Knowing how to harvest garlic at the right time is crucial for maximizing your yield and enjoying delicious, homegrown garlic for months to come. At Graceland Garlic Seed, we’re passionate about empowering South African farmers with the knowledge to cultivate thriving garlic crops.
Recognizing the Signs: When is Your Garlic Ready for Harvest?
Unlike many crops that rely solely on calendar dates, harvesting garlic is more about recognizing the signs of maturity. South Africa’s diverse climate means that planting times vary across regions, but these tell-tale signs remain consistent:
- Leaf Yellowing and Browning: As your garlic plants approach maturity, you’ll notice a shift in leaf color. About 30% of the leaves will start to yellow and eventually turn brown, signaling the plant’s energy is shifting towards bulb development.
- Green Leaf Count: Aim for 4-5 primarily green leaves remaining on the plant, counting from the top leaf downwards. Each leaf serves as a protective wrapper around the bulb during storage, so ensuring an adequate number is crucial.
- Time Elapsed Since Scape Removal: If you opted to remove garlic scapes earlier in the season, your garlic will typically be ready for harvest around 3-4 weeks later.
- Test Harvest: Uncertain about your garlic’s readiness? A test harvest can offer valuable insight. Dig up a bulb or two and examine them for full clove development and separation from the hardneck.
- Scape Direction (If Intact): For those who chose to leave the scapes intact, observe their direction. A scape pointing straight up towards the sky is a strong indication that the garlic is ready for harvesting.
Variety-Specific Maturity: Remember that different garlic varieties have varying maturity periods. The popular Egyptian garlic types (white and pink) generally take around 7-8 months to reach full maturity, while the Giant variety requires about 9 months.
The Drying Down Period: How to Manage Watering Before Harvest
Garlic thrives in moist soil, but it’s crucial to avoid waterlogged conditions during harvest, as this can lead to bulb rot. As your garlic approaches maturity, gradually decrease irrigation to allow the soil to dry.
Follow these watering guidelines for optimal results:
- General Watering Rule: Aim for a consistent 25mm of water per week throughout the growing season.
- Watering During the Final Weeks: As the leaves begin to yellow and die back, continue watering lightly.
- Watering in the Days Before Harvest: To encourage proper drying, stop watering completely a few days before harvest.
The optimal drying time will depend on your soil type. Sandy soils tend to dry more quickly than heavier clay soils, so adjust your watering schedule accordingly.
Harvesting Your Garlic: A Step-by-Step Guide
Once you’ve determined that your garlic is ready for harvest, follow these steps for a successful and damage-free process:
- Loosen the Soil: Use a garden fork to carefully loosen the soil around the garlic bulbs, taking extra care not to damage the bulbs themselves.
- Pull the Bulbs: Gently pull the garlic bulbs from the ground.
- Remove Excess Dirt: Brush off any loose dirt from the roots and bulbs.
Handle with Care! Remember that damaging garlic bulbs during harvest can shorten their storage life. Treat them with care throughout the process.
Graceland Garlic’s Expert Tip: Streamlining Curing Preparation
For a more efficient curing process, we recommend taking these steps immediately after harvest:
- Trim the Bottom Leaf: Within an hour of harvesting, carefully remove the lowest green leaf from each garlic bulb. This creates a cleaner bulb for optimal curing.
- Trim the Leaf Mass: Trim the remaining leaves, leaving about 6-9 inches of stem attached to the bulb. This promotes airflow and facilitates the drying process.
