Indoor Cactus Care

Home and Garden Expert, Larry Pfarr says a cactus planter is a D-I-Y idea that’s popping up all over social media. He stopped by to share how easy and shared his tips on indoor cactus care.  

Light
Cactus need bright direct indoor light so place them near a south or west window.
That means pull back sheer curtains and let them bask in the sunlight.

Watering
When it comes to watering, they thrive on neglect.  Allow the soil to completely dry out before watering and never let the plant sit in a tray of water.   If you are unsure if your cactus needs water or not, wait several days or even a week before watering.  Less water is best as more plants die from over-watering vs. under-watering.  They will require a bit more water in the spring, summer and early fall.

Fertilizing
Fertilize once a month in late spring and summer at ½ the recommended amount.

Containers
It is really best to have a container with a drainage hole. If that’s not possible, then using the utmost care as to not over water.   Keep the container as small and shallow as possible.  Cactus have shallow root systems and don’t need a lot of space for the roots to grow.

Transplanting
Cactus can and should go years between transplanting.  When they do need to be transplanted, choose a container that is only about one inch larger than what the plant is currently in.   Always use cactus soil when transplanting.  Potting soil will retain too much water and can lead to the roots rotting.

Cactus + Succulents mixed together in the same container
Succulents tend to grow much faster than cactus.  If you are mixing the two together in the same container keep in mind that you will have to remove and transplant the succulents long before the cactus.
