I'm really looking forward to beginning gardening and to eating the fruits (and vegetables) of my labour. Having tried to read around the subject a bit, I'm beginning to get a bit bewildered by the massive variety of different seeds which seems to be on offer.
I'd really appreciate some advice on which varieties I'll stand the best chance with, where I should buy them and so on. If there's a good reliable online shop, that'd be ideal.
I'm based in London in the south of the UK and I've been to local DIY shops and seen that they usually only have one or two varieties of each vegetable seed on offer. They may have two or three different types of potatoes, but for spinach or tomatoes they've usually only got one type. Is this going to be because they're the "standards" that "most people" want to grow, or because they're the best suited to the area or because they're the cheapest or what?! And how do I tell!? Or maybe I'm just getting too bogged down in it and should buy a few packets and try them?
I love spinach and definitely want to grow it, but I do know that you need to harvest about half an acre's worth to make one small portion of cooked spinach and my garden really isn't all that big. So at first I'll probably be cutting it young and eating it raw in salads, but later on I'll perhaps want to eat the adult leaves, cooked. Is there a variety which tastes good when it's cooked as well as raw, or should I grow two different varieties?
I'm also keen to grow rocket and lambs lettuce. I'm not keen on bitter salad leaves: does anyone have any suggestions for other cut-and-come-again salad leaves I might like?
I'd definitely like to grow carrots, spring onions, garlic and perhaps ordinary onions - but again there seems to be a bewildering variety. Does anyone have any advice on the best to choose? Does it just depend on what taste you want, or are some (as I suspect) more resistant to cold, insects (I plan to grow the carrots and spring onions together), rot etc?
I'm so full of questions and really don't know where to turn! Can anyone answer those questions I've posed already and perhaps point me to some wonderful website aimed at beginners that I haven't yet found?!
Thanks in advance
