Are coffee grounds good for gardenias?
Gardenias will appreciate coffee grounds mixed into the soil as well.

Coffee grounds can also be used as a soil amendment. They can be added to the top of a compost pile, or added directly to a potting mix.
Coffee grounds should not be planted directly in the ground, as they will quickly decompose. Instead, they should be placed in a container and allowed to aerate for a few days before planting. This will help them to break down more easily.
How do you keep gardenia leaves green?
Gardenia’s leaves turn yellow and drop, aside from the normal aging process of its leaves, this may be caused by any of these reasons: Over-watering or under-watering: Gardenias need at least 1 inch of rain (or equivalent watering) each week.

Gardenias do best in a well-drained soil with a pH of between 6.5 and 7.0. Too much water or too little soil can cause the leaves to turn brown or yellow, which is a sign that the plant is over-watered. Watering too often or not enough can also lead to yellowing of your leaves. If you fertilize your gardenia with too much fertilizer, it will not grow as fast as it should.
This is especially true if the fertilizer is applied too early in the season, or if it is not applied at the right time of the year. In addition, excessive fertilization can damage your plant’s roots, causing it to wilt and die.
