More than 30,000 hectares of land are covered in plastic, a geometric labyrinth five times the size of Manhattan, where 3.5m tons of vegetables are produced every year from tomatoes to cucumbers, peppers to courgettes, aubergines to melons, enough to feed half a billion people and generate a turnover of more than 3bn euros.
Around a third of UK gardeners use pesticides, and our studies found that house sparrow numbers, for example, were nearly 40% lower in gardens where the pesticide metaldehyde was used. By reducing pesticide use, you can actively encourage birds back into your outdoor spaces, as they rely on invertebrates such as slugs and snails as natural prey.
Seedlings are ambitious and will germinate and start growing once pressed into damp soil, shooting toward the nearest light source. However, if they remain in small containers without natural light, they can become root-bound and leggy, eventually collapsing under their own weight.
Lots of pressure at this time of year, isn't there? All those pink cheeks and sweaty brows puffing their way around the park in dusted-down trainers; all those Botivo mocktails (delicious, for what it's worth) as we strive to self-improve during one of the most grisly months of the year. I've never really been one for resolutions, nor time-measured sobriety (amazing how having small children deflates one's desire to drink enough to conjure a hangover).
You are not alone: social media is full of claims that soaking banana skins in water makes a fertiliser that will give you bigger leaves and better blooms. The hack Put banana peels in a jar of water, leave them to sit, then pour the liquid on your plants. Bananas do contain potassium and small amounts of other nutrients. The snag is you have no idea how strong it is or what's missing.
Garden angelica, Angelica archangelica, belongs to the Apiaceae family, the same botanical group as carrots, celery, fennel, and parsley. Like its relatives, it produces a large, distinctively umbrella-shaped inflorescence, or flower cluster, called umbels. In its first year, the plant forms a lower mound of bright green leaves. In the second, a thick, hollow stem shoots upward and unfurls the broad green flower heads that resemble wild carrot or Queen Anne's Lace.
To an unimaginable eye, a seed looks inert. Yet they are packed with genetic information and biological processes poised to unfold. All it takes is the right configuration of signals and stimuli from the environment to let them know it's time to dare to grow.
The term "soil fatigue" or exhaustion refers to the condition that soil profiles take on when they've been heavily monocropped and untended. This soil is devoid of the microbial content that offers plants bioavailable food. It lacks the fungal and bacterial organisms that interact with plant nutrients.
"I've been with Syngenta for 28 years," Ramachandran says, noting that early travels across Canada shaped his passion for seed care. "What really stood out to me is seeing firsthand the passion, the resilience and the impact the growers made." Those experiences, combined with Canada's short growing season, continue to guide his work. "Everything that we have done... is around addressing those challenges, and how do we create solutions that are fit for purpose, for Canadian growers?"
As concepts such as "regenerative" and "biodynamic" continue to enter the mainstream coffee lexicon, scientists continue to literally dig into the soil to give them meaning. A recent peer-reviewed study from India's Western Ghats argues that one of the clearest signals of healthy, sustainable coffee farms lies in the ground itself, with organic coffee soils performing better than soils from conventional farms treated with synthetic inputs.
People grow asparagus from crowns because it shortens the long wait times for harvesting. From seed, you'll need to wait three years before harvesting asparagus. Some people consider that a waste of time. The tradeoff is that you can keep harvesting every spring for up to 15 years or more. If you plant crowns, you get a one-year jump on things. However, those crowns may have soil-borne diseases you don't know about, so there is a risk involved. Seeds remove that problem.
Late winter is when keen gardeners can get a little restless. The weather is still cold, and spring still feels far away. Thankfully, you don't need to wait until the weather warms to start your growing season. There are plenty of fruits and vegetables that can be started in the late winter, ready for a bountiful harvest in the coming months. Each of these plants needs unique care in order to thrive, but thankfully, I can guide you through exactly the right steps.
