Doe the pyracantha in the picture look ok? leaves are turning a bit yellow and unsure if this is normal???
yes it's ok, it's just new growth. I'm surprised you're getting any in this weather, mine haven't started yet...
I have one in a pot - waiting to go in the border - and it has quite a lot of new shoots.
If you are concerned you could give it a feed - growmore is easy, or wait until the weather(maybe) improves and give it a lquis one then
I have just sprinkled Blood, fish and bone at the base of all my flowering shrubs
