Best Fertilizer For Plumeria Plants: 10 Options Compared

#1 · Best Overall

1. TPS Plumeria Liquid

• Weight: 8 oz
• Form: Liquid

Best for: Liquid Feeding for Plumeria.

Why it ranks #1: Formulated for plumeria, it supports blooms, foliage, roots, and growth; directions specify 2 tablespoons mixed with 1 gallon of water.

A plumeria-specific liquid formula gives growers a direct way to feed tropical flowers in pots, patio containers, garden beds, and outdoor plantings. Its stated support for colorful blooms, foliage, roots, and fresh branch growth makes it relevant to gardeners seeking both flowering and fuller-looking plants.

The liquid form supports a measured watering routine: mix 2 tablespoons with 1 gallon of water, then apply as usual. Its tropical-plant nutrition is paired with claims for root development and effective water and nutrient uptake, connecting feeding to the plant’s foundations as well as its leaves and flowers. The formula is identified for plumeria and tropical flowers, while the listed uses span containers and garden beds, so it fits several common planting settings.

Skip it if you want a granular feed instead of a liquid to mix; Nelson NutriStar 5-30-5 is a listed granular alternative.

This suits plumeria growers who want a liquid feed for containers, patios, or garden beds and value support for roots, foliage, and blooms. Its application requires measuring and mixing with water before feeding.

#2 · Longest Release

2. Exotica Tropicals Nursery Grade

• Weight: 4 lb
• Form: Granules

Best for: Long-Release Nursery Pellets.

Why it ranks #2: This plumeria-specific nursery fertilizer combines coated pellets with a smaller instant-release portion and states a 5–6 month slow-release period.

Coated pellets with a stated 5–6 month slow-release period make Exotica Tropicals’ fertilizer an option for plumeria growers seeking a longer-lasting base feed. A smaller instant-release portion is also described to provide quick feeding and green-up at the first application.

The combination of slow-release coated pellets and a smaller instant-release portion pairs extended feeding with an initial nutrient response. The product includes micronutrients such as magnesium, manganese, and iron, supporting a broader nutrient profile for plumeria and frangipani. Directions also give distinct measures for potted plants and landscape use, with feeding every 6–8 weeks during the growing season. The listed foliar-spray option adds another application route alongside mixing with soil.

Skip it if you prefer capsules pressed into moist soil with a stated 14–21-day release window; EarthPods offers that application style.

This suits plumeria growers seeking coated pellets, an initial instant-release component, and directions for pots or landscapes. The 6–8-week growing-season schedule and soil or foliar application options should fit the planned routine.

#3 · Best Concentrate

3. HiThrive Plumeria Fertilizer

• Weight: 1.3 lb
• Form: Liquid

Best for: Seasonal Liquid Feeding Routine.

Why it ranks #3: The 16-ounce liquid bottle makes 16 gallons and includes directions for feeding every 1–2 weeks in the growing season.

One 16-ounce bottle is stated to make 16 gallons of liquid fertilizer, giving plumeria growers a defined batch yield for repeated feedings. HiThrive combines nitrogen, phosphorus, potassium, and six micronutrients to support foliage, roots, and flowers across plumeria varieties.

The label directions set different intervals for changing conditions: apply every 1–2 weeks during the growing season and every four weeks during cooler months. That schedule helps growers plan feeding around the seasons, while the liquid form is mixed with water before application. Nitrogen supports leafy growth, phosphorus supports roots, and potassium supports flowers; six micronutrients round out the formula. Its stated compatibility with all plumeria varieties makes it applicable across named cultivars.

Skip it if you want a feed applied less often than every one to two weeks during active growth; Exotica Tropicals offers a 5–6 month slow-release component.

Choose this for plumeria growers comfortable mixing liquid feed and following seasonal intervals, especially those wanting a stated batch yield and broad variety compatibility. Its frequent growing-season schedule is a key fit consideration.

#4 · Best Stated NPK

4. Nelson NutriStar 5-30-5

• Weight: 2 lb
• Form: Granules

Best for: High-Phosphorus Tropical Blooms.

Why it ranks #4: This granular food explicitly lists its 5-30-5 NPK ratio, five nitrogen sources, and micronutrients for plumeria and flowering tropical plants.

A 5-30-5 granular analysis puts phosphorus at the center of Nelson NutriStar’s plumeria and flowering-tropical formula. Its five nitrogen sources are presented as a way to provide constant feeding, while added sulfur and micronutrients target soil acidity and colorful blooms for gardeners managing tropical plants.

The granular form suits growers who prefer a solid feed, and the stated 5% nitrogen, 30% phosphate, and 5% soluble potash make the nutrient balance explicit. Nelson says five nitrogen sources ensure a constant feed, while higher phosphorus is intended to produce more blooms. Added elemental sulfur helps increase soil acidity, and specific micronutrients promote brilliant color. The formula also covers flowering tropicals, so it can serve more than plumeria alone.

Skip it if you prefer a liquid concentrate with a stated mixing schedule; HiThrive Plumeria Fertilizer is a liquid option with seasonal directions.

This is a fit for plumeria and other flowering-tropical growers who want granular feeding, a high-phosphorus analysis, and micronutrients. Application calls for protective gear and care to avoid inhaling fertilizer dust.

#5

5. Leaves & Soul 3-5-4

• Weight: 8 oz
• Form: Liquid

Best for: Balanced 3-5-4 Liquid Feed.

Why it ranks #5: The liquid is designed for plumeria and states a 3-5-4 formula intended to support roots, foliage, and consistent flowering.

A stated 3-5-4 formula gives Leaves & Soul Plumeria Fertilizer a defined nutrient balance for growers seeking liquid feeding. The brand connects that balance with strong roots, lush foliage, and consistent flowering, making the 8-ounce product a plumeria-focused choice for bloom and growth support.

The liquid form supports watering-based feeding, while the product’s safety information explicitly says to dilute it before use. Its 3-5-4 balance is presented as supplying nutrients for roots, foliage, and flowering, rather than emphasizing a single plant outcome. The formula is labeled for plumeria and is described as fast-acting. Growers should also follow the listed handling guidance: avoid skin and eye contact and store it in a cool, dry place.

Skip it if you want granules rather than a liquid that must be diluted; Cz Garden BloomBiscus is a granular tropical-plant food.

This is suited to plumeria growers who want a liquid fertilizer with a stated 3-5-4 balance and support for roots, foliage, and flowers. Dilution and careful handling are part of using the product.

#6 · Easiest Application

6. EarthPods Tropical Spikes

• Weight: 3.9 oz
• Form: Capsules

Best for: Low-Mess Capsule Feeding.

Why it ranks #6: The 100 capsules push into moist soil near the stem, and their nutrients release at the roots for 14–21 days during active growth.

Push-in capsules make EarthPods a distinctive option for plumeria growers who want to feed near the roots without mixing a liquid solution. The capsules release nutrients slowly for 14 to 21 days, and the product is listed for a wide range of tropical flowers beyond plumeria.

The application routine is press one or two capsules into moist soil near the stem and water, offering a direct alternative to measuring and mixing liquid fertilizer. Slow nutrient release over 14–21 days supports buds, leaf color, and roots while plants are actively growing and blooming. EarthPods are listed for many tropicals, including hibiscus, bougainvillea, and plumeria, which can simplify feeding across a mixed planting. Store the capsules in a cool, dry place.

Skip it if you want a granular fertilizer with a longer stated slow-release period; Exotica Tropicals lists coated pellets lasting 5–6 months.

This fits growers who prefer capsule-based root-zone feeding for plumeria and other tropical flowers, especially when mixing liquid is inconvenient. Its stated release window is 14–21 days during active growth and bloom.

#7

7. Cz Garden BloomBiscus

• Weight: 4 lb
• Form: Granules

Best for: Multi-Tropical Granular Feeding.

Why it ranks #7: This 4-pound granular food names plumeria among its tropical uses and lists a 10-4-12 formula with 2% iron and micronutrients.

A 10-4-12 analysis with 2% iron makes BloomBiscus a granular food for plumeria growers tending a broader collection of flowering tropicals. The listed plants include hibiscus, bird of paradise, bromeliads, and ixora, so one formula can serve several named tropical varieties alongside plumeria.

The granular form is suited to gardeners who prefer applying solid plant food, and the stated 10-4-12 analysis makes its nitrogen, phosphorus, and potassium balance clear. Its 2% iron and micronutrients add components beyond the primary nutrient ratio. The product is formulated for hibiscus and flowering tropicals, with plumeria among the specified plants, so it can cover a mixed tropical planting. Directions say to apply the product as directed.

Skip it if you want a stated application interval and dose rather than directions to apply as directed; Exotica Tropicals lists both for its fertilizer.

This suits gardeners feeding plumeria alongside several other flowering tropicals who want granular food with a stated NPK ratio and iron. Its supplied directions leave the specific application rate to the product instructions.

#8

8. GrowThrive Plumeria Liquid

• Weight: 350 g
• Form: Liquid

Best for: Organic Soil-Microbe Support.

Why it ranks #8: It is tailored to plumeria and describes a natural probiotic liquid with a soil-conditioning microbe blend, though no NPK ratio is provided.

More than 200 soil-support blends per milliliter distinguish this liquid plumeria food, giving gardeners a formula focused on soil health alongside plant nutrition. GrowThrive identifies it as natural and chemical-free, with a microbe blend intended to support balanced soil and improve nutrient availability for plumeria and blooming shrubs.

The liquid form makes this a fit for growers seeking a feed that also emphasizes soil conditioning, rather than a product described only through an NPK ratio. Its probiotic plant-food ingredients and soil-support microbe blend are presented as supporting microbial activity and nutrient availability. The product is tailored to plumeria and other blooming shrubs, so its stated scope extends beyond one plant type. Claims also include helping prevent seedling burn and over-fertilization.

Skip it if you want a stated NPK ratio to compare nutrient proportions; Leaves & Soul Plumeria Fertilizer lists a 3-5-4 formula.

This suits gardeners who prioritize an organic, liquid plumeria feed with soil and microbial support, including those also growing blooming shrubs. Buyers who select fertilizer by a published NPK ratio may prefer a product with that figure stated.

#9

9. Dr. Earth Exotic Blend Minis

• Weight: 16 oz
• Form: Powder

Best for: Organic Tropical Garden Blend.

Why it ranks #9: The 5-4-6 blend is described as organic and suitable for tropical and subtropical plants, including plumeria, but is not plumeria-specific.

A 100% organic and natural 5-4-6 blend gives Dr. Earth’s Exotic Blend a defined profile for plumeria and many other tropical or subtropical plants. Its listed scope includes palms, hibiscus, ferns, and bougainvillea, making it a broad-use option for mixed garden collections.

The powder form is a practical fit for growers who prefer a dry fertilizer rather than a liquid feed or capsule. Its 5-4-6 analysis gives nitrogen, phosphorus, and potassium proportions to compare, while the product is described for tropical and subtropical plants, including plumeria and flowering plants. Dr. Earth also states that the blend contains no GMOs, chicken manure, or sewage sludge, which may matter to gardeners assessing ingredient criteria.

Skip it if you need a stated feeding schedule and application dose; Exotica Tropicals provides intervals and measures for pots and landscapes.

This suits gardeners seeking an organic powder for plumeria within a mixed tropical or subtropical planting, with a stated 5-4-6 analysis. Consider the application guidance available with the product when planning a feeding routine.

#10

10. Grow More Hawaiian Bud and Bloom

• Weight: 1.5 lb
• Form: Powder

Best for: Water-Soluble Bloom Booster.

Why it ranks #10: This water-soluble 5-50-17 bloom booster mentions flowering tropicals, but its description emphasizes late-bloom and hydroponic use rather than plumeria.

A 5-50-17 analysis and water-soluble powder form make Grow More Hawaiian Bud and Bloom a high-phosphorus option for flower-focused feeding. Its urea-free formula is described for flowering tropical and near-tropical plants, while humic acid and micronutrients add further components to the bloom-oriented blend.

The high-phosphorus formula is intended to support bud formation, root development, flower color, and size, giving bloom-focused growers a clear reason to consider it. Because it is water soluble, it can be used in fertigation or as a foliar application, according to the supplied directions. The formula is also described for hydroponic production of cut flowers and as a starter or transplant solution. Its tropical-plant scope includes plumeria, orchids, and bromeliads.

Skip it if you want a plumeria-specific liquid with a balanced 3-5-4 analysis; Leaves & Soul Plumeria Fertilizer lists that ratio.

This fits growers focused on flowering tropicals who want a water-soluble, high-phosphorus powder usable in fertigation or foliar feeding. Its 5-50-17 balance is an important consideration for anyone seeking a less phosphorus-heavy formula.
