Gardenia's blooms are yellowing and dropping...
I purchased a beautiful gardenia shrub from a farmer's market a couple of weeks ago -- 3 gallon pot. Immediately repotted into a very large (2-1/2 foot diameter) pot to go on the patio. Pot was filled with an organic, tried and true potting soil.
I realized quickly that they don't like full sun -- within 2 days some of the white petals were scorched.
I moved it to the front porch corner, where it only gets a bit of sun in the mornings (about 1-2 hours' worth), then total shade in the afternoon/evening.
The petals aren't burned anymore, but the white blooms are turning lemon yellow and falling off. I have pulled some off to hopefully encourage more blooming, but some are now falling off on their own.
The leaves look spectacular -- green and waxy/shiny, full and no sign of over or under watering. That's what has me so confused. I only water every other day IF soil feels dry.
New buds are forming all over, too -- none have opened yet, but I notice new buds daily.
What would make just the blooms be suffering, not the leaves? They seem to be falling off and suffering from the top down, I might also mention. Right now the only white blooms left on the plant are near the base of the shrub -- and more of those are turning more yellow-ish daily.
Haven't given it fertilizer yet as a gardener friend told me to wait till late June. (Acid-loving plants tend to like Osmocote with the purple lid, so I have heard.)
