“I wanted to check for tomato seeds my last trip past there, but they were already closed for the day.”
Have you looked at the tomato seeds on Ebay? You can get any kind of tomato you want. Many list their germination rate. You can check the feedback to ensure the seller has a consistently excellent reputation. The seeds are not expensive at all, providing you shop around. It would probably take all day to see ALL the tomato seeds offered. There are quite a few.
That is one thing which really interests me. I've bought seeds at local nurseries, and most seeds did not germinate. The one I usually stop at has non GMO seeds.
