Lavender rewards gardeners who respect its low-maintenance nature, yet the right nutrition still makes the difference between woody stems and a season loaded with fragrant spikes. Choosing the wrong feed can push soft leafy growth that won’t flower, or scorch the roots on this Mediterranean native that prefers lean, alkaline-leaning soil. This shortlist gathers eight fertilizers that fit real lavender care, from organic blends built for blooms to a formula designed specifically for the plant itself.
The Shortlist At A Glance
Jobe’s Organics Granular All Purpose Fertilizer, 4 lbs Bag
Miracle-Gro Performance Organics Blooms Plant Nutrition Granules, 2.5 lb
Perfect Plants Liquid Jasmine Fertilizer, 8 oz Concentrated Bloom Food
Miracle-Gro Organic Plant Food, 32 fl. oz.
Schultz Spf48270 Slow-Release Bloom Fertilizer, 3.5 Lbs
True Organic All Purpose Plant Food, 4lb Bag
True Organic Annuals & Perennials Food, 4lb Bag
TPS Nutrients Lavender Fertilizer, 8 oz Liquid Plant Food
A Closer Look At Each Pick
For gardeners who want a single bag that handles lavender alongside the rest of the bed, Jobe’s Organics Granular All Purpose Fertilizer is the easy answer. The granules are designed to reduce wasteful runoff and mess, which matters when you’re working around Mediterranean herbs that resent soggy soil. At 4 lbs, the bag covers a small grouping of established lavenders with room to spare, and the organic formula works for vegetables and ornamentals too, so nothing goes unused if you only grow a few lavender plants.
Beginners who feel unsure about nutrient ratios will appreciate that this pick sidesteps the math entirely. You scatter, you water, you move on. Lavender growers in mixed cottage beds get the most from it, since the same scoop feeds the surrounding roses, salvias, and tomatoes without missing a beat.
What It Does Well
- Granular format makes application fast, even across a full perennial border.
- Organic formulation supports soil life, which benefits the lean, well-drained conditions lavender prefers.
- Designed to limit runoff and odors, so it stays pleasant to handle in tight spaces.
- One bag covers vegetables, flowers, shrubs, and trees, which reduces clutter in the shed.
Points To Keep In Mind
- Lavender needs only light feeding, so the full bag may sit longer than expected, and granules can clump if stored in humidity.
- Because it’s a general formula, it doesn’t push bloom intensity the way a bloom-specific blend does.
Built With In Mind
Gardeners running mixed ornamental and edible beds who want one dependable organic granular for everything, including lavender.
Look Elsewhere When
You’re growing lavender in containers and want the precise dosing a liquid offers, in which case the TPS Nutrients Lavender Fertilizer below fits the bill.
If your priority is flower count rather than green growth, this blend tilts the nutrient ratio toward blooms. The natural and organic ingredients target flowering plants in ground beds and containers alike, and the granules wake plants up quickly when watered in. Compared to the all-purpose Jobe’s bag above, this one trades versatility for sharper bloom performance.
It’s a sensible pick for gardeners who run lavender alongside geraniums, petunias, or other heavy bloomers in the same border. You apply it dry, give it a soak, and the bed starts working toward more spikes within a short window.
Standout Benefits
- Bloom-focused formulation channels energy into flower production rather than foliage.
- Works in both garden soil and patio containers, useful for lavender in pots.
- Granular format means no mixing, measuring, or extra bottles cluttering the shed.
Honest Caveats
- The 2.5 lb bag runs out faster than the larger Jobe’s option, so heavy feeders will need backups.
- Lavender is a light feeder by nature, so over-applying this bloom-heavy blend can backfire with floppy stems.
Right Fit For
Growers running flower-heavy borders who want a granular bloom booster that handles lavender alongside petunias and geraniums.
A Better Fit Elsewhere
You mostly grow lavender and a few herbs and want something milder, in which case Jobe’s Organics Granular All Purpose Fertilizer is the calmer option.
Pot-grown lavender behaves differently than in-ground plantings, and Perfect Plants Liquid Jasmine Fertilizer gives you the precise dose containers demand. The concentrated 8 oz bottle stretches across many watering cans, and the formula targets continuous flowering rather than leafy growth. It’s formulated for jasmine but the nutrient profile lines up well with the way lavender wants to be fed.
You measure, mix, and pour at watering time, which fits a routine where every pot gets attention anyway. Apartment growers with a sunlit balcony and a handful of lavender plants will find the bottle lasts a full growing season.
The Upside
- Liquid format delivers nutrients quickly, useful when potted lavender looks hungry midseason.
- Concentrated bottle means a little goes a long way, lowering replacement frequency.
- Bloom-targeted ratio supports spike production on container plants.
Trade-Offs
- Mixing and measuring takes more effort than scattering granules, and it’s easy to overdo on small pots.
- It’s formulated for jasmine, so you’re matching profiles rather than buying a lavender-specific blend.
Best Suited To
Balcony and patio gardeners raising lavender in containers who prefer liquid feeding and already water by hand.
Consider Something Else When
You want a formula built specifically for lavender rather than adapted from jasmine nutrition, in which case the TPS Nutrients Lavender Fertilizer later in this list is the closer match.
For gardeners who prefer liquid feeding across the board, this 32 fl. oz. bottle covers a lot of territory. It’s made predominantly from plant-based ingredients and works on indoor houseplants, outdoor containers, and in-ground beds, which means a single bottle handles the lavender on the patio and the herbs on the kitchen windowsill. Compared to the smaller Perfect Plants concentrate, this one trades bloom specificity for general versatility.
You dilute, pour, and the soil takes the nutrients up almost immediately. Gardeners who already keep a watering can in hand will barely notice the extra step.
Advantages To Know
- Liquid format acts fast, so hungry lavender responds within days rather than weeks.
- Large 32 fl. oz. bottle covers many watering sessions across multiple plants.
- Plant-based formula appeals to organic-focused growers.
- One bottle works for indoor and outdoor use, which simplifies storage.
Softer Spots
- It’s a general-purpose liquid, not a bloom booster, so flower-heavy beds may need a partner product.
- Liquid plant food requires consistent mixing and application, and skipping weeks can leave pots hungry.
Quick Reference
Who It Suits Best
Growers who already water by hand and want one liquid that handles lavender, houseplants, and patio pots without juggling multiple bottles.
Not Your Match When
You want a granular bloom booster for an in-ground lavender hedge, in which case Miracle-Gro Performance Organics Blooms Granules is the sharper choice.
Busy gardeners who forget midseason feedings will appreciate that Schultz Spf48270 Slow-Release Bloom Fertilizer keeps working in the background. The 12-24-12 ratio (that’s nitrogen, phosphorus, and potassium in that order) leans toward bloom support, and the slow-release format meters nutrients gradually. You apply once, and the soil does the rest for weeks.
It’s the calmest entry in this list for anyone who treats lavender as set-and-forget. The 3.5 lb bag covers a substantial hedge or several smaller beds without forcing constant reordering.
The Good Stuff
- Slow-release format reduces how often you need to reapply.
- Bloom-leaning 12-24-12 ratio supports flower production over leafy growth.
- Granular format is easy to scatter around established plants.
Things To Consider
- Slow-release granules can sit on top of heavy clay without breaking down, so a light scratch-in helps.
- It’s not an organic formula, which matters for gardeners following strict organic routines.
Made For
Growers who want a single spring application that quietly feeds lavender through the bloom cycle without constant reapplication.
Swap It Out When
You prefer organic-only inputs and want a similar low-effort approach, in which case True Organic All Purpose Plant Food offers that profile in granular form.
True Organic All Purpose Plant Food brings an organic-first approach to gardens that mix lavender with food crops. The 5-4-5 nutrient profile (again, nitrogen, phosphorus, potassium) with mostly slow-release nitrogen keeps growth steady rather than forcing a sudden surge, which suits lavender’s preference for measured feeding. One 4 lb bag covers around 87 square feet, so a small hedge or front border finishes in a single application window.
Vegetable gardeners who tuck lavender into the corners for pollinators will appreciate having one organic bag for everything. The slow-release behavior also forgives a missed watering here and there.
Notable Upsides
- Mostly slow-release nitrogen steadies growth, which matches lavender’s preference for gentle feeding.
- Organic blend suits gardeners running edible beds alongside ornamentals.
- Covers a meaningful area per bag, reducing how often you reorder.
Worth Noting
- The general-purpose profile is less bloom-targeted than a dedicated bloom formula.
- Coverage assumes standard spread rates, so dense plantings can eat through the bag faster.
Feature Card
Who Should Grab It
Edible-garden growers who want one organic granular that handles lavender, herbs, and vegetables without switching products.
Reach For A Different Pick When
You want a bloom-targeted organic blend for cutting-style flower beds, in which case True Organic Annuals & Perennials Food is the sharper sibling on this list.
The companion to the all-purpose organic blend above, True Organic Annuals & Perennials Food focuses on flowering plants. It’s designed to push bloom performance and foliage health across the season, and a 4 lb bag covers around 70 square feet of bed. For lavender, that translates to roughly a small hedge or a generous mixed perennial border.
Growers who treat lavender as a flowering ornamental rather than a herb will appreciate the targeted profile. It’s organic-leaning, gentle on Mediterranean natives, and supportive of the surrounding salvias, echinaceas, and rudbeckias that often share the bed.
Everyday Wins
- Bloom-focused organic formula complements lavender’s flowering habit.
- Plays well with other sun-loving perennials in the same bed.
- Coverage area lines up with typical suburban border plantings.
Some Limits To Know
- Single-purpose profile means you need a separate feed for vegetables or lawn areas.
- Bloom push can produce floppy lavender stems if applied too heavily, so measured rates matter.
The Right Fit
Cut-flower and ornamental-border gardeners who run lavender alongside echinacea, salvia, and other sun-loving bloomers.
Another Choice May Suit
You’re feeding both edible crops and ornamentals and want one bag for everything, in which case True Organic All Purpose Plant Food earlier in this list covers both ends.
The only product on this list designed specifically for lavender, TPS Nutrients Lavender Fertilizer removes the guesswork from matching nutrient ratios to plant type. The 8 oz liquid bottle targets root development and bloom consistency, which addresses the two most common lavender complaints. For a single-species bed or a serious hobbyist collection, that specificity is the whole point.
It mixes into your regular watering routine, so container and in-ground plantings both benefit. Lavender enthusiasts with several cultivars, including the finicky ‘Hidcote’ and ‘Munstead’ varieties, will find the targeted formula worth the smaller bottle size.
Positive Takeaways
- Species-specific formulation removes the trial-and-error of matching general feeds to lavender.
- Liquid format reaches roots quickly, supporting establishment on newer plantings.
- Compact 8 oz bottle stores neatly alongside other small garden essentials.
Practical Considerations
- Lavender-specific only, so other garden plants will need their own feed.
- The smaller bottle runs out faster on larger plantings, so you may need backups midseason.
Whose Shelf It Belongs On

Matching Lavender Fertilizers To Your Garden
Lavender asks for less than most flowering shrubs, which is part of its charm, but the wrong feed still ruins a season. The biggest decisions happen before you open the bag.
Picking Between Granular And Liquid
Granular products like Jobe’s Organics or the True Organic blends release nutrients slowly and tolerate irregular watering, which suits busy gardeners and in-ground beds. Liquid feeds such as the TPS Nutrients lavender bottle and the Miracle-Gro Organic liquid act faster and let you adjust dose by pot, which suits container growing and gardeners who already water by hand. Lavender responds to either format, so the right choice usually comes down to your routine rather than the plant’s preference.
Reading The NPK Ratio
The three numbers on a fertilizer label stand for nitrogen (N), phosphorus (P), and potassium (K), always in that order. Nitrogen drives leaf growth, phosphorus supports roots and blooms, and potassium strengthens overall plant health. Lavender thrives on balanced or bloom-leaning ratios, and heavy nitrogen feeds often produce floppy stems with few flowers. Schultz’s 12-24-12 bloom blend leans strongly toward phosphorus, while the True Organic formulas stay closer to a gentle 5-4-5 balance.
Organic Versus Conventional
Organic fertilizers feed the soil along with the plant, building microbial life that helps lavender’s roots access what they need. Conventional formulas feed the plant more directly, which can be useful for quick corrections but adds up over time. Gardeners raising lavender near food crops often prefer organic inputs for that reason, while growers chasing fast color recovery sometimes lean toward conventional bloom boosters.
Key Considerations Across These Picks
Common Shopping Slip Ups
The most frequent mistake with lavender is overfeeding, especially with bloom-heavy blends that look gentle but still push more growth than the plant can handle. Another slip is ignoring soil pH, because lavender prefers a slightly alkaline, lean medium, and even the best fertilizer underperforms in acidic, rich soil. Shoppers also tend to skip the second-half-of-summer pause, feeding when the plant is already slowing down rather than letting it harden off for winter.
Where The Extra Money Goes
Higher-tier picks like the lavender-specific TPS Nutrients bottle cost more per ounce, but the price reflects a tailored formula rather than a generic blend. You pay for precision: a product engineered around one plant’s actual preferences instead of an all-purpose mix that mostly works. For growers running a small lavender hedge or a serious collection, that specificity saves the trial-and-error of finding the right general feed, which often costs more in wasted bags and mediocre blooms.
Frequently Asked Questions
How Often Should You Fertilize Lavender?
Lavender typically needs only one light feeding in early spring as new growth emerges, with a possible second light application after the first flush of blooms if the plant looks tired. Heavy or frequent feeding produces soft, floppy growth that struggles to flower.
Can You Use All-Purpose Fertilizer On Lavender?
Yes, an all-purpose organic blend like Jobe’s Organics or True Organic works well at reduced rates, since lavender prefers gentle nutrition. The key is to apply lightly rather than at full strength, especially with nitrogen-heavy formulas.
Is Liquid Or Granular Better For Lavender?
Both formats work, and the right pick depends on your routine. Granular options like Schultz’s slow-release bloom fertilizer suit in-ground beds and busy gardeners, while liquid feeds like the TPS Nutrients lavender bottle suit containers and hands-on watering schedules.
What NPK Ratio Works Best For Lavender?
Balanced or bloom-leaning ratios perform best, with a mild preference for higher phosphorus numbers during the flowering cycle. Schultz’s 12-24-12 bloom blend is one example, while the True Organic blends stay closer to a gentle 5-4-5 balance for lighter feeding.
Should You Skip Fertilizer In Summer?
A late-summer pause is often wise, since lavender begins hardening off for cooler weather and excess nutrients push tender growth that winter can damage. One spring feeding, possibly followed by a light post-bloom boost, covers most gardens.
Closing Remarks
Lavender rewards restraint more than effort, and the right fertilizer is the one that matches your soil, your watering habits, and how much lavender you’re really growing. A small hedge of established plants wants little more than a gentle spring feeding, while a pot collection or new planting benefits from closer attention. Pick the format that fits your routine, keep the rates measured, and let the plant do what it does best: bloom, scent the air, and ask for very little in return.
