Best Food Spikes For Trees for Fruit, Shade, and Evergreens

#1 · Best Overall

1. Miracle-Gro Fruit & Citrus

• Weight: 3.8 lb
• Form: Sticks

Best for: Fruit-tree and citrus growers.

Why it ranks #1: Made for fruit and citrus trees including apple, orange, lemon, lime, and avocado; its directions place spikes around the drip line.

A formula specifically named for fruit and citrus trees gives this Miracle-Gro spike a focused role in feeding apple, orange, lemon, lime, and avocado trees. The listing also includes palms, so it suits growers tending several of those plants who want a solid-form feeding option rather than a general-purpose liquid.

The label directs you to soften the soil by watering first, then place spikes around the plant’s drip line at least three feet apart. That sequence connects the stick format to a defined in-ground routine, while the label’s chart guides how many spikes to use. Driving each spike fully below the soil surface leaves it positioned around the root-zone perimeter. The stated fruit-and-citrus formulation and fruit-production purpose make this a targeted pick rather than an all-tree formula.

Skip it if you need a complete feeding schedule from the listing; consider Jobe’s Tree Fertilizer Spikes, which specify early spring and late fall application.

Fruit-tree growers with citrus, avocado, or palms can use the crop-specific formula and drip-line instructions to guide placement. Choose another option if a complete application calendar is essential; this listing leaves its schedule unfinished.

#2 · Best General Formula

2. SimplyGro Tree & Shrub 8-8-8

• Weight: 3 lb
• Form: Sticks

Best for: Mixed tree and shrub gardens.

Why it ranks #2: Its 8-8-8 formula is listed for deciduous, coniferous, decorative, flowering, and fruiting trees and shrubs, making it a broad-use choice.

An 8-8-8 formula gives this SimplyGro spike equal listed percentages of nitrogen, phosphorus, and potassium, supporting a broad range of trees and shrubs. Its stated scope includes deciduous, coniferous, decorative, flowering, and fruiting plants, making it especially relevant to mixed gardens.

Each spike measures five inches, and the product describes its use as a set-it-and-forget-it solution. Those features pair a defined stick size with a low-frequency-care positioning for gardeners tending different plant types. The 8-8-8 formula is described as providing nitrogen for growth and color, phosphorus for fruiting and flowering, and potassium for strong roots. Together, the broad plant list and balanced ratio make it a general garden option rather than a crop-specific feed.

Skip it if you need detailed placement directions and a spring-and-fall schedule; Jobe’s 16-4-4 Tree Fertilizer Spikes provide both.

Mixed-garden owners seeking one stated formula across deciduous, coniferous, flowering, and fruiting plants may value this broad scope. Look elsewhere if you need explicit timing and placement directions before applying fertilizer.

#3 · All-Season Feeding

3. Jobe's Tree Fertilizer 16-4-4

• Weight: 8.3 lb
• Form: Sticks

Best for: All-season deciduous tree care.

Why it ranks #3: This 16-4-4 formula is for deciduous trees and shrubs, with 15 spikes per package and directions for early spring and late fall.

A 16-4-4 time-release formula supplies this Jobe’s spike with a defined nutrient ratio for deciduous trees and shrubs. Its below-surface delivery targets the area where active roots grow, making the format relevant to gardeners seeking a seasonal feeding routine without mixing or measuring fertilizer.

The product is intended for all deciduous trees and shrubs, and its directions place spikes around each tree’s drip line in early spring and late fall. That placement pairs the time-release approach with a twice-yearly schedule, while the pre-measured stick form removes mixing and measuring from the task. Jobe’s also says the spikes feed all season and will not burn trees. Buyers should still follow the product’s drip-line directions for placement.

Skip it if you mainly feed evergreens; Jobes 01611 Evergreen Tree Fertilizer Spikes are specifically labeled for evergreen trees and shrubs.

This is a fit for gardeners feeding deciduous trees or shrubs who want pre-measured spikes and a spring-and-fall schedule. Its stated plant scope is deciduous, so evergreen owners should choose an evergreen-labeled formula.

#4 · Fruit Nutrient Blend

4. Power Spike Fruit Tree

• Weight: 3.2 lb
• Form: Sticks

Best for: Fruit trees with nutrient needs.

Why it ranks #4: Designed for fruit trees, it combines NPK nutrients with magnesium, manganese, iron, zinc, copper, and sulfur in a 10-spike, 3.2-pound package.

A combination fertilizer and nutrient spike formulated for fruit trees makes Power Spike a targeted option for growers concerned with common deficiencies. Its listed plant examples include apple, peach, orange, lemon, and lime, while the nutrient blend includes several trace elements alongside the primary nutrients.

The ingredients list nitrogen, phosphate, and potash as well as magnesium, manganese, iron, zinc, copper, and sulfur. That breadth connects the product’s deficiency-focused positioning to a named mix of nutrients, while its root-zone delivery aims to feed feeder roots. The listing says the spikes help enhance fruit development and includes a pounding cap, linking the solid format to installation without requiring buyers to source that listed accessory separately.

Skip it if you need a defined spring-and-fall feeding calendar; Jobe’s 16-4-4 Tree Fertilizer Spikes list those application times and drip-line placement.

Fruit-tree growers seeking a nutrient blend that names several trace elements may find this focused option relevant. The listing gives no timing or spacing directions, so it is less suitable when a detailed application routine is essential.

Listed on Amazon as: for Fruit Trees. Essential Nutrient Spike formulated to Feed All Types of Fruit Trees (Apple, Peach, Orange, Lemon, Lime, etc.) and Address Common Deficiencies (10 Spikes – 3.2 Lbs)

#5

5. Jobe's Slow Release 15-3-3

• Weight: 1.2 lb
• Form: Sticks

Best for: Acid-loving tree and shrub care.

Why it ranks #5: Its 15-3-3 formula targets acid-loving trees and shrubs, with five pre-measured spikes and twice-yearly application directions.

A 15-3-3 formula and explicit focus on acid-loving trees and shrubs set these Jobe’s spikes apart from general tree feeds. The listing names oak, maple, dogwood, and boxwood, giving gardeners examples of the intended plants while targeting nutrient delivery below the soil surface.

Jobe’s describes continuous nutrient supply below ground, where active roots grow, and recommends applying spikes twice yearly in early spring and late fall. The directions call for a hammer and plastic spike cap, with spikes driven one to two inches below the surface and evenly spaced. These details make the task specific and repeatable, though they also mean the routine requires the cap and a hammer. The five-count package suits a smaller number of placements.

Skip it if you want hammer-in spikes without a plastic cap; The Old Farmer’s Almanac Evergreen 10-4-10 TruSpike says no cap or special equipment is needed.

Choose these for acid-loving trees and shrubs when the listed 15-3-3 formula and spring-and-fall schedule fit your routine. Account for the specified hammer-and-cap installation before choosing them for your garden.

#6 · Largest Pack

6. Winchester Gardens Landscaper Pack

• Weight: 18 lb
• Form: Sticks

Best for: Large-scale tree feeding.

Why it ranks #6: The 15-10-9 formula comes in a 70-spike case, a useful format for feeding many trees or shrubs rather than a few plants.

A 70-spike case gives Winchester Gardens’ 15-10-9 tree and shrub fertilizer a larger supply format for tending multiple plants. The listing pairs pre-measured dosage with no-mess, no-runoff use, so the spikes suit yard care where repeatable placement matters more than mixing fertilizer for each application.

The stated 15-10-9 formula provides a defined nutrient ratio, while the pre-measured dosage is described as reducing waste. Directions call for placing spikes evenly around the base of each tree or shrub and allowing them to dissolve over time. That routine avoids mixing and is presented as a continuous-nourishment approach. The product also claims child- and pet-friendly use; buyers should still follow its label directions when placing fertilizer around the yard.

Skip it if you need a stated spring-and-fall schedule for deciduous trees; Jobe’s 16-4-4 Tree Fertilizer Spikes specify those application times.

Gardeners treating many trees or shrubs may appreciate the case quantity and pre-measured format. The listing does not identify specific plant categories or timing, so choose another product when those details guide your feeding plan.

#7

7. Old Farmer's Almanac Natural Spikes

• Weight: 1.5 lb
• Form: Sticks

Best for: Natural-ingredient tree feeding.

Why it ranks #7: This tree and shrub product includes six spikes and lists ingredients including corn gluten meal, urea, muriate of potash, and ammonium phosphate.

Corn gluten meal is among the listed ingredients in these Old Farmer’s Almanac TruSpikes, giving buyers a named component to consider when choosing tree and shrub fertilizer. The six-spike, stick-form package fits a straightforward in-ground routine, with directions calling for applications in early spring and late fall.

The ingredients also include urea, muriate of potash, and ammonium phosphate, so the product identifies several components of its fertilizer blend rather than presenting an unspecified formula. Directions say to water well before application and drive each spike into the soil with a hammer. Paired with the two-season schedule, that makes the routine easy to plan around seasonal yard care. The title names both trees and shrubs, making it a broad category option rather than a fruit-specific feed.

Skip it if you need a stated NPK ratio; The Old Farmer’s Almanac Evergreen 10-4-10 TruSpike lists one for evergreen feeding.

Choose these TruSpikes if you want a tree-and-shrub option with named ingredients and a spring-and-fall routine. The listing does not state an NPK ratio, so shoppers comparing nutrient analyses should look elsewhere.

#8

8. Old Farmer's Almanac Evergreen 10-4-10

• Weight: 3 lb
• Form: Sticks

Best for: Evergreen and fir tree care.

Why it ranks #8: Its 10-4-10 formula is specifically intended for evergreen, fir, and conifer trees and shrubs, so it suits those plantings better than mixed use.

A 10-4-10 formula explicitly aimed at evergreen and fir trees gives this Old Farmer’s Almanac TruSpike a defined plant scope and nutrient ratio. Its hammer-in design needs no plastic cap or special equipment, simplifying installation for buyers who want a dedicated evergreen spike.

The product describes its patented TruSpike as resistant to breaking, crushing, or smashing, and says it can be driven in with a hammer alone. That installation approach removes the need for a separate cap, while the pre-measured 10-4-10 formula provides a named nutrient balance. The listing covers evergreen and fir trees, as well as shrubs and conifers in its description, making it a targeted option for those plant groups rather than fruit-tree feeding.

Skip it if you need explicit drip-line spacing and spring-and-fall timing; Jobes 01611 Evergreen Tree Fertilizer Spikes provide those directions.

Evergreen, fir, and conifer owners seeking a stated 10-4-10 formula and cap-free hammer installation may find this a suitable fit. Look elsewhere if you need application timing and placement spacing spelled out.

#9

9. Jobes Evergreen 13-3-4

• Form: Sticks

Best for: Evergreen and conifer feeding.

Why it ranks #9: The 13-3-4 formula is directed at evergreen trees and shrubs, with twice-yearly application guidance; the listing also notes a Florida shipping restriction.

A 13-3-4 NPK blend and explicit evergreen labeling give these Jobes spikes a focused role for evergreen trees and shrubs. The product describes slow-release feeding below the surface to target active roots, making it suited to growers seeking a dedicated alternative to general tree fertilizer.

Directions call for inserting the spikes around the drip line and applying them twice a year in early spring and late fall. That placement and schedule provide a defined routine, while the stated continuous supply of nutrients below the surface connects the slow-release formula to root-zone feeding. The listing says the spikes minimize runoff, mess, and odors. One important boundary is geographic: the product information says it cannot be sold or shipped into Florida.

Skip it if you live in Florida; The Old Farmer’s Almanac Evergreen 10-4-10 TruSpike is another listed evergreen-specific option.

Evergreen owners who want a stated nutrient ratio and twice-yearly drip-line directions can consider these spikes outside Florida. The listed shipping restriction makes them unsuitable for buyers in that state.

#10

10. JOBE'S Tree Fertilizer Spikes

• Weight: 2.5 lb
• Form: Sticks

Best for: Basic tree-spike listing.

Why it ranks #10: The title identifies tree fertilizer spikes, but the supplied listing gives no formula, package count, tree-type guidance, or application directions.

The title identifies this as Jobe’s tree fertilizer spikes, with a 2.5-pound item weight and stick form stated in the specifications. Those are the concrete details available here, so this listing is best considered by shoppers who need the product identity and format rather than a documented nutrient profile.

The supplied specifications identify the brand as Jobes, the item form as sticks, and the weight as 2.5 pounds. The listing does not provide a fertilizer ratio, plant categories, or application directions in the supplied product information, limiting how precisely buyers can match it to a tree or feeding schedule. Its title establishes a tree-fertilizer purpose, but shoppers who need timing or nutrient details should use a listing that states them.

Skip it if you need an NPK ratio and a stated feeding schedule; Jobe’s 16-4-4 Tree Fertilizer Spikes provide both nutrient and timing details.

This listing may suit buyers who recognize the Jobes tree-spike product and need its stated stick form and weight. Choose a more detailed listing if plant scope, nutrient ratio, or application timing will guide use.
