I recently became the caretaker of these plants. They have not had much
sunlight and I am acclimating them back into full sun over the next few
weeks. I am keeping them under a mesh tarp to let them get diffuse sun
and I plan to put them into larger pots with some fertilizer (3-3-3). Is
there anything that you can help me with based by just looking at the
picture or do you see any thing I should change with my plan? I am
guessing they are mostly some form of Euphorbia erythraea forma
variegata but am not really sure.

Thank you for your time,

Rich,

Aside from the Opuntia which is the only cactus, the white ones are Euphorbia “Ammak” and the green ones are either the green version of “Ammak” or are probably Euphorbia trigona.

Depending on where you live they may need to be indoor. They are only hardy down around 32F, so we recommend them indoor in the SF Bay Area in the Winter.

Fast draining cactus soils for all of them. The cactus needs some good sun. The Euphorbias can handle light shade to full sun.

Do not fertilize a lot or these will grow into giant trees too quickly. Very little water – every 3 to 4 weeks should be fine, although more if it is sunny and hot.
