Please Help! What type of Cactus is this and how do I take care of it?

Q: Hello,

I bought a Cactus for my wife about two years ago from a local home depot. For the life of me I dont know what kind it is and I dont know how to take care of it. Attached is a picture of the plant. My wife and I would be very happy if you could help us out and tell us what this thing is and how to take care of it.



Your cactus is most likely an Opuntia subulata monstrosa.

It looks like it needs more light, so try moving it closer to a west or
south facing window. It also looks like your potting soil is too rich,
with way too much organic material in it. Re-pot in a quality cactus
soil that does not have any “forest” product in it. If you can’t find
that locally mix two-thirds pumice or Perlite with one-third standard
potting soil. Do not add sand (it stays too wet). Water about every two
weeks during the summer, once a month in the winter. With better light
and soil your cactus should take off and grow into a cool lumpy mound
that looks like a “star-trek-ian Xmas tree” in a few years. O. subulata
is a very fast growing species and the monstrose mutation of it is too.

Good luck,
