Getting a jasmine vine to bloom can feel like a guessing game. You water it, you talk to it, and sometimes it just… sits there. The real secret is giving the plant the exact nutrients it craves — the right NPK ratio turns a stubborn vine into a wall of fragrant flowers.

You want more blooms and stronger vines from your jasmine, whether it is a potted star jasmine indoors or a Confederate jasmine climbing a trellis. This roundup of the jasmine plant fertilizer options picks the formulas that real owners say deliver exactly that.
Our Picks at a Glance
How To Choose The Best Jasmine Plant Fertilizer
Jasmine is a hungry plant, especially when it is actively growing or setting buds. The right liquid fertilizer feeds the roots quickly and encourages the kind of growth that leads to clusters of white, highly fragrant flowers. Here is what separates a great jasmine feed from an average one.
The NPK Ratio
The three numbers on the bottle (nitrogen, phosphorus, potassium) control different parts of the plant’s life. A higher middle number (phosphorus) is what drives bloom production. For jasmine, a ratio where phosphorus is the middle or second-highest number is ideal — it tells the plant to focus energy on flowers rather than just leaves.
Concentrate vs Ready-to-Use
Nearly all the best options come as a concentrated liquid that you mix with water yourself. A small bottle, 8 to 32 ounces, can make dozens of gallons of feed. That means lower cost per feed and less plastic waste. The trade-off is that you need to measure — usually a teaspoon or a capful per gallon of water — but the control is worth the extra step.
Indoor vs Outdoor Use
If your jasmine lives in a pot inside, you want a formula that won’t build up salts in the soil. Outdoor plants in the ground or in large trellis pots handle a higher concentration better. The best pick for you depends on where the plant lives.

In‑Depth Reviews
1. Perfect Plants Liquid Jasmine Fertilizer
Our pick — 4.5★ from 700+ verified ratings; the strongest balance of quality and price.
The all-rounder that turns stubborn vines into blooming machines within a week.
This 8-ounce bottle delivers a 9-3-6 NPK ratio — meaning it carries a healthy dose of nitrogen for leaf growth while keeping phosphorus high enough to push those fragrant blooms. Buyers report that after just three weekly applications, their jasmine produced new vine sprouts over 6 inches long. That kind of fast, measurable response is exactly what you want from a concentrate.
What wins people over is the sheer consistency. The bottle is resealable, so the concentrate stays fresh for months between feedings. You only need a small amount — a teaspoon per gallon of water — and the formula is specifically tailored to the Jasminum family, not a generic houseplant feed. One owner noted it revived a stagnant lantana too, producing 10 new flower buds in a single week. The crowd of over 700 owners backs this as a reliable performer, with functionality and effectiveness being the most-cited reasons for the high praise.
The trade-off is that an 8-ounce bottle makes fewer total gallons than larger competitors — so if you have a massive trellis or several outdoor vines, you will reorder faster than you might like.
Liquid jasmine booster: The 9-3-6 ratio is a proven bloom-booster for potted and indoor jasmine. Owners consistently report new sprouts and more flowers within days.
Small bottle size: At 8 fluid ounces, (8 oz vs 16 oz), so plan for a second bottle if you are feeding a large garden.
Budget-friendly choice: you want a no-guess formula that has been tried by hundreds of jasmine owners and delivers visible results in under a week.
Check quantity first: you need maximum volume per dollar — the HiThrive 16-ounce bottle makes 96 gallons and offers more feed per drop.
2. HiThrive 16oz Jasmine Fertilizer
The gallon-stretcher that keeps eight types of jasmine happy with one bottle.
This is the volume champion. A single 16-ounce bottle makes 96 gallons of feed, (16 oz vs 8 oz). That matters if you have a collection of jasmine plants — one owner said they have 8 different types and “all seem to improve daily with this food.” The formula is rich in nitrogen for leaves, phosphorus for blooms, and potassium for resilience, plus micronutrients like iron and copper to reverse yellowing leaves.
The thing everyone raves about is the value. Owners consistently call it effective and long-lasting. The recommended standard feed rate is 1 teaspoon (half a capful) per gallon of water, so the math works out to a very low cost per feeding. It also works on non-jasmine plants — one buyer revived a struggling potted lime tree with it. The bloom boost is real too; another owner said it filled their porch with that signature jasmine fragrance.
The catch is that the exact NPK ratio is not published on the label, so you are trusting the brand’s proprietary blend rather than a transparent formula. For most owners, the results speak for themselves.
Best value offer: 96 gallons per bottle means this is the most economical option for anyone with multiple plants or a large outdoor trellis.
Unclear ingredients: The NPK ratio is not listed, so if you are a precise feeder who tracks every part per million, you might prefer the Perfect Plants 9-3-6.
Top cost saver: you have several jasmine plants (or other houseplants) and want a single bottle to last the whole growing season.
Verify contents: you want to know the exact nitrogen-phosphorus-potassium numbers before you pour.
3. Leaves and Soul Professional Jasmine Fertilizer 3-1-2 Concentrate
The fast-absorbing rescue formula that resurrects struggling plants in days.
This is the most popular option in the lineup by sheer volume — it has been rated over 3,500 times, making it the crowd favorite. The 3-1-2 NPK ratio is balanced. It leans slightly higher in nitrogen to encourage lush green leaves while still providing enough phosphorus for flowering. The liquid formula is fast-absorbing, meaning it moves quickly into the root zone rather than sitting on the soil surface like some granular feeds.
Owners mention seeing improvement within days. One gardenia plant arrived with curled, yellow leaves — after repotting and applying this fertilizer as directed, the plant improved noticeably and showed no recurrence of the yellowing after over a week. Another owner said it “resurrected my tree.” The formula is made in the USA by Leaves and Soul, and the brand backs it with a money-back guarantee.
Not every plant responds with heavy flowering. A few owners noted the plants grew lush and green but did not produce abundant blooms as shown in the marketing photos. This is common with a 3-1-2 ratio — it prioritizes overall plant health over maximum flower production.
Professional blend
- Fast-absorbing liquid feeds roots immediately
- Works for both jasmine and gardenia (same family of acid-loving plants)
- Money-back guarantee shows brand confidence
Watch application
- Some customers note lush growth but fewer blooms than expected
- At 8 oz, it runs out faster than the 16 oz or 32 oz options
For serious growers: you are nursing a struggling or newly bought jasmine and want a gentle, fast-acting formula that prioritizes root and leaf health.
Needs caution: your jasmine is already healthy and you want a phosphorus-heavy formula specifically designed to max out flower production.
4. TPS Nutrients Jasmine Fertilizer 32 oz
The big-bottle lifeline that pulled dying jasmine plants back to health.
At 32 fluid ounces, this is the largest bottle in the roundup — four times the volume of the 8-ounce concentrates. It is made by TPS Nutrients and is designed to support jasmine and flowering vines specifically. The size makes it the right choice for someone with a significant plant collection or a large outdoor trellis, because you are not reaching for a new bottle every month. Owners confirm it is effective; one reported it “brought my jasmine back to life” and that the plants are “now all growing better” with more blooms.
The formula provides balanced nutrition for flowering plants and works in pots, on trellises, and in garden beds. Another owner said it works immediately, calling it a must for jasmine plants. The brand makes it in the USA, and the bottle size is truly suited for frequent feeding without running dry.
Feedback is mixed — some plants did not respond to the treatment. While the effectiveness score is positive, plant growth results are mixed — some plants did not respond to the treatment. This may come down to the specific strain of jasmine or the growing conditions. For most owners, the results are clear and positive.
Large volume: 32 ounces means fewer reorders and lower cost per gallon of feed — the most economical bottle size in the list for heavy feeders.
Inconsistent effects: Some owners saw no growth improvement, so this is best suited for jasmine that is already in decent health rather than severely stressed plants.
Bulk purchase option: you have multiple jasmine plants or feed frequently and want to minimize the number of bottles you buy each season.
Results vary: you have a single small potted jasmine and do not want to store a large bottle for months.
5. TPS Nutrients Star Jasmine Fertilizer 32 oz
The bloom machine that covered a lackluster vine in fragrant flowers within days.
This is the only option on this list formulated specifically for star jasmine, a popular climbing vine used on trellises, fences, and garden beds. The 32-ounce bottle from TPS Nutrients is designed to support deep root development, lush foliage, and, critically, the sweet fragrance that makes star jasmine a favorite. Reviewers point out seeing results very quickly — one noted that after just a few days, a plant with lackluster initial flowering was “covered with those wonderful-smelling blooms.”
The formula provides nutrients to support strong vines and healthy growth, which is exactly what star jasmine needs when it is climbing a trellis or covering a fence. It is made in the USA, and the feedback is uniformly positive. Another owner said their plants looked much healthier within 2 to 3 days of application, with “lush green and bright white blooms.” Within 2 weeks, both jasmine plants produced blooms, and the owner noted that a little goes a long way.
The downside is a practical one: this is a specialty formula. If you have a different variety of jasmine, like Confederate or Arabian, a more general-purpose jasmine fertilizer like the Perfect Plants 9-3-6 might be a safer bet.
Star jasmine formula
- Specifically formulated for star jasmine’s unique growth and fragrance needs
- Shoppers say visible blooms within 2 weeks
- Large 32 oz bottle lasts a long time
Limited use
- Only suitable for star jasmine — not a universal jasmine feed
- The bottle size (32 oz) is more than most single-plant owners need
Specialized product: you specifically grow star jasmine on a trellis or fence and want a formula that boost both blooms and fragrance.
Only for star type: you grow multiple jasmine varieties — a general-purpose jasmine fertilizer will serve you better.
Understanding the Specs
NPK Ratio
The three numbers on a fertilizer label stand for Nitrogen, Phosphorus, and Potassium. Nitrogen drives leafy green growth. Phosphorus is what encourages flower buds to form and open. Potassium strengthens the plant’s overall health and resistance. For jasmine, a ratio where phosphorus is the middle or second-highest number — like 9-3-6 — is ideal for pushing out those fragrant blossoms.
Liquid Concentrate vs Ready-to-Use
Concentrated liquid fertilizers need to be mixed with water before you apply them. A teaspoon or capful per gallon is typical. This gives you control over the feeding strength and makes a small bottle last for many applications. Ready-to-use formulas cost more per gallon but are convenient for quick feedings. All the picks in this guide are concentrates, which is the most economical way to feed a jasmine plant over a full growing season.
