What are Garden Weeds?
There are basically three kinds of weeds in your garden: annuals and perennials and biennials. Annual weeds are annual and re-grow every year. These plants produce large seeds and long taproots.
Perennial weeds, on the other hand, are perennial and live for more than one year. Perennial weeds are not as easy to spot as annuals, but they are worth keeping an eye out for.
Biennials weeds, a biennial weed completes its growth in two years, storing food and producing leaves in the first year and producing fruits and seeds in the second year. Mainly found in untilled fields, pastures, and hedgerows that are not mowed, biennial weeds are frequently found in these areas.
Some weeds are beneficial, namely, the ones that can provide fertiliser, increase soil moisture and serve as a living mulch. They also attract beneficial insects and bugs to your garden.
On the other hand, most weeds compete with your plants for water, nutrients, and sunlight, causing them to die or grow slowly. Herbicides are a quick fix, but they won’t help prevent recurring weed problems.
Some common weeds like bindweed, and pigweed. (See further information below) can be troublesome if left to their own devices, but do not worry help is at hand.

Weed Type: Perennial/Annual
Docks (Rumex obtusifolius)
Docks (Rumex spp.) can be identified by their large leaves and unique seedheads. These plants are frequently found in gardens and are difficult to eliminate due to their very long tap roots. Their leaves are edible and may be used for herbal medicine and colouring.
Weed Type: Perennial
Crabgrass (Digitaria sanguinalis)
Crabgrass is a hard annual grass that appears low to the ground and has many stems. Despite its appearance of thick blades of grass, crabgrass frequently avoids being cut by lawn mowers because of its location ‘close’ to the ground. Other tough annual weeds are usually unable to survive in high-traffic areas, but crabgrass survives.
Weed Type: Annual
Pigweed (Amaranthus retroflexus)

Weed Type: Perennial
Scarlet Pimpernel (Anagallis arvensis)
Any well-maintained lawn rarely has to deal with a Scarlet Pimpernel infestation. The plants grow from seed but last only one year. The leaves resemble those of common chickweed, another annual but Anagallis arvensis ‘square’ stems and red flowers are very distinctive indeed.
