Gardenias are beautiful and fragrant flowers that can be grown in Arizona with proper care. Here are some tips for growing gardenias in the hot and dry climate of Arizona:

1. Choose the right variety: Select gardenia varieties that are more tolerant of heat, such as “Veitchii” or “August Beauty.”

2. Plant in a suitable location: Find a spot that receives partial shade and has well-draining soil. Avoid planting in areas with strong winds or full sun exposure.

3. Provide ample water: Gardenias need regular watering to thrive. Water deeply, keeping the soil moist but not waterlogged. Mulching can help retain moisture.

4. Protect from frost: Gardenias are sensitive to frost. Cover them during cold snaps or bring them indoors to protect them from freezing temperatures.

5. Fertilize regularly: Use a fertilizer specifically formulated for acid-loving plants like gardenias. Follow the instructions on the package for best results.

Growing gardenias in Arizona can be challenging, but it is possible with the right care. When growing gardenias in the Arizona heat, it is important to monitor them closely, especially during hot and dry periods. The most successful method is to grow gardenias in containers and place them in shaded areas. When temperatures reach 115 degrees, it is crucial to thoroughly water the gardenia plants. To achieve the best results, use bark chip mulch, fish emulsion fertilizer, and coffee grounds.

Step 1

Select a gardenia variety that thrives in the Arizona desert. Gardenia jasminoides is a recommended choice.

Step 2

Plant the gardenia in well-draining soil that is acidic and rich in organic matter. If your Arizona town does not have this type of soil, it is best to grow the gardenia in a container filled with high-quality, organic potting soil. This can be purchased at any home and garden center.

Step 3

Dig a large hole in the ground to place your potted gardenia. This is the ideal method if you want to grow your gardenia outdoors. The hole should be large enough to accommodate the pot with an additional 12 inches of space underneath. Adding gravel at the bottom of the hole will improve drainage around the roots.

Step 4

Plant the gardenia so that the top of the root ball is level with the top of the potting soil. Gently disturb the root ball to encourage root growth into the surrounding soil. To improve water retention, cover the soil with a layer of ground mulch or fine bark chips.

Step 5

Provide shelter from the hot afternoon sun for your gardenia. It is important to keep the soil consistently moist, especially during the summer months. Water the plant twice a day to prevent it from drying out. Additionally, apply a slow-release fertilizer in March and every 3 months thereafter.
