New lottie soon and what to plant now.

Contacted my Parish Council about getting an allotment and the clerk called me back today. He says that he will have a better picture of how many plots are available in a week or so, after the yearly rents are collected or not as the case may be.
He said I'm on the list now and cannot see any problem with me getting a plot straight away! Yippee!
Although I do feel a bit guilty that some people have been on waiting lists, in other areas for months/years.

We have 2 sites in our village, the big one is surrounded by houses and has no sheds. I've gone for the smaller site as it's closer to my house (8 mins walk) and does have sheds on it - I must have a shed, a place to escape from my noisy neighbours pounding music
This site is also surrounded by fields and hedgrows and is a lovely place to be.

The rent is only £14 a year (£7 for OAP's). Bargain!

Now I'm a bit worried as I have never had a plot before. I have read lots of advice on here about taking it steady etc. Well noted.
However, what can I get planted straight away, bearing in mind I probably won't get the plot until November. I hear some people are planting garlic now, will November be too late? Anything else worth planting now?

Thanks in advance.
