There’s more to harvesting and drying sunflowers than many professional growers realize. How soon you decide to harvest them will depend largely on energy costs, temperatures, and whether you prefer them to dry naturally. Ideally, your sunflowers won’t be exposed to insects and diseases, and the temperature will be warm enough to allow them to dry on the stem. However, those circumstances are rare. In reality, most crops will be vulnerable to some level of pests and diseases. And depending upon where you live, the temperature can cause your sunflowers to freeze.

In this article, I’ll explain some of the benefits of harvesting your sunflowers early. I’ll also describe how they’re dried and why the moisture in the air can affect your crops.

Benefits Of Harvesting Early

With energy expenses escalating, you might think that allowing your sunflowers to dry naturally is a good idea. But, there are plenty of reasons why you should consider harvesting them early. First, if the temperature is close to freezing during the evenings, your sunflower crops are not actually drying. The moisture is being sealed inside. But, even if you’re not growing your sunflowers in freezing temperatures, there are still many advantages to an early harvest.

For example, the weather can often be harsh for sunflowers. Rain and strong winds can pummel your crops and prevent them from drying properly. Also, keep in mind that the longer you allow your crops to stay outside, the more vulnerable they’ll be to insects, birds, and other pests. What’s more, they’re more susceptible to mildew, mold, and diseases.

Sunflowers also have to cope with weeds, which can become a problem if they’re not managed. You can use chemicals to control them, but their effectiveness is often limited, depending upon the weather and soil. If you own a high-power dryer that can output high temperatures, consider an early harvest to dry them yourself.

Temperature And Moisture

There are many places where the air has increased capacity to hold moisture during the harvest season (for example, South and North Dakota). When this is the case, your crops will dry more quickly. Sunflowers, because of their ability to take advantage of past crops’ residual fertility, can be especially resilient in this type of weather. And the higher the temperature, the more capacity for moisture the air has. In that case, you might be able to allow your sunflowers to dry on the stem a little longer. Of course, you’ll still need to be vigilant about protecting them from critters, insects, and weeds.

Harvesting Your Sunflowers

Years ago, growers harvested their sunflowers when the backs of the heads began to turn brown. However, many crops today come from hybrids and should actually be harvested when the heads are still yellow.

When your crops have a seed moisture of about 35%, you should consider harvesting them. You can actually wait until the moisture level is approximately 12%, but you’ll run the risk of a fire in your combine. This is another benefit of an early harvest. The damper the seeds, the less likely a combine fire will occur. Plus, damp seeds are less likely to break apart while threshing. When the seed moisture is around 10%, there’s far more breakage.

Even though letting your sunflowers dry naturally tends to cost less and be lower maintenance, it’s no longer always the best choice. Today, the combines and high-temperature dryers we use allow us to harvest early and thereby further protect our crops from insects, disease and bad weather.

For many gardeners, the garden actually begins in January when the first seed catalog arrives in the mailbox. While the cold wind howls outside, we retire to a cozy chair and leaf through the catalog, carefully notating which varieties of lettuce and tomatoes to try and wishing we had the space to plant each and every flower so artfully displayed on its pages.

But have you ever wondered where your great-grandparents acquired the seeds for their gardens, before there were seed catalogs and fancy garden centers?

They saved seeds for the next year from their own gardens!

Saving seeds from your own flowers or vegetables is a wonderful way to fully experience the cycle of plant growth. It’s also much less expensive than buying seeds each spring, and seeds saved from your plants will be well suited to the peculiarities of your own garden’s growing conditions. Not only that, it’s also quite a simple process.

Save seeds only from vigorous, healthy plants. Some plant diseases may be harbored in the seed where it will then be passed on to the next generation of plants. So don’t save seeds from a plant that is obviously diseased or has struggled all season. Collect seeds from the plants that have the characteristics you desire, such as height, hardiness, early or late ripening, flavor or vigor.

It is not recommended to save seeds from hybrid plants. Hybrids are the result of crossing two genetically different parent plants, both of which have been severely inbred to concentrate the desirable characteristics. The first generation, referred to as an F1 hybrid, is superior to the parents. But succeeding generations of plants grown from seed saved from an F1 plant tend to randomly revert to the characteristics of the original inbred ancestor plants.

Plants that are not hybrids are referred to as open pollinated. Many seed catalogs will identify which of their seeds are hybrids or open pollinated. If you intend to save your own seed, always start with open pollinated seeds. Some of these may also be identified as heirloom seeds. These heirloom varieties have been passed down for generations, often saved within one family for many years before becoming available to the general public.

Cross pollination is another concern for the seed-saving gardener. Cross pollination often results in seeds which have a different genetic makeup than that of the parent plant. Pumpkins, squash and small gourds may cross pollinate with each other, resulting in seeds that will grow to produce rather picturesque fruit. Sweet corn will cross pollinate with field corn or popcorn, and your 6-inch marigolds will cross with your neighbor’s 18-inch pompon marigolds. However, crossing will only occur within a species. Cucumbers won’t cross with squash, and cosmos won’t cross with pansies.

To avoid cross pollination, keep two varieties of the same species separated by as much space as possible. Some species, such as corn, are wind-pollinated and the pollen can travel great distances. These plants must be pollinated by hand and kept isolated from other varieties of their species. This can be done with corn, for example, by tying a small paper bag over selected ears before the silk emerges, then once the silk has appeared it is hand pollinated with pollen from the same plant or its healthy neighbors.

Seeds should be collected on a dry, sunny day. Frost doesn’t hurt most seed as long as the seed remains dry. Vegetables such as cucumbers, peppers and tomatoes should be allowed to become slightly overripe before their seeds are collected. Flower seeds and vegetable seed such as lettuce should be collected after the seedheads have become dry, but don’t wait too long, as many will shatter, meaning they’ll be dropped from the seedpod or seedhead if they remain on the plant too long.

Cucumber, squash and tomato seeds need an additional step before they are ready for storage. First the seeds must be separated from the pulp, then dried. Scoop the seeds from these vegetables, pulp and all. Place the whole mess in a container of water and give it a good stir, then let it settle a bit. The pulp will rise to the top while the seeds will sink to the bottom. Carefully pour off the pulp, and repeat the process until most of the pulp has been poured off. Then strain out the seeds and set them on newspapers to dry.

Seeds should go into storage as dry as possible. Give all seed a post-harvest drying period of at least a week, just to be sure they’re dry. Spread them out on a paper plate or newspapers in a warm area out of the sun while they dry.

It’s very important to keep the seed dry during storage. Store your dry seeds in tightly sealed jars, metal film containers, or old vitamin bottles. To save space, smaller quantities of several varieties of seeds can be stored in separate envelopes inside a jar. A cool, but never freezing, garage, closed-off spare room or cool basement can all be good places for storing seeds. Or simply keep your sealed jars of seeds in the refrigerator. Temperatures between 32 and 41 degrees Fahrenheit are ideal.

Be sure to label your jars and envelopes so when spring comes around again you’ll know which flower seeds and vegetable seeds you’re planting, and include the date the seeds were collected. Some seeds will remain viable for several years, but most will grow best if planted right away the following spring.

Try saving some vegetable or flower seeds from your garden this year and grow them next season. This endless cycle can allow you to realize the endless joy of gardening through all the seasons and all the stages of a plant’s life.
