Watering crops

I have purchased several sprinklers yet I keep having to water some of the plants. It's really slowing me down. Also is there a way to take care of the crops such as replanting the ones that died without having to start a game. When I need to replant the dead crops I can't figure out how to do so without starting a new game then I have to wait till time runs out then start again.

The sprinklers have a certain radius. If you plant like I do it will help.

Put the sprinkler in the center. All of your plants will be watered.

Planting is easy.....you really should have played the tutorial lol. Click on the bag of seeds and then the empty lot. You can buy more seeds at the shop if you run out.
