#1 · Best Overall

1. Espoma Tree-Tone

• Weight: 36 lb
• Form: Granules

Best for: Large-Tree Organic Feeding.

Why it ranks #1: Its 6-3-2 analysis and 5% calcium suit shade, fruit, and ornamental trees, and the 36-pound granular bag is ready to use without mixing.

A 36-pound bag of Espoma Tree-Tone supplies a 6-3-2 blend with 5% calcium, giving gardeners a substantial granular option for shade, fruit, and ornamental trees. Its ready-to-use format means there is no mixing step, and the listed schedule points to spring and fall applications for routine tree care.

Tree-Tone covers shade, fruit, and ornamental trees, with apple and peach trees specifically included, so one fertilizer can serve several tree types in a garden. The 6-3-2 analysis and 5% calcium identify the nutrient profile, while the natural and organic ingredient blend is enhanced with Bio-tone. Granules are ready to use without mixing, which keeps application straightforward. The 36-pound bag suits gardeners tending multiple trees or planning repeated spring and fall feeding; package directions guide safe application.

Skip it if you need a fertilizer specifically formulated for citrus; Espoma Citrus-Tone targets citrus, avocado, and nut trees.

Choose this large-bag option for gardeners feeding several shade, fruit, or ornamental trees with a ready-to-use organic granular fertilizer. Its listed spring and fall timing is a useful planning cue, but the 36-pound quantity suits broader tree-care needs.

#2 · Best Testing Bundle

2. MYGP Tree-Tone Kit

• Weight: 4 lb
• Form: Granules

Best for: Tree-Tone with Garden Tools.

Why it ranks #2: The 6-3-2 Tree-Tone formula targets shade, fruit, and ornamental trees; the bundle also includes soil test strips and gardening claw gloves.

This My Garden Pool bundle pairs 4 pounds of organic Tree-Tone granules in a 6-3-2 ratio with soil-test strips and gardening accessories. The combination gives tree gardeners fertilizer plus listed testing and handling items, while the Tree-Tone formula is aimed at shade, fruit, and ornamental trees.

The bundle centers on Tree-Tone’s 6-3-2 nutrient ratio and describes the granules as enriched with Bio-tone microbes, connecting the fertilizer with nutrient absorption. Its stated tree scope includes shade, fruit, and ornamental varieties. The package also lists 20 pH soil-test strips, gardening claw gloves, and Garden-IQ, adding tools alongside the four-pound fertilizer quantity. Directions mention applying 2 pounds per inch of trunk diameter under the drip line for shade trees, so the supplied amount is a relevant planning consideration.

Skip it if you need a 36-pound Tree-Tone quantity for multiple large trees; the My Garden Pool Espoma Tree-Tone bundle lists that bag size.

This bundle suits gardeners who want Tree-Tone plus soil-test strips and listed accessories in one purchase. The four-pound amount is better matched to limited applications; use the stated trunk-diameter rate when planning shade-tree coverage.

3. MYGP Espoma Tree-Tone Kit

• Weight: 36 lb
• Form: Granules

Best for: Bulk Tree-Tone Bundle.

Why it ranks #3: This 36-pound Tree-Tone bundle targets shade, fruit, and ornamental trees, with soil test strips and gardening claw gloves as useful extras.

A 36-pound bag of Espoma Tree-Tone anchors this My Garden Pool bundle, pairing a large quantity of 6-3-2 organic fertilizer with pH test strips and gardening claw gloves. Its stated scope covers shade, fruit, and ornamental trees, making the bundle relevant to broader tree-care routines.

Tree-Tone’s natural and organic ingredient blend is described as containing beneficial microbes and humates, while the 6-3-2 formula is identified for shade, fruit, and ornamental trees. The 36-pound bag provides substantially more fertilizer than a small-format bundle, which is useful when planning care across multiple trees. Included pH soil-test strips and claw gloves add garden tools to the package. The listing also emphasizes a formula without sludges or fillers; follow the product’s handling directions during application.

Skip it if you only need a smaller Tree-Tone quantity with accessories; the My Garden Pool MYGP TR4 bundle lists 4 pounds.

This bulk bundle fits gardeners managing several shade, fruit, or ornamental trees who can use a 36-pound bag. Its included strips and gloves add practical extras, but the large quantity is a poor fit for limited tree-care needs.

#4 · Best Spike Format

4. Jobe's Tree Spikes

• Form: Sticks

Best for: No-Mixing Tree Spikes.

Why it ranks #4: These organic 5-5-5 time-release spikes are explicitly intended for all shrubs and trees, offering a different format from loose granules.

Jobe’s Organics Tree Fertilizer comes as 5-5-5 time-release spikes for shrubs and trees, offering a solid-format alternative to granular products that must be spread. The package title lists 10 spikes, a count that helps buyers plan applications across their planting rather than measure a liquid dilution.

The title identifies a 5-5-5 analysis and a time-release format, giving buyers both a nutrient ratio and a stated release approach. Spikes are listed for all shrubs and trees, so this option is not restricted to fruit-bearing varieties. The package contains 10 spikes, allowing gardeners to plan around a fixed number of pieces. Unlike a liquid concentrate, the format does not require measuring a water dilution; the supplied information does not specify an application rate or schedule.

Skip it if you need a stated application schedule for fruit trees; Dr. Earth Natural Wonder lists feeding for up to two months.

Choose these spikes if you want a time-release solid fertilizer for trees or shrubs and prefer not to measure a liquid dilution. The package count is clear, but buyers needing a stated application rate or schedule should weigh that limitation.

#5 · Broad-Use Pick

5. Jobe's All Purpose Granules

• Weight: 4 lb
• Form: Granules

Best for: Mixed Garden Tree Feeding.

Why it ranks #5: The 4-pound organic granules are listed for trees as well as vegetables, flowers, and shrubs, and the description notes longer-lasting feeding.

Jobe’s Organics Granular All Purpose Fertilizer covers trees alongside vegetables, flowers, shrubs, and other plants, making it a practical option for mixed gardens. Its fast-acting organic formula is described as increasing microorganism activity in soil, while the granular form avoids the need to dilute a liquid concentrate.

The all-purpose label allows this fertilizer to serve trees and several other garden categories, so one product can fit a varied planting list. Its granular form is ready to apply without a water-dilution step, and the product description says the formula increases microorganism activity for living soils. Jobe’s also describes its organic granules as fast acting. The four-pound bag is a smaller quantity than bulk tree-care bags, while general handling guidance calls for gloves and washing hands after use.

Skip it if you want a tree-specific organic formula with a defined 6-3-2 analysis; Espoma Tree-Tone lists that nutrient ratio.

This is a flexible pick for gardeners feeding trees as part of a broader mix of flowers, vegetables, and shrubs. Its granular format suits those avoiding liquid mixing, but the four-pound bag is a limited quantity for extensive tree plantings.

#6 · Best for Citrus

6. Espoma Citrus-Tone

• Weight: 4 lb
• Form: Granules

Best for: Citrus and Avocado Care.

Why it ranks #6: Its 5-2-6 analysis with 5% calcium targets citrus, avocado, and nut trees, with application guidance for late winter, spring, and fall.

Espoma Citrus-Tone pairs a 5-2-6 analysis with 5% calcium for citrus trees, including lemon, lime, orange, and Meyer lemon, as well as avocado and nut trees. That crop-specific scope helps gardeners choose one granular formula for several fruiting tree types, with applications listed for late winter, spring, and fall.

The product’s stated range includes citrus, avocado, and nut trees, making it a focused choice for gardens with those crops rather than a general tree blend. Its 5-2-6 analysis and 5% calcium provide a defined nutrient profile, while natural and organic ingredients are enhanced with Bio-tone. Granules keep the product in a ready-to-spread form. Directions specify 4 pounds per application, spread evenly over the tree or plant area, and say to repeat as needed for continuous feeding.

Skip it if you need a broad shade-tree fertilizer; Espoma Tree-Tone is listed for shade, fruit, and ornamental trees.

Citrus, avocado, and nut growers who want a granular formula with a stated application rate will find a clear fit here. Its seasonal schedule spans late winter, spring, and fall, while gardeners with mainly shade trees may prefer a broader-purpose option.

#7

7. Dr. Earth Natural Wonder Minis

• Weight: 16 oz
• Form: Granules

Best for: Backyard Fruit and Berries.

Why it ranks #7: This 5-5-2 organic granular blend is intended for fruit trees and berries, feeds for up to two months, and covers 15 square feet.

Dr. Earth Natural Wonder combines a 5-5-2 analysis with a stated feeding duration of up to two months, offering fruit-tree and berry growers a granular option with a defined coverage note. The 100% organic and natural blend is also listed for fruiting vines, containers, and backyard soils.

The product’s listed uses span citrus, apples, peaches, nut trees, berries, avocados, and grapes, so it can cover a varied fruiting garden. Its 5-5-2 analysis identifies the nutrient ratio, and the product description connects the blend with healthy roots and fruit growth. Granules are listed to feed plants for up to two months and cover 15 square feet, giving buyers a useful planning reference. The Trubiotic premium probiotic package is another stated feature of this organic blend.

Skip it if you need fertilizer for shade and ornamental trees as well as fruit trees; Espoma Tree-Tone lists all three categories.

This granular blend suits backyard growers feeding fruit trees, berries, or fruiting vines who value a stated duration and coverage area. Its one-pound package and 15-square-foot coverage make it a more focused choice than a bulk option.

#8

8. Organic Plant Magic Granules

• Weight: 4 lb
• Form: Granules

Best for: Monthly Mixed-Plant Feeding.

Why it ranks #8: The organic slow-release granules include fruit trees among their uses and can be top-dressed monthly, though they are not tree-specific.

Organic Plant Magic’s spreadable granules have a simple stated rhythm: apply to soil once per month or more, then water as usual. That routine suits growers who want one slow-release fertilizer for fruit trees alongside vegetables, flowers, shrubs, and house plants, indoors or outdoors.

The product lists fruit trees among a wide range of indoor and outdoor plants, making it useful where trees share a garden with vegetables, flowers, or house plants. Granules can be added to planting holes, mixed with soil, or top-dressed by hand or spreader, so application can match the planting task. The monthly-or-more schedule offers a recurring routine, and the slow-release description supports infrequent applications. Its listing also says the granules expand four times with water, a detail to account for during use.

Skip it if you want a tree-specific nutrient ratio; Espoma Tree-Tone lists a 6-3-2 analysis for shade, fruit, and ornamental trees.

Choose this adaptable granular option for gardeners feeding fruit trees alongside a varied indoor or outdoor planting. Hand or spreader top-dressing offers flexibility, while its monthly schedule is worth considering if you prefer fewer planned applications.

#9

9. Farmer's Secret Fruit Booster

• Weight: 8 oz
• Form: Liquid

Best for: Early-Season Fruit Trees.

Why it ranks #9: This concentrated liquid targets fruit trees during early growth; its weekly dilution directions are specific, but it is less broadly suited to trees.

Farmer’s Secret Fruit Tree Booster is positioned for the early growth cycle, from after dormancy until fruit starts to bud, when its phosphorus-rich formula supports a focused feeding window. The concentrated liquid uses a teaspoon-per-gallon dilution and weekly drip-line application, with peach, banana, and apple trees among its listed targets.

The product is formulated for fruit trees and specifically highlights early growth after dormancy through the start of budding, making that seasonal boundary central to its use. Its high phosphorus concentration is described as helping expand root systems, while the concentrated liquid is diluted at one teaspoon per gallon and applied weekly along the drip line. First-season trees use one teaspoon weekly; mature-tree directions allow up to two. This measured routine fits growers willing to mix and apply a liquid feed regularly.

Skip it if you need a fruit-tree fertilizer that feeds plants for up to two months; Dr. Earth Natural Wonder lists that duration.

Fruit-tree growers planning a measured feed during the early growth cycle are the best match for this concentrated liquid. The weekly dilution routine gives a defined workflow, but its stated seasonal focus may not suit anyone seeking year-round guidance.

#10

10. Farmer's Secret Citrus Booster

• Weight: 2.9 lb
• Form: Liquid

Best for: Weekly Citrus Feeding.

Why it ranks #10: The concentrated liquid is formulated for citrus trees and gives weekly dilution directions, but it is narrowly targeted rather than a general tree fertilizer.

A teaspoon diluted in a gallon of water makes Farmer’s Secret Citrus Tree Booster a concentrated liquid feed for citrus trees, including lemons, limes, and oranges. Its weekly drip-line directions give growers a repeatable routine, while the listed guidance also distinguishes first-season, mature, and indoor or container trees.

This liquid is formulated for all citrus trees and uses a dilution-based routine rather than direct granular application. The general direction is one teaspoon per gallon of water, applied weekly along the drip line; first-season trees use one teaspoon per week, while mature trees can receive up to two. For indoor or container trees, the stated guidance is to halve the dosage or apply every other week. Foliar or soil application is also listed, giving growers two stated application routes.

Skip it if you prefer monthly granules for mixed plantings; Organic Plant Magic lists once-monthly soil application for indoor and outdoor plants.

Choose this liquid for citrus growers comfortable measuring and diluting fertilizer on a weekly schedule. Its separate instructions for young, mature, and container trees help tailor use, but gardeners seeking less frequent applications may prefer a monthly granular routine.
