The arrival of winter, with the cold weather advancing and the wind stirring up the leaves in the garden, can affect the health and growth of your plants.
The animals that fill the garden with life in summer tend to diminish, hiding underground and among the branches of plants. Yet, their presence remains very important, especially if we aim to create a biodiverse garden – filled with all the wonders of nature.
In this article, we will discover together how to encourage the presence of useful animals during the winter and what elements to take into account in order to create a biodiverse and balanced vegetable garden. By the end of the reading, you will be ready to face the winter season and keep your garden’s productivity level intact.
Let’s get started!
What is a biodiverse vegetable garden?
Let’s start at the beginning, trying to give an effective definition to the term ‘biodiverse vegetable garden’.
In the world of agriculture, the biodiverse garden is nothing more than a type of garden designed and managed with the aim of maximising biological diversity within the cultivated environment. In fact, we are talking about an approach to cultivation that is based on the idea of creating and maintaining an agricultural ecosystem that imitates nature as much as possible, promoting the presence of plants, animals, insects and microorganisms.
In fact, the biodiverse garden focuses on the cultivation of a wide range of plant species, including horticultural plants, herbs, flowers, shrubs and trees. This plant diversity favours the attraction of an important number of pollinating insects and other beneficial organisms.
To attract insects, the biodiverse vegetable garden avoids the excessive use of chemicals such as pesticides and synthetic fertilisers, preferring instead natural and sustainable farming techniques that respect the ecological balance. Within the garden, areas that mimic natural habitats (such as hedges, woodpiles, areas of tall grass and rocks) are created to provide refuges for beneficial insects, birds, amphibians and other useful animals.
Practices such as crop rotation, composting and the use of ground covers are typical of the biodiverse garden. Throughout the year, the combination of these practices helps to maintain a high level of soil fertility and prevent dangerous plant diseases, while also reducing dependence on chemical fertilisers.
How to create a biodiverse vegetable garden step-by-step
How to create a vegetable garden that promotes biodiversity?
The ultimate goal of the biodiverse vegetable garden is to create an environment that is more resilient to environmental stresses such as disease, climate change and variations in weather conditions by harnessing the diversity of plants and organisms present.
Now that we have discovered what the biodiverse vegetable garden is and why it is chosen by growers, we can focus on creating it.
Through our step-by-step guide, you will soon be able to create a garden that takes care of plant health and builds a sufficiently balanced ecosystem.
Step 1: Planning and designing the garden
The first step is to evaluate the soil. Analyse the available soil to understand the relevant environmental conditions, such as sun exposure, soil type and drainage level.
Once the analysis is complete, choose a suitable area for the creation of the vegetable garden, preferably exposed to the sun for most of the day. Decide on the size and layout of the garden according to your space availability. Vertical vegetable gardens are many used in small gardens, as are potted gardens (we have discussed them here).
Step 2: Selecting plants
The choice of vegetable plants to grow is always very complex, especially since it is influenced by your tastes and the size of the vegetable garden itself. Generally speaking, herbs are always the first to enter the vegetable garden pattern, followed by leguminous plants (such as broad beans, chickpeas and beans) and green-leaved plants such as lettuce and spinach. Tomatoes, courgettes and aubergines are perfect for beginners, precisely because they are easy to grow and control.
When selecting crops, try to favour native plants and local varieties that are better adapted to the local environment and support biodiversity. In addition, plan the arrangement of plants to take advantage of associated cultivation, an agricultural approach that allows plants to benefit from each other’s proximity.
Step 3: Creating habitats for fauna
In biodiverse gardens, the integration of natural elements is always highly recommended. Add elements such as hedges, rocks, woodsheds, trees and artificial ponds to create natural habitats for insects, birds, amphibians and other useful animals.
At the same time, create insect shelters using natural materials such as logs, straw and rocks. These types of structures favour the presence of insects in the garden and the creation of a balanced ecosystem.
Step 4: Sustainable cultivation practices
As mentioned above, sustainable cultivation practices – e.g. crop rotation and the use of natural compost – help prevent garden diseases and maintain soil balance. In most cases, composting organic waste is sufficient to produce natural fertiliser and improve soil fertility.
Such activities, which are very common in biodiverse gardens, minimise the use of pesticides and chemical fertilisers, keeping soil health in check and promoting biodiversity.
Step 5: Maintenance and management
As always, no vegetable garden can hold its own without proper maintenance.
Observe your vegetable garden regularly to check for harmful insects, diseases or imbalances in the ecosystem. Only intervene when necessary, remembering to leave some areas uncultivated or with wild vegetation to encourage biodiversity.
At the same time, it would be best to rely on responsible irrigation techniques – such as drip irrigation – to conserve water and avoid any water wastage.
We have talked about useful insects and animals in the vegetable garden, explaining how crucial their presence can be for the creation of a sufficiently balanced ecosystem.
Let us now go into detail and discover together which insects are allies of the vegetable garden and which practices can help keep their presence in the garden under control even during the winter.
Which animals are useful for the health of the garden
Useful’ animals, which facilitate plant growth, are among the main ways of promoting biodiversity in the vegetable garden. These specific animals play an important role in maintaining the balance of the ecosystem, contributing to healthy plants and efficient production.
Let us take a look at some of the most useful animals for the health of the vegetable garden:
Bees are on the list of the most common and most important pollinating insects. Their presence favours the fertilisation of plants, increasing the yield and quality of fruit.
At the same time, butterflies and various other flying insects contribute to the polynisation of many plants, improving fruit and seed production;
- Natural predators of harmful insects:
Ladybirds feed on aphids and other plant-damaging insects, helping to control their populations. Similarly, Chrysops larvae feed on aphids, mites and other pests.
Finally, predatory insects such as mantis shrimps, pollinators and bark beetles consume a wide range of insects harmful to the garden;
Tits, robins and other insectivorous birds feed on insects, larvae and small invertebrates harmful to plants;
Frogs and toads feed on insects such as flies and mosquitoes, helping to control their populations;
Earthworms promote soil health through their digging process, improving soil structure and contributing to the decomposition of organic matter. Simultaneously, beneficial bacteria and fungi help decompose organic matter, making nutrients available for plants;
Hens, ducks and geese, in addition to providing eggs and meat, can contribute to insect control and soil fertilisation.
All these animals play a crucial role in the garden ecosystem, providing ecosystem services that help maintain the natural balance, reducing the presence of pests and contributing to the overall health of the plants and soil.
Useful practices to encourage the presence of insects in the garden
During winter, encouraging the presence of beneficial insects and animals can contribute to the formation of a balanced ecosystem in the vegetable garden. In the world of agriculture, insects can become excellent allies for the vegetable garden, you just need to find the most suitable species.
Here are some useful tips that will help you understand how to preserve biodiversity in vegetable crops in the winter season:
Start by creating protected areas where beneficial insects and animals can find shelter during the colder months. To achieve this, you can make use of piles of dry leaves, tree trunks or simply stacked rocks;
Perennials, such as certain types of herbs (rosemary, sage, etc.), can provide food and shelter for insects during the winter;
- Leave dead plants in the garden:
If possible, leave some dead plants standing during the winter. These plants can provide a valuable habitat for insects that feed on decaying wood;
Place feeders and distribute seeds, dried fruit or dried insects to provide food for birds during the colder months. As we have seen, birds can help control the population of harmful insects throughout the year;
- Limit the use of pesticides:
Try to minimise the use of pesticides during the winter, especially as they can harm useful insects still present in the garden;
- Monitor and maintain balance:
Carefully observe the vegetable garden and try to maintain a natural balance between harmful and beneficial insect populations. Human intervention should only be necessary if there is a serious imbalance that threatens plant health.
Together, these practices can help provide a welcoming environment for beneficial insects and animals during the winter, thus helping to maintain a balanced ecosystem in the vegetable garden.
The benefits of the biodiverse vegetable garden
What benefits does the biodiverse vegetable garden bring?
After looking at some useful tips for increasing biodiversity in the vegetable garden, let’s try to understand what benefits a biodiverse vegetable garden can actually bring to your crops.
Fortunately, the benefits go far beyond simply producing food. Let us look at them together:
- Disease and pest resistance:
Since the biodiverse vegetable garden attracts insects and natural predators that control harmful insect populations, the risk of plant diseases/infections is significantly reduced;
Plant diversity and the use of compost help improve soil health and structure, promoting a natural nutrient cycle;
- Reduced use of chemicals:
The biodiverse vegetable garden induces reduced use of synthetic pesticides and fertilisers, also decreasing the environmental impact and subsequent contamination of soil and water resources;
- Biodiversity conservation:
The biodiverse vegetable garden promotes the conservation of local and traditional varieties of plants, thus contributing to the preservation of biodiversity;
The integration of natural elements provide ideal habitats for insects, birds, amphibians and other animals, thus contributing to the biodiversity of the surrounding area and the vegetable garden itself;
The diversity of plants allows the vegetable garden to be more resilient to climatic fluctuations, protecting food production from extreme events such as drought or heavy rain;
Planting diverse plants leads to a wider range of nutrients in the produce grown, providing a richer and more nutritious diet. In fact, the biodiverse vegetable garden creates a healthier and more balanced environment for plants, animals and microorganisms, contributing to the overall health of the ecosystem.
In summary, the biodiverse garden not only provides direct benefits such as healthier and more abundant food, but also long-term benefits for the environment, biodiversity and the health of the ecosystem as a whole. The promotion of biodiversity and the sustainable management of natural resources are key elements that make it an ideal approach for agricultural cultivation.
Encouraging the presence of ‘good’ insects in winter is entirely possible. The biodiverse vegetable garden can help you achieve this goal and obtain an abundant harvest even in the cold season.
