Natural tips for an organic vegetable patch

Chemical treatments are increasingly being banned across the planet thanks to the increased awareness of people. Growing “organic” vegetables has become mainstream, much more today than the fad it once was. Just as organic greengrocers are commanding more and more clients, we simple gardeners also strive to convert our own vegetable patches to organic growing.

Here are our tips to get started on your organic vegetable patch!

Placing and location

Proper exposure is the first stepVegetable patch plants, like other plants, need water, sun, and nutrients to thrive. In the past, whatever was lacking was compensated with chemical products. Light is the first and foremost factor: choosing the right spot will ensure your plants get the light they need.

Most plant species require full sun. If you can, favor a garden plot that faces South for the Northern hemisphere or North for the Southern hemisphere. West is also good since it will always get strong afternoon sun. Keep a smaller portion of land in a shaded area, since some vegetables prefer cool shade instead. This includes spinach, lettuce and radish.

Natural green fertilizers

Green fertilizer helps a lot, here phacelia and white mustardTo make the soil richer, forget about chemical fertilizer. They kill the soil off in the in long run, so it’s better to rely on natural fertilizer that will promote microbial life. For a great many vegetables, it’s often recommended to add fertilizer to the plot in the Fall that precedes the sowing. Simply put, you would spread a thick layer of ripe, mature compost.

Other options include manure or green fertilizer. This works because some plants have the capacity to release nutrients into the soil: these are called “green manure”. Depending on the type of plants, it might be nitrogen, potassium or phosphorus. Moreover, they help structure the soil, breaking up clumps. And cutting them back provides for a very healthy mulch. In Spring, you’d sow Phacelia, white mustard or vetch, whereas come Fall, you’d go for clover or sainfoin for instance.

Another key trick is to swap your spade out for a broadfork! It’ll dramatically increase soil life and fertility.

Organic seeds

Organic and heirloom seedsThis is the starting point of any organic vegetable patch: grow veggies from organic seeds! The difference between organic and normal seeds is that the plants from which these seeds were grown were not treated with chemical products. If the parent plants required treatments, it’s certain the the offspring would also require treatments and pesticides to survive. Organic seeds naturally resist disease and pests better.

What’s best is to buy both organic AND heirloom seeds. This means that you can collect seeds from your own harvest year after year without needing to purchase new ones every year! Since each generation of plants adapts more and more to your own garden environment, they’ll get better and better at fighting off parasites as time goes on.

Non-fertile seeds are usually hybrids that result from the cross-pollination of two species. It’s easy to avoid them: in their name or label, the “F1 hybrid” code appears.

Companion planting

Companion planting is a key practiceTo avoid pesticides, plants must be provided with all they need to evolve and thrive in their environment. Some “friendly” plants help each other out and make your own work easier. Such plant combinations are called “companion plants” or “companion planting”. For instance, carrot and celery will protect leek against leek moth, a pest it is particularly vulnerable to.

The reverse is also true: leek will trigger more growth for celery, and will repel some of the pests that usually attack carrot. The carrot itself appears in a great many companion plant combinations. For instance, it also pairs very will with strawberry since it repels mites and keeps fungus away. Strawberry, on the other hand, will stimulate the growth of garlic!

There are a great many beneficial plant combinations in the vegetable patch. Read up about each plant you’re hoping to grow, it surely has a cohort of friends that will make growing it easier – but also enemies that will make growing it more difficult!

Natural treatments against pests

Pest control can be fully organic, tooHowever much work we put into it, there always comes a time when the vegetable patch falls prey to hordes of pests and diseases. Larva appear that nibble off leaves and seedlings, sap-sucking insects drain the power out of leaves and stems, colorful fungus destroy growth… long is the list of diseases and pests! Luck is with us: for each attacker, there are completely natural and organic defenses that can be set up.

You’ll have to dig deeper to learn more about each specific vegetable plant, but here are a few overarching guidelines:

  • Don’t crowd plants. Crowded growing beds favors spread of fungal diseases.
  • For the same reason, don’t water the leaves but try to apply water near the foot of the plant.
  • Use rainwater.
  • Apply stinging nettle tea to reinforce plants.

If pests still emerge, try out various types of mechanical traps, natural predators, organic treatments (made with soft soap), pheromone traps, plants that repel or attract pests…
