How to Grow and Care

Once you have planted your Hollyhocks, they will need minimal care, but there are a few things you should be aware of when growing Hollyhocks.

First of all, Hollyhocks are a short lived perennial. This means that most varieties will only live 2 to 3 years. Their lifespan can be extended some by removing growing Hollyhock flowers as soon as they fade. If you live in a non-tropical region, cutting them back to the ground and mulching them will also help.

The one benefit that comes from growing Hollyhock flowers is that they easily reseed themselves. While they may be short lived, in their proper growing conditions they will continually grow more, which will keep the Hollyhock flowers consistent in years to come.

Growing Hollyhocks also benefit from fertilizer or compost in the spring.… – See more at: How to Grow and Care for Hollyhocks
