When your garlic may benefit from feeding

  • When your fall-planted garlic starts sprouting in soil that needs additional nutrients for early root and leaf growth
  • As your overwintered garlic begins sending up green shoots in spring, when its need for nitrogen rises
  • While your garlic is putting on new leaves quickly, before scapes and bulb swelling signal a shift toward maturity
  • If a soil test shows your garlic bed is low in nutrients during early growth, especially in sandy or frequently watered beds

Once your garlic starts bulbing, adding extra nitrogen may be counterproductive. Base feeding on growth stage, your soil, and the product label.

How to care for garlic

Light

Full sun, at least six hours a day. Garlic grown in shade makes plenty of leaf but disappointing, undersized bulbs at harvest.

Water

About an inch of water a week while the tops are growing. Stop watering two to three weeks before harvest so your bulbs and wrappers can firm up.

Soil

Plant cloves in fall, pointed end up, two inches deep and six inches apart, in loose, well-drained soil with plenty of compost, pH 6.0 to 7.0.

Feeding

Feed Garlic Fertilizer every two weeks from the time shoots push up in early spring until your bulbs begin sizing in late spring, then stop feeding.

Pruning

Cut the curling scapes off hardneck types once they loop, about three weeks before harvest. Removing them sends more energy into your bulb, and the scapes cook well.

Harvest

Lift bulbs when the lower third of the leaves have browned, usually early to midsummer. Cure them whole in a dry, shady, airy spot for two to three weeks.

Frequently asked questions

How often should I feed garlic?

Garlic Fertilizer is meant for once-weekly feeding through the growing season, dosed by shoot height: 1 tablespoon per gallon of water while plants are under 6 inches, 2 tablespoons per gallon once they’re taller, with a hose-end sprayer set to those rates for long rows. The window that matters most is spring, from the first flush of growth until your bulbs start sizing, because that is when most of the bulb weight is added and when the potassium-leading formula does its work moving sugars from the tops into storage.

When should I stop fertilizing garlic before harvest?

Ease off once the lower leaves begin browning, typically a few weeks before harvest. At that point your garlic is transferring everything it has into your bulb and starting to cure, and late nitrogen works against you, producing soft growth and bulbs that don’t store well. Garlic Fertilizer keeps nitrogen modest at 3% for exactly that reason, but even so, the last weeks belong to the bulb rather than the feed. Most growers also stop watering in that window so the wrappers dry down properly for storage.

Why is my garlic so small?

The usual causes aren’t nutritional. Small planting cloves produce small bulbs, so always plant the biggest cloves you have. Planting too late in fall leaves too little root growth before winter, and crowded spacing, weed competition, and leaving scapes on hardneck varieties all cost bulb size. Garlic Fertilizer helps with the part nutrition controls: its potassium leads for bulb sizing, phosphorus supports the root system fall-planted garlic builds all winter, and calcium and magnesium keep the leaves working that feed your bulb. Clove size and planting timing still set the ceiling.

Should I cut the scapes off my garlic?

On hardneck varieties, yes. Cut the curling flower stalk when it makes its first loop. Left on, your garlic spends energy on a seed head instead of your bulb, and removing scapes typically produces noticeably larger garlic; it’s the same reason Garlic Fertilizer is built potassium-forward rather than nitrogen-heavy, to send resources down into storage rather than up into growth. Scapes are also excellent food, so nothing is wasted. Softneck varieties usually don’t produce scapes, so there’s nothing to cut.

When do I plant and harvest garlic?

Plant in fall, four to six weeks before your ground freezes, so roots establish before winter; spring planting works in mild climates but usually yields smaller bulbs. That root-building period is why Garlic Fertilizer carries 3.6% phosphate, and feeding weekly from spring green-up supports the sizing that follows. Harvest the following summer when roughly the lower third to half of the leaves have browned but several remain green. Pulling too late means split wrappers and poor storage; too early means undersized bulbs.

When will I see results?

Top growth responds within 1–2 weeks, since all of the nitrogen in Garlic Fertilizer is nitrate, absorbed directly by the roots without waiting on soil microbes. Bulb results arrive at harvest, because garlic sizes underground where you can’t see it: consistent weekly feeding from spring green-up through sizing is what shows up as bigger heads in summer, along with more and thicker wrappers from leaves kept green by magnesium. Fall-planted garlic fed through its first spring shows the clearest difference.
