Tree Trunk ProtectorA tree trunk protector can be essential for new plants until they get established as older and larger plants. Once the bark has become stronger and more resilient to the elements I always use one. 
This young plant has died inside the plastic plant guard. The sides have collapsed and not allowed enough air inside. Also, the seedling has not been strong enough to push its way through the weight of the plastic, especially against the wind. This plant is thriving in its plastic tree protector. It has been able to get enough rain, sun and protection from wind, frost and predators to enable it to grow strong, straight and dense. A few of these were chocked with weeds inside the tree guard, the young plants had died as a result. These two plants were planted at the same time, both could have survived if they had been checked every few weeks. The plastic tree protector shown here is a favourite in Australia, it is also very easy to make yourself. 
You can see here a section of the road on the way to my supermarket where the landowner has planted these trees so as to provide privacy and a small windbreak from the road. Return from Tree Trunk Protector to Sustainable Gardening Tips home page
