When ever possible we try to avoid using herbicides, however, there are time when it is neccessary. What follows is a guide to how we use herbicides to control ivy.
Ivy has a very thick, waxy cuticle which is very resistant to foliar applied (leaf wipe) herbicides. Glyphosate is the herbicide of choice which is found in such products as Roundup Pro Biactive.
For Maximum Effectiveness with Foliar Applications
Treating Mature 'Woody' Ivy
Thick woody trunks on Ivy should be treated in the dormant season, which is generally November to February. The ivy is cut at the base and Gylphosate is immediately applied with a brush. It is important to do it straight away as the ivy will seal the cut after 10 minutes, making Glyphosate absorption impossible.
Chemical Thinning
Concentrated Glyphosate is introduced straight into the ivy through a axe cut into the bark, still leaving the plant intact. A Spot gun with a solid stream nozzle is recommended and it is advisable to make a second cut under the first to catch any surplus herbicide.
Work out how many hatchet cuts are needed according to the diameter of the trunk and space them round the girth. e.g. trunk of 20cm diameter requires 2 cuts. Alternatively the concentrate can be introduced through an 8mm drill hole, about 40mm long, aimed slightly downwards and radially towards the centre of the stem.
We work for property developers, landlords, landscape architects, garden designers, local councils such as Camden and have many, many happy customers.
