KIMBERCOTE COMMUNITY GARDEN
REDUCING CARBON THROUGH RENGENERATIVE AGRICULTURE EDUCATION
Environmental Stewardship is defined as the informed and responsible actions and behaviours required to ensure that environmental quality is maintained locally, regionally, and globally.
We believe that this is a journey, and we adjust our objectives as campuses evolve, as funding is identified, and as science and technology provide new opportunities. We aim to increase our commitment to incorporating environmental stewardship into our decision making and behaviour systems, with the intent of being Carbon Positive by April 22, 2034.
This garden project was made possible by TD Friends of the Environment.
HUGEL MOUNDS
A Permaculture Powerhouse
Hugel mounds, also known as hügelkultur (German for “hill culture”), are a permaculture gardening technique that transforms organic debris into fertile, water-retentive growing spaces. At their core, hugel mounds mimic natural forest floor processes, where decaying wood and organic matter decompose over time, enriching the soil and supporting robust plant growth.
To create a hugel mound, a base layer of large logs, branches, or other woody material is laid on the ground. This is topped with smaller twigs, compost, leaves, grass clippings, or other biodegradable materials. The final layers consist of nutrient-rich topsoil and a mulch covering to protect the mound. Over time, the organic matter within the mound decomposes, gradually releasing nutrients and creating a sponge-like structure that retains water, reducing the need for irrigation.
Hugel mounds offer several benefits for gardeners and the environment. Their layered design promotes biodiversity by creating microhabitats for beneficial soil organisms and insects. The gradual decomposition of wood generates heat, extending the growing season in colder climates. Additionally, the mounds improve soil structure and drainage, making them ideal for areas with poor or compacted soil.
These mounds can be tailored in size and shape to fit different garden spaces, from small backyard plots to larger permaculture systems. By turning waste materials into a thriving garden bed, hugel mounds are a sustainable and efficient way to grow food while nurturing the environment.
MULCHING
A Core Permaculture Technique for Healthy Gardens
Mulching is a simple yet powerful permaculture technique that involves covering the soil around plants with organic or inorganic materials. This practice mimics natural ecosystems, where fallen leaves and organic debris create a protective layer over the ground, promoting soil health and plant growth.
In a permaculture context, organic mulches—such as straw, wood chips, grass clippings, leaves, or compost—are most commonly used because they decompose over time, enriching the soil with nutrients. These materials create a living mulch that supports beneficial microbes, fungi, and earthworms, all essential for building fertile, healthy soil.
The benefits of mulching extend far beyond soil enrichment. Mulch acts as a protective barrier, reducing water evaporation and maintaining consistent soil moisture levels, which decreases the need for frequent watering. It also suppresses weeds by blocking sunlight, minimizing competition for resources around plants. During hot weather, mulch regulates soil temperature, preventing roots from overheating, while in cooler months, it provides insulation to protect roots from frost.
Additionally, mulch prevents soil erosion by reducing the impact of heavy rain and wind, keeping the garden beds intact. Over time, organic mulch decomposes, improving soil structure and increasing its ability to retain water and nutrients.
Proper mulching involves placing a layer of 2–4 inches around plants, avoiding direct contact with stems to prevent rot. By integrating mulching into garden care, permaculture gardeners create a sustainable, low-maintenance system that fosters thriving, resilient plants and ecosystems.
the benefits of rainwater collection for gardens and the environment
Rainwater collection is an eco-friendly practice that captures and stores rain for later use, offering significant benefits for gardens and the environment. This sustainable technique reduces reliance on municipal water systems while providing plants with naturally soft, chemical-free hydration.
For gardens, rainwater is a superior resource. Unlike tap water, it’s free of chlorine, fluoride, and other chemicals that can build up in soil over time. Plants absorb rainwater more easily, promoting healthier growth. Using rainwater for irrigation during dry spells ensures consistent soil moisture, reducing plant stress and boosting yields in vegetable gardens. Collected rainwater is also ideal for tasks like washing tools or cleaning patios, reducing overall water demand.
Environmentally, rainwater harvesting helps mitigate urban runoff. By capturing rain that would otherwise flow into storm drains, it reduces the burden on municipal systems, minimizing erosion, flooding, and the pollution of waterways. In regions prone to drought or water restrictions, this practice offers a sustainable way to maintain gardens without depleting precious resources.
Setting up a rainwater collection system can be as simple as placing a rain barrel beneath a downspout or as advanced as installing cisterns with filtration systems for large-scale irrigation. By incorporating this practice, gardeners save money on water bills, reduce their environmental footprint, and contribute to water conservation. Rainwater collection exemplifies how small, thoughtful changes can lead to a greener, more sustainable future for gardens and beyond.
GROWING STAPLE CROPS IN GARDENS FOR FOOD SECURITY
Growing staple crops in home gardens is a practical and rewarding way to enhance food security. Staple crops—such as potatoes, beans, corn, wheat, and root vegetables—are calorie-dense and nutrient-rich, making them essential for meeting dietary needs. By cultivating these crops, gardeners can reduce reliance on store-bought food, mitigate the impact of supply chain disruptions, and increase self-sufficiency.
Staple crops thrive in diverse climates and garden setups. For instance, potatoes and sweet potatoes grow well in small spaces or containers, while beans and peas add nitrogen to the soil, supporting companion plants. Corn and grains like quinoa or amaranth are versatile options for larger plots, and root crops like carrots, beets, and turnips store well, making them ideal for long-term use.
Cultivating staple crops also promotes sustainable practices. Homegrown food reduces the carbon footprint associated with transporting and packaging commercial produce. Additionally, gardeners can use organic methods, such as composting and crop rotation, to maintain soil health and biodiversity, ensuring long-term productivity.
Beyond practical benefits, growing staple crops fosters resilience and community. Sharing surplus harvests with neighbors or exchanging seeds builds local food networks and strengthens social bonds. It also provides an educational opportunity for families to learn about food systems and sustainable agriculture.
In uncertain times, planting staple crops empowers gardeners to take control of their food supply, ensuring reliable access to nutritious, homegrown produce while contributing to a more sustainable future.
