Liquid garden fertilizer for beds, borders, and containers. Complete, fast-acting nutrition supports vegetables, flowers, and other outdoor plants through the active growing season.
How to Use Garden Fertilizer
| Method | Amount | How Often |
|---|---|---|
| Watering can — plants under 12" | 1 Tbs (15mL) per gallon of water | Feed once weekly through the growing season |
| Watering can — plants over 12" | 2 Tbs (30mL) per gallon of water | Feed once weekly through the growing season |
| Hose end sprayer | Set dial to the above feed rates | Feed once weekly through the growing season |
| Leaf misting (optional) | 1 tsp per quart (32 oz) of water | Spray on leaves every 1-2 weeks |
Mix into your normal watering — no separate feeding routine needed. Dose by plant size rather than by crop: 1 Tbs per gallon for anything under 12", 2 Tbs for taller plants, so one mixed bed can be fed in a pass or two.
What's Inside
A 3.6-3-5.1 ratio for a bed doing several jobs at once. Potassium leads at 5.1% because most garden output is fruit, roots, or flowers — it moves sugars into tomatoes, peppers, and squash and drives sizing in carrots and onions. Nitrogen at 3.6%, all of it nitrate nitrogen — absorbed directly by roots, fast-acting with low burn risk — supports the leaf canopy every crop runs on, and carries greens and herbs without pushing fruiting plants into all-foliage mode. Phosphate at 3% feeds flowering and root establishment, the two things that determine whether a plant produces at all.
Beyond NPK: sea kelp (Ascophyllum nodosum) for natural growth compounds, plus calcium at an unusually high 2.1% and 0.75% magnesium, with iron, manganese, zinc, boron, and copper. Calcium and magnesium are the two working gardens run short of first — calcium builds the cell walls behind firm fruit and crisp leaves, and magnesium drives the chlorophyll production that fades to yellowing between the veins on heavy feeders mid-season.
Made For
Mixed home gardens — tomatoes, peppers, cucumbers, squash, beans, lettuce and greens, carrots and onions, herbs, and flower borders — in raised beds, in-ground rows, containers, and grow bags where one fertilizer has to serve everything.
Problems It Solves
- Mixed beds where some plants produce and others stall
- Gardens that start strong and fade by midsummer
- Small fruit and undersized root crops
- Yellowing between the veins on heavy feeders
FAQs
How often should I fertilize my garden?
Feed once weekly through the growing season, dosing by plant size: 1 Tbs (15mL) per gallon of water for plants under 12", 2 Tbs (30mL) per gallon for anything taller. A hose end sprayer set to those rates covers beds quickly, and optional leaf misting is 1 tsp per quart every 1-2 weeks. Weekly at a moderate rate suits gardens better than occasional heavy feeding.
Can one fertilizer really work for my whole garden?
For a mixed home garden, yes — the potassium-forward balance suits fruiting crops, root crops, and flowers, while 3.6% nitrogen carries greens and herbs without overdoing it. The size-based dosing is what makes it practical: a lettuce and a caged tomato get different amounts from the same bottle. Acid-lovers like blueberries are the main exception; they need a formula built for low pH.
How is this different from 10-10-10 garden fertilizer?
Different strength and different balance. A 10-10-10 is a concentrate with equal thirds — more nutrient per ounce, dosed by area. This runs lower and potassium-forward, dosed by plant size and applied weekly, which suits gardeners who water regularly and want steady feeding with wide margin for error. It also carries calcium, magnesium, and a fuller micronutrient set that the 10-10-10 doesn't.
Is it safe for vegetables I'm going to eat?
Yes — it supplies the same minerals crops draw from any garden soil. Follow the label rate, avoid contact with skin and eyes when mixing, and wash produce before eating as you normally would. If you use the optional leaf misting, apply it earlier in the growth cycle rather than right before harvest so rinsing is simple. Not for human or animal consumption from the bottle.
Why do my tomatoes get black spots on the bottom?
That's blossom-end rot, and it's a watering problem more than a fertilizer one. Calcium can't reach developing fruit when soil moisture swings between soaked and bone dry — the plant may have plenty of calcium available and still show it. Water consistently and mulch to even out moisture. This formula's 2.1% calcium supports supply, but consistent watering is what actually delivers it.
When will I see results?
All the nitrogen is nitrate, absorbed directly by roots, so it starts working with the first watering — expect deeper green and faster growth within 1-2 weeks. The results that matter in a garden take longer: better fruit set, sizing, and sustained production build over 3-5 weeks of weekly feeding, with the biggest difference showing in midsummer when unfed gardens typically start to fade.
