Understanding how to select weed killer for the garden is crucial as it enables us to address specific problems effectively. Weed control demands tailored solutions depending on whether we're dealing with a vegetable garden, flower beds, turf, or unplanted areas like paths and patios.

Why use weed killers for Weed Control? 

Those passionate about gardening don't resort to weed killers without careful consideration, but sometimes it becomes necessary. For instance, to eliminate grass or moss that can create slippery pathways when wet, or to prevent weed growth in unplanted areas.

Weeds not only compete for nutrients, light, and space but also deprive our garden areas of essential water. 

While common garden techniques like mulching or using mature manure, as well as manual removal with tools like weeders and hoes, can mitigate the problem, weed killers offer an alternative solution. 

Types of weed killer and their mode of action:

Contact weed killers: These target the foliage of vegetation, leaving the root system intact. They're effective against annual weeds. 

Systemic weed killer: These are absorbed by the weed, eliminating both the foliage and roots. They inhibit photosynthesis and cell reproduction, acting primarily on the plant's internal system. Although slower, they're effective against perennials with rhizomatous systems. You could try our Rootblast Super Concentrated Weed Killer to help kill underlying roots in your garden.  

When and how to use weed killers?

Using weed killers requires careful consideration as incorrect dosage or application can harm desired plants. Always follow the manufacturer's instructions diligently. Weed killers are typically applied as below:

Post-Emergence Treatment: Applied after weeds have emerged from the soil.

Used before turf laying.

Consideration of weather conditions is vital. Temperature, rain, and light can impact weed killer effectiveness.

Dry weather spells cause the weeds growth to slow down or even stop. Applications should be made once the weather changes to be moister/rained so the weed killer systemic action can begin again.

Ideally don’t treat weeds if rain is due, apply after rain has stopped.

Light enhances the effectiveness of systemic weedkillers by increasing photosynthesis and growth, the active ingredient of the systemic product is pulled into the weeds circulation more easily. 

Understanding these factors ensures the correct use of weed killers for effective weed control in gardens.
