Disclosed is a plant protection device that combines the functionality of a solid walled style plant protector that is good for the establishment of a new plant/seedling and perforated style plant protector that is good for an established plant. The wall of a tree/plant protector and growth device has thin areas inherent in the wall that degrade faster than other parts of the same device wall. This occurs based on the weather conditions (wind/rain/cold), UV degradation, biodegradation, and other factors. Over time these areas open up, allowing air, sun light and other environmental elements to reach the plant/tree within the protector. Strategically placing the thinner areas allows for designs for different plant/tree species and applications. Applications for climatic regions—northern, aired, wetlands, etc. Other applications examples are reforestation, vineyards, windbreaks, etc. The degradation of the thin areas can be controlled by using different materials, UV stabilizer levels and other methods.
