We've been trying to grow plants from seed this year, and right now we have a set of really tiny tomato plants (2 different species), a couple of tiny bell peppers, and some rosemary. The Rosemary is excellent because potentially it'll be around for years to come. We decided to buy and Early Girl Tomato seedling so that we could start our tomatoes early, and we also bought 2 strawberry plants, which are productive for 2 to 3 years.
So far this season we've spent US$50 on seeds, soil, and seedlings. We used gift cards for most of this amount. And this cost includes a blueberry plant that we've given to my mom-in-law. I'm trying to keep track of money spent on the garden so that we really know what having a garden means financially.
I hope to post pictures mid-week. Please stay tuned!
