What makes this weed one of the most difficult ones to remove from your garden are its roots, which can go up to 14 ft deep in the soil. It’s good to use a powerful weed killer like glyphosate, to remove them since glyphosate attacks weeds right up to their roots to kill them.

2. Dandelions

While some dandelions may be good to look at, they may soon spread all over your garden and become a nuisance, if not removed at an early stage. The reasons they spread quickly are their deep roots and lightweight seeds, which easily float with the wind and settle down all over the garden.

3. Lamb’s Quarters

While it has an unusual name, much to our surprise it is the most commonly found weed all over the world. We must remove this weed immediately on spotting it, as it is very harmful to the growth of the other plants in your garden.

This is one of the fastest and randomly growing weeds, because of which it gets its unusual name. If there is even a single piece of this weed left in your garden, you may see a lot of them within a few weeks, that’s how fast they grow.

Creeping Charlie forms a waxy barrier that can grow thicker as the growing environment becomes hotter or drier, or both. Try using a weed growth preventer frequently and continuously for at least 6 months to ensure that this weed does not grow in your garden.
