To keep your Stephanotis happy and to get your blooms to return this summer there are a few simple, easy steps to follow. After your blooms have passed and it warms up outside you can place your Stephanotis outside. Keep your plant in a well lit area, away from the direct sunlight as this may scald the leaves. In the summer the ideal temperature for Stephanotis is 21ºC. These are high humidity loving plants. If you would like to keep your Stephanotis outside during the summer you should place it in a humidity tray. To make a humidity tray find a pot without drainage that is large enough to fit your potted Stephanotis inside with about 2 inches of gravel in the bottom. Place the gravel in the bottom of the no drainage pot and pour water onto the gravel until it is about 1/2 an inch below the surface of the gravel. Then place your Stephanotis in the pot. As the day warms the water will evaporate from the gravel and provide your plant with humidity.(Hint:This humidity tray is something that most plants would love to have if you want to place them outside in the summer). During the summer months you will want to fertilize every 2 weeks with a fertilizer high in potassium (The 3rd number in the fertilizer code). You will want to water regularly throughout the growing season.
During the winter month Stephanotis do not grow much so you will want to water sparingly. Do not allow the soil to completely dry out, but make sure the top inch of the soil is dry before watering. Temperatures between 13-15ºC are ideal for, although they can tolerate temperatures as low as 10ºC.
To repot your Stephanotis you will want to wait until the end of the plants dormancy period, which is in late March-April. You will want to chose a potting soil rich in compost and organic matter. A suitable mix is African Violet soil which is designed for plants that require rich compost and lots of organic matter.
