As my plants begin growing slowly each spring so do the weeds. Weeds are simply those plants that grow where they are not wanted. All are usually fast-growing. Many are invasive. They all compete for space, nutrients, moisture and light.
Weeds are capable of growing in almost any soil or site.
Actually, some cultivated plants can be considered as weeds in certain circumstances. This results in the appearance of many unwanted seedlings the following spring. Annual weeds complete their life cycle within one year. They set seed that germinates freely. Some will produce several generations in a single season.
