Ah, fall—the season of cozy sweaters, pumpkin spice lattes, and, for all you green thumbs out there, the promise of a bountiful garden next year. While the trees shed their leaves, we gardeners are busy collecting seeds for the future. Join me on this journey as we dive into the exciting world of harvesting seeds in the fall, a practice that connects us to nature’s rhythm and guarantees a vibrant garden in the seasons to come.

The Art of Seed Harvesting:
Step 1: Timing is Everything
Fall is the perfect time to start harvesting seeds. As the days grow shorter and cooler, plants begin to focus their energy on producing seeds. The key is to keep an eye out for those seed pods and heads that are dry and brown. This indicates that they are ready for harvest.
Step 2: Gather Your Tools
Before you embark on your seed-harvesting adventure, gather a few essential tools:
- Small bags or envelopes: For storing and labeling your seeds. I always use paper envelopes to avoid any moisture buildup.
- Scissors or pruners: To snip seed heads or pods.
- A marker: To label your seed packets.
- A notebook: To jot down important details about your seeds.
Choosing the Right Seeds:
Not all seeds are created equal, and some are easier to harvest than others. Here are a few favorites that are perfect for beginners:

- Sunflowers: Their large, distinctive heads are easy to spot and collect.
- Marigolds: These vibrant flowers produce seeds that resemble tiny arrowheads.
- Nasturtiums: Their seed pods are easy to gather and add a peppery punch to salads. These are some of my favorite flowers in the garden!
- Basil: Wait for basil to bolt and produce seeds for next year’s pesto.
- Dill: these seeds smell amazing and are easy to harvest ones the dill is done producing and dry
- Cilantro: cilantro seeds are also super easy to harvest once the plant is dry
Cross-pollination and What You Need To Know:
Gardening isn’t just about planting seeds and watching them grow; it’s also about understanding the intricate dance of nature that happens right before our eyes. One of the most captivating aspects of gardening is cross-pollination, a natural process where plants exchange genetic material.
What is Cross-Pollination?
Cross-pollination occurs when pollen from one plant is transferred to the stigma of another plant, typically of the same species but a different variety. This process is essential for genetic diversity, leading to healthier and more adaptable plant populations. While some plants are self-pollinators, meaning they can fertilize themselves, many rely on pollinators like bees, butterflies, and even the wind to carry pollen from one flower to another.
Why Cross-Pollination Matters:
- Biodiversity: Cross-pollination increases genetic diversity, making plants more resilient to pests, diseases, and environmental changes.
- Hybridization: Cross-pollination can result in hybrid plants with unique characteristics, such as different colors, sizes, or flavors.
- Adaptation: Plants that cross-pollinate have a better chance of adapting to changing environmental conditions, ensuring their survival over time.
Common Cross-Pollinators in the Garden:
- Tomatoes: While many tomato varieties are self-pollinating, they can also cross-pollinate if grown in proximity. This can lead to exciting new tomato hybrids.
- Squash: Different varieties of summer and winter squash can cross-pollinate, resulting in intriguing squashes with unexpected shapes and colors.
- Zucchini and Cucumbers: These garden staples can cross-pollinate since they belong to the same family. You might end up with a cucumber that tastes slightly like zucchini or vice versa.
- Lettuce: Lettuce plants can cross-pollinate, leading to variations in leaf color, texture, and shape.
Preventing Unwanted Cross-Pollination:
While cross-pollination can lead to exciting surprises, it may not always be desirable. If you want to maintain the purity of a particular plant variety, follow these tips:
- Isolation: Plant different varieties of the same species as far apart as possible to reduce the chances of cross-pollination.
- Hand Pollination: For precise control, use a small paintbrush to transfer pollen from one flower to another. This is particularly useful for plants like squash.
- Timing: Plant varieties with different flowering times to avoid overlapping pollination periods.
Cross-pollination can definitely impact your next season’s crop, so for many (like myself) that plant a lot of different vegetables in close proximity – I buy new seeds each season that run this risk so I know I am going to get exactly what I want. But, it can be fun to experiement sometimes, too!
The Harvesting Process:

Once you’ve identified your target seeds, it’s time to start the harvesting process. Follow these general steps:
- Cut the Seed Heads or Pods: Use your scissors or pruners to carefully snip the seed heads or pods from the plant. Make sure to do this on a dry, sunny day when the plants are free of moisture.
- Drying: Place the seed heads or pods in a warm, dry location for about a week to ensure they’re completely dry. This prevents mold and rot during storage.
- Extraction: Once your seeds are dry, gently remove them from their seed heads or pods. Be patient; this can be a bit time-consuming but is incredibly rewarding.
- Labeling: Don’t forget to label your seed packets with the plant’s name, the date of harvest, and any other relevant information, such as flower color or special care instructions.

Here are a few seed saving items I use and love:
- A binder – I use this to hold and organize my seeds
- Postcard Sleeves – these fit your seed packets (your own or purchased) perfectly
- Seeds! – You’ll need plenty of seeds for your garden, especially those you aren’t able to harvest yourself or are trying out for the first time.
The Joy of Seed Saving:
Harvesting seeds in the fall isn’t just about saving money on next year’s garden; it’s a way to connect with the natural world and develop a deeper appreciation for your plants. Plus, there’s something truly magical about planting seeds you’ve collected yourself. It’s like tucking a piece of the past season into the ground, nurturing it, and watching it bloom anew.
As we bid farewell to another summer, remember that fall is not just about saying goodbye—it’s also about preparing for the future. Harvesting seeds in the fall is a delightful and rewarding practice that allows you to play a role in the circle of life in your garden. So, grab your pruners, embrace the crisp autumn air, and get ready to sow the seeds of future beauty and bounty in your garden. Happy harvesting!
