Growing food at home is hardly a new idea. But in this culture, where more people know how to take the perfect selfie than how to grow a potato, urban agriculture has become a form of activism. The slogan “Food Not Lawns” is spreading like wildfire.
Here are some reasons why:
Lawns are the largest agricultural sector, covering more than 40 million acres of land and consuming more than 800 million gallons of fuel each year in the U.S. alone, according to Duke environmental professor William Chameides. The cost of organic produce is prohibitive for many families. Growing their own gives them access. Eating fresh produce improves health and increases vitality. Gardening brings a family closer together and sharing surplus produce, seeds and plants builds community with neighbors and fellow gardeners. Growing food creates a sense of empowerment and gives gardeners the feeling that they have control over their food supply.
These are just some of the ideas that sparked the Food Not Lawns movement. I started the original Food Not Lawns organization in 1999 in Eugene, Oregon. Three of us who cooked for the local Food Not Bombs chapter started calling ourselves Food Not Lawns and hosting workshops in our garden. Our vision was to share seeds and plants with our neighborhood, to promote local awareness about food security and to learn about permaculture, sustainability and organic gardening.
Within two years the project had expanded to include dozens of gardens around the neighborhood, and Food Not Lawns was rewarded with a Neighborhood Development Grant from the city of Eugene. From there, Food Not Lawns continued to blossom. Now, 16 years later, Food Not Lawns is an International network with more than 50 local chapters.
Here are some of the most frequently asked questions that I get from people who want to turn their lawns into gardens:
How do I get rid of the grass?
There are a few options, each with pros and cons:
Sheet mulching is a technique where you cover the grass with cardboard and then pile on organic matter — straw, leaves, food scraps, soil. It’s basically like building a wide, short compost pile all over the yard. The top layer is covered with fine mulch and then nursery plants and seeds can be planted directly into the mulch. This is the preferred method of most permaculture aficionados, as it is the least harmful to soil communities and can be a quick way to build up garden soil for growing food. However, sheet mulching can pose multiple problems.
If you have the kind of grass that spreads through underground rhizomes, there is a good chance those roots won’t die under the mulch, and will eventually create a hard-pack of thick roots that your plants won’t be able to penetrate. Also, the piles of un-composted materials can tie up nutrients and make it hard for your veggies to thrive.
Garden boxes, aka raised beds.
This can be a great way to build gardens quickly, while still maintaining paths and patches of your lawn. Spread a layer of landscape cloth or cardboard on the ground to suppress the grass, and then build boxes in any shape on top. Fill with organic garden soil and you’re ready to plant. This is a great technique for people who have back problems and prefer to garden in beds that are up off the ground. Problems with garden boxes include the continued growth of grass rhizomes, as I mentioned above with sheet mulching. Also, the soil in the boxes gets stale over time and will need to be replaced and/or amended. Garden boxes also tend to decay and fall apart over time, and will need to be repaired.
Roto-tilling (or hand-digging).
By far the most effective way for permanently removing your lawn is to dig off the top layer of grass and then till up the soil underneath. This presents a blank slate for designing your garden layout, and new plants will be able to send deep roots into the ground. Tilling can be problematic, however, if you have lots of rocks or toxic soil. Tilling also disrupts micro-communities in the soil, so it’s important to mulch over the new beds with good organic matter. Once you’ve tilled and established a garden, you probably won’t need to till again as long as you maintain the garden and keep the remnants of grass roots from re-establishing themselves.
Does it have to be in the front yard?
Of course not! In my opinion, the transformation of any lawn to a garden is always a good thing. However, growing food in the front yard becomes a statement to your community, telling them that you value homegrown food. Front yard gardens invite community dialogue, and bring fellow gardeners in the neighborhood out of the woodwork. Front yard gardens can also provoke complaints from the neighbors, however, so follow these four basic guidelines to help ensure those neighborly reactions are positive:
1. Be creative. Spend some time designing a garden that is beautiful and unique. Get some books on edible ornamentals and create a landscape people will see as a work of art.
2. Be consistent. Don’t let the front yard get overgrown and unsightly. Keep up with weeding, mulching and pruning. Be ruthless with dead and diseased plants. If your energy for gardening wanes, scale back your plans and only grow what you can maintain.
3. Be charitable. Offer surplus produce, plants and seeds to your neighbors. Invite them to share in the harvest and offer to help them with their garden ideas. Neighbors who value you as a friend are much less likely to cause problems.
4. Be considerate. Understand that not everyone in your neighborhood will be as excited about growing food as you are. Don’t leave piles of soil or cardboard in the driveway for weeks on end. Consider their needs and they will consider yours.
I’m overwhelmed! Do I have to rip out the whole lawn?
Not at all. In fact I recommend starting small. Remove a section of the lawn and plant a little bit of food or a herb spiral. Or remove the lawn around the edges and plant an edible hedge of raspberries and currants. Or just carve out a few circular spots and plant some peaches and figs. These small changes will provide a delicious inspiration for you and your neighbors, and when the time is right to take out the rest of the lawn, you’ll be ready!

At the end of the growing season last year, one of my volunteers remarked, “I think you have given us hundreds of dollars worth of vegetables this fall.” Indeed, growing your own garden often means that you are saving money on produce that would normally cost a lot of money in the grocery store, especially if it’s organic.
However, with the money you invest in compost, seeds, and plants each season, not to mention the time, sometimes the vegetables or fruit that you’re harvesting from your garden seem like they are worth their weight in gold. Granted, there are so many intangible benefits to having a garden and I would never give up gardening because the ‘numbers don’t pencil.’ But, it is also possible to grow delicious and healthy food without breaking the bank.
In my video below, I go over my Top Ten Tips for Gardening on a Budget. These are recommendations that I practice myself that not only allow you to save money but have the added benefit of building soil, conserving water, cutting down on pests, and creating a more ecological garden.

What is season extension?
In industrialised nations we have become used to being able to buy every type of fruit and vegetable all year round. When you grow your own, you quickly become aware of the limits to what you can grow in your area because of the seasonal nature of gardening.
Different crops are ready at different times of the year, with summer being the main season for the majority of crops. The further you are from the equator, and the higher your altitude, the shorter that precious summer season will be, and you may experience a hungry gap when few fresh vegetables are available.
A super simple cloche or cold frame can work wonders for extending the season. But truly, if you want to create a beautiful, productive, inspiring, and multifunctional space on your site, you simply must build a greenhouse. Whether it’s a tiny makeshift hothouse you can barely stand up in, or a hundred yard high tunnel filled with mature trees, a greenhouse will increase the diversity, yield, and enjoyment of just about any site.
Top ten reasons to build a greenhouse:
Start seeds early (and late!) Many seeds need warmth to germinate and develop into healthy seedlings. If the growing season is short, getting ahead can make a big difference.
Protect tender perennials and grow exotic plants. Increase your yields by extending the range of plants you can grow in your climate!
Protect early blooming fruits (like apricot) from heavy rains. Flowers on fruit trees are often quite delicate and can be damaged by rain, wind or frost, resulting in big losses to your fruit crop for that year. Choose dwarf varieties and plant them right inside the greenhouse.
Covered space for propagation and transplanting projects.Some plants respond well to a bit of nurturing, resulting in stronger, healthier plants. And gardeners also respond well to a warm place to work on a cold day! Choose a corner of your greenhouse to double as a potting shed and you’ll spend less time carrying seedling trays around.
Channel heat into your living space in winter. Build a lean-to greenhouse built against the sunny wall of your house and enjoy the extra warmth in the house.
Indoor/outdoor space for messy projects. Leave an open area in a section of a larger greenhouse and you’ll find that you use it all the time, for all sorts of projects.
Zen gardens! There is nothing like a high-ceiling greenhouse full of blooming, tropical, edible, aromatic, and succulent plants. Build your own mini-arboretum and escape to it when you’re feeling down. A mentor of mine even had a tiny office in his greenhouse, where she would go to get away from the family and write.
Secure medicinal and high-value plants. A well-built greenhouse with a locking door helps keep both animal and human marauders from making off with your crop.
Increased humidity for mushrooms, aquaculture. Some greenhouse designs include extra moist, dark, humid zones for cultivating edible mushrooms. Aquacultures also enjoy a more humid environment, and doing something inside a greenhouse could also allow you to add powered pumps, lights, and other features.
Guest housing! Sleeping in the greenhouse when it’s full of plants is the best!
You can plan space for propagation (seed starting) in a larger greenhouse, or build something intended especially for getting a jump start on the season. For convenience, or for simple ergonomics, this should be a bench or shelf. Extra lighting can be installed and/or heat mats are needed in more Northern climates. In temperate climates this may not be necessary.
Generally your greenhouse should be attached to your home or nearby, in your zone one area, because you will need (and want) to go there every day.
Larger greenhouses used for preservation crops such as tomatoes, peppers, or fruit trees, should be placed in zone two, unless it is more of a kitchen garden, then it should stay near the house. On a larger scale it is possible to have all three.
When a greenhouse is in constant use throughout the seasons, in particular if it is filled with more permanent perennial crops, other factors need to be considered year round:
When choosing or designing a greenhouse or polytunnel, it is important to ensure there are sufficient doors and windows that can be opened on warm days. It is surprising how quickly it can get really hot inside, often way too hot for both humans and plants!
On the other end of the spectrum, (unless your greenhouse is heated in winter) if you live somewhere with extreme cold, or if you have particularly delicate plants, more heat can be captured by insulating the greenhouse with a double wall plastic or glass. Recycled bubble wrap can be used for small areas, and combining techniques such as white walls, rock mulches, and even a cold frame or some cloches inside your greenhouse, can make a difference to whether your plants live or die.
If you live in a zone with high elevations, where winter weather sets in early and the permafrost levels go deep, the most energy efficient way to capture heat is by digging well below that permafrost level, preferably into a south facing hillside. Then, make raised beds within the greenhouse using compost.
For most homestead type greenhouses, raised beds are a good option for efficiency, either filling them with a good quality, bought compost, or ideally with your own homemade compost. I prefer French double dug beds integrated with high quality, on farm made biodynamic compost. Others prefer no-dig beds.
Another option for very cold zones is to put heat coils under the beds. These can be heated by either geothermal heat or via a closed loop hot water system fed by a solar hot water heater, wood boiler, or on demand water heater.
Airflow is very important for any greenhouse situation. Air flow is linked to temperature control. When the vents are open, air flow increases. But what happens on colder days when the doors need to be kept closed? Not only do plants need C02 for growth, they need airflow to prevent molds and fungus.
TIP: The biodynamic preparation called 508 can help regulate moisture and keeps fungus down in the soil. It is quite simply Equisetum arvense (field horsetail). This is an ancient plant full of silica. Pick in Spring, dry, add one ounce dried equisetum to four gallons of boiled water. Let this concentration cool then put it in a bucket and let it ferment for a week to four months. Strain off the plant material and store in a glass jar until use.
In my experience, the best greenhouses and polytunnels include a pond. This helps with pest control because it provides habitat for predators, e.g. frogs. It also improves the air quality, so may be part of the answer to the previous question.
Because greenhouses and polytunnels are confined spaces, it is possible to turn them into exclusion zones. For example, Alice Gray of Tyddyn Teg, North Wales, has excluded slugs from the farm’s extensive polytunnels. She did this by laying a strip of bran all around the inside edge of each polytunnel. As long as the bran stays dry, slugs are unable to cross it, and as she laid it inside the polytunnels, it does stay dry. Then she applied nematodes within each polytunnel. These ate all the slugs inside the polytunnels, so the polytunnels are more-or-less slug free.
The main disadvantage of greenhouses and polytunnels is that the rain can’t get in, so plants do need to be watered regularly. Doing this by hand may be time-consuming, but it does mean you get a close look at the plants while you are watering them and may spot problems early, such as pests or mineral deficiencies.
However, irrigation systems are very useful, and can be designed to use rain water gathered from the roof of the glasshouse or polytunnel, or can be part of a wider system of channels from a pond or dam. Whether you use overhead sprinklers or soil-level drip feed depends partly on what you are growing: For example, some plants are more vulnerable to moulds if their leaves get wet, especially within a humid glasshouse.
Soil & Fertility.
You can plant your greenhouse plants in pots on the ground, on tables, or on landscape cloth. Or you can just plant directly into the ground. As always, consider your soil’s needs, and make specific choices based on the geography and climate of your area.
Within a rotation system, fertility is managed at least partly by the different needs and gifts of different plant families. For example, the pea and bean family feed the soil via the nitrogen-fixing bacteria in their root nodules. When planting perennials, in particular within the confines of a glasshouse or polytunnel, it is worth putting some thought into this before planting.
Do some research into the needs and gifts of different perennials and companion planting. Mulching works well, but remember it may introduce or encourage the pests you have just excluded!
Here are a bunch of examples of greenhouses in use in the temperate Willamette Valley of Oregon. Here in zone 8, a simple greenhouse can extend the growing season by two months on either end and makes a huge difference in our annual yields.
If you need ideas and inspiration you could go find a greenhouse! This could be in your local park or botanic garden, or in a community garden or on a neighbour’s patch. Notice the differences between what is growing inside the green house and what is growing outside.
Re-visit the greenhouse at different times of the year, and in different weather conditions (e.g. on a warm sunny day and a cold wet day). What changes do you notice, both inside and outside the greenhouse? Talk to the gardener(s) and ask them what they value most about the greenhouse.
