Fruit & Citrus Plant Food Spikes

I’ve been using the Miracle-Gro Fruit & Citrus Plant Food Spikes for several seasons now, and they continue to be one of the easiest and most effective ways to fertilize my citrus trees. I have a few dwarf citrus varieties—lemon, lime, and a young satsuma—and these spikes have made a noticeable difference in growth, foliage health, and fruit production. What I really love about this product is the convenience. Instead of mixing liquid fertilizers or trying to spread granular feed evenly, you just push these spikes into the soil near the root zone (according to the package instructions), and you're done. The nutrients are slowly released over time, so the trees get consistent feeding without risk of over-fertilizing. I apply them about once in early spring and again mid-summer, and that seems to be enough for my potted and in-ground trees. Within a few weeks of using the spikes, I typically see deeper green leaves and more vigorous new growth. One of my potted Meyer lemons that had been looking pale really perked up after I added the spikes—leaves darkened and the tree produced a healthy flush of blooms. I also appreciate that Miracle-Gro tailored this formula specifically for fruit and citrus, as not all plant food is created equal. This gives me some peace of mind that I'm giving my trees what they need without guessing. Highly recommend for both new and experienced gardeners who want a low-maintenance, effective way to support healthy citrus and fruiting plants!

The product listing does not tell you but the Miracle-Gro spikes are 15-5-10 I live in northern Nevada and have a couple Austrian pines that are 10’ plus. They were dying, no matter how much water I gave them they were losing their Needles, the branches were drying out and breaking. I used these fertilizer spikes and they came back to life turned a brighter green, and actuality had a noticeable amount of growth. Spikes are not very big and pound into the soil easily.

1st time I have used the Miracle Grow branded tree spikes as I mostly use another brand, but these were on sale so I got a couple boxes. some of the spikes had cracks and broke while planting them even with the ground being softened. not all of them were like that, but I had to use a shovel to get the fertilizer in the ground when they broke. Past brands I never had that problem. I se a rubber mallet to drive them down into the soil and never had a problem. May have been a bad box or handled rough. I cannot say how good the results will be, but I am confident they will work great Miracle Grow makes great fertilizer that works very well. If I notice a real difference I will update this at a later time. 4 star was because the spikes having cracks in them they need to package them better to keep this from happening.

I used these fertilizer spikes on a few fruit trees that were looking like they were struggling. I waited until the ground was soft, which made it much easier to get them in. I placed the spikes just outside the drip line. They did break apart a bit while going in, but that didn’t affect how they worked. (And yes—the video shows my son pounding one in, but that was after we tried pushing it in by hand!) Overall, they were easy enough to use and seem to be helping the trees perk up.

I purchased this product since I have used it before on my Lemon Tree. Works great and I like the longevity.

I’ve been using the Miracle-Gro Fruit & Citrus Plant Food Spikes for my small backyard orchard, including orange, lemon, and grapefruit trees, and I’m thrilled with the results! These spikes are incredibly easy to use—just push them into the soil near the roots, and they take care of the rest. The time-release formula delivers steady nutrients, which has led to noticeably healthier trees. Within a few weeks of applying the spikes in early spring, I saw vibrant green leaves, stronger branches, and a significant increase in blooms. My lemon tree, which struggled last season, produced a bumper crop of juicy fruit this year. The convenience of not having to mix or measure fertilizers makes this a go-to for busy gardeners like me. I also appreciate the tailored formula for citrus and fruit trees, ensuring they get exactly what they need. Whether you’re a novice or seasoned gardener, these spikes are a game-changer for healthy, productive trees. Highly recommend and will definitely purchase again!

I picked up 3 fruit tree saplings around 3' tall that someone had put out by the curb and planted them way in the back of the property. The apple had looked most promising but has been the slowest grower with very few leaves over the past 3 years. But I never put these in as they should have been and the soil is rocky. The other two are peach trees and the main part of both died and are surviving with suckers off the roots. One is near useless and off the edge and might not survive. The other with two suckers has one that is straight up and tied to a pole and doing well this year. Even though it's a little late for the spikes, it's better than never. They don't get full sun and I didn't want to have to water them as much anyway with the rocky soil. I had to put up wire around these saplings to keep the deer from chewing on them, which is what happened to the apple tree. The wire is only 4' and the peach is already past the top. Insects are another issue, I would have liked these spikes to help with. I have some dry spread for the insects, but isn't meant for young trees. 3 spikes were broken but I used a small shovel anyway as the spikes would have broken in the rocky soil. Being what they are and looking back, I should have done my homework as I might have had much larger and healthier trees by now.

Every spring I use these and so far my shrubs have stayed very healthy
