Rot-Resistant Woods
A few years ago, redwood was a big no-no for anyone who cared about the environment because venerable old-growth trees were laying down their lives to become lawn furniture. Today, redwood is a renewable resource, as millions of redwood seedlings are replanted every year-about five for every tree harvested. And cedar is an even better choice since it can be forested even more easily and quickly than redwood. Both native woods are naturally rot-resistant. They are good, reasonable, non-chemical alternatives to pressure-treated wood, but they are not totally care-free, and a deck made from either redwood or cedar will still require regular maintenance. Tropical Wood Alternatives
There are other rot-resistant woods that are just coming to the American market, including ipe (also known as ironwood) and cambara. These exotic woods will last for 2o years or more with just one preservative treatment. Ask to see certification of sustainable harvesting methods before you buy any tropical wood products.

PRESSURE TREATED WOOD, CEDAR, REDWOOD
Redwood has a natural resistance to decay due to its high levels of tannins and oils. This makes it highly resistant to rot and decay, which is why redwood is a popular choice for outdoor furniture and decking. However, like all wood, redwood can still decay over time if not properly maintained and protected from prolonged exposure to moisture.
Redwood, cypress, and cedar are termite and rot resistant. These are softwoods and may not last as long as hardwoods.
yes. the bark contains a high level of tannin, which keeps bugs out and keeps it from rotting.

Hemlock is not very rot resistant.
Spruce wood is generally not considered highly rot-resistant compared to other types of wood, such as cedar or redwood. It has a moderate durability rating and is susceptible to decay when exposed to moisture. To enhance its longevity, spruce should be treated with preservatives or used in conditions where it remains dry. Proper maintenance and finishing can also help protect it from rot.
They can grow to be the biggest trees in the world. To be precise, they can grow over 350 feet tall. They are also extremely bug and rot resistant trees.
Some types of wood that are known for being water-resistant include teak, cedar, redwood, and mahogany. These woods are naturally resistant to rot and decay due to their high levels of natural oils and tannins.
The best types of wood for fascia boards are typically cedar, redwood, and mahogany. These woods are durable, resistant to rot and decay, and can withstand exposure to the elements.
Red pine is one of the most used woods in the country. It is not naturally rot resistant, however, it can be protected and treated to ensure that is it can resist rot.
