Common Garlic Varieties
Popular cultivars to look for at your local nursery or seed supplier.
Rocambole (Spanish Roja)
Classic hardneck with rich, complex flavor; easy to peel and widely loved by chefs.
Porcelain (Music)
Large hardneck cloves with bold, lingering heat; one of the most productive varieties.
Softneck (Inchelium Red)
Excellent keeper lasting 9–12 months; mild flavor makes it ideal for braiding.
Elephant Garlic
Technically a leek relative; mild, subtle flavor in very large cloves — great roasted whole.
Purple Stripe (Metechi)
Beautiful purple-streaked cloves with rich, complex flavor; stores well into winter.
Common Garlic Problems
What to watch for — and how to fix it before it spreads.
Pests
Rasp leaf surfaces leaving silver streaking; reduce photosynthesis and yield.
Apply spinosad; use reflective mulch; water consistently to avoid plant stress.
Microscopic mites tunnel into cloves, causing rot and poor germination.
Inspect and discard soft cloves at planting; dip seed garlic in 30-second hot water treatment (130°F).
Diseases
Fluffy white growth at the base of bulbs with tiny black sclerotia; soil-persisting fungus.
Do not plant garlic (or onions/leeks) in affected beds for 20+ years; there is no cure.
White elliptical spots on leaves that coalesce in cool, wet weather; defoliation reduces bulb size.
Apply copper fungicide; improve airflow; harvest promptly when scapes fall.
Common Mistakes
Garlic needs cold vernalization to form multiple cloves; spring-planted garlic produces a single undivided bulb.
Plant hardneck garlic in fall (4–6 weeks before ground freezes) for harvest the following July.
Scapes left on the plant divert energy from bulb development, reducing final size by up to 30%.
Cut scapes when they make one curl (curl has just completed); eat scapes fresh or freeze them.
Too-early garlic has undeveloped wrappers; too-late bulbs burst open and store poorly.
Harvest when 5–6 bottom leaves have turned brown; each leaf = one wrapper layer on the bulb.
🌾 Seed Saving Guide
🪴 Vegetative propagationPropagate vegetatively, not by seed
Garlic is propagated by planting individual cloves — save the largest cloves from your harvest for replanting.
Select the largest, healthiest bulbs from your harvest as your "seed garlic" for the next growing season.
