In the most simple terms: A weed is a plant, bush, shrub or tree growing where you don't want it to. They sprout anywhere. From small to large, weeds are everywhere.
Weeds can damage concrete and if left unchecked can damage walls and even your home. They can and will damage your flowers and take over your garden.
Controlling weeds is a perfectly natural thing to do, it helps to know a little about the kind of weed you want to get rid of, they fall into 3 main categories:
Annual weeds live only for one year. Their purpose is to grow and spread their seed as far and as much as possible. They do this with the help of the wind, people, insects & pets. Try to kill these weeds before the lay seed.
They will grow from seeds on any cultivated soil. Seeds can survive dormant for multiple years waiting to sprout when ideal conditions allow.
Annuals are relatively easy to kill and you can put them on your compost heap providing they don't have seeds.
Examples: chick weed, annual nettle, meadow grass & speed well.
Much hardier and tougher to kill. Perennial plants can live for multiple years, they survive the winter seasons by storing nutrients in their roots.
If you don't get rid of all the root it may grow back as a whole new weed.
Examples: stinging nettles, dandelions, ragwort & creeping thistle
Much tougher to remove and if left unchecked they can damage your property. Woody weeds like brambles, ivy & unwanted tree saplings.
Like other perennials you need to kill the whole root structure and stump to ensure they don't grow back.
When controlling weeds you can either use manual work or chemicals to get rid of the problem.
For annual weeds you should try to kill them before they manage to spread their seed, using a hoe or gardening knife to cut them out. Identifying your weed is key.
For perennials you should pull or dig out the entire weed with a spade. Ensure you get the whole root structure or it may regrow.
When controlling weeds manually, prevention is the best cure. If you have cultivated soil that isn't being used then cover it, mulch it or plant in it otherwise they will grow.
Most gardeners look to use chemicals to control their weeds. Please ensure you always read the label with gardening chemicals.
There are many household chemicals that you can use as weed killer. They are for the most part effective but they can damage your soil and may only temporarily kill your weeds.

Glyphosate is the worlds most used weed killer. It's used on farms and in gardens across the world. If used correctly it is one of the safest & strongest herbicides available.

Triclopyr is commonly used for control of woody plants, including poison ivy, as it works better than many other kinds of herbicides for that purpose. It is a selective herbicide unlike Glyphosate, which means it will not affect grasses.
This can be a desirable trait depending on the site. Along with glyphosate, it is one of the more common herbicides used to control non-native invasive plants during habitat restoration.
There are two forms available, an ester form, and an amine form. The ester is much more likely to volatilize and move when applied during warm or hot conditions, and its use is typically reserved for colder times of year.
