Common Types of Weeds Around Flowers

There’s no need to provide a detailed classification or try to mention all types of weeds out there. To understand the basics, all we need is to examine the list of the common types of weeds that are frequently found on our flower beds. Here are 7 most typical garden weeds:

Bindweed

Field bindweed is considered to be extremely persistent and difficult to control. This plant sprouts late in spring, and you can see it during the summer season.

Quackgrass

Quackgrass reproduces by seeds. You can kill this plant only by digging out its roots as soon as you see it or with some chemical weed killers. It grows very fast.

Canada thistle

This is a pretty aggressive weed that reproduces by whitish and seed. It is difficult to control Canada thistle because of its deep roots. So you’d better kill it very quickly.
