Garlic

210d to harvest

Siberian Garlic brings a bold, warming aroma that blooms into a rich, savory flavor—sharp at first, then beautifully mellow. Expect firm, medium-to-large bulbs with a classic hardneck personality: easy to peel cloves and a satisfyingly snappy texture that holds its character for roasting, sauces, and slow-simmered favorites. Grow Siberian Garlic for dependable, long-season performance and the kind of kitchen-ready intensity that makes every harvest feel like a triumph.

Frequently Asked Questions

What pest or disease most commonly affects Allium sativum (garlic), and how do I stop it?

Garlic most often suffers from fungal basal rot (often seen as soft, brown rot at the bottom of the bulb) and sometimes white rot. Plant only healthy, firm cloves, rotate away from all Allium crops for several years, and avoid overhead watering so the leaves and neck stay dry; if you spot rotting plants, remove them promptly to protect nearby bulbs. Ensure the soil drains well and don’t over-fertilize with nitrogen late in the season, which can make plants more prone to rot.

During the main growing phase, how often should I water Allium sativum and what soil moisture level should I aim for?

From spring growth through bulb sizing, keep soil consistently moist but not waterlogged—about 1 inch (2.5 cm) of water per week total, adjusted for rain and heat. Water deeply when the top 1–2 inches (2.5–5 cm) of soil feel dry, then let excess drain; garlic needs oxygen around the roots, so soggy soil increases rot risk. In the final 3–4 weeks before harvest, reduce watering so the bulbs can dry and cure properly.

How can I tell when Siberian garlic (Allium sativum) is ready to harvest at ~210 days?

Harvest when about half the leaves have yellowed and the lower leaves are drying, while the bulbs are still firm and well-filled. Check by gently lifting one bulb with a fork—mature cloves should feel distinct and the skins should be tight around the bulb. If the leaves are still mostly green, wait a bit longer; if the neck is collapsing and cloves are separating, you’re likely past the best harvest window.
