MarthaStewart.com features Holland as expert on protecting flowers from frost
MarthaStewart.com featured Lynne Holland, a University of Maine Cooperative Extension horticulture and social media professional, as an expert on how to protect flowers from frost to survive cold fronts. Light frost can destroy entire flower beds without the protection of barriers, such as old linens or frost blankets. Preemptive watering can also help protect plants. Holland said temperatures below 31 degrees are considered a freeze and below 26 degrees a hard freeze.
