Types Of Weedkiller Explained

Eradicating weeds from your garden seems like an endless task, but a necessary one that needs to be done in the most efficient way with least harm to the environment.

You can buy a wide range of weedkillers of all types to suit every situation from GardenSite. 

However, we regularly provide advice on weedkillers instore on this subject. Here of are your most frequently asked questions:

What time of the year is best to apply a weedkiller?

Although effective throughout the year, weedkillers work best when the weeds are actively growing from spring onwards. Dry conditions are preferable without any threat of rain for a considerable time following application.

How do Systemic Weedkillers work?

After applying systemic weedkiller to the plant's leaves it travels through the plant and into the roots. Although slower to take effect than contact weedkillers, a systemic weedkiller works by restricting the plant's ability to transport water and nutrients until the plant dies.

What is a Contact Weedkiller?

Contact weedkillers only kill the parts of the plant they come into contact with, ie the leaves and stem above ground. You may have to re-apply several times, as the weedkiller won't penetrate the plant's roots.

Are Systemic and Contact Weedkillers suitable for different types of plant?

As they invade the whole plant, including importantly the root system, systemic weedkillers are best used to eliminate deep rooted perennials such as dandelions. Contact weedkillers are excellent to deal with annual weeds.

What is a Selective Weedkiller?

Selective weedkillers are formulated to kill only particular weeds, mostly broadleaf which are often shaped like rosettes and found in lawns.

And Non-selective Weedkillers?

These are also called 'broad spectrum' herbicides and kill practically every plant they come into contact with.

Where do I use selective and non-selective weedkillers?

Selective weedkillers are most useful on lawns as they will kill broadleaf weeds but do not affect the grass. Use non-selective weedkillers on large areas that need to be cleared, drives and paths.

I'm uncomfortable about using chemicals, is there an organic alternative?

There are products such as vinegar and rock salt that provide an alternative, and many well known manufacturers are introducing organic products to augment their existing range.

Can you buy Organic Weedkillers?

For more information on organic weedkillers see our blog on 'Can Weedkillers Be Organic'.
