Thanks so much for the information!!
Which soil would you recommend? We used Miracle grow made for vegetables but they still didn't seem to grow. Partially because they have scorched on some days but I would of at least expected a small vegetable to form!
Like Zigs has already said, a good multi-purpose compost works well, that is, if you don't make your own compost, but it does need to be a good quality soil based one, and one of the best on the market, if it is available in your area is 'John Innes', which is the No.1 choice of many professional gardeners
Regarding fertilizer, many commercially made composts come with feed pellets already incorporated in the compost, but because, as Zigs said, the level of fertilizer in the compost depletes quite quickly, I tend to use the sustained release feed pellets, which normally last for the entire growing season and only have to give extra feed to the extra hungry plants like tomatoes, which always seem to have an insatiable appetite
As for your scorching, this could also be caused from moisture left on the leaves after watering, which when, then exposed to strong sunlight, can burn the leaves or even fry a young plant, so it is always best to water the soil around the plant and not the leaves if watering when the sun is up.
You don't say what sort of climate you are gardening in, but this is where I would disagree with Zigs regarding sunlight, as I garden in a climate where we receive long hours of unrelenting, scorching hot sun for up to 10 hours a day, combined with temperatures that are regularly in excess of well over 40 degrees centigrade for months on end. Although none of my, nor my neighbors plants have any form of shading , apart from the occasional exploding watermelon - we have never had any scorched or fried plants, only a very bountiful supply of fruit and vegetables

but if gardening in these conditions. you need to make sure that the plants are thoroughly watered in the morning prior to the sun coming up.
I may well be wrong on this one but I'd always understood that most vegetables required at least 6 hours of sunlight a day in order to produce well, and that if giving some shade, this was best done during the hottest part of day, which can of course vary, depending on which part of the world you are in.
