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.
Southern California, especially Los Angeles, has many breathtaking botanical gardens and wildflower-lined hiking trails. But it's also exciting to visit private home gardens that are rarely open to the public and find inspiration even if you don't have space for a garden at home.
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.
Instead of running to the store every time you need a handful of fresh basil (and inevitably letting the rest go to waste in your fridge), having an herb garden of your own allows you to only take what you need. While this in itself is a great sustainable practice, try taking it a step further by starting an herb garden in old plastic fruit containers.
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.
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.
Onions may not be the prettiest vegetable to grow, but they're certainly one of the most useful. Figuring which items you eat most often is the first thing to consider before planting a vegetable garden, and as a fundamental part of soups, sauces, and salads, who couldn't use more of these easy-to-grow alliums? The only tricky part is that location really matters, as different varieties of onions require different day lengths in order to thrive.
The U.S. Department of Agriculture published the Plant Hardiness Zone Map, which breaks the country into 13 zones that help determine the best time of year to get started on various fruits and vegetables, such as peppers. Each zone varies by 10 degrees, and each subzone varies by five degrees, even if a single state can technically be broken into several zones.
