Purived 16oz All-Purpose Liquid Plant Fertilizer - Makes 50 Gallons, for Indoor Houseplants, All-Natural, Groundwater Safe, Made in USA

I’m always wary of one-bottle, “feeds-everything” plant foods, but after a full season using the Purived fertilizer across my indoor collection and a few patio containers, I’m comfortable saying it earns a place on the shelf. It’s a straightforward, concentrated formula that prioritizes ease of use and consistent results over flashy claims—and that’s exactly what many home growers need.

What you’re getting

This is a 16 oz liquid concentrate designed to be diluted at one capful per gallon of water. At that rate, the bottle makes up to 50 gallons of nutrient solution. The concentrate is essentially odorless, which matters if you mix and water indoors. It’s labeled as groundwater-safe and carries a two-year shelf life. It’s also positioned as an all-purpose feed suitable for soil drench, foliar spraying, and both full and semi-hydroponic setups.

In practice, that scope of use checked out. I used it as a routine feed in potting mixes, as an occasional foliar spray on foliage plants, and in semi-hydro with LECA. No residue, no sour smell, and no clogging in small spray nozzles or wicking setups.

Mixing and ease of use

The “capful per gallon” direction makes this very beginner-friendly. For standard watering cans, that’s as fast and simple as it gets. The concentrate blends cleanly; no clouding or precipitate in my watering cans or glass jars. I do recommend shaking the bottle before each use—concentrates often benefit from a quick homogenize.

Two usability notes:
- If you mix smaller quantities (say, a half-gallon pitcher), the unmarked cap makes exact half-measures guessy. I ended up using a dedicated measuring spoon for more precise sub-gallon mixes.
- The bottle pours cleanly, with minimal dribble down the sides—a small but appreciated touch if you’re mixing frequently on a kitchen counter.

Performance on real plants

I tested this primarily on common houseplants: pothos, monstera, ficus (including a temperamental fiddle leaf), maidenhair fern, peperomia, and a few succulents. Outdoors, I fed potted herbs and a container lemon balm. Across the board, I saw steady improvements in leaf color and new growth rate consistent with a reliable, balanced feed.

• Foliage plants: Pothos and monstera responded quickly, pushing new leaves in the 2–4 week window after I started weekly feeding. The leaves weren’t abnormally huge or soft (a sign of overfeeding), just healthy-looking with good sheen.
• Finicky types: The fiddle leaf fig maintained consistent new growth with fewer crispy edges—always a win, though I still attribute most of that plant’s stability to proper light and watering. The fertilizer supported, rather than “fixed,” its temperament, which is what a fertilizer should do.
• Ferns and peperomia: No burn at the recommended dilution, and I liked the way the foliage held color without crisping. For ferns, I did a soil drench and used a very light foliar mist monthly.
• Succulents: I cut the dose to half-strength and reduced frequency to every 3–4 weeks. That timing helped avoid the stretched, overly lush growth that general-purpose fertilizers can trigger in succulents under indoor light.
• Flowering: In containers outside, herbs and lemon balm stayed lush and rebounded quickly after harvesting. This isn’t a bloom-boosting specialty formula, but for general vigor it did exactly what I wanted.

I didn’t see any leaf-edge burn or salt crust forming in the soil when used as directed. Still, I recommend a simple flush (plain water through the pot) every month or so, especially if your tap water is hard.

Foliar and semi-hydro use

As a foliar feed, it was easy to work with. I used a weaker dilution (about half-strength) and sprayed in the morning so leaves dried before midday light. No spotting or residue on glossy leaves, and no lingering scent. It’s not a miracle foliar—just a mild, clean feed that offers a slight bump between soil drenches.

In semi-hydro with LECA, I ran the recommended dilution in a reservoir jar for philodendron cuttings and a scindapsus. The solution stayed clear, and I didn’t see film or gunk building up on the clay balls. For longer-term semi-hydro setups with recirculation or frequent top-ups, you might want a TDS or EC meter for precision, but for simple passive setups this worked well at label strength.

Frequency and regimen

My schedule that produced good results:
- During active growth (spring/summer): once a week at full strength for most foliage plants; half-strength for succulents and sensitive varieties.
- During slower growth (fall/winter): every 2–3 weeks at half-strength, or pause entirely for plants that are truly resting.
- Foliar: once a month at half-strength, optional and plant-dependent.

This is a flexible, forgiving fertilizer. It doesn’t demand a strict program, and it won’t punish minor inconsistencies.

Value and shelf life

Cost-per-gallon is where this concentrate shines. One bottle lasted me through a season with dozens of feedings and still had room to go. The two-year shelf life is practical; you won’t feel rushed to finish it, even if you’re feeding a small collection.

Environmental and indoor friendliness

The near-zero odor makes a bigger difference than you might think—no sharp ammonia note when mixing, and no lingering smell in the room after foliar applications. The groundwater-safe positioning is reassuring, especially if you water in a sink or on a balcony where runoff is inevitable.

Where it falls short

• Precision mixing for small batches: The cap isn’t marked in milliliters, so if you’re mixing a quarter- or half-gallon, you’ll need a separate measuring spoon to avoid guessing.
• Not a specialist formula: Advanced growers who tune nutrients for specific stages (e.g., high-nitrogen vegetative vs. high-potassium bloom) will find this too general-purpose. It’s designed as a well-rounded feed, not a targeted deficiency corrector.
• Limited label detail: It’s a clean, simple product, but if you rely on granular micronutrient breakdowns for diagnosing issues like iron or magnesium deficiencies, you may still want supplemental tools or a more specialized fertilizer on hand.

None of these are dealbreakers for typical indoor gardeners, but they’re worth noting if you run a large or especially sensitive collection.

Tips for best results

• Start at half-strength on sensitive plants (ferns, calatheas, succulents) and step up as needed.
• Flush pots monthly to prevent salt buildup, especially with hard tap water.
• Foliar feed in the morning and avoid direct sun on wet leaves.
• Shake the bottle before use; concentrates can settle.
• Mix only what you’ll use in a week, label your jug, and store the concentrate sealed at room temperature.
• Pair with appropriate light and watering—fertilizer amplifies good care; it won’t compensate for poor fundamentals.

The bottom line

Purived’s all-purpose fertilizer hits the sweet spot for home growers: easy to mix, versatile across soil and semi-hydro, odorless for indoor use, and economical enough to feed regularly without hesitation. It delivered consistently healthier foliage and steady new growth in my collection without the drama of burn or residue, and it integrates smoothly into a weekly watering routine.

Recommendation: I recommend this fertilizer to indoor and patio gardeners who want a reliable, low-fuss, one-bottle solution. It’s ideal if you’re managing a mixed collection and value clean mixing, low odor, and strong cost-per-gallon. If you’re chasing highly specialized results (orchids in bloom cycles, production hydroponics, or remedying specific micronutrient deficiencies), you may prefer a more targeted lineup. For most houseplants and general-purpose feeding, though, this is a genuinely solid, set-and-forget staple.
