Why Do People Paint Their Tree Trunks White?

by Burntchestnut

Recently I saw trees with the bottom of their trunks painted white. I did some research on the internet to find out why.

A FEW REASONS TREE TRUNKS ARE PAINTED WHITE:

~~ To make the tree more visible, and help prevent road traffic accidents at night on dimly lit streets. Utility poles are often painted white at the bottom, too.

~~ To give trees growing in a row a park-like appearance. Some people paint tree trucks white as well as fence posts, picket fences, planters, mailboxes, sheds, and other outside objects to make their yard appear clean and tidy.

~~ To keep rabbits from stripping the bark off young trees. Add a small amount of rabbit repellent to the paint.

More Reasons Tree Trunks are Painted White

 ~~ To prevent sunscald / sunburn. Too much hot sun shining onto a tree trunk every day will cause damage to the bark over time. Painting the tree trunk can prevent sun damage.

~~ To protect trunks if a larger tree is removed and no longer provides shade to a smaller tree, or if a large number of tree branches are cut off and the tree trunk is no longer shaded. Only the lower trunks are painted because the upper portion of the tree is protected by the foliage.

~~ To prevent the bark of a tree from splitting and cracking off. This can happen in colder climates  when there are freezing temperatures at night followed by a daytime thawing. The painted white trunk helps reflect sunlight during the day and keeps the tree warmer at night.

~~ To protect the bark of the tree from infestation by borer insects. These insects often attack trees with the weakest outer protection.  Paint the entire trunk, including dormant buds, and paint the trunk 2 inches below ground in case the soil settles.  The trunk of a potted tree should also be painted.

~~ To protect exposed limb stumps after cutting. The exposed areas can sunburn easily and also allow entry for insects and diseases.

~~ To help repel adult beetles and weevils, especially on young trees. Sun reflection off the paint should reduce insect movement across the painted zone.

WHAT TO USE TO PAINT TREE TRUNKS:

Make a mixture of 50% latex indoor paint or lime, and 50% water.  You do not need to use white paint; any light-colored paint will work.

Never use an oil based paint or exterior paint because these type of paints can harm the tree.

If you don't care for the look of white tree trunks, you can buy tree wrap or burlap.

You've solved one of life's great mysteries for me. I've always wondered. . . .

I never thought of sunburn! Or the other ways this surface that reflects sunlight protects the trees. Interesting article!

I always wondered about that. For protection it is necessary, but I do not like the look. It makes the eye follow the trees down the whole row and emphasis is on the ground.

I still prefer to think it is so you do not walk into the tree trunks when you are on the way home after drinking too much Ouzo or Raki. :)

The paint on the row of trees does look nice and gives the sense of a picket fence.

Wow I've seen this before and wondered why people paint their tree trunks white, now I know, thanks for solving this mystery, very cool.

I've never seen painted trees that I know of, but I'm glad I'm in the know in case I ever do!

The first time we saw tree trunks painted white in Greece we were surprised. When we asked we were told it was to protect the tree from insects but someone else said it was so you could see them when you had been drinking Ouzo.
