Plants What? -weeds Damage: -valuable plants Difficulties: -grow quickly -produce hundreds of seeds -spread over long distances -remain for years -survive harsh climates		Plant pests are called weeds. Weeds, like dandelions, often grow where we plant our vegetables, trees and flowers. Weeds often steal space, sunlight, water and nutrients from vegetable gardens and flower beds. This prevents more valuable plants from growing properly. Weeds are difficult to get rid of because most grow quickly and reproduce in large numbers. A single weed produces hundreds of seeds. These seeds are spread over long distances by the wind or small animals. Seeds can remain in the soil for years and survive harsh climates. They sprout and take root when weather conditions become favourable.
