Phormium Yellow Wave too yellow?
Despite the name, I think my Phormium Yellow Wave is looking a little more yellow than it should. Any advice appreciated.
To give some background, this has been in the same pot for three years. I water infrequently but I’ve watered more recently to get to stave off the yellow ... but it hasn’t had an effect, if anything made it look worse. I also gave it a nitrogen feed about seven days ago but not seen much change in that time.
