Focus on… Weed management
THEY steal root space, light, water and nutrients from your fruit and vegetables. They can also harbour pests, diseases and viruses – it’s no wonder we’re constantly waging a war on weeds! But more of us want to ditch chemicals in favour of environmentally sound control methods. So how do we get results?
First, get to know your enemy – there are two main types of weed: those that attack from above ground, and those that strike from beneath the earth.
Annual weeds
These fecund plants thrive due to the ability to produce masses of seeds, and their short life cycles. Just one fat hen plant can yield 60,000 seeds, and these can remain dormant in the soil for 20 years. Annual weeds are often termed ‘ephemeral’, meaning they can complete more than one life cycle (germinate, grow, set seed and die) in a year. Good examples of these ‘life fast, die young’ plants are hairy bittercress and chickweed.
