Yellow leaves on Boxwood Beauty Natal Plum
Hi everyone! I just signed up with this site, and this is my first post. Would like to thank you all in advance for any help!
We just got our front yard landscaping done three weeks ago. There are a few boxwood beauty natal plums. One of them has started to develop yellow leaves in the lower half of the branches and does not appear to be doing so well. Could anyone tell me what could possibly be causing this problem? Over-watering, fungus, or lack of certain nutrients? (Another one sitting a few feet away seems to be doing just fine)
Here's some background info. Since they were planted not long ago, we are watering the shrubs four times a day, 3 minutes each time. Since we use the adjustable emitters, natal plums are not getting a whole lot of water. Whenever there is rain, I shut the timers for 24 hours. This natal plum is getting a few hours of afternoon sun every day.
Thanks a lot!
