I bought one of those trays pre-packed with peat pots that swell up when you water them. I also got some Martha Stewart organic tomato seeds because, well, they were right in front of me at the store.
Those little seeds are tiny, so I used the moistened tip of a chop stick to carefully get two or three seeds into each little pot.
Yeah, there's a lot of them.
And Martha's none too generous with her seeds - I barely had enough to fill all my pots. But we got it done. I'll post an update when they sprout in (according to the label) 7-10 days.
