How to use

SHAKE WELL BEFORE USE. As good practice, we recommend wearing waterproof gloves and gardening footwear.

Freshly cut tree and shrub stumps

Cut the tree or shrub stem close to the ground in November to March, and thoroughly treat the cut surface of the stump as soon as possible after felling.

Use a paint brush to apply the diluted Roundup® Tree Stump Killer on to the cut stump. Ensure the whole cut surface is saturated, particularly around the edges and bark of the stump. Ensure the brush is thoroughly cleaned before and after use.

Standing trees

In November to March, use an axe to cut angled notches that completely penetrate the bark of standing trees. Cut at approximately knee height, one notch for trees up to 10 cm in diameter and use two or three notches in trees over 10 cm diameter.

Using a ¾ or 1 inch standard paint brush, apply 2 ml (thorough wetting of the inside of the notch) per 10 cm trunk diameter of neat Roundup® Tree Stump Killer to each cut.

Do not treat in the period of active sap flow in the spring/early summer.

Japanese Knotweed

Apply as a foliar spot application using a 2% solution (20 ml made up to 1 litre of water).

For best results apply when the plant is flowering (usually August/September) but before autumn dieback. Good coverage is essential. Spray the underside as well as the upper surface of the leaves. Repeat treatment may be necessary if regrowth appears.

If Japanese Knotweed is growing amongst wanted plants apply 5-10 ml of a 20% (200 ml Roundup® Tree Stump Killer made up to 1 litre of water) solution with water per stem. See pack for full instructions.

Keep children and pets away from treated areas until spray has dried.

Where to use

Controls annual weeds and most perennial. weeds and trees around the garden and on areas not intended to bear vegetation such as hard surfaces, patios, drives, tarmac, paths and gravel areas. Can be used to clean up weedy ground before planting vegetables, flowers, bushes and trees, and to renovate overgrown areas.

Direct spray away from ponds and other surface water bodies. Do not use on lawns or other wanted plants unless you want to kill them. Do not use under polythene or glass.

When to use

Apply as a foliar spray to weeds and saplings at any time when the weeds are actively growing and have adequate leaf area to absorb the spray.

Freshly cut tree stumps and standing trees should be treated from November to March to avoid the period of active sap flow in spring/early summer.

Avoid spraying when rain is imminent. Rain within 6 hours of spraying reduces effectiveness and repeat treatment may be necessary. Apply in calm conditions to avoid drift onto cultivated plants.

Leave weeds 7 days before digging or replanting, for the weedkiller to move to the roots.
