1. Choose the right soil

The double-petaled hollyhock does not have high requirements for soil when growing. This plant is particularly resistant to alkali, but it likes fertile, loose and well-drained soil. In addition, this plant grows fastest in sandy soil with a high organic matter content.

When dividing, you can dig out the roots of perennial double-petaled hollyhocks, and then use a knife to cut them into multiple small clusters, so that each small cluster has two to three buds, and then plant them in the prepared pots.

3. Adjust the temperature

Double hollyhocks have high temperature requirements when they are cultivated. This plant grows fastest when the outside temperature is between 25 and 30 degrees. After it enters the flowering period, the ambient temperature should be controlled between 26 and 28 degrees.

In addition, after entering winter, the double hollyhocks should be moved to a warm room in time, otherwise the temperature is too low and its leaves will turn yellow, and in severe cases, it will die.
