Planting calendar

I started my balcony garden because I wanted to see if I can grow fresh vegetables, but I did make some rookie mistakes. After I got in trouble with some of the crops I actually started researching and I found a very nice calendar for planting.

As it can easily be seen, most of the things I planted very very late, so they aren't doing as well as they should.
So, I am planning better for the fall.
For example, I plan to try again in the fall with cold season crops - spinach, lettuce, radishes, rucola, carrots, cauliflower, peas and beets, because they seem to be doing better with lower temperatures.
I do have a batch of carrots that I moved inside and they seem to be doing well. I also planted a type that grows small round roots like a radish instead of the long one, I hope it's not too hot for them to grow. I'll move them inside just in case.
However, the tomatoes are doing absolutely great and so are the cucumbers and beans - today I actually noticed that my green beans are starting to show up!
So, if you are thinking about growing veggies, plan before you sow :))

Also, I'll add a list of useful links
