The days are shorter and the light is less. For this reason, we move the plants that need a lot of light closer to the windows. We are ramping up fertilization on all plants now that the temperature is cooler. Poinsettias & Patience: It is essential to increase the hours our plants are in the dark in order to speed up their flowering by Christmas. These plants need about 14 hours of darkness over a 6 week period to flower. We plant annual or biennial plants that flower in winter and spring (eg pansies, carnations, dogwoods, chrysanthemums, daisies) when the weather stabilizes at temperatures around 20°C. We plant bulbs. This month we should also plant the tulips. Water the bulbs that have been planted and sprouted sparingly. We often collect the fallen leaves because they are foci of infection with the rise in humidity.
