Identifying Cactus


Hello,
I found your blog online and it had been very helpful to me. I am really grateful that you answer questions from people that are not your customers, as well! I recently got a pot with three small cactuses in it and am having trouble identifying them. I have attached a few photos. For reference, the center cactus is about 2″ tall. What do you think? I am particularly curious about the one on the right as I can’t find anything similar searching online. I would like to know about their care requirements and if they are suitable to continue growing in the same container.

Thank you,
Regina

PS – I am aware that the l little red flowers on the center cactus are fake. I’ll remove them eventually…

Regina,

The left is a Mammillaria and the right is a Euphorbia (probably E. meloformis) while the one in the center, after the paper flowers are removed, is maybe a Myrtillocactus although it can be hard to be sure when they are young.

They can grow together in that container for a couple years and then they will outgrow it and need to be separated. Care depends on where you live, but the 2 cacti need a lot of direct sun – at least half day, while the Euphorbia is less. Not a lot of water, but the watering depends on whether the pot has a hole. Either way, make sure the soil is dry between watering, probably every 2-3 weeks.

Peter
