Roundup® Speed Ultra is a fast acting multi-purpose weedkiller for use on unwanted vegetation. It can be used to kill broad leaved weeds and grasses in paths, drives, patios, and around the bases of roses, ornamental shrubs and trees. Treated areas can be re-planted or re-seeded the day after treatment.
As good practice, we recommend wearing waterproof gloves and gardening footwear.
Repeat treatment if necessary after a minimum of 14 days where re-growth occurs.
Treat established weeds before the start of flowering. Spray nettles and ground elder when new leaves have unfolded fully in late spring.
Weeds may show first visible results within an hour of spraying, depending on weather conditions and the type of weed.
Keep children and pets away from treated areas until spray has dried.
Use to kill weeds on flower beds, borders, vegetable patches, around roses, shrubs, hedges, greenhouses and along fences. Ideal before cropping and ground clearance before cultivation.
Can be used to clean up weedy ground before planting vegetables, flowers, bushes and trees, and to renovate overgrown areas.
For the control of weeds around ornamental garden plants, trees and in areas not intended to bear vegetation.
Most effective when applied to newly established weeds or those less than 10–15 cm tall.
Do not direct spray or allow spray drift onto cultivated plants and lawn as this product destroys all green plant parts.
