Which practice can help increase flowering in plants?

Deadheading spent blooms is an effective practice to encourage increased flowering in plants. When flowers fade and begin to wilt, they can divert the plant’s energy into seed production rather than producing new flowers. By removing these old blooms, you are signaling to the plant to expend its resources on creating new flowers instead. This process not only enhances the overall appearance of the plant but also extends the blooming period, as the plant responds to the absence of mature seeds by producing more blossoms.

In contrast, overcrowding the plants can lead to competition for light, nutrients, and water, which can inhibit flowering. Regularly rotating the plants might have some benefits in terms of light exposure, but it does not directly promote flowering as deadheading does. Only using natural sunlight can be limiting because, depending on the plant species, they may also benefit from supplemental lighting, especially in lower light conditions.
