How To Choose The Best Fertilizer For Jasmine
Jasmine plants are heavy feeders during their growing season, but they are also sensitive to over-fertilizing. The wrong balance can push out lots of green leaves while producing zero flowers. Here are the two things that matter most.
NPK Ratio and Bloom Support
The three numbers on the bottle (nitrogen (N), phosphorus (P), potassium (K)) tell you what the plant gets. A balanced ratio like 3-1-2 or a formula higher in phosphorus helps support flower development without overwhelming the plant with nitrogen that only grows leaves. Most liquid jasmine fertilizers in the guide offer a bloom-boosting mix designed for flowering vines.
Concentrate Volume and Mixing
You can buy liquid concentrates in 8 oz to 32 oz bottles. An 8 oz bottle works for a few houseplants, but a 32 oz bottle makes up to 192 gallons of feed — a better value if you have multiple jasmine plants or an outdoor vine. Always follow the label’s mixing ratio (typically 1 teaspoon per gallon of water) to avoid burning the roots.

In‑Depth Reviews
1. HiThrive 32oz Jasmine Fertilizer
The big-bottle workhorse that feeds a whole garden without breaking the budget.
The HiThrive 32 oz bottle makes 192 gallons of feed, versus 96 gallons from the 16 oz version, so it is the clear value winner if you have multiple plants or an outdoor vine. Its nutrient-rich blend includes iron, copper, manganese, and zinc (micronutrients that reverse yellowing leaves and slow growth), and it works for Star Jasmine, Downey, Dwarf, Forest, Primrose, and more jasmine types. Users simply mix 1 teaspoon (half a capful) per gallon of water for a standard feed, or 2 teaspoons (a full capful) for plants showing nutrient deficiency.
Buyers report that their jasmine responded immediately, with more and stronger leaves and more flowers. A reviewer with eight different jasmine types noted that all of them improved daily within a week of using this food. If you only want to buy one bottle to cover every jasmine in your home and garden, this is the one.
Value champion: At 32 fl oz making 192 gallons of feed, it offers more total liquid volume than the 8 oz concentrates like the Perfect Plants or Leaves and Soul options, at 8 fl oz each.
Single caveat: It requires mixing each time — not a premixed spray, so keep a measuring spoon with your watering can.
Reach for this if… you want the biggest gallon yield per bottle and need a proven formula that handles both indoor and outdoor jasmine varieties.
Look elsewhere if… you only feed one small potted plant — the 16 oz size makes 96 gallons and may be a better fit.
2. TPS Nutrients Jasmine Fertilizer 32 oz
A premium concentrate designed for jasmine that brings struggling vines back to life fast.
TPS Nutrients formulated this specifically for jasmine and flowering vines, providing balanced nutrition that supports both growth and bloom development. At 32 fl oz, it offers the same bottle size as the HiThrive 32 oz but is positioned in a higher price tier, reflecting its targeted formulation and USA manufacturing. It is suitable for pots, trellises, and garden beds, making it a versatile option whether your jasmine climbs a fence or sits on a patio table. The mixing directions are straightforward — users dilute it with water and apply regularly.
Reviewers report very quick results — one owner noted their jasmine came back to life and produced more blooms after using this feed. Another reviewer called it a must-have for jasmine plants, saying it works immediately. However, one indoor grower mentioned that their plant grew taller without blooming as expected, suggesting that light levels also play a role in flower production. If you are growing jasmine indoors with limited sunlight, this is something to keep in mind.
Strong points
- Immediate results reported — buyers saw growth and blooms in days
- Large 32 oz bottle for extended use
- Made in USA
Considerations
- Indoor jasmine may still need strong light to flower consistently
- No prominent NPK ratio stated on the label
Best for quick recovery: If your jasmine looks weak or has stopped blooming, this liquid feed often shows results within days.
Not ideal if… your jasmine does not get enough sunlight — even the best fertilizer cannot replace light for bloom production.
3. HiThrive 16oz Jasmine Fertilizer
A smaller, budget-friendly entry into the same effective formula as the 32 oz version.
The HiThrive 16 oz bottle makes 96 gallons of feed, versus 192 gallons from the 32 oz version. It delivers the same blend of macro and micronutrients — iron, copper, manganese, and zinc — to reverse yellowing leaves and promote fragrant blooms. The mixing ratio is identical: 1 teaspoon per gallon for standard feeding, 2 teaspoons for plants showing deficiency. It covers all the same jasmine varieties, from Star Jasmine to Primrose.
Buyers confirm that it is effective and easy to use, with one reviewer noting their jasmine responded immediately, with more and stronger leaves and more flowers. Another owner appreciated the value for money, saying the instructions were simple to follow. If you only have a couple of jasmine plants and do not need a gallon-making machine, this smaller bottle saves you upfront cost while delivering the same nutrient profile.
Perfect for small collections: This is the ideal entry point if you have two or three jasmine plants and want to test the formula without committing to the larger 32 oz bottle.
The trade-off: At 16 fl oz it makes 96 gallons, which is still a lot for a single houseplant — you will have concentrate leftover for months.
Reach for this if… you feed a small number of jasmine plants and want the lowest upfront cost in the HiThrive line.
skip it if… you have a large outdoor vine or multiple plants — the 32 oz version is a better value per gallon.
4. Perfect Plants Liquid Jasmine Fertilizer 8oz
A specialized bloom formula with a high NPK ratio that targets flower production.
Perfect Plants takes a different approach than the other liquid fertilizers here — rather than a generic balanced feed, this 8 oz concentrate uses a 9-3-6 NPK formula specifically formulated for the Jasminum family of vine plants. The higher nitrogen (the first number) supports vigorous leaf growth, while the phosphorus and potassium drive bloom development and fragrance. It comes in a resealable bottle that keeps its effectiveness for months, and it is designed so that you apply only a small concentrated amount per watering. This is a premium formula at a mid-range price point.
Owners mention immediate visible results — one reviewer noted they saw results from the first time they used it on abandoned jasmine plants, with buds appearing after just one watering. Another owner noted noticeably improved leaf greenness, bloom abundance, and fragrance intensity. Compared to the HiThrive options, this is a smaller bottle (8 fl oz vs 32 fl oz) but with a more targeted NPK profile for those who want a species-specific feed rather than a general plant food.
What stands out
- Species-specific 9-3-6 NPK for Jasminum vines
- Customers note buds appearing after a single watering
- Resealable bottle that stays effective for months
What to know
- Small 8 fl oz volume — less concentrate than the 32 oz options
- Higher price per ounce than bulk bottles
Best for targeted feeding: If you want a formula built specifically for jasmine’s NPK needs and you value immediate bud production, this is your pick.
Look elsewhere if… you need a large volume of concentrate for multiple plants — the 8 oz bottle will run out faster.
5. Leaves and Soul Professional Jasmine Fertilizer 8oz
A professional 3-1-2 blend that gardeners report works across multiple plant families.
Leaves and Soul markets this as a professional jasmine fertilizer with a balanced 3-1-2 NPK formula, designed to promote strong roots, lush foliage, and vibrant blooms. At 8 fl oz it is a smaller concentrate bottle, but it is fast-absorbing (liquid mixes easily and delivers nutrients directly to roots). It is manufactured in the USA and backed by a money-back guarantee. The company recommends diluting with water, and the formula is suitable for all growth stages from young plants to mature flowering jasmine.
Interestingly, while this product targets jasmine, many buyers have reported outstanding results on other plants. One buyer mentioned it had an immediate, positive effect on newly planted gardenias, which were blossoming after just one week. Another noted it cured curled, yellow leaves on a gardenia within days. The versatility is a bonus, but if you need a jasmine-specific NPK like the 9-3-6 from Perfect Plants, this more general 3-1-2 ratio might not be as optimized. It is a solid choice for the gardener who wants one reliable liquid feed for multiple flowering plants.
Versatile performer: Reviewers point out great results on gardenias and peace lilies too — this is not just a jasmine feed.
The nuance: The 3-1-2 ratio is more balanced than bloom-specific — it supports overall plant health as much as flowers.
Reach for this if… you want a professional-grade liquid that works on jasmine and other acid-loving flowering plants like gardenias.
pass on it if… you want a jasmine-specific NPK ratio rather than a general flowering plant formula.
6. TPS Nutrients Star Jasmine Fertilizer 32 oz
A star-jasmine-specific feed from TPS that focuses on deep roots and sweet fragrance.
This is the companion product to the TPS Nutrients Jasmine Fertilizer above, but specifically formulated for Star Jasmine varieties (Trachelospermum jasminoides). It comes in the same 32 fl oz bottle and is made in the USA. The formula supports deep root development, lush foliage, and flowering, with an emphasis on enhancing the natural fragrance of star jasmine. It is suitable for trellises, fences, garden beds, and landscape use — ideal if your star jasmine is climbing a structure or covering a wall.
Shoppers say that within two weeks of using this fertilizer, their jasmine plants produced blooms. One owner reported that a little goes a long way. Another owner mentioned that an established vine showed improved health and growth after application. Compared to the standard TPS Jasmine Fertilizer, this one is more narrowly targeted at star jasmine growers. If you grow standard jasmine (Jasminum officinale) rather than star jasmine, the regular TPS Jasmine Fertilizer is the better match.
Strong points
- Specifically formulated for star jasmine vines
- Buyers report blooms in as little as two weeks
- Large 32 oz bottle with concentrated formula
Considerations
- Narrower target — not ideal for other jasmine species
- Fewer reviews available compared to the general TPS formula
Best for dedicated star jasmine growers: If your garden is full of star jasmine vines and you want a formula designed for their specific needs, this is the one.
Not for you if… you grow multiple jasmine species — the general TPS Jasmine Fertilizer or the HiThrive options cover a broader range.
Understanding the Specs
NPK Ratio
This stands for nitrogen (N) — for leaf and stem growth, phosphorus (P) — for root and flower development, and potassium (K) — for overall plant health and disease resistance. A jasmine-specific feed like the Perfect Plants 9-3-6 has a higher first number for leafy growth, while a balanced formula like the Leaves and Soul 3-1-2 is more general. Higher phosphorus (the middle number) is what actually pushes flowers to form.
Liquid Volume and Gallons Made
This tells you how much concentrated fertilizer you get in the bottle and how many gallons of diluted feed it produces. An 8 oz bottle makes fewer gallons than a 32 oz bottle — but the HiThrive 32 oz makes 192 gallons of feed, which is enough for regular watering of several plants across an entire growing season. The higher the gallons-made number, the better the value if you have many plants.
