Yield responses to sulfur additions are not common in garlic, but there is active interest in determining how sulfur fertilizers may affect garlic flavor and medicinal compounds. Garlic response to micronutrients has not been reported in Minnesota. Addition of compost or other types of organic amendments will help to ensure that micronutrient supplies are adequate. Use tissue analysis to help diagnose any suspected nutrient deficiencies and fine-tune a fertilizer program. Sufficiency ranges of the most recently matured leaf sampled at initial bulbing from high yielding garlic plants are presented in Table 4.

Many garlic varieties are susceptible to yellow tips. This disorder can occur even in the presence of adequate fertility.
