This season's Euphorbia dulcis chameleon are not performing too well. The
stems are weak but tall, the leaves are pink at the bottom while all are
drooping or wilting at best. What is wrong with them?

They are about 18 inches tall at the moment, but to be honest they look a
pretty sorry sight! Would it be a good idea to cut them back to their base
to give them a second chance?

The soil is a very sandy with lots of organic matter in it to improve
nutrition and water retention. It can get water logged after a particularly
heavy down pour. Don't know if that will make any difference.
