Weed Control around Trees & Shrubs

Long Lasting Garden Weed Control - Weed Killer Flower Beds, around Trees, Shrubs & Borders

ProGreen have a wide range of the best weed killers for flowers beds and gardens. Our products provide safe and long lasting weed control around trees, shrubs and ornamental borders. Typically, these products are applied in the winter months and can control both weeds present and those yet to germinate.

Weed control usually lasts for 3 to 6 months, keeping garden flowerbeds and amenity areas tidy in appearance and minimising the need for costly and time-consuming hand weeding. All of the products below are safe for trees and shrubs where they have been planted later than the previous spring.
Please consult individual product labels for safety to each specific species.

We have weed killer products which can be applied as granules and solid or liquid products which can be diluted with water and applied as a spray through a knapsack or boom sprayer.

What are the best Weed Killers for Flower Beds and around Trees?

Kerb Granules

  • Kerb Granules provides long lasting, residual weed control in flower beds and around trees and shrubs. Good at controlling both grasses and broad-leaf weeds
  • Effective control of autumn and spring germinating weeds. Usually applied between October to February
  • Easy to apply through the Kerb shaker pot, provided free with all Kerb orders. Safe formulation which requires no mixing and there is no risk of splashing
  • The industry choice for weed control around Christmas trees and in forestry situations
  • Can be used as a replacement to Ronstar 2G, which is no longer available
  • Best control is achieved when cool, moist conditions follow application
  • Kerb Granules are safe on a wide range of tree and shrub species, please see product label for a full list

Kerb Flo / Propyz

  • Kerb Flo Propyz has all the benefits of Kerb Granules and is an excellent choice for weed control in flower beds and around trees and shrubs
  • Liquid formulation, which can be applied via knapsack or boom sprayer for covering larger areas
  • Will control a broad spectrum of grasses and broad leaved weeds, this can be extended by tank mixing Kerb Flo with Flexidor

It is important to apply only one Propyzamide containing product per year. For a full list of the species to which Kerb products can be applied please see the relevant product label.

Pan Isoxaben / Flexidor

  • An effective weed killer safe for trees and shrubs. Controls a wide spectrum of broad leaved weeds
  • Can also be used around various fruiting plants, vines and hops. For a full list please check the product label
  • Flexidor is often used tank mixed with Kerb Flo, complimenting Kerb’s weed spectrum. Giving a more comprehensive range of weeds controlled. This combination gives similar control to the revoked herbicide ‘Casaron G’ which contained dichlobenil

Paradise / Chikara

  • Total weed control, both grasses and broad leaved weeds in flower and shrub beds
  • Best control is achieved when applied in spring before weeds have germinated

The best long lasting weed killer?

A very high level of weed control can be achieved when applying the above products in sequence. An Autumn application of Kerb Granules followed by either Paradise or Chikara in the Spring would give long lasting weed control around shrubs and trees.

Alternatively for areas where weeds are already growing; an Autumn application of Kerb Flo, tank mixed with Pan Isoxaben (or alternatively Flexidor) followed by a Spring application of Paradise or Chikara tank mixed with a glyphosate product would leave flower beds and areas around trees and shrubs weed free.
