Leaves looked greener and growth seemed more robust. We liked that there was no need to mix or spread anything – just push the spikes into the soil and you’re done.

One downside is that these are only for acid-loving plants like oak, maple, and dogwood. If you have other types of trees, you’ll need a different product. The 15-count pack also doesn’t cover many trees, so you may need to buy multiple boxes for a larger yard. Still, for easy care of common trees and shrubs, we think these spikes are hard to beat.

We’ve been using BioAdvanced Tree & Shrub Care for a while now, and it’s been a game-changer for our garden. The granules are super easy to apply – no mixing or spraying needed. We just sprinkle them around the base of our trees and shrubs, and we’re done.

One thing we really like is how it tackles two jobs at once. It kills pesky insects like Japanese beetles and aphids, while also feeding the plants. This saves us time and money compared to buying separate products. The slow-release fertilizer gives our plants a steady supply of nutrients, which has helped them look healthier and grow stronger.

The long-lasting protection is a big plus. We only need to apply it once a year, which is great for those of us with busy schedules. It’s absorbed by the roots, so rain won’t wash it away. We’ve noticed fewer pest problems since we started using it, and our trees and shrubs seem more resistant to new infestations.

We’ve been using these Miracle-Gro spikes on our trees and shrubs for a while now, and we’re impressed with the results. The spikes are simple to use – just push them into the soil around your plants. They slowly release nutrients right to the roots, which is great for promoting healthy growth.

One thing we really like is that we only need to apply them twice a year, in spring and fall. This saves us time and effort compared to other fertilizers that need more frequent application. We’ve noticed our plants looking greener and fuller since we started using these spikes.

It’s important to make a starter hole before inserting the spikes, though. We learned this the hard way when a few broke as we tried to push them into hard soil. Also, while the pack covers several plants, you might need to buy more for a larger garden. Despite these minor issues, we think these spikes are a solid choice for keeping trees and shrubs healthy and thriving.

We tried Scotts Tree & Shrub Food on our garden’s evergreens and flowering plants. The powder form was simple to sprinkle around the base of each plant. We liked that we didn’t need to mix it with water or use any special tools.

After a few weeks, we noticed our dogwoods and hydrangeas perking up. The leaves looked greener and the new growth seemed stronger. Our rhododendrons also bloomed more vibrantly than in past seasons.

We appreciated that this fertilizer lasted about two months before needing to reapply. It saved us time compared to liquid fertilizers that need more frequent use. The 3-pound bag covered a good number of our plants, though larger gardens might need multiple bags.

We’ve tried many shrub care products, but BioAdvanced Shrub Shield stands out. It’s a triple-threat, tackling insects, diseases, and fertilization in one go. We spread the granules around our roses and boxwoods, and the results were clear within weeks.

The systemic protection is a game-changer. It travels through the entire plant, safeguarding new growth too. We noticed fewer aphids and a marked decrease in black spot on our roses. The fertilizer boost was evident in the richer green color and stronger stems of our shrubs.

One thing we love is how simple it is to use. Just sprinkle the granules and you’re done – no mixing or spraying needed. It’s a bit pricey, but we think the convenience and effectiveness make it worth it. For busy gardeners or those with lots of shrubs, this product is a real time-saver.

We tested this TPS NUTRIENTS fertilizer on a row of struggling arborvitae trees. The liquid form made it simple to mix and apply. Within two weeks, we saw fresh growth and greener foliage.

Our blue spruce in a container perked up too. It sprouted new shoots after just a few applications. The 32-ounce bottle lasted longer than we expected, covering several trees and shrubs.

A few of our team members noticed packaging problems. One bottle arrived without a cap. While this didn’t affect the product inside, it made storage tricky. We solved this by transferring it to another container. Despite this hiccup, we think the results are worth it for most gardeners dealing with lackluster evergreens.

We tried the BioAdvanced Tree & Shrub Protector on our Japanese magnolia and were impressed with its ease of use. The concentrate formula mixes easily with water, and we simply poured it around the base of the tree. No messy spraying was needed.

One thing we really liked was how it tackles multiple issues at once. It killed existing pests like scale insects and prevented new ones from moving in. At the same time, it fed our tree with a slow-release fertilizer. This two-in-one approach saved us time and effort.

The long-lasting protection is a big plus. We only needed to apply it once, and it kept working for a full year. This made it a set-and-forget solution for our busy schedules. We did notice it took a few weeks to see results, but once it kicked in, our trees looked healthier and pest-free.

We tried this TPS NUTRIENTS liquid fertilizer on several trees and shrubs in our test garden. The 32-ounce bottle was simple to use. We mixed it with water as directed and applied it to the soil around our plants.

Our young trees showed new growth within a week of the first use. The leaves looked greener and healthier. We noticed this effect on both our oak saplings and cypress trees.

We also tested it on some boxwoods. These shrubs responded well, developing a deep green color that made them stand out. The product seemed to work on different plant types, which we liked.

One thing we found tricky was figuring out how much to use per tree. The instructions weren’t very clear on this point. We worried about using too little or too much. It might take some trial and error to get the dosage right for your plants.

The liquid form made it easy to apply with a hose sprayer or by mixing in a jug and pouring. This was less messy than dealing with granular fertilizers. But we did need to reapply it often, about once a week for best results.

While the 32-ounce bottle is a good size for trying out the product, it might not last long if you have many trees or large shrubs to feed. You may need to buy multiple bottles for bigger gardens or yards.

We tested Bloom City’s Tree & Shrub Fertilizer on a mix of plants in our yard, and we were pretty happy with the results. Our magnolias perked up nicely, and we saw a good boost in growth for our other trees and shrubs too.

The liquid form makes it simple to use. We just mixed it with water and applied it to the soil around our plants. It’s nice that one product works for both trees and shrubs – it saved us from buying separate fertilizers.

We did notice that some plants needed more frequent applications to keep up the growth. While most of our greenery thrived, a few didn’t show as much improvement as we hoped. It’s worth noting that results can differ based on your soil type and plant health.

We tried out these Old Farmer’s Almanac Tree & Shrub Fertilizer Spikes in our garden, and we were pretty impressed. The spikes went into the ground smoothly, even in our clay-heavy soil. We didn’t need a special cap or tool – just a regular hammer did the trick.

The 13-3-3 formula gave our plants a nice boost. We noticed greener leaves and more growth on our young maple tree within a few weeks. The slow-release nutrients meant we didn’t have to fertilize as often, which was a big plus for us busy gardeners.

We liked that these spikes use natural ingredients like molasses. It made us feel good about what we were putting into our soil. The box says to use them in spring and fall, but we found one application in spring was enough for our smaller trees and shrubs.
