Freeze Damage

• Florida has lost many a citrus grove to below-freezing temperatures that can occur during winter months. Temperatures that are below freezing that last for six hours or more can kill the tree. Fruit exposed to freezing temperatures is not suitable for human consumption.
  
  

Water Damage

• Citrus prefers to grow in well-drained and sandy soils. The summer months can bring deluge after deluge that causes standing water no matter how well the soil can drain, causing citrus root rot that can kill the tree.
  
  

Insect Damage

• An insect mite known as a psyllid spreads citrus greening disease throughout Florida. It is noticed when leaves turn a mottled yellow and fruits are lopsided and never mature to their full color. Trees must be quarantined and reported to the county agriculture extension agency. The fruit or any part of the tree may not be removed from the property. Citrus greening has a severe impact on commercial production of citrus in Florida.
