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.
