To grow gardenias, plant them in a humid and sunny location, add compost to the soil, mulch the plant, water the plant regularly, fertilize the plant, and prune the plant. You need compost, mulch, fertilizer and pruning shears.
- Choose a good location for the gardenias
Choose a location that receives plenty of sunlight and humidity. If the plant is to be indoors, the potted plant needs to be located by a window with direct sun exposure. Run a humidifier near the plant to ensure adequate humidity in the space.
- Prepare the soil
Before planting the gardenias, work peat moss or compost into the soil. Make sure the soil has a pH below 7.0.
- Plant the gardenias
Dig a hole in the soil that is big enough for the root ball of the plant. Place the root ball carefully in the hole, and fill it up with soil.
- Water the gardenias
Water the gardenias immediately after planting, and then water once a week. Avoid splashing the foliage as you water.
- Mulch the plant
Add a layer of wood chip mulch around the base of the plant.
- Fertilize the plant
Fertilize the plant twice a year using a fertilizer for acidic soil.
- Prune the plant
Prune the gardenia plant after it blooms. Remove dead and damaged limbs.
