Roebellenii palm

I have a Roebellenii palm that I have had for a bout 3 years.
It stays in doors in the Winter and I have repotted it.
No matter what I do the fonds/leaves are not a Lush green like they should be.
I have bought some miracle grow and wonder if I should spray the leaves with it.
Can anyone recommend something that will make it look nice again.

 

You could try epsom salts, it takes a while to react though.
You can get a plant tonic that contains a good few trace elements, might be worth a try.

 

Thanks Pete.

 

Maxicrop / some sort of seaweed concoction perhaps?

And/or Rock Dust??

or maybe even Palm Booster (there's another Palm one, I've forgotten then name though)

 

Palm focus maybe?

 

Where is it situated ? It could be not enough or too much light, too dry? they should never dry out even in winter.
