Anyone who cooks a lot of Italian dishes understands the importance of having a steady supply of fresh Roma tomatoes. A main ingredient in many recipes, Roma tomatoes are used in sauces and ketchup and canned for use as chopped tomatoes and tomato paste. Roma tomatoes, also sometimes called plum tomatoes, grow on short bushes rather than vines, and mature within 80 days of planting. Collecting and saving the seeds from your harvest will ensure that you have fresh Roma tomatoes year after year.
Label the envelope with the variety of Roma tomato and the date on which you will be storing the seeds.
Place your collected Roma tomato seeds into the envelope.
Fill the fabric bag with the powdered milk and place it in the bottom of the jar.
Place the envelope inside the jar, on top of the milk pouch, and seal the jar tightly.
Store the jar in the refrigerator or other area that remains cool, dry and dark. Do not open the jar until you are ready to plant the seeds. The Roma tomato seeds will be viable for up to 10 years.
