1. Absence Of Flowers On Few Avocado Trees. 2. Optimal Fertilizer NPK Values For Spring Application

Question

1. What might ne the cause for absence of flowers on few avocado trees whereas most of the trees are fully covered with flowers? These trees are looking perfect, fully covered with healthy leaves…but without a single flower. 2. In a post named “Fruitless Avocado Problems – Reasons For An Avocado Tree With No Fruit” published On April 13, 2021 by Amy Grant, she mentioned a note saying: From April through June (Northern Hemisphere), refrain from feeding the trees with a nitrogen rich food in order to promote fruit development. What will be the optimal fertilizer NPK values to achieve this goal and which Nitrogen source still left should be used? mostly potassium nitrate? or rather mainly ammonium nitrate? and how much should I dilute the fertilizer to be applied? My trees belong to the Reed cultivar. Appreciating your reply
