Watering Your Cactus Plant

Here are some tips on watering your cactus plant:

  • Water your cactus frequently during the growing seasons (spring and summer). Watering should be at least once a week during the hot season and water more if you notice the topsoil is very dry.
  • During late fall and winter, cactus are in their dormant state. They don’t need too much water. Only water them occasionally or when you notice the soil is completely dry.
  • Water the younger plants more than the older plants. This is because the growth rate of the younger plants is higher, therefore moisture will be needed for them to flourish and grow well.
  • If you are growing your cactus on the ground, try dipping a stick into the soil and see if the level of watering is completely saturated. If you are growing in a container or pot, check below the pot, and if you notice water dripping from the drainage pot that shows your cactus is completely watered.
  • The type of potting soil mix will determine how much you should water your cactus. Choose a good potting soil mix that is capable of draining even if there is excess water when your cactus has absorbed enough water.
  • You should also be careful about over-watering. Over-watering leads to the rotting of the root.

-The leaves will start curling up.

-The stems may droop and turn brown towards the base.

-The spines on your cactus may be turning brown and drying out as well.

-If a lot of its leaves have fallen off, your cactus is probably not getting enough moisture at its roots which is why it is wilting.

How do you take care of indoor cactus?

Cactus are succulents that grow in the soil and need a lot of water to survive. They thrive on heat and light. If you want to take care of your cactus, use these tips from David Gledhill from

1) Only give them what they need: Don't over-water or over-light your indoor cactus because this can cause root rot. Keep the soil moist but not soggy.

2) Provide a saucer or dish under the plant: The plant needs to have a saucer or dish that is filled with water to allow excess moisture to escape, so it doesn't pool around its base and cause root rot.
