Spring is the best time to repot your houseplants! Really you can do it anytime of the year if your plant is outgrowing their current pot. But for best results, wait for growing season, the start of spring. Not only is it good to repot in the next size up, but it is good to refresh the soil. Most ALL my plants stay in the pot they come home in from the nursery, allowing them to get used to their new environment. Besides repotting in the spring, I only repot if I the plant isn’t retaining water, or root bound (roots are taking over). Today I am repotting two of my Ficus Triangularius plants.
