Fan leaves are a plant’s largest solar collectors. They are also factories where nutrients are taken in and processed into sugars and essential chemicals that are then used by the entire plant. Removing the largest solar collectors and factories is not beneficial to plant growth or maturation.
 
In many cases if a large fan leaf is shading a budsite the leaf can be pulled to the side and tucked under a branch or a branch pulled up between the fan leaves, and other things can also be done that does not involve removing the fan leaves, so there are ways keep them and to increase light penetration to the lower portions of plants.
 
Also what many do not know is while leaves appear green and solid in color to the human eye that is only the reflection of light off chlorophyll. Leaves are actually very translucent and light will penetrate through them to the lower portions of plants.
 
Why do you think a 400-watt light penetrates deeper than a 250-watt light and a 600-watt light penetrates deeper and a 1000-watt light penetrates even deeper? Is it because the light twists and turns and goes around leaves and reflects off of reflective wall surfaces or might it possibly be because leaves are actually very translucent and the higher intensity light just passes through more layers of leaves than lower wattage lighting does?
 
Unless fan leaves are obviously dying, and are about half dead or more, leave them on your plants because they will be far more beneficial to your plants on than off.
