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. |

1. A variable ventilation plant protector apparatus comprising:
a vertical support; a robust flexible sheet for circumscribing a living plant, the flexible sheet having a plurality of holes including a first row of holes and a second row of holes, the robust flexible sheet connecting to the vertical support; and a degradable covering for restricting an air flow through the plurality of holes, the degradable covering directly secured to the robust flexible sheet at both a first seam and a second seam; both the first seam and the second seam structured to degrade to remove portions of the degradable covering from restricting the air flow through portions of the plurality of holes; and the first seam extending parallel to the first row of holes, and the holes in the first row of holes located equidistant from the first seam; and the degradable covering having a first thickness at the first seam and a second thickness at the second seam,
wherein
the first thickness is greater than the second thickness,the second seam is structured to detach from the robust flexible sheet before the first seam detaches from the flexible sheet, anddetachment of the second seam from the robust flexible sheet removes the degradable covering from adjacent to the first row of holes.
