I finally got to count my seeds over the weekend. I estimate I have at least 50 different kinds of seeds. The only two kinds of seeds I was missing, so far as I could tell after preliminary checks, were large pumpkins (for making pies) and zucchini. I'll probably have to buy more peas, too.
As far as the garden planning goes, I'm just about set...I think. Every time I come up with a new plan, I end up changing it in a month or so. This cycle repeats itself all winter till Springtime when I have to make the final decision of what to plant where. A great panic ensues until my friend B convinces me this stuff is only going to be planted here one year (the perrenials I always know one year in advance where I'll plant them- I won't even consider them until I already have a specific spot lined up). So if I plant bean seeds in soil with less-than-ideal pH, they won't suffer too badly. Then I just have to try to get them in a better position next year.
My plan this year is just about complete (at least, this revision is) aside from a few herbs. I have everything planned down to the square foot or less of where it will go. I just have to match a few square feet to a few herbs.
