Succulents are so easy!
Spritz with water when they look dry! They don’t need much. When I lived in New Mexico I made the mistake of overwatering cacti.
There are lots of apps out there now to download that can identify your plant and give advice on what the plant needs. I recommend Googling some services!
You can thoroughly water when the soil is completely dry and then allow excess water to drain away about once a month or every three weeks.
Reduce watering in winter because succulents go dormant.
Signs of under watering: Wrinkled or dry leaves. Discolorations
