Therefore, cosmos is very suitable for lazy people and novices to plant and cultivate, while zinnias require experienced gardeners to take care of them.

The ability of cosmos to adapt to the environment is very strong, and its cold resistance is also very high. Generally, the best time to plant cosmos is from November to March of the following year.
