Gardenias are one of the more difficult
plants to grow and bloom indoors successfully. Gardenias are not easy to bloom indoors because they have rather strict temperature requirements. Temperatures between 55 and 65 degrees are essential when gardenias are in bud or bloom. Bud drop occurs above 70 degrees. Bud deformity occurs below 55 degrees. Letting the soil get too dry will also cause bud drop. In addition, a change in environment will also sometimes cause bud drop.
Direct sunlight, high humidity, and acidic soil (5.0 pH) are also important for maintaining gardenias successfully. Avoid repotting until it is utterly potbound. Use an acid fertilizer, such as Miracid, but don't overdo it. Good luck with this challenging
plant!
Kalanchoes must have bright indirect sunlight all day with a few hours of early or late day direct light. A minimum of 4 hours of direct sun every day is essential for flowering. Do not repot it and avoid fertilizer for the first year! It is a
succulent and likes dry soil, but will not go for a long time without any water as a
cactus will. It prefers warm temps, never below 60 degrees. To extend
flower life, provide temps in the 50 to 70 degree range. It is a “short- day”
plant that will
flower at any time of the year. However, to set buds it must have at least 16 hours of completely dark nights for 3 months. This is more than most owners can manage. That is why this is often used as a "throw-away”
plant that is discarded after it finishes flowering.
I don't mean to discourage you here, but thought you should know what these
plants need to thrive and
flower once again. However, if you are satisfied keeping them as foliage
plants, then they are a lot less demanding.
