It looks so simple. Steps 1, 2 and 3.
Unfortunately there are issues along the way sometimes. Wasps eat many Monarch caterpillars. Three year olds accidently step on squishy caterpillars. Leaves run out.
But those that make it sure turn out beautiful. We've had one make it this far. We have three more to go. All end up in the kitchen under a blob of bluetac. Why would they eat the leaf where a family member hangs and have him/her fall to the ground?
This is as close to a pet as we get these days.
They are rather high maintenance, but very worth it when they make it.
