Planting in the Ground

• 1). Dig a hole that is twice the size of the kumquat tree's root ball and at the same depth as the plant is planted in its nursery container. The depth of the hole should allow the grafting union to sit 2 to 3 inches above the soil line.
  
  
• 2). Set the kumquat tree on its side and twist off the container. Place the tree inside the hole. Pack soil around the base of the tree. Water the area to moisten the soil.
  
  
• 3). Spread a 3- to 4-inch layer of mulch 12 inches from the base and beyond the dripline of the tree. Avoid allowing the mulch to touch the trunk of the plant, because it encourages diseases.
  
  

Planting in a Container

• 1). Cut window screen mesh to fit over drainage holes at the bottom of your container. Place the pieces of mesh over the drainage holes to keep soil from draining out.
  
  
• 2). Pour sterilized potting soil into the container. Fill the container three-fourths of the way with potting medium. Create a hole inside of the potting medium that is twice the size as the kumquat tree's root ball.
  
  
• 3). Place the kumquat tree in the hole and pack soil around the base. Allow 2 to 3 inches from the graft union to the soil line. Covering up the graft union promotes diseases.
  
  
• 4). Tilt the container and pour rain or bottled water around the base of the kumquat tree until water flows from the drainage holes. Using rainwater or bottled water prevents salt buildup in the soil.
  
  
• 5). Place the container on a saucer that has a 1-inch layer of pea gravel to promote drainage.
