This lovely plant sat outside on my deck, unfortunately its got some yellowing on the tips of the leaves. Is it okay to cut those leaves off, or is there a better idea?
First, by 'Cast Iron Plant' do you mean Aspidistra elatior? A better idea would be to figure out the reason for the yellowing and then correct it. Moisture, too much/too little? Time for a repot? A photo would be of great help in diagnosis.
Looks like the sun/drought scorch we see often in Texas. Have you kept it in the shade at least from 2pm onwards?
