Katterman Hardneck Porcelain Garlic - Organic

Hardy in Zones

3–8

Porcelain Garlic

This hardneck type produces 3–6 very large cloves with tight porcelain-white skins. Excellent storage. Huge cloves are wonderful in the kitchen and perfect for pesto-making or baking whole.

Scapes form arches, curls and loose coils, and develop hundreds of tiny grain-sized bulbils. 20–40 cloves per pound. Zone 3-8.

Hardneck vs. Softneck

Hardneck garlic (Allium sativum subsp. ophioscorodon) has a hard stalk in the center of the bulb, and (the vast majority of the time) only one ring of cloves. Plant grows an edible scape, a tall leafless stalk with a flowerbud-like top. Tops are too rigid to braid but can be tied in attractive bundles and hung.

For best bulb size, cut off the scape before it uncurls. One of our favorite midsummer tasks is clipping the scapes and enjoying them grilled, stir-fried, pickled, or in pesto! If you leave the scapes on, the garlic bulb will likely be smaller, but you’ll get a ‘flowerhead’ full of little bulbils, which you can plant if so inspired.

Hardnecks are closer to wild garlic, and varieties present a range of characteristics and complex flavor profiles. Very cold hardy.

Softneck garlic (Allium sativum subsp. sativum) produces multiple rings of cloves and a soft braidable top. Softneck types have mostly lost the ability to produce a stalk with flowering parts—but sometimes they produce extra “cloves” (technically bulbils) in the stem. Growers like softneck varieties for their extra-long shelf life in cold storage. More forgiving of hotter climates than hardneck varieties.

Growing Garlic: Give it Space, Feed it and Weed it!

In late fall, 3–4 weeks before the ground freezes, prepare a nitrogen-rich well-groomed seedbed. Garlic grows best in well-drained soils that are high in organic matter with a neutral pH. Consider getting a soil test to help you apply nutrients optimally. To make things easy for yourself, prepare beds with our 3G Greener Garlic Grower. Also consider our 5G Grow Great Garlic Kit.

Break up the bulb, leaving clove skins intact, and plant cloves 6–8" apart, pointed side up, with the base about 3" deep. Mulch with about 4" of straw, leaves or hay.

In spring, move the mulch to free any struggling plants, then replace it to keep moisture even and to help suppress weeds. Consider supplementing with a quick-release nitrogen source like blood meal or feather meal. Check under the mulch occasionally to make sure soil stays moist throughout the season; well-drained or sandy soils may need watering, while heavier clay soils might need none at all.

In midsummer, the curly scapes of hardnecks will begin to unfurl and stand up. We suggest cutting them back before they straighten up (unless you want to work with bulbils) to ensure bigger bulbs.

In mid-late summer, allow the soil to dry somewhat about a week before harvest. Check bulb growth when the bottom leaves are yellow and 5–6 upper leaves are still green, late July to early August for us in central Maine. Harvest bulbs before cloves begin to separate. Use a garden fork to loosen the soil and lift gently.

Tie and hang to cure in a well-ventilated place, protected from sun and rain, until dry. Do not field-cure.

To store, trim roots, trim tops to within 1" of the bulb, rub off loose skins and any dried dirt, and store in a cool dry place.

Replant your best garlic in late fall for next year’s crop. The cycle continues!

Seed Garlic

The bulb size, the skin color, the flavor, and the size and number of cloves are partly determined by genetics and ecotype, and partly by soil, climate, moisture and seasonal growing conditions. We base our variety descriptions on industry standards, as well as reports from farmers, our garlic suppliers and our own experiences. Your harvests may differ slightly. Garlic is a dynamic crop that, while maintaining some varietal consistency, evolves every generation.

Our size standard for a seed garlic bulb is 2" diameter, but we reserve the right to ship smaller garlic in difficult crop years. Fedco requires every lot of garlic to test negative for garlic bloat nematode, white rot and botrytis neck and bulb rot.

Items from our perennial plants warehouse will ship around late September through October. Bulbs can be planted successfully up until your ground freezes.

Note to Alaska and far north customers: We cannot guarantee an early shipment, so please plan accordingly and order early.

We cannot accommodate specific ship date requests or guarantee your order will arrive by a certain day.
