Today in Plant ID class we discussed weeds. A weed is nothing but a plant out of place. Grass is a weed in your lettuce patch and lettuce is a weed in your lawn....
Generally weeds are strong/vigorous plants that have evolved to thrive in disrupted conditions.
Some reasons we remove weeds are:
- unattractive
- make harvesting your crop dificult
- Alleopathy- toxins from some plants have a negative effect on the desired crop.
- competition for light, water, nutrients and pollinators.
- harbour pest and disease-problem if crop and weed are related species
