Best Fertilizer For Leyland Cypress: 10 Options Compared

#1 · Best Overall

1. TreeHelp Cypress Fertilizer

• Weight: 1.5 kg
• Form: Liquid

Best for: Cypress-specific slow-release nutrition.

Why it ranks #1: Specifically formulated for cypress, it provides slow-release nitrogen through the growing season and treats one large or two to three smaller trees.

A formula specifically for cypress, with slow-release nitrogen that continues through the growing season, is the key distinction of TreeHelp Premium Fertilizer. For Leyland cypress owners, that direct species fit and emphasis on root development provide a focused option instead of a general evergreen blend.

TreeHelp says its fertilizer promotes robust root development and provides slow-release nitrogen throughout the growing season, connecting the formula to both root support and extended feeding. The 1.5-kilogram product treats one large tree or two to three smaller or newly planted trees, which helps buyers estimate how it fits a planting. Complete instructions are included, though the supplied details do not specify a nutrient ratio or application method. The listing states that it is not available for sale in Washington.

Skip it if you are in Washington; Jobe’s Slow Release Evergreen Fertilizer Spikes list cypress among their suitable trees.

Choose TreeHelp if you want a cypress-specific fertilizer and are feeding one large tree or a small group of young trees. Its Washington sales restriction is a decisive location boundary, and the supplied details do not state a nutrient ratio.

#2 · Best Cypress Spikes

2. Jobe's Cypress Spikes

• Weight: 3.68 oz
• Form: Granules

Best for: Cypress-specific twice-yearly feeding.

Why it ranks #2: Its listed uses explicitly include cypress, with 11-3-4 NPK spikes and directions for applying twice yearly in early spring and late fall.

A cypress-specific label makes these Jobe’s 11-3-4 spikes a targeted choice for Leyland cypress, with the listing also naming arborvitae, pine, and cedar. Pre-measured spikes place nutrients below the surface near active roots, offering a straightforward alternative to spreading loose fertilizer across the surrounding soil.

The product calls for application twice a year, in early spring and late fall, which gives cypress owners a clear seasonal routine. Its pre-measured spikes are intended to supply nutrients below the surface where active roots grow, connecting the format to targeted placement rather than surface broadcasting. The listed 11-3-4 analysis helps buyers compare nutrient ratios, and the directions specify driving spikes one to two inches below the ground with a hammer and plastic spike cap.

Skip it if you want to avoid scheduled spike applications; TPS Nutrients Evergreen Tree Fertilizer is listed as a liquid plant food.

Choose this Jobe’s formula if your Leyland cypress benefits from a cypress-named product and you can manage spring and fall applications. Its directions specify a hammer and plastic spike cap, so account for those tools when planning the work.

#3 · Best 13-3-4 Formula

3. Jobe's Evergreen Spikes

• Weight: 16 oz
• Form: Sticks

Best for: Low-effort evergreen feeding.

Why it ranks #3: Made for evergreens, these 13-3-4 spikes are slow-release and list feeding for up to 90 days, though cypress is not named.

A slow-release 13-3-4 formula feeds evergreens for up to 90 days, making these Jobe’s spikes a practical option for Leyland cypress owners who want nutrients placed in the soil without scattering loose fertilizer. The spike format directs feeding around the tree, while rainfall handles the next step.

Each spike is formulated for evergreens, so this product has a clearer fit for cypress than a general tree-and-shrub blend. Drive the spikes into the ground around the tree, then let rain carry on the process; there is no liquid to mix or spread. The listed feeding period of up to 90 days suits buyers who prefer a slow-release approach, though it does not establish a once-a-year schedule. The 13-3-4 analysis gives the buyer a stated nutrient ratio to compare.

Skip it if you want a liquid application for an evergreen hedge; TPS Nutrients Evergreen Tree Fertilizer is listed as a liquid plant food.

Choose these spikes if your Leyland cypress needs an evergreen-formulated slow-release feed and you can place them in the ground. Their stated feeding window is up to 90 days, so plan around that interval rather than expecting year-long coverage.

#4 · Longest Listed Feed

4. SimplyGro Evergreen Spikes

• Weight: 3 lb
• Form: Sticks

Best for: Three-month conifer spike feeding.

Why it ranks #4: The 12-3-3 spikes are formulated for conifers and evergreens, and the listing says each spike feeds continuously for up to three months.

A 12-3-3 formula made for evergreens and conifers pairs with five-inch spikes that feed continuously for up to three months. That combination gives Leyland cypress owners a root-zone spike option with a stated feeding window, without requiring repeated liquid mixing during that period.

SimplyGro names evergreens, pines, firs, and other coniferous trees and shrubs as the target for its 12-3-3 formula, supporting its fit for Leyland cypress. Each five-inch spike is packed with nutrition intended to feed continuously for up to three months, so the product offers a defined interval for planning maintenance. The stick form places the feed in the ground rather than requiring a liquid application. Buyers should weigh that three-month span against their preferred feeding schedule.

Skip it if you want a liquid evergreen feed; TPS Nutrients Evergreen Tree Fertilizer is listed in liquid form for landscape and yard trees.

This is a fit for Leyland cypress owners who want conifer-oriented spike feeding and can work with a three-month maximum feeding period. Its five-inch sticks suit in-ground placement, while buyers seeking liquid application should choose a different format.

#5

5. Miracle-Gro Tree Spikes

• Weight: 3 lb
• Form: Sticks

Best for: Drip-line spike placement.

Why it ranks #5: These 15-5-10 spikes are listed for evergreen trees and deliver slow-release nutrients to roots; use the label chart to determine quantity.

Slow-release nutrients go directly to tree and shrub roots with Miracle-Gro’s spikes, giving Leyland cypress owners a defined placement routine rather than a liquid mixing step. The product also lists evergreen trees among its uses, while its 15-5-10 analysis offers a stated ratio for comparing plant-food formulas.

The instructions call for watering soil until it is sufficiently softened, then placing spikes around the plant’s drip line at least three feet apart. That sequence gives buyers a concrete placement method and helps keep the feeding around the root zone identified by the product. The spikes must be driven below the soil surface, using a foot or rubber mallet. Because the listing includes evergreen trees, this is a broadly usable tree-and-shrub option, not a cypress-only formula.

Skip it if you prefer a cypress-specific fertilizer; TreeHelp Premium Fertilizer for Cypress is formulated for cypress trees.

This fits a Leyland cypress owner who wants a root-directed spike routine and can follow drip-line spacing instructions. Allow time to soften the soil first, and choose another approach if preparing and driving individual spikes is inconvenient.

#6 · Highest Potassium Analysis

6. Almanac Evergreen Spikes

• Weight: 3 lb
• Form: Sticks

Best for: No-cap evergreen spike application.

Why it ranks #6: The evergreen and conifer product has a 10-4-10 formula and a hammer-in spike design, but its listing does not specifically name cypress.

The patented TruSpike can be hammered into the ground without a plastic cap or special equipment, making application the defining convenience of this Old Farmer’s Almanac evergreen food. Its 10-4-10 formula is listed for evergreens and conifers, giving Leyland cypress owners a spike-based feeding option.

Pre-measured spikes pair the 10-4-10 plant-food formula with a hammer-in application, so buyers can place individual feeds without a plastic cap or special equipment. The listing says the TruSpike will not break, crush, or smash, a durability claim relevant when driving it into the ground. Its stated use covers evergreen trees, firs, and conifers, a category that includes the cypress-focused use case. The supplied details do not give a feeding duration, so the interval cannot be planned from this listing alone.

Skip it if you need a stated feeding interval; Jobe’s Evergreen Tree & Shrub Fertilizer Spikes list feeding for up to 90 days.

This suits Leyland cypress owners who want pre-measured evergreen spikes and a hammer-only application method. Since the supplied details do not state a feeding duration, it is less useful for buyers who need to schedule applications by a defined interval.

• Form: Granules

Best for: Organic evergreen bed feeding.

Why it ranks #7: This 4-3-4 natural and organic granular fertilizer is for needle-leaf evergreens and includes 5% sulfur, making it a broad evergreen option.

Natural and organic ingredients, combined with Espoma’s Bio-tone formula, distinguish Evergreen-tone for buyers feeding Leyland cypress as part of a broader evergreen planting. Its 4-3-4 analysis and listed 5% sulfur provide concrete formulation details, while the label covers needle-leaf and broadleaf evergreens rather than only one tree type.

Espoma lists this granulated fertilizer for needle-leaf evergreens, a category that includes Leyland cypress, and also names pine, fir, spruce, and juniper. That broad plant coverage can simplify product selection for mixed evergreen beds. The natural and organic ingredient blend is enhanced with Bio-tone, and the 4-3-4 analysis includes 5% sulfur, giving buyers specific formulation information to weigh. The listing identifies planting and feeding as uses, making it relevant both when establishing evergreens and maintaining them.

#9

9. TPS Arborvitae Liquid

• Weight: 8 oz
• Form: Liquid

Best for: Liquid arborvitae hedge care.

Why it ranks #9: This liquid is formulated for arborvitae and evergreen hedges, not specifically cypress, so its listed target is less direct for Leyland cypress.

A liquid formula specifically made for arborvitae and evergreen hedges gives TPS Nutrients’ 8-ounce plant food a focused fit for hedge-style Leyland cypress plantings. The listing connects its nutrition to greener foliage, stronger roots, and new growth, making it a targeted alternative to broad tree-food products.

This product is framed around arborvitae, evergreen hedges, borders, and landscape plantings, so its use case aligns most closely with Leyland cypress grown as a hedge. The liquid form allows feeding without driving spikes into the soil, while the listed benefits include denser green foliage, stronger root systems, and improved water and nutrient uptake. Support for new growth and tip development also speaks to fuller growth. The listing provides no NPK ratio, so buyers cannot compare its analysis from the supplied details.

Skip it if you need a stated NPK ratio for comparison; Jobe’s Slow Release Evergreen Fertilizer Spikes list an 11-3-4 analysis.

Consider this for Leyland cypress planted as a privacy hedge when you want a liquid product associated with foliage, roots, and tip development. Its listing is arborvitae-focused and does not state an NPK ratio, a relevant boundary for comparison.

#10

10. TPS 10-10-10 Liquid

• Weight: 8 oz
• Form: Liquid

Best for: Balanced liquid tree feeding.

Why it ranks #10: Its equal 10-10-10 analysis is intended broadly for landscape trees and shrubs; the listing does not identify evergreen trees or cypress.

Equal 10-10-10 nitrogen, phosphorus, and potassium give this TPS Nutrients liquid fertilizer a clearly balanced profile for tree and shrub feeding. For Leyland cypress owners, the liquid format supports simple mixing and consistent nutrient delivery, while added iron and micros distinguish it from a three-number-only formula.

The product is listed for landscape trees, ornamentals, hedges, and garden plantings, making Leyland cypress a plausible use within its stated tree-and-shrub scope. Its liquid formula is described as allowing simple mixing and consistent nutrient delivery, which can suit buyers who prefer a prepared feeding solution over spikes or granules. Equal NPK values support roots, foliage, and structure, while iron and micros are also named in the title. No dilution rate is supplied in the provided details.

Skip it if you want an evergreen-specific formula; Jobe’s Slow Release Evergreen Fertilizer Spikes are listed for cypress and other evergreens.

This fits Leyland cypress owners seeking a balanced liquid for landscape trees and shrubs, especially when the same product may serve hedges and ornamentals. Its general-purpose listing is the boundary to weigh against an evergreen-specific fertilizer.
