Orlando had a hard freeze last night- sustained temperatures at or below 28- which can harm or kill even native vegetation. I put the sprinklers on last night b/f bed to cover the plants in ice, which will insulate them a bit. Turned them on again early this AM to warm the plants up. Some sprinkler heads were clogged due to frozen water. I haven't seen anything like this in many, many years. I hope i didn't lose any major trees or shrubs. The strawberry growers are freaking out...
