Can orange peel be used as fertilizer for orchids?

How did it wither? If the new and old leaves wither together, it means that you have watered too much and rotted your roots. Go to the basin now! Cut off the rotten roots and plant them when the roots of orchids become soft! After planting, put it in the shade, don't water it. After three or four days, water it! After half a month, it turned into normal maintenance! If it withers from the center of the leaf, it is when you water it that you get wet in the center of the orchid! Don't stop watering until it is dry, and raise it slowly! If the black spots on the leaves wither slowly, it is poor ventilation and infected with germs! Sterilize with chlorothalonil! If the tip of the blade doesn't spread downward at all, you are watering less water.
