Durable Corrugated Plastic Tree Guards for Agriculture & Park Protection

Protecting young trees from external threats is essential for agriculture.

Our corrugated tree protectors offer a simple yet effective solution to safeguard tender seedlings during their vulnerable early growth stages. These durable plastic tree tubes act as physical barriers, shielding delicate plants from harsh weather conditions, nibbling pests, and browsing animals that could otherwise stunt their development.

These corrugated tree protectors give your seedlings a better chance at establishing strong, healthy root systems and sturdy trunk growth from the outset. By minimizing environmental stressors, tree guards help ensure your new plantings can allocate more energy towards vigorous development.

How to choose the right plastic tree guards?

Choosing tree plastic guards for saplings is actually a very technical task. The commonly used sizes are 450mm, 600mm, and 900mm, and these three heights are the three most common used specifications for corrugated tree protectors for saplings. How should we choose this size? Let’s talk about it next.

When choosing plastic tree guards, many people believe that the higher the plastic tree circumference, the better, because only when it is high can the seedlings be fully protected. In fact, this idea is wrong because saplings require light, respiration, and gas exchange with the surrounding environment. If there is too much obstruction, it is easy to develop diseases. So choosing corrugated tree protectors is not about the higher the better, not about the more the better, but about being sufficient and easy to use.

The seedlings we just planted are at their most vulnerable stage.

How can we determine if this height is sufficient? The ground diameter of this seedling generally does not exceed 3cm, and the height of the entire seedling is only knee high. At this stage, we need to guard against very small animals such as rabbits and mice. Therefore, for this stage, a height of 450mm is just right. It is like a small fence, which can accurately reach about 40-50 centimeters above the junction of the roots and stems. Small animals cannot reach it, and the branches and leaves of the middle and upper parts of the seedling are completely unaffected by sunlight and ventilation. And for some shrubs’ seedlings and slower-growing tree species, this height can support them through the most fragile one or two years.

When the sapling grows to half a person’s height, its risk also changes.

It used to be just a threat from some little rabbits and mice, but now you may be facing wild dogs, sheep, or deer, whose feeding height is precisely 40-50 centimeters to 70-80 centimeters. If you haven’t removed the original tree shelter tubes, then you are completely exposing the middle branch of the tree to risk. And there is also a risk at this height, which is the wind. Its windward area is getting larger and larger. If a strong wind blows over, the tree trunk will shake violently, eventually causing the sapling to break. To avoid this situation, you need to replace the original plastic fence with a 600mm tree guard, which can effectively block animal feeding and reduce the swaying amplitude of the branches in the wind.

We also have plastic tree guards with a height of 900mm, which is actually quite special in terms of specifications.

It is not commonly used for residential greening and courtyard planting. But if the windbreak forest project in coastal areas, such as sea breeze, blows this sapling with salt spray for years, the water evaporation of this sapling will be very high. If there were no plastic tree guards to block it, the sea breeze would directly blow dry the trunk. At this point, the 900mm plastic tree guard is like putting a windproof coat on this sapling. When the wind speed drops and the humidity is maintained, the survival rate naturally increases. Furthermore, if there are large wildlife activities near the project where the tree is located, such as sika deer and roe deer, they are not at all polite when it comes to gnawing on tree bark. They must go up to 900mm to fully protect the entire trunk, and even the thickness of the board cannot be two millimeters. It must be paired with a 3mm or even 4mm board to stabilize.

Some people may say that I plant poplar and eucalyptus trees, which can grow one or two meters tall in a year. They grow very quickly. Can I just buy a 600mm one? If you need to protect this fast-growing sapling, you can still make do by buying a 600mm one to save costs. But if it is a slow-growing tree species, then you must match it according to the actual height step by step in order to be reasonable.

In addition to the height and thickness itself, attention should also be paid to the use of support piles.

Because corrugated tree guards also have a certain wind area when placed on the ground. If they are simply inserted into the soil, they can easily be uprooted on windy days, resulting in the seedlings not being protected properly and even being crushed, which is not worth the loss. So we reserved a gap for inserting stakes at the bottom of the plastic tree guards, and used matching stakes to directly penetrate the gap and nail it into the ground, so that the entire structure can stand steadily there.

The conclusion

Therefore, when choosing protective tree guards, we must choose the appropriate height based on the characteristics of the seedlings. Only by ensuring sufficient protection can the survival rate of the seedlings be guaranteed, and the energy required for later seedling repair and maintenance can be minimized.
