ciencies, and solving special nutritional problems, 

 such as getting calcium into apple fruit. For overall 

 economy and tree health, most macronutrients 

 should be soil-applied. 



When applying nutrients to apple foliage, the 

 following suggestions will enhance the spray's effec- 

 tiveness and safety: 



1. Think dilute. Apply fertilizers with as much 

 water as is practical. Effectiveness will be aided 

 via thorough coverage and better absorption. 



2. Watch the weather. Follow the 80/80 rule : avoid 



4. 



nutrient sprays when temperature or humidity 

 values exceed 80 degrees or 80%, respectively. 

 Following this nJe will reduce greatly the risk of 

 fruit or foliage damage. 



Make sure that your sprayer is calibrated prop- 

 erly and that its nozzles are adjusted to direct an 

 even pattern to the tree canopy. 

 More is not better, more often is better. Do not 

 apply too much at one time. If you wish to apply 

 more of a particular nutrient, consider soil appli- 

 cation or repeating the foliar spray at a later 

 date.
