Garden watering automation. How to organize?

Question

Automation

Hello!
I have a small yard in my apartment building (I live on the first floor), where my mother has planted different flowers and every evening she asks me to water them. In addition, it is inconvenient to open it every evening, go down to the basement and throw the hose into the yard. I would like to automate this process so that every evening at a certain time the valve opens for a while and watering begins. I know that there is a solenoid valve, which apparently works from the supply of voltage.
How can this issue be resolved?
