I have been gardening for a long time, my backyard is an ideal place
because my backyard is facing south with full sun. I am  firm on organic
growing of my vegetables. I spray my garden but not with pesticides.
Here are 7 tips to help with your gardening.
1 Plant your garden in full sun light
2 Use Trellises for tall plants, like Tomatoes
3 Seeds for your area you should start indoors
4 Bush type squash takes up less space
5 Always have a plan so tall vegetables 
    will not shade other vegetables.
6 Trellises should be placed where tall plants
    are planted especially climbing vines

7 This is what I use for spraying my vegetable garden
     take a spray bottle add two or three drops 
     of dishwashing liquid add water shake gently you may
     have to spray everyday but it works and keeps the
     pests out 
     You will have to respray after it rains also, as the spray      is washed off from the rain.
