How to Use Herbs and Leafy Greens Plant Food
| Method | Amount | How Often |
|---|---|---|
| Watering can (spring & summer) | 1 tsp per quart (32 oz) of water | Apply every 1-2 weeks |
| Watering can (fall & winter) | Same dilution | Apply every 2-4 weeks |
| Leaf misting (optional) | 1/2 tsp per pint (16 oz) of water | Spray on leaves every 1-2 weeks |
Mix into your normal watering — no separate feeding routine needed.
What's Inside
A 3-1-2 ratio built for plants you grow for their leaves. Nitrogen leads at 3%, with 2.2% of it as nitrate nitrogen — the form roots absorb directly, so it works fast with low burn risk. That matters for herbs and greens you're cutting from continuously: every harvest removes leaf tissue, and the plant needs readily available nitrogen to rebuild it. Phosphate stays low at 1% since you're not after flowers or fruit, and 2% potash keeps stems sturdy and helps plants regulate water in containers that dry out between waterings.
Beyond NPK: sea kelp (Ascophyllum nodosum) for natural growth compounds, plus 1% calcium and 0.5% magnesium, with iron, manganese, zinc, copper, and boron. Iron and magnesium are the two potted herbs run short of first — both sit at the center of chlorophyll production, so a deficiency shows up as pale leaves or yellowing between the veins while the plant is still alive and growing.
Made For
Basil, parsley, cilantro, mint, rosemary, thyme, oregano, sage, chives, and dill, plus leafy greens like lettuce, spinach, kale, and arugula — in kitchen windowsill pots, indoor herb gardens, containers, and raised beds.
Problems It Solves
- Pale or yellowing leaves on basil, mint, or parsley
- Slow regrowth after harvesting or cutting herbs back
- Thin, sparse plants instead of full, bushy growth
- Potted herbs and greens that stall out after a few weeks
FAQs
How often should I feed herbs and leafy greens?
Add 1 tsp per quart (32 oz) of water and apply every 1-2 weeks in spring and summer, dropping to every 2-4 weeks in fall and winter. You can also mist leaves with 1/2 tsp per pint (16 oz) of water every 1-2 weeks as an optional supplement. Mix it into your normal watering — herbs in containers benefit from the steady, light feeding this schedule provides.
Is this safe to use on herbs I'm going to eat?
Yes — this is a plant nutrient made for edible herbs and greens, and the minerals in it are the same ones plants take up from any garden soil. Follow the label dilution, avoid contact with skin and eyes when mixing, and rinse harvested leaves before eating as you normally would. It is not for direct human or animal consumption from the bottle.
Why is my basil flowering or bolting?
Bolting is triggered by heat and long days, not by nutrition — fertilizer won't stop it and isn't causing it. Pinch off flower spikes as soon as they appear and harvest regularly to keep the plant in leaf-production mode. Steady feeding helps basil regrow quickly after pinching, but once summer heat sets in, some bolting is normal for the plant.
Why are my herbs leggy and stretched out?
Legginess is almost always a light problem, not a feeding problem. Herbs stretching toward a window need brighter conditions — most want direct or bright indirect light. Fertilizer can't compensate for low light, and pushing nitrogen on a light-starved plant just makes the stretching worse. Move the plant to more light, pinch it back, and feeding will then support full, bushy regrowth.
Will fertilizer make my herbs taste better?
Steady, moderate feeding keeps herbs producing the healthy new growth where flavor is strongest — old, starved leaves taste flat. But more fertilizer isn't more flavor: overfeeding pushes fast, watery growth that can actually dilute the concentrated oils that make basil or rosemary taste like themselves. Stick to the label rate and harvest often; that combination does more for flavor than heavier feeding.
When will I see results?
Nitrate nitrogen is absorbed directly by the roots, so it starts working with the first watering. Expect visibly greener leaves within 1-2 weeks and noticeably faster regrowth after harvesting within 2-4 weeks of regular feeding. Fast growers like basil and mint respond quickest; woody herbs like rosemary and thyme grow slower by nature and take longer to show the difference.
