The
Common mallow doesn't necessarily need to receive high volumes of fertilizer each year, which means overfertilization is entirely possible. If you overfertilize your
Common mallow, you will likely notice first that the leaves have turned brown.
Overfertilization of
Common mallow is especially common if you use a fertilizer that has higher concentrations of nitrogen. High nitrogen content will likely cause the leaves of your
Common mallow to become discolored, lose much of their moisture, and begin curling at the margins. Many gardeners avoid such complications by limiting fertilization of their
Common mallow to once per year in early spring.
