With our recent 16 degree F winter temperatures, all of the cycas plants (sago palms) in the garden now have fried foliage. This foliage will not recover, but damage like this is fully expected in our climate, and not something that will damage the plants. Be sure to not remove the old damaged foliage this early, however, since cycads are programmed to shoot out new foliage 10-14 days after the old foliage is removed, and this is much too early for new foliage, with more cold weather likely on the way.
We like to remove the old foliage starting in mid-April, when it should be safe. As you can see in the second photo, the central crown is still in great shape, undamaged by the cold temperatures. We think the central crown is one of the most fascinating parts of a cycad, which shows its’ ancient lineage.
