acouple of months a go i got cutting of a succulent (i wish a i had a camera!@#$%^)it looks like a finger and has very small and not so sharp thorns. i pooted two fingers in the house and they hava stayed green and grown at least two inches. the ones outside havbe turned purple and dont fel as solid as a succulent (at least that is what i think). i water the ones outside for real once a week and mist them every other dya - it is very hot here! i even took them out so i could throw them out tbut i found several green shoots below the ground. so i replantted them. that was a couple of weeks ago and i am yet to see any of theose geen shoots breaking the ground. and the fingers still look so purple. what can i do to help them grow better??
