About us

Campus Crops is a student run urban gardening initiative at McGill University's downtown campus. We want to grow food on campus, by students, for students. We have been running garden behind the School of Environment building at 3534 University since 2007. In 2009 we started a terrace garden behind the James Administration building. We're really excited to keep improving these two spaces, and need lots of helping hands for the summer ahead! Get in touch and get gardening!

Yes we can...


By Anarcho-Asperge and Celery Volanas

One of the great ironies of our times is that people who don’t know how to grow food can eat to their satisfaction all year long, while other people, who possess such knowledge but have no access to land, are unable to grow their own food and must live in a constant state of precariousness. It’s become common knowledge that the agrarian methods inherited from past agricultural revolutions are ravaging ecosystems and the land we rely on to feed ourselves. What people don’t necessarily know, however, is how the gigantic system controlling every step of production and transformation of food has also destroyed the lives and cultures of thousands of people and communities across the world. 



Although the main idea behind today’s agrarian practices dates from the mid 18th century, when open-field systems and sustenance agriculture started being replaced by enclosed lands and land ‘improvements’ (from the old French ‘en pros’, meaning ‘for profit’), the so-called ‘Green Revolution’ and later major agricultural ‘improvements’ accelerated the deleterious effects of our agricultural methods. High yielding varieties (HYVs), large-scale mechanization, inorganic fertilizers, pesticides and herbicides (all made from fossil fuels), and more recently GMOs (genetically modified organisms) and factory farming, have contributed or led to greater pollution, increased fossil fuel dependence, climate change, soil exhaustion, loss of biodiversity, and more. HYVs are an excellent example of an ‘improvement’ gone bad. HYVs necessitate more water and fertilizers than do crops suited to their local environment and are grown in sub-Saharan Africa, where water can be scarce and soil easily exhausted. The environment in which modern agriculture is pursued is not necessarily ideal; as a direct result of neglecting the original landscape and its capacities, the application of modern agricultural techniques in these environments is detrimental to the ecosystems.



The constants throughout the agricultural changes outlined above are the commoditization of food, a disregard of ecology, and the imperatives of the capitalist market, namely competition achieved through productivity and economic efficiency. When food (or anything else, really) becomes a commodity, what is grown, who grows it, how it’s grown, and even who gets it doesn’t matter anymore: food is reduced to its exchange-value and the aim switches from feeding people to maximizing profits and supplying demand (of course, only people with money or people part of a money economy count as ‘demand’ in the global market). In order to do this, input costs, like labor- and time-related costs, are reduced and outputs are boosted using some of the ‘competitive innovations’ mentioned above. For example, input costs could be reduced by lowering the workers’ salary or using strong herbicides instead of weeding. The outputs can be increased by using GMOs that store longer on the shelves, allowing for longer transport where the produce might sell at a higher price, or by planting cash crops, which are highly subsidized staple foods that can be sold abroad at a high price. Food is no longer just a sustaining element, rather, it is a source of profit.



The capitalist market economy is tied strongly to food and is tough to escape from, even as an individual. An average person, for example (as much as a person can be ‘average’), will need to eat. In order to do so, they can either 1) sell their labor power on the market, which makes their access to food (through access to jobs to get money) dependent on the market, or 2) grow their own food. If they decide to find a job, the resulting situation of depending on money to feed oneself is a problematic one for most people on the planet. ...So if they can’t buy the food, they should grow it! However, if they decide to grow their own food, they will need land, and land comes at a price. Even if they are able to get enough money together to purchase land, they must pay land taxes annually. In order to keep up with expenses, the farmer will have to abandon sustenance agriculture for market-oriented agriculture in order to make profit. This means they are dependent on the market. Because of their low competitiveness compared to big producers, independent farmers can almost never survive long before having to bow before some agri-business. HYVs, GMOs, and cash crops, along with their flock of inorganic chemicals, become the name of the game in order to stay competitive, otherwise someone else will take your place.




Obviously, something is not working. It seems strange that no one can have access to land for their own needs, unless they participate in the greater market and economy in order to keep their land. And what about the fact that we can’t decide what we grow, how we grow it and where it goes? Food security is not possible when access to food is inevitably mediated by the market. Food sovereignty is as important, if not more important, than food security. Giving communities the opportunity to grow their own food and have control over which crops and agricultural methods they use according to the local climate and needs would alleviate their forced dependence on the countries and corporations of the ever-great Western/dominant world. Maybe we should do this.

People are connected to the land in their lives and cultures, and food plays an important role. The capitalist economy undermines both the society and the environment that form its basis. Capitalism also alienates society from the environment, and is therefore a problem, not a solution. Food-related issues like racism and irresponsible use of ‘resources’ are however not unique to capitalism and have existed before its rise. Still, because it has been built upon and has historically thrived on aforementioned injustices, capitalism is a wall between us and potential solutions: it needs to go.

A Bit of Permaculture: Build your own herb spiral


This is 'modest'. You should be modest too.
A herb spiral is a design that makes use of gravity and sun position in order to create multiple ‘microclimates’ that can suit different types of herbs (or vegetable crops or flowers or medicinal plants or all of them, you decide) in a limited space. When water is poured at the top of the spiral, it drains down to the lower layers, creating a dry and sunny habitat at the top, a shady (or not, your choice) and humid zone at the bottom, and different degrees of habitats relative to sun exposure and height between those two extremes. It is normally built out of rocks, bricks or even glass bottles filled with earth that form the structure and retain heat absorbed during the day, reducing drastic temperature variations that could damage fragile herbs.

Aside from it to be compact and versatile, a great advantage of the herb spiral is its suitability for companion planting. This allows an easier integrated pest management, as pest repellant or predator-attracting plants that couldn’t be planted nearby in a level garden because of their different needs can now thrive close to each other. A herb spiral also eases water management, as plants preferring dry soil will be planted where the soil dries quickly, plants that like well-drained soil will live in a soil that will drain nicely even after a big rain, and plants that can grow in wet soil will rarely lack moisture.

How you do it

To build a spiral, first choose a site, about one or two meters wide (or smaller, if you want a small spiral, but this will limit the range of microclimates). It doesn’t matter if it’s on the soil or on a hard surface like concrete or asphalt. The site should receive plenty of sunlight in order to keep Mediterranean herbs (oregon, sage, rosemary, e.g.) happy. Avoid places where water tends to form puddles. If you can find a sunny spot close to the kitchen, it’s even better, as you won’t forget to take care of your spiral and will not be distracted on your way to your spiral (or back to your kitchen).

When you’ve found the right spot, start by laying cardboard and/or B&W newspapers on the ground. This will keep weeds from growing in your spiral. Then, mark the spiral. It can be circular or elliptic; that’s up to you. In order to make sure the microclimates will be in an ideal situation, it’s better to place the bottom end of the spiral towards the North, so the humid zones are the shadiest and do not lose too much water through evaporation.

Remember to clean the bottles beforehand. Plants have some
difficulty tolerating 'certain' substances.
Follow by outlining the shape of your spiral with the building materials you chose. You can build the walls to their full height and fill the spiral afterward, or you can fill it gradually while you raise the walls. For a typical 3 foot high spiral to have a nice slope, its center should be 3 feet off the ground. Cap the bottom end of the spiral with a rock in order to avoid run off, unless you want to make a pond at the bottom.

Some people infill the spiral with straw that they’ll let turn into compost, but most people prefer putting gravel to build the slope, adding the soil at the end, with sand or geotextile between both. Gravel makes a solid base and ensures good drainage, avoiding collapse and waterlogging. Different soil mixes can be added in the spiral to enhance the effect of the microclimates. For examples, the lowest part can be filled with topsoil and compost, making a rich soil that will keep water, the middle zone can be two parts soil and one part sand, for better drainage, and the top part can have gravel and even more sand mixed into the soil, so the soil will drain well. Don’t forget to add compost to the soil mix in order to provide nutrients to the plants. When the spiral is done, spray it with water and let it settle. Plant your herbs, veggie crops, flowers and medicinal plants the next day.

What should I plant in it?

Most herbs prefer dry climate, but there is of course a variety of plants that can be grown in a garden spiral. Plants that need a lot of spacing (room between neighboring plants) should be avoided, as a spiral is better used when well crowded.  You should also choose plants you like, as it is useless to grow exotic plants if you’re not planning on using them. Also make sure that neighboring plants make good companions, referring to companion planting guides. Finally, take into account the final height of the herbs you want to plant, as this will affect how much shade they’ll provide to other herbs (which may be a good thing, or not).

To help you prepare your spiral, here’s a non exhaustive list of herbs and their preferred soil type. Note that you must look for their sunlight requirements yourself, an important characteristic to take into account when planning their final disposition on the spiral.

Watering Tips: Because it's simple, yet not that much, though it's not so complicated, well it looks like it is at first, but it's not THAT hard to get the twist, you know


For the layperson, watering plants means pouring water over plants. Unfortunately, there’s much more to it and some inexperimented gardeners learn it the hard way.



Watering is done as needed, although more frequently for younger plants. As plants mature, mulched or not, their roots will be able to reach water deeper in the soil, and their foliage (with some exceptions) will shade the soil and reduce evaporation.

In general, mature crops need 1 to 3 inches of water per week, although water needs vary with the weather and the stage of growth of the plant (during fruit production, most crops will prefer to avoid drought and will need more water than usual in order to produce quality fruits). Therefore, it may not be necessary to water every day (containers may escape this rule, as they can’t hold as much water as the soil garden).

1. How can I know when it’s time to water?



An easy way to figure out if plants need water is to stick one’s finger in the soil, as deep as possible. For seedlings, stick your finger quite close to the plant; for mature plants, anywhere under the canopy should do. If the soil is moist or wet about 3 inches deep (i.e. if the soil is moist 3 inches deep and deeper, not if only moist 3 inches at the surface), big plants should do fine; for seedlings or maturing root crops, the soil should be moist at least 2 inches deep.

The same method can be used to know if one has watered enough. After watering, the soil should be wet at least as deep as one can reach with a finger. Be careful: the soil surface can look wet even though the water has only penetrated 1 inch deep in the soil. Shallow watering stimulates shallow rooting, which can make the difference between life and death for some crops during long drought events.

For soil gardens, you can also refer to this soil appearance table (which assumes you know what type of soil you have, which is something you should know anyway!).

The weather is also a good indicator. If it’s been hot and/or dry for the last few days, watering is probably needed. If it’s been quite cold and/or humid and/or rainy, watering may wait a few more days or more, depending on other conditions.

2. When should I water?


Watering in the morning provides plants with enough water to last through the day, which may prevent wilting or other ill effects of hot/dry weather. This also allows water to dry during the day, reducing risks of disease. Avoid watering in the middle of the day, as most of the water gets lost by evaporation. If watering at the end of the day, make sure that the plants will have time to dry before the night, otherwise they could develop fungal diseases.

3. Am I watering too much or not enough?


When overwatered, plants that elongate continuously, like tomato and squash, will favor stem and leaf production over fruit production.

All plants will also show signs of wilting if under or overwatered. Temporary wilting can occur on hot and dry days, but wilting caused by long-term under/overwatering will persist even after the plants have been watered and/or cooled.

Other symptoms of over or underwatering include curling leaves, yellowing leaves, falling leaves, falling flowers, etc. Evaluate the moisture of the soil (look or feel) to determine if the cause is overwatering (wet soil, maybe moss or mushrooms growing) or underwatering (dry soil, cracked or crusted).

If you overwatered, don’t water until the soil has dried enough (use the finger technique). Overwatering can carry nutrients in the soil deeper than the plants' root depth and cause nutrient deficiencies.

If you underwatered, make sure that you don’t stop watering when the surface of the soil looks wet: use your finger to make sure the water penetrates well into the soil. Underwatering causes shallow rooting. This makes plants weaker and more susceptible to drought as they can’t reach the water and nutrients available in deeper layers of soil.

4. How should I water?

As much as possible, try to water awkwardly.

Too much water pressure can cause the soil to compact and crust, which in turn will make it harder for water to penetrate the soil. Try to simulate a gentle rain by adjusting the pressure, angle, or height of the water source.

You also want to avoid adding too much water at the same time, which can cause run off (i.e. displacement of soil). This is especially important when watering small seedlings or where seeds have just been planted, as you may uproot the seedlings, displace the seeds, or bury them, which prevents proper germination and growth.


Cold water cools the plants, reducing transpiration and plant temperature (plants stop growing when it’s too hot). Ice-cold water may, on the other hand, shock the plant and not be of any help. Warm water can be used in early spring and late fall, since the soil is cooler at that time.

Treated water contains chlorine, which kills beneficial micro-organisms in the soil and may also repel macro-organisms (insects and worms, e.g.). If possible, let the water sit in an open container for 24h before watering, for chlorine to evaporate.



5. Avoid wetting the leaves

Wet leaves develop diseases easily, particularly fungal diseases and especially if they stay wet overnight. When watering, try to only wet the soil.



6. Mulch
Mulch has many benefits, including reducing water loss by evaporation. Many types of mulches can be used, the most common being straw (not hay, as it includes weed seeds), dead leaves, grass cuttings, and woodchips. Woodchips should only be used for trees, fruit bushes, perennials, and large, mature fruiting plants (e.g. tomato after flowering).

It is also possible to reduce the use of mulch by planting crops densely with similar crops or with companion plants, but this may not be possible at the seedling stage and can pose challenges for nutrient management. Mulching fast-growing crops with high demands in nitrogen is generally not recommended, as the decomposition of the mulch will reduce the amount of nitrogen available to the crop and slow its growth.


7. Supplementary tips for outdoors irrigation

For soil gardens, fill glass or plastic bottles with water and plant them upside down at the base of your plants (be careful not to damage the roots!). The water will seep slowly into the soil as the plants need it.

And try to have fun, like this person does... No. No, that's too much, actually. 

8. Watering and stage of growth

Plants are more sensitive to inadequate watering at some critical periods of development. If possible, according to the ‘rules’ of companion planting, those plants should be grouped together in the garden. For all crops, proper watering (no big fluctuations, no underwatering, no overwatering, no etc.) is essential during and 2-3 weeks before harvest, but some have other specific needs.

Vegetable: Critical period for water needs


Bean, lima: Pollination and pod development
Bean, snap: Pod enlargement
Broccoli: Head development
Cabbage Head: development
Carrot Root: enlargement
Cauliflower: Head development
Corn, sweet: Silking, tasseling, and ear development
Cucumber: Flowering and fruit development
Eggplant: Uniform supply from flowering through harvest
Melon: Fruit set and early development
Onion, dry: Bulb enlargement
Pea: Flowering and seed enlargement
Pepper: Uniform supply from flowering through harvest
Potato: Tuber set and tuber enlargement
Radish: Root enlargement
Squash: summer Bud development and flowering
Tomato: Uniform supply from flowering through harvest
Turnip: Root enlargement

Moisture fluctuation can also cause blossom end rot in tomatoes and fruit cracking in various fruits (including tomatoes) during fruit enlargement. 


You clearly don't want this in your garden. It's like... Shyamalan's The Happening, but worse. Well, you know what I mean...
