3. Save Your Seeds
If you have seeds left from your lettuce plant, you should save them. They can be replanted and used to grow new plants. A lot of people don’t realize that they can use their seeds over again and throw them away or just leave them to rot.
Instead of going out and buying new lettuce plants or trying to grow new plants from seeds you buy in the store. Just collect the seeds and move them to a shallow pan or plate. Allow them to dry in the air to remove anything around them that may cause them to stay wet or rot.
You can also shake the flowers of the lettuce plant directly over a pan or plate to collect them and then place them in a dry area to dry out. If you plan to store the seeds, you should label them and store them in an area that stays dry and cool at all times.
