Best Plant Food For Trees: Compare 10 Tree Fertilizers

#1 · Best Overall

1. Jobe's Tree Fertilizer Spikes

• Weight: 8.3 lb
• Form: Sticks

Best for: No-mix feeding for deciduous trees.

Why it ranks #1: Made for deciduous trees and shrubs, its 16-4-4 spikes feed all season below the surface, with no mixing or measuring required.

Spikes deliver nutrients below the soil surface without mixing or measuring, making Jobe’s Tree Fertilizer Spikes a straightforward choice for deciduous trees and shrubs. The directions place them around each tree’s dripline in early spring and late fall, aligning application with a defined seasonal routine.

The spike format puts nutrients below the surface, where the supplied description identifies active roots as the target, and avoids wasteful runoff, mess, hazards, or smells. Gardeners insert the spikes around the dripline rather than preparing a liquid solution or spreading loose granules. The 16-4-4 formula is described as feeding all season, and the product is listed for all deciduous trees and shrubs; application timing is early spring and late fall.

Skip it if you feed evergreens or hydrangeas; Miracle-Gro Tree & Shrub Plant Food Spikes lists both evergreen and acid-loving plants.

A useful choice for deciduous-tree owners who want a spike-based routine with no mixing or measuring. Its supplied directions specify dripline placement and seasonal timing, while gardeners with evergreens should choose a product listing those plants.

#2 · Best Organic Blend

2. Espoma Tree-Tone

• Weight: 4 lb
• Form: Powder

Best for: Organic feed for varied trees.

Why it ranks #2: Its 6-3-2 organic formula is intended for shade, fruit, and ornamental trees, including apple and peach trees, and needs no mixing.

A ready-to-use organic blend for shade, fruit, and ornamental trees gives Espoma Tree-Tone unusually broad tree coverage without a mixing step. Its 6-3-2 analysis includes 5% calcium, and the listed use includes apple and peach trees alongside shade trees and ornamentals.

Tree-Tone is a powder that can be applied as supplied, so gardeners do not need to dissolve it before feeding. Its stated spring-and-fall timing offers a seasonal routine, while the 6-3-2 analysis and 5% calcium give buyers specific nutrient information for planning. The product is intended for shade, fruit, and ornamental trees, making it relevant to mixed tree plantings rather than only one fruit family.

Skip it if you need a citrus-specific fertilizer with late-winter and post-bloom timing; Espoma Citrus-Tone lists those trees and seasons.

A sensible option for organic gardeners tending a mix of shade, fruit, and ornamental trees, including apples and peaches. Its supplied guidance centers on spring and fall use, so consider that seasonal routine before choosing it.

#3 · Best Root-Direct Spikes

3. Miracle-Gro Tree & Shrub Spikes

• Weight: 3 lb
• Form: Sticks

Best for: Root-zone spikes for yard trees.

Why it ranks #3: The 15-5-10 spikes release nutrients slowly near roots and suit deciduous, flowering, and evergreen trees, plus some acid-loving plants.

Slow-release spikes place nutrients directly near tree and shrub roots, giving Miracle-Gro Tree & Shrub Plant Food Spikes a targeted yard-care format. The listed uses include deciduous, flowering, and evergreen trees, plus acid-loving plants such as hydrangeas and azaleas.

Installation begins by watering the soil around the dripline until it is softened, then placing spikes at least three feet apart and driving each below the soil surface. That process avoids mixing a feed, but requires preparation and spacing around each plant. The 15-5-10 NPK ratio is supplied in the product description, and the slow-release nutrients are directed to roots for trees and shrubs in the yard.

Skip it if you want spikes specifically listed for all deciduous trees and shrubs; Jobe’s Tree Fertilizer Spikes gives that broader wording.

Consider these for yard trees and shrubs when root-zone spike placement appeals and the listed plant types match your garden. Expect to water first and follow the spacing and depth directions during installation.

#4 · Best Continuous Release

4. Scotts Evergreen & Tree Food

• Weight: 3 lb
• Form: Powder

Best for: Acid-loving trees and shrubs.

Why it ranks #4: This soil-applied formula feeds for up to two months and targets evergreens, dogwoods, magnolias, and other acid-loving trees and shrubs.

Up to two months of feeding makes Scotts Evergreen, Flowering Tree & Shrub Continuous Release Plant Food a fit for gardeners seeking a longer interval between applications. Its listed plants include evergreens, dogwoods, hydrangeas, and magnolias, with the formula also suited to many acid-loving trees and shrubs.

The powder is applied directly to soil, then raked into the top one to three inches so nutrients can release toward the root system. That simple soil-based routine avoids preparing a water-soluble feed, while the stated feeding period of up to two months reduces how often gardeners need to reapply. Scotts identifies vigorous root growth and lush foliage as intended benefits, and says the product will not burn plants when used as directed.

Skip it if you need a formula for citrus, avocado, or nut trees; Espoma Citrus-Tone specifically lists those tree types.

Consider this for gardeners feeding listed evergreens and flowering or acid-loving trees who want a soil-applied product with a multiweek feeding period. Follow the supplied directions to distribute it evenly and keep it away from the trunk.

#5 · Longest Listed Feed

5. Miracle-Gro Shake 'N Feed

• Weight: 8 oz
• Form: Granules

Best for: Longer feeding for flowering trees.

Why it ranks #5: Its granules provide continuous-release feeding for up to three months and are intended for flowering trees, shrubs, and acid-loving plants.

Up to three months of continuous-release feeding is the central advantage of Miracle-Gro Shake ’N Feed Flowering Trees & Shrubs Plant Food. Its granules are listed for flowering trees, shrubs, and other acid-loving plants, and can be used on in-ground or container plantings.

The granules feed for up to three months, giving gardeners a longer interval between applications than a weekly liquid routine. The formula contains kelp, earthworm castings, feather meal, and bone meal to feed soil microbes, and the supplied description says it nourishes above and below the soil. Its scope includes flowering trees, shrubs, and acid-loving plants, with use in both ground and containers.

Skip it if you need a formula for fruit trees such as apples and peaches; Espoma Tree-Tone lists those uses explicitly.

This suits gardeners feeding flowering trees or acid-loving shrubs who want granules with an extended feeding period and container flexibility. Its listed plant scope is narrower than an all-purpose formula, so match it to the trees you grow.

#6

6. Jobe's Organics Granular Fertilizer

• Weight: 4 lb
• Form: Granules

Best for: Organic feed for mixed gardens.

Why it ranks #6: The organic all-purpose granules include trees among their listed uses and are described as supporting beneficial soil microorganisms.

A granular all-purpose organic formula covers trees alongside vegetables, flowers, shrubs, and other plants, making Jobe’s Organics a practical option for mixed gardens. Its listed benefits include increased microorganism activity in soil, and the product description characterizes granular fertilizers as slower-release and longer-lasting.

The granular format lets gardeners apply one product across several plant types, rather than keeping a separate tree-only feed for a mixed garden. Jobe’s says the formula increases microorganism activity for healthier living soils and contains beneficial archaea that break down organic matter. The supplied general information notes that granular fertilizers typically release more slowly and last longer, which can support a less frequent-feeling routine than a fast-acting liquid, though no specific feeding interval is provided.

Skip it if you want a stated tree-spike schedule and below-surface placement; Jobe’s Tree Fertilizer Spikes lists both.

This suits gardeners who want an organic granular fertilizer for trees within a broader mixed planting. The product information does not give a tree-specific application interval, so it is a less defined choice for shoppers seeking a precise schedule.

#7

7. Espoma Citrus-Tone

• Weight: 4 lb
• Form: Granules

Best for: Citrus and fruit-tree care.

Why it ranks #7: Its 5-2-6 organic formula is tailored to citrus, fruit, nut, and avocado trees, making it useful but narrower than general tree foods.

Three seasonal application windows distinguish Espoma Citrus-Tone: late winter before bloom, spring after bloom, and fall. The granular organic fertilizer is listed for citrus trees as well as avocado and nut trees, giving growers with those tree types a targeted alternative to all-purpose plant food.

Citrus-Tone comes as granules, so it is spread over the entire tree or plant area rather than mixed into water. The supplied direction calls for four pounds per application and says to repeat as needed for continuous feeding. Its 5-2-6 analysis with 5% calcium provides a defined nutrient profile, while the listed citrus, avocado, and nut uses help buyers match it to their planting.

Skip it if you mainly feed shade or ornamental trees; Espoma Tree-Tone lists those uses and does not focus on citrus and fruit trees.

Choose this for gardeners managing citrus, avocado, or nut trees who can follow its seasonal schedule and spread granules across the plant area. Its tree-specific scope is less suited to a garden centered on shade trees.

#8

8. Farmer's Secret Citrus Booster

• Weight: 11.2 oz
• Form: Liquid

Best for: Concentrated feed for citrus containers.

Why it ranks #8: This concentrated liquid is made for citrus trees, with weekly diluted feeding directions and a reduced dose for indoor or container trees.

One teaspoon diluted in a gallon of water gives Farmer’s Secret Citrus Tree Booster a specific weekly routine for citrus growers. The concentrated liquid is listed for lemons, limes, and oranges, with container trees getting half the dosage or an every-other-week application.

The teaspoon-per-gallon instruction makes preparation concrete, while the weekly dripline application gives outdoor growers a repeatable feeding routine. For first-season trees, the supplied directions specify one teaspoon weekly; mature trees may receive up to two teaspoons weekly. Container trees use half the dosage or can be fed every other week, which adapts the schedule to indoor and patio growing without changing the product’s citrus focus.

Skip it if you prefer ready-to-use tree food without liquid preparation; Espoma Tree-Tone is ready to use and requires no mixing.

A strong fit for citrus growers who want a measured liquid routine, including separate guidance for first-season, mature, and container trees. The dilution and recurring applications suit owners comfortable preparing feed with water.

#9

9. TPS Nutrients Lime Tree Fertilizer

• Weight: 8 oz
• Form: Liquid

Best for: Potted lime and citrus trees.

Why it ranks #9: The liquid is designed for lime and citrus trees in gardens or containers, but its listed use is more specialized than broader tree formulas.

A liquid formula specifically for lime and citrus trees gives TPS Nutrients Lime Tree Fertilizer a focused role in container or garden citrus care. The product is described as supporting roots, tree strength, and fruit development, with use listed for backyard orchards, patios, and potted trees.

Its liquid form suits growers who prefer a feed that can be handled as a liquid rather than spread as granules or inserted as spikes. The product description connects its balanced nutrition to steady growth and seasonal harvests, while the listed garden and container uses cover both backyard plantings and patio pots. The supplied information does not give a dilution rate or application schedule, so buyers should rely on the product directions for those details.

Skip it if you want a clearly stated weekly dilution routine; Farmer’s Secret Citrus Tree Booster gives teaspoon-per-gallon directions.

A focused option for lime and citrus growers tending backyard trees, patios, or pots and seeking liquid plant food. Check the product’s directions for dilution and timing, since those specifics are not included in the supplied details.

#10

10. Miracle-Gro Water Soluble Food

• Weight: 1.5 lb
• Form: Powder

Best for: Quick boost for mixed plantings.

Why it ranks #10: This 24-8-16 all-purpose powder includes trees among many indoor and outdoor uses, but it is not specifically formulated for tree care.

Water-soluble powder starts feeding immediately, giving tree owners a quick application option when trees share a garden with flowers, vegetables, or houseplants. Miracle-Gro lists it for indoor and outdoor plants, including trees, and its 24-8-16 analysis makes this a broad-use formula rather than a tree-only product.

Because the powder dissolves in water and starts working instantly, it suits gardeners who want a rapid feed rather than a slow-release schedule. The listed 24-8-16 analysis and coverage across indoor and outdoor plants, including trees, make one formula usable across mixed plantings. It can also be used with a Miracle-Gro Garden Feeder; the supplied directions say one refill packet covers 500 square feet in about a stated time, though that time is not specified in the provided details.

Skip it if you want a tree-specific, no-mixing application; Jobe’s Tree Fertilizer Spikes are inserted at the dripline.

A practical pick for gardeners feeding trees alongside other plant types, especially when a quick water-soluble application is useful. Choose another format if you prefer direct soil application without mixing or repeated liquid feeding.
