Step 1: Choosing the Right Time for Harvesting

Timing is crucial when it comes to harvesting nasturtium seeds. To ensure optimal seed development, it’s important to wait until the seed pods have fully matured on the plant. Harvesting too early could result in underdeveloped seeds that may not germinate successfully.

Generally, the best time to harvest nasturtium seeds is towards the end of the growing season when the plants have finished blooming, and the petals have fallen off. This is usually in late summer or early fall, depending on your location and the specific climate conditions.

To determine if the seed pods are ready for harvest, examine them closely. Mature seed pods are large, swollen, and have a hard outer shell. They may also change color, transitioning from green to yellow or brown. Avoid harvesting seed pods that are still green, as the seeds inside may not be fully developed.

Keep in mind that not all seed pods on the nasturtium plant will mature at the same time. You may need to inspect the plant regularly and harvest the pods individually as they reach maturity. It’s a good practice to mark the date of harvest on each seed pod to keep track of their age.

Once you’ve determined that the seed pods are mature, it’s time to proceed to the next step: identifying ripe nasturtium seed pods.

Step 2: Identifying Ripe Nasturtium Seed Pods

Identifying ripe nasturtium seed pods is essential to ensure that you harvest seeds at their peak maturity. Ripe seed pods are more likely to contain fully developed seeds that have a higher chance of germination.

When examining the seed pods, look for the following characteristics to determine if they are ripe:

  1. Size and shape: Ripe nasturtium seed pods are usually larger and plump compared to immature ones. They may reach a size of around 1 inch (2.5 cm) or more.
  2. Color: As the seed pods mature, they tend to change color. Depending on the variety, the colors can range from green or pale yellow to brown. Ripe pods often have a darker hue or may have started turning brown.
  3. Texture: Gently squeeze the seed pod between your fingers. If it feels firm and slightly hard, it is likely ripe. Avoid seed pods that are soft or squishy, as they may contain undeveloped seeds.
  4. Rattling sound: Shake the seed pod gently. If you hear a rattling sound, it indicates that the seeds inside have loosened from the pod’s walls and are ready for harvest.

It’s important to note that not all seed pods on a nasturtium plant will ripen at the same time. The pods may ripen sequentially, starting from the bottom of the plant and moving upward. Therefore, it’s recommended to inspect each seed pod individually to determine its ripeness.

Once you have identified ripe seed pods, you are ready to move on to the next step: harvesting the seed pods.

Step 3: Harvesting the Seed Pods

After identifying the ripe nasturtium seed pods, it’s time to harvest them from the plant. The goal is to remove the seed pods without damaging them or the plant itself.

Follow these steps to harvest nasturtium seed pods:

  1. Gather your tools: Before starting, gather a pair of clean and sharp garden scissors or pruning shears. This will make the process easier and prevent any unnecessary damage to the plant.
  2. Select the seed pods: Carefully choose the ripest and healthiest seed pods for harvesting. Remove any damaged or diseased pods to ensure the quality of the seeds.
  3. Hold the stem: Hold the stem of the seed pod firmly with one hand, ensuring you have a good grip on the pod.
  4. Cut the stem: Using your pruning shears or scissors, cut the stem just above the point where it connects to the main stem of the plant. Make a clean and precise cut to minimize any potential damage.
  5. Continue harvesting: Move along the plant and repeat the process, harvesting the desired number of seed pods. Remember to leave some pods on the plant for natural reseeding or to enjoy the blooms.

It’s important to handle the seed pods with care, as rough handling or squeezing can cause damage and affect the viability of the seeds inside. By following these steps, you can ensure a successful harvest without harming the plant.

Once you have harvested the seed pods, it’s time to move on to the next step: opening the seed pods to extract the seeds.

Step 4: Opening the Seed Pods

Now that you have successfully harvested the ripe nasturtium seed pods, it’s time to open them to access the seeds inside. Opening the seed pods can be done easily with just a little bit of gentle pressure.

Follow these steps to open the nasturtium seed pods:

  1. Prepare a clean work surface: Find a clean and well-lit area to work on. Spread out a sheet of newspaper or a clean cloth to catch any seeds that may be released during the process.
  2. Hold the seed pod: Take a seed pod in one hand, ensuring a firm grip but being gentle enough to avoid crushing it.
  3. Apply gentle pressure: Use your other hand to gently squeeze the seed pod. Apply pressure evenly along its length. This will cause the pod’s walls to split open.
  4. Release the seeds: As you squeeze the seed pod, you will notice that the pod starts to crack and the seeds inside will be visible. Continue applying gentle pressure until the pod opens fully and releases the seeds.
  5. Collect the seeds: Carefully collect the seeds and place them on the newspaper or cloth. Use your fingers or a small spoon to gently separate any seeds that may still be stuck together.
  6. Discard empty pods: After extracting the seeds, you can discard the empty seed pods. Compost them or dispose of them in an appropriate manner.

Repeat this process for each harvested seed pod until all of them have been opened and the seeds have been collected.

It’s important to note that nasturtium seeds are relatively large and easy to handle. However, if you find it challenging to open the seed pods with your hands, you can use small scissors or a knife to carefully cut them open, taking care to avoid injury.

Once you have extracted the seeds from the seed pods, it’s time to move on to the next step: removing the seeds from the pods.

After the nasturtium flowers have faded, wait for the seed pods to dry and turn brown. Then, gently pinch the pods to release the seeds. Store the seeds in a cool, dry place for planting next season.

Step 5: Removing the Seeds from the Pods

After opening the nasturtium seed pods, the next step is to remove the seeds from the pods. This process allows you to separate the seeds from any remaining debris or plant material, ensuring that you have clean and viable seeds for planting.

Follow these steps to remove the seeds from the nasturtium seed pods:

  1. Check for any remaining debris: Before extracting the seeds, take a look inside the seed pod to check for any leftover plant material or debris. Remove any unwanted elements to ensure that only the seeds remain.
  2. Gently separate the seeds: Carefully separate the seeds from the pod using your fingers or a small spoon. Nasturtium seeds are relatively large and easy to handle, allowing you to easily separate them from the pod’s walls.
  3. Discard any damaged seeds: As you remove the seeds, check for any that may be damaged, discolored, or shriveled. Discard these seeds as they are unlikely to germinate successfully.
  4. Collect the viable seeds: Collect the clean and viable seeds in a container or on a clean surface. Be gentle while handling the seeds to avoid any damage or bruising.
  5. Repeat for all seed pods: Repeat this process for each opened seed pod until you have removed all the seeds.

By carefully removing the seeds from the pods, you ensure that only the high-quality, viable seeds are saved for future planting. This step is crucial for successful germination and healthy plant growth.

Once you have removed all the seeds from the pods, it’s time to move on to the next step: drying the nasturtium seeds.

Step 6: Drying the Nasturtium Seeds

After removing the seeds from the nasturtium seed pods, it’s important to dry them thoroughly before storing. Drying the seeds helps to remove any excess moisture, which can lead to mold or rot during storage.

Follow these steps to dry the nasturtium seeds:

  1. Prepare a drying area: Find a dry and well-ventilated area to dry the seeds. You can use a clean plate, a shallow tray, or a mesh drying rack.
  2. Spread out the seeds: Place the seeds in a single layer on the drying surface. Avoid overcrowding the seeds, as this can hinder proper airflow and slow down the drying process.
  3. Avoid direct sunlight: Place the seeds in a location away from direct sunlight to prevent excessive heat and potential damage to the seeds.
  4. Allow for airflow: Ensure there is good airflow around the drying area to promote efficient drying. This can be achieved by placing the drying surface in a well-ventilated room or using a fan on a low setting.
  5. Leave the seeds to dry: Allow the seeds to dry naturally for about one to two weeks. During this time, check on them occasionally to ensure they are drying properly and not showing any signs of moisture or mold.
  6. Check for dryness: To test if the seeds are fully dried, gently squeeze one between your fingers. The seed should feel dry and hard. If any moisture remains, continue drying for a few more days.

Properly drying the nasturtium seeds is essential to ensure their longevity and viability. Once the seeds are completely dry, you can proceed to the final step: storing the harvested seeds for future use.

Step 7: Storing the Harvested Seeds

After drying the nasturtium seeds, it’s important to store them properly to maintain their viability and ensure successful germination when you’re ready to plant them. Proper storage conditions help to preserve the seeds’ quality and prevent them from deteriorating over time.

Follow these steps to store the harvested nasturtium seeds:

  1. Remove any remaining debris: Before storing the seeds, ensure that they are clean and free from any remaining debris. Remove any plant material or empty seed pods that may be present.
