Milkweed in vase is wilting
When you raise the caterpillars, indoors, do
you put some water in the vase for the milkweed stem that they feed on and how often do you replace the stem? I have seven caterpillars on one large stem that I just started yesterday and it's wilting.
Yes, you put the stem in water. I would cut the stem a good inch or two and put it in fresh water right away. Then, every couple of days you can refresh the water and it the milkweed starts to wilt, cut the stem again. Hope this helps.
