Still, bear in mind that you should not give your plant too much water. Let your succulent absorb all the water first and when the soil feels dry, water it again using the soak and dry method.

‘The Soak And Dry Method’ – This is a very simple and easy way of watering your plants are succulent or cacti in nature. Here’s how it works…

Water until the soil around the succulent it soaked. Yes, fully wet.

It must be in both a well-draining pot and soil, that allows the water to drain and escape.

You then simply water the succulent when you find that the soil is bone dry, hence the name ‘soak and dry’.

You can keep your Crassula Muscosa in full sun, outside or inside, or partial shade and cool rooms since this succulent can thrive in both.
