Soil

• Pears prefer deep soils with good drainage and a slightly acid pH. Oklahoma State University recommends planting your pear tree in soil of pH 6.5. Unlike many other tree fruits, pear trees tolerate a high clay content well but do better when soils are unlikely to retain much water. Test soil the year before planting and amend drainage, pH, potassium and phosphorous levels for the following year, since soil amendments may be slow to take effect.
  
  

Site

• Pear trees do best on elevated sites that stay warm, since hollows and low sites can retain cold air and encourage spring frost damage. Choose high sites with good air flow to protect sensitive pear blossoms and discourage wet conditions that can lead to fungal diseases. Pear trees prefer full sunlight all day and should be planted where they won't be shaded by buildings or by other trees.
  
  

Time

• Pears are best planted in early spring, before the growing season starts but after the ground has thawed and warmed. Plant healthy 1- to 2-year-old trees immediately upon bringing them home. Do not allow the roots to dry out. In warm climates where the ground rarely freezes, plant pear trees during the dormant season. Late planting prevents the fruit tree from establishing itself properly and increases the risk of insect damage, disease or drought problems later in the year.
  
  

Planting

• Dig a hole large enough to contain the pear tree's entire root ball without bending, breaking or crowding any roots. Prune away all broken or very long roots before planting to prevent further damage. Place the tree upright at the same depth at which it was planted in the nursery, and pack soil around the roots one or two shovels full at a time. Leave a ridge of soil around the edge of the hole as a water ring, then irrigate heavily.
