Get a soil test - GET A SOIL TEST - Oh Yah - get a soil test.....
Why ??
think about as how you eat and how plants eat... having a balanced diet is best, this includes veggies, fruits, meat, dairy and grain. The same holds true for growing plants, but at this level, you need to know the elements are in or not in the soil, which you gain through a soil test.
It may cost 20-40 bucks but worth it... it gives you a map of where you are now and where you need to go, so you plants have a balance diet..... of teh right PH and (phosphorus, potassium, calcium, magnesium, sodium, sulfur, manganese, copper and zinc)
I have seen and used soil testing kits at local home and garden stores. I got mine at Theisen's.
I plant green beans and they are very easy. Pick them when they are very slender and you won't have to cook them as long. I use steamer bags in the microwave which is very fast. I also cook them in a skillet with a lot of water and when the water is gone I put oriental sauce on them and stir fry.
I did not have good luck with pumpkins because of some ugly bug and they just would not grow well.
Strawberries grow by themselves but tend to grow ever wider each year so you have to yank out the new runners to control them.
Onions and garlic take care of themselves also. Tomatoes are nice, just so you go out every couple days and kill the caterpillars that eat them.
Plan to weed once a week faithfully and use other methods if you can. For instance I put newspaper and grass clippings around tomatoe plants.
