Now that winter is heading our way, it is now time to heavily mulch if you have not already done so. During a cold front, radiant heat from the mulch could bring up the temperature 1- 2 degress F. Most importantly it helps insulate the roots and keep them warmer. We have witnessed so croton cultivars that were freeze burnt to the ground that made a come back because they were heavily mulched. Their roots and enough of a below ground stem survived that it could regenerate. Yes, the Glocks are heavily mulching with the holiday social upcoming. They would have mulched anyways, they know its benefits.
