Growing the BIGGEST Garlic? 10 Common Garlic Growing Mistakes To Avoid

1. Planting the Wrong Variety

Choosing garlic varieties not suited to your climate can result in small bulbs or poor yields. Hardneck garlic thrives in colder regions, while softneck garlic performs better in warmer climates. Researching and selecting the right type is the first step to success.

2. Planting Too Late in the Season

Garlic needs time to establish roots before winter frost sets in. Planting too late can stunt growth and lead to undersized bulbs. For most regions, mid-fall is the ideal planting time to ensure a robust harvest.

3. Using Store-Bought Garlic

Store-bought garlic is often treated with chemicals to prevent sprouting, making it unsuitable for planting. Instead, buy seed garlic from a trusted supplier to guarantee healthy, untreated bulbs designed for growing.

4. Planting Cloves Too Close Together

Crowded garlic competes for nutrients, water, and sunlight, resulting in smaller bulbs. Space cloves 6 inches apart in rows about a foot apart to give each bulb ample room to grow. Proper spacing leads to larger, healthier harvests.

5. Poor Soil Preparation

Garlic thrives in nutrient-rich, well-draining soil. Planting in compacted or nutrient-deficient soil can hinder growth. Work in compost or aged manure before planting to create the ideal environment for your crop.

6. Neglecting Mulching

Skipping mulch leaves your garlic vulnerable to weeds and temperature fluctuations. Apply a 3–4 inch layer of straw, leaves, or other organic mulch to conserve moisture, suppress weeds, and insulate bulbs during the winter.

7. Overwatering

Too much water can lead to root rot and fungal issues. Garlic prefers consistent moisture but needs well-draining soil to avoid sogginess. Water deeply but sparingly, especially as the bulbs mature.

8. Failing to Fertilize Properly

Garlic is a heavy feeder and requires adequate nutrients to grow large bulbs. Neglecting to fertilize or using the wrong type can stunt growth. Use a balanced fertilizer with high nitrogen content early in the growing season for best results.

9. Harvesting Too Early

Pulling up garlic before the leaves have started to brown can result in immature, undersized bulbs. Wait until the bottom few leaves have turned brown but the upper leaves are still green for the perfect timing.

10. Ignoring Curing and Storage

Failing to cure garlic properly after harvest can lead to mold and spoilage. Let bulbs dry in a cool, airy space for 2–3 weeks before trimming roots and storing. Proper curing ensures your hard work pays off with long-lasting, flavorful garlic.
