Humidity is an important factor, especially when you’re growing Spanish moss indoors. To avoid it from drying out of the middle or rear drives, spray it from all sides.
Spanish moss doesn’t need fertilizer instead it is itself used as a fertilizer. However, if it is growing poorly or discoloring, spray it with compost tea diluted half with water.
Simply snip off the ends using a sharp tool to prune it back lengthwise. Avoid over pruning as it results in side-shoot formation.
In summer provide it a light shade and increase watering. Soaking the plant also benefits extensively in hot summers.
