When you select your variety of gardenia, keep in mind that most gardenia varieties grow better in tropical and subtropical climates. The Kleim's Hardy Gardenia is one of the only gardenia varieties that can withstand relatively cold temperatures. Other varieties that are more suited for colder weather include Chuck Hayes and Frost Proof. Gardenias need a home that receives full to partial sunlight. They like the warmth of the sun for proper growth. Strive to give your gardenia direct morning sun rather than direct afternoon sun. If you are putting your gardenia in an indoor pot, you will want to keep it near a south-facing window so that it can get bright, indirect sunlight for most of the day. Gardenias grow best when they are planted in rich soil that is moist but well-drained. Gardenias do best in soils with acidic pH levels. Try to maintain a pH of 5 or 6. You may want to have your soil tested and then add nutrients according to the results. In particular, if your soil is too basic you will want to add sulfur.
