WHAT ARE RHODODENDRONS?
Rhododendrons are spectacular flowers usually sprouting in the spring with autumn colour.
WHY ARE THEY A PROBLEM?
Impacts: Rhododendrons form very dense thickets and deprive other plants of resources and importantly sunlight. Other impacts on fish and invertebrate communities have been recorded. Rhododendron can also prevent access to sites by the shear mass of plant material blocking paths and right of way.
HOW DO YOU REMOVE RHODODENDRONS?
Method 1 – Herbicide Application.
Cut the bush down to as near as the ground as possible and the apply herbicide to freshly cut area.
Method 2 – Mechanical removal.
The stumps can be removed mechanically if you do not wish them to remain in the ground. Rhododendron does not have a tap root but the fibrous root plate is extensive. Winches and mechanical diggers can be useful.
Physical removal is the best method for small bushes. Plants up to a metre in height can be quite easily removed physically. Providing that the entire stem is removed, the plant will not grow back from the roots.
