Ficus trees are a great addition to a garden, landscape or even the interior of a home or office. Even though ficus trees are not ultra high-maintenance, it is important to protect them from cold weather and frosts in order for them to thrive. Luckily, this is a simple process and only requires a couple of tools.
Bring the ficus tree indoors before a frost or very cold weather if it is in a planter pot, and place it in a sunny window. This is an ideal situation if your ficus tree is planted in a pot, but many people plant them in the garden for their landscape and won't be able to do this.
Anticipate the frost by not watering the ficus tree planted in the ground the day before the first frost may happen. Water will create an even more freezing effect on the ficus tree during a frost.
Cover the base of the tree with mulch, wood chips or leaves in a thick amount (at least 4 inches). This protects the roots.
Cover the top of the ficus tree in a large garbage or canvas bag, pulling it down below the base as much as possible. Cover as much of the treetop as you can, to protect it. Secure the garbage bag to the tree with a plant tie, wrapping the bag around the trunk.
Insulate the area around the base of the tree with an old blanket or sheets to protect the roots even more, tucking it tightly around the trunk.
Keep the ficus tree warm if from frost or freezing temperatures with heat from holiday lights or electric heaters. Ideally, use the larger light bulbs and carefully wrap the light strands around the ficus tree, decorating it for the holidays. When they are lit they will provide heat for the ficus tree. You can also use portable heaters, electric or gas. Place them close to the ficus trees, but not too close as they will burn. Keep them at least several feet away for safety's sake.
