Annual weeds
The aim of annual weeds is to grow and set seed as quickly as possible. They grow from seed on any recently cultivated soil. Seeds can survive for years in the soil, waiting for the perfect conditions to grow. They germinate at lower temperatures than most garden plants, giving them a head start over rivals!
Controlling annual weeds is relatively easy:
  • The trick is to recognise them at the seedling stage, so you can get on top of them without accidentally eliminating flower or vegetable seedlings.
  • Most hoe or pull out easily even when they reach a good size. Put them on your compost heap, so long as they don’t have seed-heads.
