Olive trees are evergreen plants. They need low temperatures during winter and many hours of sunlight in spring to blossom. Yet, frost damage may occur due to the extreme cold, especially if you have small trees in pots and containers. An easy way to protect them is to wrap the pot with an insulating material. You may already know how to protect plants from frost or how to care for a potted olive tree. Are you now ready to find out how to wrap an olive tree for winter and a little more advice to promote new growth

Why protect olive trees from frost

Olive trees are eternal and evergreen plants. However, they need some extra protection, especially during the winter months. Most olive trees can withstand severe frost up to -10 degrees Celsius, especially mature trees that are located to the ground.

Due to their small trunk, petite and young olive trees can tolerate winter cold up to -5 degrees Celsius. You guessed that right! That’s why you need to protect them from the winter frost. In both cases, you need to increase the tree’s hardiness by protecting it from cold weather

How to protect an olive tree from frost in the open ground

Olive trees like to be in a frost-free, dry climate to survive, especially if you want them fruiting. Thus, if you have trees in the open ground, they need winter protection. A way to protect them is to wrap them with a fleece plant jacket

    3. Tie the fleece layers in place with twine.

You can also use a winter cover. Just open the zipper of the cover now and then to prevent mould.

How to protect an olive tree from frost in a pot or container

Newly grown trees are usually kept in pots or containers. They are kept there until they grow up a bit to be transplanted to the ground or for decorative purposes. These trees need extra treatment to withstand winter conditions. Here are some things you can do:

1. Bring them indoors

Growing olive trees in pots and containers gives you the option to move them indoors. However, you need to be sure that the inside temperature isn’t dramatically different from the outside. When you decide to move it, you need to keep in mind that an olive tree likes cold. Moving it into a heated place can damage it. 

You can leave your potted plants outside until late September or early October. You should keep them indoors until late Spring (the beginning of May). However, these dates may vary depending on the weather of each region.

2. Wrap them with bubble wrap

If it isn’t possible to bring your potted trees inside, there’s another way to provide winter protection. You can cover the pots with wrapping plastic bubbles. It’s an insulating material that will prevent the cold from reaching the roots.

  1. Bring the pot as close as possible to a window to be benefitted from the house’s warmth and be protected from the weather. 
  2. Mulch the base of the tree to protect it from cold.
  3. Place pot feet to raise the pot off the floor to let the water drain away. 
  4. Wrap the pot in 2-3 layers of bubble wrap to keep frost away from the roots.
  5. Covet the branches and stems with horticultural fleece and hold it in place with clothes pegs.
  6. During the winter months, avoid watering a lot. Do it only if rain doesn’t reach the tree to prevent waterlogging the roots.
