Again, the amount of water for your succulents outdoors will also depend on your location and the humidity where you live. The hotter it is the more you’ll need to water and the more humid it is, the less you’ll need to water. I generally water my plants every 2-3 days during the heat of the summer. However, during winter i will water them a lot lesser. When it does start cooling off I cut back to watering once a week and sometimes every other week.
