Weeds are the unwanted plants growing in fields. They compete with crops for sources such as space, light, and nutrients thereby causing crop plants to get less of all these sources which may hinder their growth. They reduce farm and forest productivity, invade crops, smother pastures, and in some cases can harm livestock. There are approximately 250,000 species of plants worldwide; of those, about 3% or 8000 species behave as weeds.
Weeds have a controversial nature. But to the agriculturist, they are plants that need to be controlled, economically and practically, to produce food, feed, and fiber for humans and animals. In this context, the negative impacts of weeds indirectly affect all living beings. High strength vinegar is used to kill the weed, Pull the weed from the roots and use a Cape Cod weeder, V-notch weeder, or soil knife to make removing weeds easier.
Types of Weeds
There are generally three types of common weed plants in regards to their growth characteristics. These include:
- Annual types: They germinate and spread by seed, having an average lifespan of one year. These include both winter and summer types. Winter annuals, like chickweed, germinate in late summer/early fall, go dormant in winter, and actively grow during spring. Summer annuals, such as lambs quarters, germinate in spring, grow throughout summer, and are gone with the arrival of cold weather.
- Biennial types: Biennial weeds complete their life cycle in two years, germinating and forming rosettes their first year and producing flowers and seeds their second year. Examples of these types include a bull thistle and garlic mustard.
- Perennial types: They return every year and normally produce long taproots in addition to seeds. These weeds, which include dandelions, plantain, and purple loosestrife, are the most difficult to control.
- Abundant seed production.
- Rapid population establishment.
- Long-term survival of buried seed.
- Adaptation for spread.
- Ability to occupy sites disturbed by human activities.
