Do walnut seeds need stratification?

Do walnuts need to be cold stratified?

Common plants that require stratification include apples, sloes, hawthorns, plums and acorns, but also smaller seed from herbaceous perennials such as aquilegia, lavender, sage, sedums, perennial sweet peas, wild rose and hops. One way to break this dormancy is to leave it up to nature.

What happens if you don't cold stratify seeds?
Stratification is the process of giving your seeds a period of 'cold' to prepare them for better germination. If you dont stratify seeds, they can still germinate but the rate is often much lower and they can actually take 2 or 3 times longer to germinate. A refrigerator is all you need.
Can walnuts be stored at room temperature?

Pros and Cons to Stratification
There are pros and cons to doing about anything. Let’s start with the cons of cold stratifying seeds. It is time consuming to refrigerate or cold water stratify.

The 3 Methods to Cold Stratify Seeds
There are different methods you can do to stratify your seeds: outside directly into the soil, cold water stratification, and refrigerator stratification. Any of these will work, and you will figure out which you prefer to use to start your seeds.
Step 1
Gather some walnuts as soon as they have fallen off a tree and remove the husks. If you have a walnut tree in your area, you can pick them up for free.
Step 2
Place the walnuts into a bucket of water. This will soften the hull and it will be easier to peel the husk by hand. You can also remove the husks by placing in a hand-operated corn sheller. Another machine that you can use to remove the husks is to place them into a small cement mixer.
Step 3
Wash the walnuts. Fill a basin with water and then add the walnuts. If any of the walnuts float, discard them as they will not germinate well.
Step 4
Dig a hole 4 to 5 inches deep in the area where you want the walnut tree to grow. It is a good idea to plant at least six walnut seeds at the same time. Plant each walnut seed 2 to 3 inches apart, planting in a cluster. You can also dig one big hole so you can plant all the walnut seeds at the same time. Then cover the black walnut seeds with soil.
Step 5
Cover the area with a 3-inch layer of mulch. You can use straw or leaves to cover the area. This will protect the black walnut seeds during the freezing and thawing cycles.
Step 6
Mark the area with sticks or rocks to you know where your walnut seeds were planted.
Step 7
Remove the mulch in late winter or very early spring. Be sure to leave your markers in place. This will prevent you from mowing over the young black walnut trees.
