Planting Location

• Geraniums come in many vibrant colors.geranium image by photografika from Fotolia.com
  
  Geraniums require four to six hours of sun a day to bloom well. According to Oregon State University, geraniums do best with some midday shade during hot summer days. They flourish in a wide variety of landscape locations, such as in beds, borders, window boxes, containers and hanging baskets.
  
  

Soil Requirements

• Geraniums do well in containers.geranium image by szildy from Fotolia.com
  
  Geraniums grow in a wide variety of soil types, but must have good drainage. Amend heavy clay soil with compost. For container cultivation, use a light-weight potting mix with added perlite or pumice.
  
  

Watering and Mulching

• Drench geraniums each time you water, but allow the first two inches of soil to dry before watering again. Apply a 1- to 2-inch layer of mulch around plants to keep the soil moist. Never leave potted geraniums sitting in a wet saucer.
  
  

Fertilizing

• Geraniums require feeding to avoid stunted, yellow leaves. Fertilize at planting with a dry 10-20-10 fertilizer and again every four to six weeks during the growing season with a water-soluble liquid food. The University of Rhode Island website recommends a 20-20-20 or 15-30-15 liquid fertilizer.
  
  

Pruning

• Pinch off spent flowers and yellow foliage to promote healthy, bushy plants.
