Tomatoes

  Plant tomatoes where they will get at least eight hours of sun a day. A lack of warmth will limit the number and size of tomatoes produced. Use soil that holds an even amount of water; poorly drained soil can lead to problems such as flower drop, fruit splitting and rotting blossom ends. Sprinkle organic fertilizer in the hole before you place the tomato plant in, but don't over-fertilize. When watering, try not to get the leaves too wet and aim at the base of the plant. Dig a shallow trench around the plant and cut off lower branches so the tomato plant will thrive.
  
  

Peppers

  Plant peppers outdoors after the last frost has occurred in an area that receives the most sun. Space the plants 18 to 24 inches apart in rows that are at least 24 to 36 inches apart. Although peppers need to be watered daily during the hot summer months, make sure the soil is only moist and not wet. Add mulch around pepper plants to retain moisture while keeping weeds out.

  Soil temperatures from 70 to 80 degrees and full sun of up to eight hours a day are ideal for green beans. Plant the green beans 2 inches deep during the late spring, up to 4 inches apart. They should have at least 1 inch of water every week until the pods start to develop.
  
  

Cucumbers

  Cucumbers need full sunlight to grow in well-drained soil. They grow the best in soil that is 70 degrees on a consistent basis. Do not plant the cucumber in low areas that accumulate water because it will make the cucumbers rot. Fertilize on a regular basis with a high-nitrogen fertilizer for the cucumbers to grow successfully. Plant cucumbers away from tomatoes.
