Spring and summer light days are longer. Even though the light never looks in the north window, it gets reflected and scattered - perfect for many plants that do not like direct sunrays. In summer, it is possible to move ficuses to the north side, excellent leafy ones, such as the Ficus Benjamina. If you have a balcony that goes to the north side, this place is ideal for most domestic plants in the summer. Petunia will bloom on it as well as Pelargonium; we also recommend Phoenix palm and Anthurium.
When winter comes, all the plants are out of the light, not to mention the plants that grow on the north side. This problem can be easily solved with a few daylight bulbs, which will prolong the “light day” and benefit the plants.
