When your vegetables may benefit from feeding

When your vegetable bed's soil test calls for nitrogen, phosphate, and potash together

When leafy vegetables are actively growing and the soil's documented nutrient supply is too low

When newly established vegetable rows have rooted and your soil fertility plan calls for balanced feeding

When a previously heavily cropped raised bed has been retested and needs all three primary nutrients before the next crop

Don't add 10-10-10 automatically to every vegetable bed. Excess nitrogen can push leaves over fruit, and unnecessary phosphorus can accumulate; use soil results and the bottle's labeled rates.

What's inside

A 10-10-10 ratio sized for how vegetables actually grow — in phases. Nitrogen at 10% powers the early leaf-building phase, split evenly between 5% nitrate nitrogen, the form roots absorb directly, and 5% ammoniacal nitrogen, which soil holds and converts over days for steady feeding between applications. Then the balance pays off at flowering: 10% phosphate drives blossom and root development, and 10% potassium moves sugars into ripening tomatoes, peppers and squash — the phase where nitrogen-heavy feeds go wrong.

Beyond NPK: sea kelp (Ascophyllum nodosum) for natural growth compounds, plus 1% sulfur with iron, manganese and copper. Iron and manganese are the two a vegetable bed runs short of first — both drive chlorophyll production, and hard-working crops draw them down fast, so the shortage shows as yellowing between green veins on new growth right when plants are loading fruit.

Frequently asked questions

How often should I fertilize my vegetables?

10-10-10 for Vegetables is a balanced liquid feed, equal parts nitrogen, phosphorus and potassium, for a bed that’s producing leaves, roots and fruit at the same time. Feed every week or two through spring and summer, then every four to eight weeks in fall and winter if anything is still in the ground, at 1 to 2 ounces per gallon of water.

When in the season should I start feeding?

Once transplants have settled and started putting on new growth, or once direct-sown seedlings are up and growing. Before that the roots aren’t taking much up. From there feed every week or two straight through the productive season, and keep going while the bed is still cropping; the schedule stretches to every four to eight weeks in fall and winter for anything overwintering.

Does it work the same in containers and raised beds as in the ground?

Same rate, 1 to 2 ounces per gallon, but containers and raised beds need it more often than open ground does, because every watering carries nutrients out through the drainage. In-ground rows hold more between feeds. Mix by area rather than per plant — one ounce covers about 50 square feet — and water it in as part of a normal watering.

Is 10-10-10 good for tomatoes?

Yes, as part of a vegetable bed. 10-10-10 for Vegetables is formulated for vegetables generally, and its balanced ratio feeds tomatoes, peppers, cucumbers and greens together without favoring one. If the bed is mostly tomatoes, we also make a dedicated tomato feed.

Can I use it on vegetables I’m going to eat?

Yes. It’s made for vegetable plants you’re going to harvest. Apply it to the soil at the directed rate, water it in, and harvest as you normally would.

Will this burn my plants?

10-10-10 for Vegetables is a dilute liquid feed, and dilution is what matters here. Fertilizer burn happens when concentrated salts sit against the roots: too much product in too little water, or granules piled at the base of a plant. Mixed at 1 to 2 ounces per gallon and applied every week or two in season, the nutrients arrive in solution at a strength the roots take up as they water. Keep to that mix and water it in as part of a normal watering.
