Whether it’s saving pumpkin seeds (above) – or seeds from any of your vegetables, a few tips and tricks can go a long way to having great seeds on hand for great plants next year!

Especially when you take seeds from the fruit when the plant is at it’s peak. And that is exactly why mid to late summer is the perfect time for saving seeds!

How To Save Seeds From Vegetable Plants – 3 Secrets To Success!

#1 Save Your Seeds In Mid Summer

The first fruits and vegetables produced on plants tend to be very small and a bit immature. Most of the seeds that form early are likewise not as developed. Because of this, they do not make good candidates for saving.

Late season fruits are not the best choice either, but for a few different reasons. Late in the year, the seeds in fruit often have more of a chance to be cross-pollinated from other varieties and crops. That means you can end up saving a seed that is not going to replicate your current plant.

Seeds can be quite expensive to purchase year after year, but by simply saving back a few from your open pollinated plants, you can grow for free!

That leaves mid-summer as the absolute best time for seed collecting. For starters, always make sure you are picking from the healthiest and most productive plants in the garden. Plants that show signs of disease or stress can have less than ideal seeds.

In addition, select fully mature vegetables that are ripe. This will ensure that the seeds within the fruit are also mature and have the best chance of germinating.

#2 Save The Right Seeds – How To Save Seeds From Vegetable Plants

When saving seeds, it’s important to know that not all seeds from every plant can be saved. The best seeds to save are heirloom open-pollinated seeds.

An open-pollinated seed is one that develops within the fruit of the plant, and will continue to produce the same crop and the same exact seed, year after year. You can find open-pollinating varieties of seed for nearly every vegetable under the sun.

Seeds That Shouldn’t Be Saved – How To Save Seeds From Vegetable Plants

Unfortunately, you cannot save the seeds from all vegetable plants. And at the top of this list of the non-saves are hybrid plants.

Hybrid plants are created by crossing two or more varieties of a vegetable plant to produce a new plant with new qualities. They can be fantastic plants and produce wonderful results. But the only issue is that the seeds from these plants will not produce the same plant the following year.

Instead, when seeds of these plants are saved, they usually will revert back to grow a version of one of the original plants. In some cases, the plant will produce the original fruit, or because of the mutation, no fruit at all

Now that you know what you can save, let’s cover how to save your seeds! The process for saving vegetable seeds is nearly identical for every vegetable plant except tomatoes, which require an extra step to ensure success.

First we will cover the more traditional seed saving, and then take a look at how to save your tomato seeds as well.

#3 How To Save Seeds From Vegetable Plants – The Process

After selecting your vegetable, begin by cutting it in half. Next, gently scrape the seeds from the core, being careful not to damage the seed coating with your knife or scraper.

Next, lay the seeds on a dry paper towel, and place in warm, sunny location to dry. It will usually take a few weeks for seeds to dry out completely. Once dried, take a new piece of a paper towel, and fold the seeds up inside of it. The paper towel is great for absorbing any moisture that might still be in the seed. It will also help protect the seed from any damage from light.

Store in an airtight container or plastic bag, and keep in a cool and dry location. You can keep your seeds in the refrigerator for a longer shelf life. However, if you will be using the seeds the following season, cold storage is not necessary.

About Those Tomatoes…

Saving tomato seeds is not difficult but it does take a few extra steps to ensure success. Tomatoes have a natural, protective coat around their seed. And without helping the seed break down that outer coating, they struggle to germinate.

Allowing the seeds to dry out on a paper towel will help in absorbing extra moisture quickly.

But fortunately, the process to break down the coating is simple and easy. It all boils down to letting the seeds rot or ferment.

Start by selecting the tomatoes you would like to save, and then scrape the pulp and seeds into a small jar or container. Let the container sit for a few days until it develops a bit of mold on top. Although it might look a bit funky, it is the mold that works to break down the protective coat.

It is a good idea to store the container away a bit as it can produce a bit of odor. After a few days, simply rinse the seeds off with water and allow them to dry out like the other vegetable seeds.
