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 often should I water Allium sativum during the main growing season, and what soil moisture level should I aim for?
From spring growth through bulb sizing, water deeply about 1–2 times per week only when the top 1 inch of soil is dry, keeping the root zone consistently moist but not waterlogged. Aim for steady moisture because garlic forms larger bulbs when soil doesn’t swing between very dry and saturated. Stop routine watering about 3–4 weeks before harvest so wrappers can dry down and bulbs cure properly.
