I just took a bunch of spearmint leaves, so when will they grow back? I did some research and a timeframe wasn’t given.
First, the individual leaves will not grow back. The plant in its entirety will continue to grow, and new growth will appear, in various places:
- At the tips of the existing stems, in pairs, effectively making the stems longer.
- In the axils, i.e. where a leaf is connected to a stem. This will happen when the tip of a stem is cut off.
- New shots from the roots will come up.
The overall growth rate will depend on environmental factors, like the season, temperatures, available water and nutrients.
How quickly a plant can regrow harvested leaf mass will depend on the previously mentioned factors and the percentage of lost leaves. A full bush will not be influenced by the loss of a few leaves, but the more is harvested, the less leaf mass will remain for photosynthesis and the more energy has to be drawn from the plant’s reserves.
A simple answer along the lines of “it will regrow in X days” is impossible.
