What Types of Mulch Are Best for Insulating Plants During Winter?
Mulching is an effective way to protect plants from harsh winter conditions. The best types of mulch for insulating plants during winter include straw, shredded leaves, and wood chips. These materials help maintain soil temperature, retain moisture, and prevent frost heave, ensuring your plants survive the cold months.
