Frequently Asked Questions

How do I prevent and treat white rot in Allium sativum (garlic)?

White rot (Sclerotium cepivorum) causes yellowing, wilting, and often a white fungal growth with rotting roots near the soil line. Remove and discard infected plants, then avoid planting garlic/onions in the same spot for 5–7 years because the fungus can persist in soil. If you have had it before, plant into well-drained beds and mulch lightly to keep soil from staying constantly wet around the bulbs.

How can I tell when Northern White garlic (Allium sativum) is ready to harvest?

Harvest when the lower leaves have yellowed and dried while the top 3–4 leaves still look green, usually around 210 days from planting in typical conditions. Check bulbs by gently lifting one—ready bulbs should have fully formed cloves with tight, papery skins. Don’t wait until all leaves are brown, because bulbs can split and store less well.
