Allium sativum 'Spanish Roja'
vegetableSpanish Roja is the gold-standard rocambole hardneck garlic, grown in North America since at least the late 1800s. The bulbs carry a light purple tint on white wrappers with reddish-brown clove wrappers, hold 8 to 12 cloves per head, and deliver true rich spicy garlic flavor with a touch of sweetness. The hardneck class also produces edible scapes in early summer.

When to Fertilize
Side-dress in early spring when shoots emerge through mulch
Fertilizer
Balanced 10-10-10 or fish emulsion at 1 cup per 10 ft of row
Plant individual cloves in mid-autumn (3 to 6 weeks before the ground freezes) so cloves can vernalize over winter to form proper bulbs. Set cloves 2 inches deep, point up, 6 inches apart in rows 12 inches apart. Mulch heavily with straw after planting. Cut off the curling flower stalk (scape) in early summer to direct energy into the bulb; the scapes are excellent in stir-fries and pesto. Harvest when the lower 4 to 6 leaves yellow, typically in July.

Rotate alliums out of the bed for 3 years; use floating row cover at planting
Plant only certified disease-free cloves; never replant in a bed where white rot has appeared
Cover the bed with floating row cover from planting through mid-spring; remove and destroy infested foliage
Encourage minute pirate bugs and lacewings; spray with insecticidal soap if populations build
Spanish Roja is ready when the lower 4 to 6 leaves turn brown, typically late June through July depending on region. Loosen the soil with a digging fork and lift the bulbs gently (do not pull). Brush off loose soil and cure in a shaded airy spot for 3 to 4 weeks until the necks are dry and the wrappers paper-like. Tie in bundles and hang, or store in mesh bags at 50 to 60F (as a rocambole hardneck its stiff neck does not braid); Spanish Roja typically keeps 4 to 6 months.
