Gardenia fertilizing question
I have three gardenia planted next to my deck: August beauty, vetchii and mystery. I am in San Jose. the plants have eastern exposure and a nice acidic soil condition with plenty air and correct temperature swing from day to night as they are next to an open sided deck.
The August beauty has the habit of setting tons of flowers and then having the dreaded yellow leaf/green veins that indicates iron deficiency, the poor dear. The other two are more steady slow bloomers while miss August seems to do it in flushes.
Here is my question: is it the heavy bloom that takes nutrients away? Is it because this plant is between the other two and staying too warm? Also can I fertilize this one ( between the other two) more often without hurting its neighbors?
