Asparagus fern is suffering and yellow HELP
i've got what i think is an asparagus fern. I've had it 6 years now. It lives in my fountain at work. The roots have grown completely into the water so it's not a dirt plant anymore, totally hydroponic.
here's my problem- my poor paul bunyan (named that since he sprouts a new shoot constantly and grows like a beanstalk) has recently gone from beautiful green and thriving to green, brown and yellow. All my co-workers are concerned. I'm sick over it and don't know what to do.
We moved offices recently and he got put in the direct sunlight (which hadn't bothered him before) and right under the air conditioner vent. The yellowing took about 1-2 months.
Our plant lady thought it was too much direct light so i moved him and got him out of the direct air flow as well. We also fertilized him but to no avail.
HELP! Paul has got to recover but i don't know what to put on him. I apperciate any help you can give me.
