Yellow Leaves on Gardenia Bushes

Anonymous added on April 18, 2011 | Answered

I've noticed that just recently the leaves on my gardenia bushes are more yellow and falling off. I'm wondering if I'm watering them too much. I have an automatic irrigation system. I have it running three days a week, at 40 minutes each time. I think the frequency is fine but perhaps the duration of 40 minutes is too much. Should I cut this in half to 20 minutes each time?
