I'm bundled up here in South Central Texas too! Heat running constantly and I even have a tower heater near me that I use off and on, lol. We aren't used to this.
I'm sorry about your plant loss and know how you feel. We've had lots of rain and little sunshine. Gets depressing. Maybe the rain helped protect some plant roots from freezing.
Though we live in Florida, my husband always orders pink grapefruit from Red Cooper in Texas every winter. They are so good. Hope the freeze doesn’t hurt that crop.
