This forum is good for general advice but could I also suggest get some reading matter from the library or buy from charity shop-there are loads of books that will help a beginner like yourself
Also as a novice keep it simple-a lot of gardening is relatively easy and common sense but you need to know what plants will survive a winter and those that don't like frost and what flowers when.
We all started somewhere and there is plenty of help on here-just don't try to do it all at once
