Do Tomato Seeds Have to be Dried Before Planting?

Tomatoes are a popular crop grown by many gardeners. Growing tomatoes from seed can be a rewarding way to obtain a fresh and healthy yield of tomatoes. But, do tomato seeds have to be dried before planting? The answer is yes, but there are some exceptions.

Why Dry Tomato Seeds?

Drying tomato seeds is a necessary step in preparing them for planting. The moisture in the fresh seeds can cause them to sprout prematurely or become moldy, which can prevent germination. Drying can also allow for easier storage and transport of the seeds.

How to Dry Tomato Seeds?

There are several ways to dry tomato seeds, but the most straightforward method is to allow them to air-dry. Once the seeds are removed from the tomato, place them in a single layer on a labeled, non-stick surface, such as a glass plate, ceramic, or paper towel. Place them in a dry environment, out of direct sunlight, and with proper airflow, for about a week. Stir them daily to ensure even drying. A seed is considered adequately dried when it snaps in half when bent.

Exceptions to Drying Tomato Seeds

Although drying tomato seeds is generally recommended, there are a few exceptions to consider. Some gardeners preserve the gel sack, which surrounds the seeds. The gel sack contains enzymes that can inhibit germination, so it must be removed before planting. To do so, simply place the seeds and the gel sack in a jar with warm water and let it sit for about two days. Then, stir and remove the floating gel and unsinkable seeds, which are viable seeds. Plant them right away, without drying. Additionally, some heirloom tomatoes have seeds with a high germination rate directly from the fruit. These seeds may be sown directly without drying.

In Conclusion

Drying tomato seeds is an essential step for most gardeners to obtain viable, healthy seeds for planting. However, some exceptions must be considered, such as saving the gel sack or using heirloom varieties with viable seeds directly from the fruit. By understanding the different methods, gardeners can ensure they have the right seeds for their tomato crop.
