When To Plant Garlic In Arkansas

If you want a successful garlic harvest next summer, knowing when to plant garlic in Arkansas is the most important step. Getting the timing right gives your cloves the best chance to establish roots before winter, leading to bigger, better bulbs. This guide will walk you through the perfect planting schedule, variety selection, and simple steps for success in The Natural State.

Planting garlic in the fall might seem counterintuitive, but it’s the secret to a great crop. Garlic needs a period of cold weather to properly develop its bulbs, a process called vernalization. By planting in autumn, you mimic its natural growth cycle. The cloves settle in, send down roots, and are ready to explode with growth as soon as spring warmth arrives.

The ideal planting window across Arkansas is from mid-October through mid-November. This timing is crucial. You want to get the cloves in the ground after the heat of summer has passed but well before the ground freezes solid.

The goal is to allow the garlic to establish a robust root system—without sending up significant green shoots above ground. If you plant too early, warm soil can trigger top growth that gets damaged by winter frost. If you plant to late, the cloves won’t have enough time to root and may heave out of the ground or simply rot.

Adjusting for Your Arkansas Region

Arkansas’s climate varies, so fine-tune your timing based on where you live:

Northwest & Ozark Highlands: Aim for early to mid-October. Frosts come earlier here, so getting cloves in a bit sooner is wise.
Central Arkansas (River Valley & Metro areas): The sweet spot is typically late October to early November.
Southern & Southeastern Arkansas: You can plant from early to late November, as winters are milder and soil stays warmer longer.

A good rule of thumb is to plant after the first light frost but about 4-6 weeks before your ground typically freezes. The soil should be cool, around 50°F, which is perfect for root development.

Choosing the Right Garlic for Arkansas

Not all garlic is the same. There are two main types, and your choice impacts flavor and harvest time.

Softneck Garlic: This is the type you commonly see braided in stores. It prefers milder winters, stores exceptionally well (often up to a year), and produces lots of smaller cloves. It’s an excellent choice for central and southern Arkansas gardeners. Varieties like ‘California Early’ and ‘Silverwhite’ perform well.
Hardneck Garlic: Hardnecks are known for their complex, rich flavors and large, easy-to-peel cloves. They produce a edible central stalk called a scape in spring. They are more cold-hardy, making them ideal for northwest Arkansas. However, their storage life is shorter, usually 4-6 months. Popular varieties include ‘German Extra Hardy’ and ‘Music’.

Always source your planting garlic from a reputable nursery, seed company, or local farm. Do not plant garlic from the grocery store, as it is often treated to prevent sprouting and may carry soil-borne diseases.

Preparing Your Planting Site

Garlic thrives in full sun and well-draining soil. It will not do well in heavy, soggy clay that stays wet all winter.

Choose a Sunny Spot: Select a garden bed that gets at least 6-8 hours of direct sunlight daily.
Amend the Soil: Work in several inches of compost or well-rotted manure a few weeks before planting. Garlic is a heavy feeder. You can also add a balanced organic fertilizer.
Ensure Good Drainage: If your soil is heavy, consider building a raised bed. Good drainage is non-negotiable to prevent bulb rot.

Step-by-Step Planting Guide

Break the Bulb: Carefully separate the garlic bulb into individual cloves just before planting. Keep the papery skin on each clove—it acts as a protective layer.
Plant Cloves Pointy-End Up: This is critical. The pointy tip is where the shoot emerges. Plant each clove about 2 inches deep.
Spacing is Key: Space cloves 4-6 inches apart within the row. Space rows about 12 inches apart. This gives the bulbs plenty of room to size up.
Cover and Mulch: Cover the cloves with soil and water them in well. Then, apply a 4-6 inch layer of loose mulch like straw, shredded leaves, or pine needles. This mulch insulates the soil, prevents weeds, and protects against temperature swings.

Seasonal Care for Your Garlic

Once planted, garlic requires minimal but attentive care through the seasons.

Fall & Winter: After mulching, you can mostly forget about it. The cloves will be busy growing roots underground.
Spring: As shoots emerge, keep the area weeded. In early spring, you can side-dress with a nitrogen-rich fertilizer like blood meal. When hardneck varieties send up their curly scapes in May, snap them off. This directs the plant’s energy back into bulbing.
Watering: Garlic needs consistent moisture, especially during bulbing in spring. Aim for about 1 inch of water per week if rainfall is insufficient. A crucial tip is to stop watering about two weeks before your planned harvest date to let the bulbs cure in the ground.

Harvesting and Curing Your Bounty

Knowing when to harvest is as important as knowing when to plant. In Arkansas, most garlic is ready from late May through June.

Watch for these signs: the lower leaves start to turn brown and dry out, while the top 5-6 leaves may still be green. Do not wait for all the leaves to die back. Gently dig up a test bulb; it should be well-formed with defined cloves.

Use a garden fork to gently loosen the soil and lift the bulbs.
Brush off excess soil, but do not wash the bulbs.
Curing: This step is essential for long storage. Hang bunches of garlic or lay them out in a single layer in a warm, dry, well-ventilated area out of direct sun for 3-4 weeks. The outer skins will become papery.
Once cured, trim the roots and cut back the stalks (unless you plan to braid softnecks). Store in a cool, dark, dry place.

Troubleshooting Common Problems

Even with perfect timing, issues can arise. Here’s how to handle them:

Garlic Not Sprouting in Spring: This usually means the cloves rotted over winter, often due to poor drainage or planting too deeply. Improve your site for next season.
Small Bulbs: Causes include planting too late, insufficient sunlight, overcrowding, or lack of nutrients during the growing season.
Pests: Onion thrips and nematodes can be a problem. Practice crop rotation—don’t plant garlic in the same spot where onions or garlic grew the previous year. This is one of the best defenses.
Diseases: White rot and downy mildew can occur. Again, rotation is key. Always plant healthy, disease-free cloves and remove any infected plants immediately.

FAQ: Planting Garlic in Arkansas

Can I plant garlic in the spring in Arkansas?

You can, but the results are often disappointing. Spring-planted garlic misses the crucial cold period, usually resulting in very small, single-clove bulbs called “rounds.” For full-sized, multi-clove bulbs, fall planting is strongly recommended.

What is the best mulch for garlic?

Straw is a classic choice because it’s light and insulating. Shredded leaves or pine needles also work very well. Avoid using heavy mulch like whole leaves or grass clippings, which can mat down and create a soggy environment.

How do I know if my garlic is ready to harvest?

Watch the leaves. When about half of the lower leaves have turned brown and died back, it’s time to check. Gently dig up a bulb. If the cloves are swollen and fill out the skin, harvest time has arrived.

Can I use store-bought garlic to plant?

It’s not recommended. Grocery store garlic is often from varieties not suited to our climate and may be treated with sprout inhibitors. It can also carry diseases into your garden soil. Invest in certified seed garlic for the best results.

Should I fertilize my garlic?

Yes. Garlic benefits from fertile soil. Add compost at planting and then apply a nitrogen-rich fertilizer in early spring as growth resumes. This feeds the developing bulbs and supports strong leaf growth.

By following this schedule and these tips, you’ll set your garlic up for a productive season. The simple act of planting at the right moment in fall leads to the rewarding experience of pulling up plump, aromatic bulbs next summer. Remember, the key is to get those cloves in the ground during that cool autumn window, let them sleep through winter, and watch them thrive come spring.
