1. Revive Ferns


Castor oil can come in handy to fern fronds and make them look lush again. Mix half a teaspoon of baby shampoo and castor oil in a gallon of water. Add this solution to a spray bottle, shake well, and spray it all over the foliage to make it shiny.

Do this once in 6-8 weeks for best results. Avoid spraying the plant with this solution every week.
