Even if the snow and the cold weather keep falling on us, think again, spring has indeed arrived and it’s time to plan your vegetable garden for the summer! Yes, it’s time to start your seedlings and daydream about the tastes of good summer vegetables. When we start this adventure, we can quickly be dazed by the number of products available to us for gardening, encouraging us to overconsumption or use chemicals. In this article, I offer you ecological tips and discoveries for an organic, productive and healthy garden!
1. Recycle Your Household Items
The idea that you must buy everything new to start your seedlings is wrong. I personally find that it can become costly as a starting investment with no real benefit. I would suggest keeping containers throughout the year in anticipation of the gardening season. For example, plastic trays containing croissants, roast chicken or strawberries make excellent mini greenhouses to start with. Old yogurt cups or other small containers from the supermarket can also be used to plant seedlings; simply drill some holes for drainage and you’re set! I even suggest that you cut off plastic lids to create labels to identify your plants and maximize the value of your containers. I have also seen several techniques on blogs that use toilet paper rolls as a biodegradable seedling cups, why not?
2. 2. Use Compost as Fertilizer
Compost is a natural fertilizer with lots of benefits that allows you to ditch conventional chemical fertilizers. It can be used as a soil amendment or as a fertilizer for your vegetable garden by being spread on the soil in the spring or when planting. In both cases, your crops will benefit from the various nutrients and micro-organisms necessary for their growth. It will also improve the quality of the soil by eliminating diseases and optimizing drainage and/or water retention. You can buy it in stores, or make it yourself. You can also consult your city’s website, which often has dates in the spring and fall for free distribution of compost to residents. Psst! Many cities even offer free seedlings and plants!

3. Use Insect Frass
Insect frass is a natural fertilizer developed from the circular economy which revalorizes the waste resulting from insect cultivation. It is a kind of “manure (residual biomass) made up of insect droppings, but also carcasses, moults and uneaten food residues”. It can be mixed with soil when repotting or simply placed on the surface of your garden. It provides an ideal bacterial dominance for successful vegetable garden production, while not creating a phosphorus overload in the environment. A study by the Urban Agriculture Laboratory (AU/LAB) of the Université du Quebec à Montréal proved that “insect frass allows a total production twice as superior to a mixed fertilization treatment containing frass and at least three times superior compared to other treatments”. You can buy it from two Quebec companies that I love, which I listed below:
4. Adopt Biochar for a More Fertile Soil
Magnifique découverte que j’ai fait récemment en regardant un reportage à la Semaine Verte et qui m’a convaincu de l’essayer dans mon jardin cette année. « Le biochar est un amendement du sol issu de la pyrolyse de biomasse. Il est utilisé en agriculture pour augmenter la qualité des sols, et donc leur productivité ; il est également utilisé dans la lutte contre le réchauffement climatique comme solution de séquestration à long terme de carbone atmosphérique dans les sols ». Il est aussi issu de l’économie circulaire (yééé!) et produit à partir de résidus forestiers qui serait normalement inutilisés. Selon Suzanne Allaire, experte en biochar, il aide à structurer le sol et améliore sa rétention d’eau en période de sécheresse. Super pratique pour les pays chauds avec peu d’averses ou pour une fille comme moi qui néglige souvent l’arrosage! En retenant les nutriments et en nourrissant les bactéries, notre sol devient donc beaucoup plus fertile et vivant. Grâce à sa haute teneur en carbone, il reste beaucoup plus longtemps que le composte dans le sol et quand je dis beaucoup plus, on parle des années, voire des siècles! Ce n’est pas rien quand même! Vous pouvez vous procurer le biochar et son guide d’utilisation ici.
Happy gardening!
