There should be a process, such as from the room to the window, to the balcony, and finally out of the room to adapt these delicate flowers and trees. At the same time, we should pay attention to adding some flower fertilizer to these precious flowers to ensure their future growth. Spring is not only the time when everything wakes up, but also the peak of pest growth. At this time, friends who grow flowers should pay special attention, because the flowers you care for may be suffering from pests and diseases.
