How To Prepare Your Garden For A Great Garlic Harvest

Fall is just around the corner and it is time to start thinking about planting seed garlic. Planting large individual garlic cloves will produce larger bulbs, but another consideration should be the soil. Preparing soil for garlic properly is also key to a successful garlic crop the following summer. Watch our video Selecting and Planting Garlic for more information on planting and growing garlic.

Practice Crop Rotation

  • Practicing smart crop rotation should be followed.

  • Make sure you are not planting seed garlic (also onions, shallots or leeks) in the same area every year.

  • Also you should not plant seed garlic next to an area where you are planning to plant beans or peas. Garlic and other alliums seem to stunt the growth of these vegetables.

How to Prepare Soil for Garlic

The best soil for growing seed garlic is sandy loam that is well-drained. If you your soil is clay and tends to have drainage problems, you can plant in raised rows, raised beds (at least 12 inches deep) or even large pots. It is best to get your soil amended with compost and fertilizer before planting.

Step 1: Add Organic Matter 

Hands holding soil.

This can be done naturally by using summer cover crops. You can grow a summer cover crop that gets worked back into the soil weeks before the garlic is planted.

  • Some great summer soil building mixes are the Peaceful Valley Summer Soil Builder Mix, which is a mix of buckwheat and cowpeas. This requires more pre-planning since it will take about 6-7 weeks for maturation and then a few more weeks for it to break down in the soil.
  • Buckwheat is a great plant for quick growth (finished in only 30-45 days) and will actually pull insoluble phosphorus out of the soil which will be released into a plant-available form when it breaks down. If you don't want to grow a cover crop or don't have time, work in quality compost or composted manure to increase the organic matter.
  • If you don't have the space or time to plant a cover crop, you can always add compost to the planting area for your seed garlic.

Step 2: Fertilizing

When planting seed garlic in the fall, avoid giving it a high nitrogen fertilizer. The idea is to get the roots established before the plant gets hit by cold temperatures of winter. It is not ideal to have a significant amount of above ground growth before spring, unless you live in an area with milder winters. If this happens, the top growth can be damaged by severe winter temperatures.

Since seed garlic need a good supply of phosphorus for root development, you can work in fertilizers that has higher levels of phosphorus and potassium such as the following:

  • Bone meal

  • Soft rock phosphate

  • Seabird or bat guano that are high phosphorus

  • Peaceful Valley Organics Bloom and Bud 0-10-10

Come spring when the seed garlic plants are starting to put out leaves, top dress with fertilizer with a higher amount of nitrogen, like the Bio-Fish, All Purpose, Phyta-Grow Leafy Green Special Fertilizer, blood meal, feather meal, high nitrogen guanos, or fish meal.

Mulching

Mulching is especially important if the seed garlic is planted where cold winters and harsh winters are normal and the ground freezes. Cover with a thick layer of straw to protect the garlic throughout the winter; about 4-6" in very cold regions.

In milder climates a thinner layer is just fine. In the summer the mulch will help conserve water, cut down on weed growth and will help even out fluctuations in soil temperature.

Pest and Disease Management

Common Pests Affecting Garlic and Preventative Measures for Pest Control

Pest and disease management is crucial when planting garlic in the fall to ensure healthy growth and robust bulb formation. Common pests affecting garlic include aphids, thrips, and nematodes, which can damage foliage and stunt plant growth.

To prevent infestations, practice crop rotation, maintain weed-free garlic beds, and inspect plants regularly for signs of pests. Additionally, ensuring well-drained soil and avoiding waterlogged conditions helps mitigate fungal diseases such as white rot and rust, which can impact garlic quality and yield.

Applying organic mulch and using companion planting strategies can also aid in pest control while promoting overall garlic health.

Identifying and Treating Common Garlic Diseases

When planting garlic in the fall, it's important to be vigilant against common garlic diseases that can affect bulb development and overall plant health. Diseases such as white rot, rust, and fusarium wilt are potential threats, manifesting as yellowing leaves, stunted growth, or discolored bulbs.

To mitigate these issues, ensure well-drained soil and practice crop rotation to prevent disease buildup. Applying fungicidal treatments early in the season and maintaining soil moist can also help protect garlic plants from diseases. Additionally, using raised beds can improve drainage and air circulation, further reducing the risk of disease.

When you plant your garlic, selecting larger cloves can lead to more robust plants and fragrant bulbs at harvest time. Regular monitoring and care will promote a successful harvest of healthy bulbs, allowing you to enjoy the rewards of your gardening efforts.

Cover Crops and Crop Rotation

Advantages of Using Cover Crops and Best Cover Crops for Garlic Beds

Using cover crops in garlic beds offers several benefits for successful garlic cultivation. Cover crops help improve soil structure and fertility by adding organic matter and fixing nitrogen, essential for robust garlic bulb development.

They also prevent soil erosion, suppress weeds, and provide a natural mulch layer that regulates soil temperature and moisture levels, especially during cold winters and early spring. Recommended cover crops for garlic beds include legumes like clover and vetch, as well as grasses such as rye and oats, which contribute to soil health and support garlic's nutrient needs throughout its growing season.

Integrating cover crops into your gardening practices ensures healthier garlic plants and larger bulb yields.

Implementing Crop Rotation Strategies

Implementing crop rotation strategies is crucial for maintaining soil health and optimizing garlic bulb production. By rotating garlic with other plant families each growing season, you can minimize soil-borne diseases, pests, and nutrient depletion specific to garlic. This approach also acts as a natural pest repellent, reducing the likelihood of infestations.

For instance, planting legumes like beans or peas after garlic enriches the soil with nitrogen, benefiting subsequent crops. This practice helps break pest and disease cycles, including plant diseases that can affect infected plants, ensuring healthier garlic plants and sustainable garden yields over time. Incorporating crop rotation into your gardening routine supports overall soil fertility and enhances the success of your garlic harvests.
