I Have Read That You Should Fertilize Avocado Every 3 Months
I have read that you should fertilize avocado every three months. I fertilized with 16-16-16 in May. My tree now is full of fruit. Three months have passed. Should I fertilize again? What should I use?

Outdoor trees benefit from fertilization in February through September. Use a balanced fertilizer, like what you have with the 16-16-16, bi-monthly or as needed. You should increase the phosphorus (middle NPK number: 16-30-16) during prior to fruiting, though a balanced type will not hurt it.
Those indoors are normally fertilized with a balanced, water-soluble food monthly.
