This is the second season of having my fatsias. They are planted in a shaded area as recommended. Last year they did well, this year it doesn't appear that they are. It's losing leaves around the bottom. Is this normal? It also has leaves that don't appear very healthy. Instead of being it's normal lush green they're dull and even yellowing. It does have new growth so that's reassuring. Any advice would be very much appreciated!
