Best Liquid Fertilizer For Trees for Landscape and Specialty Trees

#1 · Best Overall

1. HiThrive Tree and Shrub Fertilizer

• Form: Liquid
• Weight: 1.3 lb

Best for: Frequent landscape feeding.

Why it ranks #1: Broadly suited to tree and shrub varieties, it lists nitrogen, phosphorus, potassium, and micronutrients, plus a clear rate of one tablespoon per gallon.

A 16-ounce bottle makes 16 gallons of liquid plant food, giving tree and shrub owners a clearly stated dilution yield for repeated growing-season applications. HiThrive also specifies nitrogen, phosphorus, potassium, and micronutrients, connecting foliage, root support, and resilience in one formula.

Mix one tablespoon per gallon of water and apply every one to two weeks during the growing season or as needed. That schedule gives gardeners a defined routine for landscape feeding, while the stated 16-gallon yield from the 16-ounce bottle helps estimate how much prepared fertilizer is available. The formula is described for all tree and shrub varieties, with examples including oak, maple, dogwood, holly, lilac, and camellia, making it relevant to mixed plantings.

Skip it if you need fertilizer specifically focused on fruit-tree early growth; Farmer's Secret Fruit Tree Booster gives a weekly drip-line direction.

A practical option for gardeners feeding several landscape trees and shrubs on a recurring schedule. Its directions are geared to growing-season use every one to two weeks, rather than a single annual feeding.

#2 · Landscape Pick

2. Bloom City Tree & Shrub Fertilizer

• Form: Liquid
• Weight: 2 lb

Best for: Landscape trees and shrubs.

Why it ranks #2: Designed for landscape trees and ornamental shrubs, it specifically targets root strength and fuller foliage across hedges, foundation plantings, and backyard trees.

A 32-ounce liquid format paired with tree-and-shrub positioning makes Bloom City relevant for landscape beds, hedges, foundation plantings, and backyard trees. Its stated benefits center on deeper roots and fuller foliage, linking below-ground support with a denser-looking landscape.

Bloom City describes balanced nutrition for outdoor plants and steady growth, which suits gardeners caring for ornamental shrubs alongside trees. The root-strength and dense-foliage focus connects the formula to both establishment and visible landscape fullness, while the listed settings—hedges, foundation plantings, and backyard trees—cover several common planting layouts. Its liquid form is specified, but the supplied product information does not provide a dilution rate or application frequency, so buyers must rely on directions not included here.

Skip it if you need a stated mixing schedule for frequent feeding; HiThrive Tree and Shrub Fertilizer specifies a gallon dilution and growing-season interval.

A fit for gardeners looking to support trees and shrubs across hedges, foundation beds, and backyard plantings. The listing names the intended landscape uses but does not give a feeding schedule.

#3 · Listed NPK Ratio

3. TPS 10-10-10 Tree & Shrub Fertilizer

• Form: Liquid
• Weight: 8 lb

Best for: Equal-ratio landscape nutrition.

Why it ranks #3: The one-gallon formula lists equal 10-10-10 nitrogen, phosphorus, and potassium, offering a clearly specified balanced option for landscape trees and shrubs.

Its explicitly stated 10-10-10 ratio provides equal nitrogen, phosphorus, and potassium for landscape trees and shrubs. The one-gallon liquid format and mixing-oriented design suit buyers preparing fertilizer for ornamentals, hedges, and garden plantings rather than targeting one tree species.

Equal NPK proportions give shoppers a clearly defined general-purpose nutrient balance, while the listed iron and micronutrients extend the formula beyond the three primary nutrients. The liquid form is described as allowing simple mixing and consistent nutrient delivery, which can support a repeatable landscape-feeding workflow. Its use cases include ornamentals, hedges, and garden plantings, making it relevant to mixed outdoor settings. The supplied information does not state a dilution ratio or application frequency.

Skip it if you need a named fruit-tree formula and weekly drip-line directions; Farmer's Secret Fruit Tree Booster specifies that use.

Choose this for broad landscape tree and shrub feeding when an equal 10-10-10 ratio and a one-gallon liquid format suit your routine. The supplied listing leaves dilution and timing unspecified.

#4

4. TPS Tree and Shrub Fertilizer

• Form: Liquid
• Weight: 0.32 kg

Best for: Small-scale landscape feeding.

Why it ranks #4: This general tree-and-shrub formula supports roots and foliage, suits landscape and foundation plantings, and comes in a compact 8-ounce bottle.

An 8-ounce liquid format and broad tree-and-shrub positioning suit gardeners maintaining ornamental plantings, home landscapes, or foundation shrubs on a smaller scale. The product emphasizes roots, fuller growth, and leaf color while calling for nutrition without overfertilizing established plants.

Its stated balance is intended to support long-term plant health without overfertilizing or stressing established plants, a useful distinction for gardeners caring for mature landscape specimens. The listed settings include ornamental plantings and foundation shrubs, so the formula is not limited to one named tree species. The compact 8-ounce format may suit a smaller feeding need, though the supplied information does not specify a dilution rate or application schedule. Safety directions include keeping it from children and pets and avoiding skin and eye contact.

Skip it if you need a larger specified supply for evergreen trees; TPS Nutrients Evergreen Tree Fertilizer comes in a one-gallon size and targets conifers.

A reasonable fit for smaller-scale care of established ornamental trees and foundation shrubs when balanced growth is the aim. Check the product directions for mixing and timing, which are not given in the supplied details.

#5 · Specified 6-4-6

5. Leaves & Soul Evergreen Tree Fertilizer

• Form: Liquid

Best for: Balanced evergreen and plant care.

Why it ranks #5: Its concentrated liquid lists a 6-4-6 NPK ratio and is directed toward evergreen trees, with a 32-ounce size available for repeated plant care.

Its 6-4-6 NPK blend gives evergreen owners a specific balance of nitrogen, phosphorus, and potassium in a concentrated liquid. That combination supports roots, greener foliage, and leaf development, while the broad indoor-and-outdoor plant positioning makes it useful beyond a single tree type.

The concentrate mixes with water before application, so feeding can be incorporated into a watering routine rather than applied as a ready-to-use liquid. Its stated 6% nitrogen, 4% phosphorus, and 6% potassium figures make the nutrient balance clear for shoppers comparing formulas. The product is presented for evergreen trees as well as everyday indoor and outdoor plant care, which suits a gardener who wants one formula for multiple plantings. Available sizes include 8 and 32 ounces.

Skip it if you want a formula specifically identified for citrus fruiting; TPS Nutrients Lemon Tree Fertilizer targets lemon and citrus trees.

Choose this for evergreen care alongside broader indoor or outdoor plant feeding, especially if a stated 6-4-6 balance matters. It is a concentrate, so plan to mix it with water before use.

#6 · Gallon Evergreen

6. TPS Evergreen Tree Fertilizer

• Form: Liquid
• Weight: 8 lb

Best for: Large-volume evergreen care.

Why it ranks #6: Made for evergreen and conifer trees, this one-gallon liquid formula targets needle health, roots, and new shoot development for landscape plantings.

A one-gallon liquid format gives evergreen and conifer owners a larger listed quantity for landscape and yard-tree care. Its stated focus on greener needles, healthy roots, and new shoot development connects visible evergreen condition with ongoing tree growth.

The product is positioned for evergreen and conifer trees, with benefits that include denser green foliage, new shoots and branches, and root development for water and nutrient uptake. Those combined aims suit gardeners maintaining outdoor evergreens across a yard or garden. The directions specify mixing at a 2:1 ratio with water, giving buyers a stated preparation step before use. Safety information says to keep it away from children and pets and not to ingest it.

Skip it if you want a specialized formula for Japanese maple foliage color; TPS Nutrients Japanese Maple Tree Fertilizer is specifically identified for that tree.

A fit for yard and landscape owners feeding evergreen or conifer trees who want a gallon-sized liquid and can follow the stated water-mixing ratio. Its focus is evergreens, not citrus or fruit trees.

#7

7. Farmer's Secret Fruit Tree Booster

• Form: Liquid
• Weight: 2 lb

Best for: Early-cycle fruit-tree feeding.

Why it ranks #7: The concentrated formula is made for fruit trees and specifies one teaspoon per gallon weekly along the drip line, particularly during early growth.

A one-teaspoon-per-gallon dilution makes this phosphorus-rich concentrate especially suited to fruit-tree feeding after dormancy and before fruit starts to bud. Its guidance calls for weekly application along the drip line, tying the feeding method to the tree's root zone.

Farmer's Secret positions this formula for all fruit trees, naming peach, banana, and apple among its examples. The early-growth-cycle timing gives growers a defined seasonal window, while the drip-line direction helps place the diluted fertilizer around the tree rather than treating the trunk as the target. A stated concentration of one teaspoon per gallon and a 32-ounce bottle that can last a full season for a mature tree make dilution central to its use.

Skip it if you want a fertilizer for evergreen needles rather than fruit production; TPS Nutrients Evergreen Tree Fertilizer targets evergreen and conifer trees.

Consider it for fruit-tree owners following the specified early-season window and weekly drip-line routine. Its concentration requires dilution, and its stated timing is narrower than year-round general landscape feeding.

#8

8. TPS Lemon Tree Fertilizer

• Form: Liquid
• Weight: 8 oz

Best for: Lemon and citrus growers.

Why it ranks #8: This citrus-specific liquid supports lemon tree roots, shoots, and fruit development, making it a more focused choice than a general landscape formula.

Its lemon-and-citrus focus connects root support with fruit development, giving citrus growers a targeted liquid option rather than a general tree fertilizer. The listed use cases include patios, orchards, and backyard plantings, accommodating both container-grown lemon trees and in-ground citrus.

The formula is described as supporting healthy roots that help lemon trees take up water and nutrients, alongside fresh shoots and stems for fuller growth. It also targets fruit development and seasonal harvests, making the stated benefits relevant across both canopy growth and production. Its garden-and-container positioning gives patio growers as well as orchard and backyard growers a potential fit. Application safety information recommends gloves and safety glasses and keeping the product away from children and pets.

Skip it if you are feeding arborvitae hedges rather than citrus; TPS Nutrients Arborvitae Tree Fertilizer is specifically positioned for evergreen hedges.

A targeted choice for lemon and other citrus trees in containers or the ground, particularly when fruit development is part of the goal. Follow the stated handling precautions during application.

#9

9. TPS Arborvitae Tree Fertilizer

• Form: Liquid
• Weight: 2 lb

Best for: Arborvitae hedge maintenance.

Why it ranks #9: Made for arborvitae and evergreen hedges, it targets dense green foliage and root strength but is less broadly applicable than general tree formulas.

Specific arborvitae and evergreen-hedge positioning makes this liquid fertilizer a focused choice for privacy screens and borders. Its described benefits include denser green foliage, new growth, and stronger tips, addressing the visual fullness that matters in a maintained hedge.

The product also supports root development for improved water and nutrient uptake, pairing canopy-focused claims with below-ground support. That combination is relevant to arborvitae in yard plantings, borders, or privacy hedges where both healthy growth and fuller appearance matter. The 32-ounce liquid format is specified, but no mixing ratio or application timing appears in the supplied information. Buyers looking for a precise feeding routine should therefore check the product's own directions before applying.

Skip it if you need a stated schedule for mixed tree and shrub feeding; HiThrive Tree and Shrub Fertilizer lists a dilution and growing-season interval.

Choose it for arborvitae screens, borders, and other evergreen hedge plantings where foliage density and root support are priorities. The listing does not supply a feeding interval or dilution ratio.

#10

10. TPS Japanese Maple Tree Fertilizer

• Form: Liquid
• Weight: 9.6 oz

Best for: Japanese maple foliage focus.

Why it ranks #10: This liquid is tailored to Japanese maples and supports foliage color and roots, so its narrow tree-specific fit makes it least versatile for general tree care.

Specific Japanese maple positioning sets this liquid plant food apart for gardeners seeking support for ornamental foliage color and root development. Its stated uses include yard trees, containers, and decorative landscapes, so the same specialized focus can fit a planted specimen or a potted maple.

The formula is described as supporting rich leaf color, fresh leaf and branch growth, and healthy roots. Those goals speak to both the visible canopy and the tree's foundation, making it relevant when maintaining an ornamental Japanese maple rather than feeding a general mixed landscape. Its suitability for containers as well as yard plantings also gives maple owners flexibility in where they use it. The supplied listing identifies an 8-ounce liquid format, without giving a mixing rate.

Skip it if you are feeding mixed landscape trees and shrubs; TPS Nutrients Tree and Shrub Fertilizer is positioned for broader landscape use.

Choose it for an ornamental Japanese maple in a garden bed or container when foliage color and root support are priorities. The listing does not provide a mixing schedule, so it offers less application guidance.
