My potted gardenia is starting to get brown spots on the tips of the leaves. It is con't to bud & bloom but the flowers are not their normal robust size. 5 weeks ago I transplanted into a bigger pot using Miracle Gro potting soil & the plant seemed to be thriving doing very well. The new pot has plenty of drainage. I live in South Florida & the weather is starting to hit 80 degrees during the day. Any ideas on the cause of these 2 problems.
Thank you
