Yew turning brown and losing needles

I have a yew that is turning brow and losing its needles. What can I do to help it?

 

If it has been in the same pot for longer than 2 years then gently remove it from the pot and check the root ball.
The problem is probably stemming from the roots (pardon the pun)
Drainage might be a problem
Over fertilising is another thought

 

Probably either needle blight or root rot. With dead tips + green interior fitting the first condition in particular.

 

Hi, I had yews in pots many years ago and the same thing happened to mine. The problem was not looking after the soil / compost.
I lifted them out of their pots and the compost had disappeared and the root ball was tight.
I purchased three new larger pots added soil and compost, teased the roots all round the rootball and repotted them. I did this every two years for the next 20 and all picked up and still look healthy today. My children now have two of them in their gardens and I still have one all three are doing well. I have posted mine to show you.

 

Actually the example shown in the last picture does have a percentage of dead stem tips.
