No.. plants don't waste energy.. they use whatever they can get. Cutting the leaf off may open up a lower section for more light, yes.. but it will stress the plant to cut parts of it off..
If you do decide to prune fan leaves off.. do one at a time.. every few days.. never cut more than 2 fan leaves off in a day.. as it really is unnecessary.

What do you think the plant uses to catch that energy from the light??

The Fan leaves..


Try tucking.. and tying.. you can manipulate the growth of the plant just as well and not worry about cutting parts of it off before it's time to.

Hope this helps,
Bob.
BobBong Reviewed by BobBong on . dont want any newb answers to my Q Based on experience and reliable sources is there any problem with pruning (cutting fan leaves off)? imo if the leaf is blocking light to branch growth it would be more benefitial to cut it. and if its not getting any light then its useless and just wasting the plants energy to keep it alive. pro answers only Rating: 5
