Best Fertilizer For Citrus: Compare 10 Tree Foods

#1 · Best Overall

1. Espoma Citrus-Tone 8 lb

• Weight: 8 lb
• Form: Granules

Best for: Larger-bag organic citrus feeding.

Why it ranks #1: This citrus-specific organic granular fertilizer states a 5-2-6 analysis with 5% calcium and gives drip-line application directions for citrus trees.

Espoma’s 8-pound Citrus-Tone bag pairs a 5-2-6 analysis with 5% calcium and its Bio-tone formula, offering the same broad tree coverage in a larger listed quantity. It is specified for citrus as well as fruit, nut, and avocado trees.

The granules are listed for lemons, limes, oranges, Meyer lemons, avocado, and nut trees, making the formula relevant to a mixed planting. Espoma recommends applying around the drip line in late winter before bloom, spring after bloom, and fall, then watering thoroughly. The instructions say no mixing is required, so application is a soil-spreading task rather than solution preparation. The 8-pound quantity suits growers planning repeated seasonal use across their listed plants.

Skip it if you need only a smaller listed bag; Espoma Citrus-Tone 5-2-6 is also available in a 4-pound size.

A fit for organic-minded growers with several citrus, fruit, nut, or avocado plants who want seasonal granular feeding without mixing. Consider the 8-pound quantity against the size of your planting before choosing this bag.

#2 · Smaller Organic Bag

2. Espoma Citrus-Tone 4 lb

• Weight: 4 lb
• Form: Granules

Best for: Organic multi-tree growers.

Why it ranks #2: It offers the same stated 5-2-6 analysis and 5% calcium as the larger bag, in a 4-pound format for smaller needs.

Espoma’s 5-2-6 granular formula includes 5% calcium and its Bio-tone blend, giving citrus growers a specified nutrient analysis for seasonal feeding. It also covers fruit, nut, and avocado trees, so one product can serve a mixed home orchard rather than citrus alone.

The granules are listed for lemons, limes, oranges, Meyer lemons, avocado, and nut trees, which makes them a practical fit when several of those plants share a garden. Espoma recommends use in late winter before bloom, spring after bloom, and fall; the directions call for spreading 4 pounds evenly over the plant area and repeating as needed for continuous feeding. That schedule and broad plant list help organize care, though each application involves measuring and spreading granules.

Skip it if you want a feeding interval of up to three months; Miracle-Gro Shake 'N Feed Citrus lists that duration.

Choose this for an organic-minded grower feeding citrus alongside fruit, nut, or avocado trees and able to spread granules seasonally. The listed 4-pound application amount may be more than a small container tree needs.

#3 · Extended Feeding

• Form: Granules

Best for: Extended-interval tree feeding.

Why it ranks #3: Its slow-release formula feeds for up to three months and includes potassium, magnesium, sulfur, and iron for container or in-ground trees.

Miracle-Gro Shake ’N Feed feeds citrus, avocado, and mango plants for up to three months, offering a defined interval between applications. Its listed micronutrients include potassium, magnesium, sulfur, and iron, making it a fit for growers seeking those nutrients alongside the feeding routine.

This granular food is listed for container and in-ground plants, as well as indoor and outdoor use, so it can serve trees in different growing setups. The directions place it in the root zone at the label’s recommended rate and call for thorough watering afterward. The up-to-three-month feeding period can reduce how often a grower schedules applications, while the named micronutrients give the formula a specific nutrient profile for citrus, avocado, and mango.

Skip it if you want a concentrated liquid mixed into weekly watering; Farmer's Secret Citrus Tree Booster provides that schedule.

A good fit for citrus, avocado, or mango growers who want granular feeding for indoor or outdoor containers and in-ground trees. Follow the label rate and plan to water thoroughly after applying it.

#4 · Organic Nutrient Detail

4. Down to Earth Citrus Mix

• Weight: 1 lb
• Form: Granules, Powder

Best for: Organic citrus nutrient mix.

Why it ranks #4: The OMRI-listed 6-3-3 mix includes calcium, sulfur, iron, and zinc, with guidance for citrus applications three to four times yearly.

Down to Earth Citrus Mix combines a 6-3-3 analysis with calcium, sulfur, iron, and zinc, giving organic citrus growers a named set of nutrients beyond its NPK ratio. Its OMRI listing and soil-surface or planting-mix application options support different garden workflows.

The listed ingredient sources include feather meal, fish bone meal, alfalfa meal, langbeinite, basalt, kelp, and humic acids derived from leonardite. Growers can apply the mix to the soil surface or incorporate it during planting, then water it in either way. For established citrus, the supplied guidance says most varieties need feeding three to four times per year, with typical applications in late winter, late spring, and early fall; that provides a seasonal planning framework.

Skip it if you want a citrus fertilizer listed for mango trees too; Miracle-Gro Shake 'N Feed Citrus is listed for citrus, avocado, and mango.

Choose this for organic citrus care when you want a 6-3-3 mix, named secondary nutrients, and either surface or planting-time application. Its guidance calls for watering in and describes three to four feedings annually for most citrus varieties.

5. Jobe's Organics Fruit & Citrus

• Weight: 4 lb
• Form: Granules

Best for: OMRI-listed organic granules.

Why it ranks #5: This OMRI-listed organic granular fertilizer has a stated 3-5-5 NPK and recommends application every four to eight weeks.

Jobe’s Organics pairs a 3-5-5 analysis with OMRI listing for organic gardening, giving fruit and citrus growers a clearly identified granular option. Its application guidance calls for feeding every four to eight weeks or as needed, which suits gardeners who prefer recurring soil applications.

The granules are formulated for fruit and citrus plants and trees, and the listed organic ingredients include feather meal, bone meal, processed poultry manure, potash sulfate, and endomycorrhizae. Jobe’s describes the product as avoiding wasteful runoff, mess, hazards, and smells, relevant for gardeners managing applications around home growing areas. The four-to-eight-week guidance gives a recurring schedule, so this is a better fit for growers willing to keep up with regular feeding than those seeking seasonal-only applications.

This suits organic gardeners feeding fruit and citrus plants who want granular applications and can maintain a four-to-eight-week routine. Its OMRI listing is relevant to certified-organic food production; the schedule may not suit seasonal-only care.

#6

6. Farmer's Secret Citrus Booster

• Weight: 11.2 oz
• Form: Liquid

Best for: Concentrated weekly liquid feeding.

Why it ranks #6: The concentrated liquid is made for citrus and gives a specific dilution of one teaspoon per gallon, with weekly application guidance.

Farmer’s Secret specifies one teaspoon per gallon of water, making its concentrated liquid a measured option for growers who prefer feeding citrus through a diluted solution. The directions distinguish first-season and mature trees, and also adjust the dose for indoor or container plants.

The weekly routine calls for applying the diluted solution along the drip line, with one teaspoon for first-season trees and up to two teaspoons for mature trees. Indoor and container trees use half the dosage or an every-other-week schedule, giving growers a stated adjustment for smaller growing setups. Its liquid form and concentrate make measuring and mixing part of each feeding, while the product is listed for citrus including lemons, limes, and oranges.

Skip it if you prefer granules with seasonal application guidance; Espoma Citrus-Tone 5-2-6 lists late-winter, spring, and fall use.

Choose this for citrus growers comfortable measuring a concentrate and following a weekly routine, especially those who need separate guidance for young, mature, or container trees. Keep the dilution and handling directions in mind.

7. TPS Nutrients Citrus Liquid

• Weight: 8 oz

Best for: Liquid feed for potted citrus.

Why it ranks #7: This liquid formula is specified for citrus varieties and potted or outdoor trees, with listed support for fruit, shoots, leaves, and roots.

TPS NUTRIENTS’ liquid citrus formula is listed for both potted and outdoor trees, giving growers one product option across container and garden settings. The supplied facts connect its support for roots, shoots, leaves, flowering, and fruit set to several stages of citrus growth.

The product targets oranges, lemons, limes, and other citrus varieties, with listed support for flowering, fruit set, and consistent tree performance. Additional facts describe fresh shoot and leaf development as well as roots that support water and nutrient uptake. Its liquid form is described as fast-absorbing, which may suit growers seeking a liquid feeding method for containers or outdoor plantings. The instructions say to mix with water as directed, so concentrate handling and dilution are part of use.

Skip it if you prefer a solid granular product that needs no mixing; Espoma Citrus-Tone 5-2-6 is applied to soil without mixing.

Choose this liquid for potted or outdoor citrus when you want support for flowering, fruit set, shoots, leaves, and roots. It requires water mixing as directed, so it is not the simplest fit for growers avoiding liquid preparation.

#8

8. TPS Nutrients Lemon Liquid

• Weight: 8 oz
• Form: Liquid

Best for: Lemon-focused liquid nutrition.

Why it ranks #8: The liquid is specifically made for lemon and citrus trees and described for garden and container use, though its listed details focus on lemons.

TPS NUTRIENTS’ liquid plant food specifically targets lemon and citrus trees, with listed support for roots, shoots, stems, and fruit development. Its stated suitability for patios, orchards, and backyard plantings gives lemon growers a product framed for both container and garden settings.

The formula is presented for lemon and citrus plants, while additional product facts connect root development with water and nutrient uptake and mention fresh shoot and stem development. That combination speaks to growers looking beyond fruit alone when caring for a tree.

#9

9. Miracle-Gro Fruit & Citrus Spikes

• Weight: 3.8 lb
• Form: Sticks

Best for: Twice-yearly tree spike feeding.

Why it ranks #9: The sticks suit buyers seeking a solid, soil-driven format; directions place them around the drip line, and the listed feeding schedule is twice yearly.

Miracle-Gro’s fruit and citrus food comes as spikes with a twice-yearly application schedule, giving tree growers a placement-based alternative to spreading loose granules. It is listed for apple, orange, lemon, lime, and avocado trees, as well as palm trees.

The instructions call for watering the soil around the drip line until softened, selecting the number of spikes from the product chart, spacing them at least three feet apart, and driving them fully below the soil surface. That sequence makes placement around each tree the main task rather than spreading food over an area. The twice-yearly schedule reduces feeding occasions, but spike placement requires accessible soil around the drip line.

Skip it if you want a liquid for container citrus; TPS NUTRIENTS Citrus Fertilizer – Liquid Plant Food for Bigger Harvests is listed for potted trees.

A fit for growers feeding fruit or citrus trees who prefer twice-yearly spike placement over recurring granular applications. The method requires access to the drip line and soil that can be softened before installation.

Why it ranks #10: The 2-pound granular product is listed for citrus and indoor or outdoor plants, but the supplied details do not state its NPK analysis or application schedule.

GARDENWISE lists its granular fertilizer for indoor and outdoor citrus, including orange, lime, avocado, and lemon trees. Its title identifies balanced NPK and vital micronutrients, while the verified product facts also describe support for overall growth, flowering, and fruiting.

The named plant list makes this a candidate for growers caring for citrus and avocado in indoor or outdoor settings. Its granular form distinguishes the application method from liquid feeds, while the product description highlights all-purpose nutrition and support for flowering and fruiting. The supplied information gives no application timing or rate, so buyers who plan care around a precise recurring schedule will need details beyond those provided here before establishing a routine.

Skip it if you need a stated citrus feeding schedule; Espoma Citrus-Tone 5-2-6 lists late-winter, spring, and fall application timing.

Consider this for indoor or outdoor citrus and avocado growers seeking granules with listed support for overall growth, flowering, and fruiting. The supplied details do not give a rate or schedule, which limits planning a precise routine.
