Mon potager dans des bouteilles en plastique / My vegetable garden in plastic bottles

Mes expériences avec des légumes poussant dans des bouteilles en plastique ont été très convaincants jusqu’à ce jour. Non seulement toutes les espèces se sont bien développées (sauf le chou-fleur qui a été infecté), mais je suis de plus en plus convaincu que cette méthode de jardinage peut être une contribution significative dans la lutte contre la désertification, la faim et la polllution de l’environnement (moins de plastique dans nos déchets). C’est une excellente pratique dans le domaine du “jardinage dans le désert“.

Afin de motiver un grand nombre de personnes à faire des essais pareils avec des légumes de leur choix (ou d’autres plantes), je vous montre quelques dessins et images. Je vous souhaite déjà beaucoup de plaisir et des observations intéressantes. Vous m’envoyez un petit rapport (si possible avec photos) ?

My experiments on growing vegetables in plastic bottles have been very convincing up to now. Not only all the species showed a good development (except for the cauliflower which was infected), but I am more and more convinced that this gardening method can be a significant contribution to the combat of desertification, hunger and pollution of the environment (less plastic in the household waste). It can efficiently be used for “desert gardening“.

In order to motivate a large number of people to set up similar trials with their choice of vegetables (or other plants), I bring you some drawings and pictures. Wishing you a lot a pleasure and interesting observations. Will you send me a small report (if possible with some photos) ?

    Hi,
    this is amazing, I had worked today in my small garden outside. I ran out of space and I still have seedlings, tomorrow first thing in the morning I’m going to try this experiment.
    I’m glad I looked at Bobs 34cents blog today and saw your comment, that made me get here.
    Fantastic, will keep my results posted here and on Africa54.

    I have used plastic bottle as mini greenhouses for years but never thoguth of gardens in bottles. Great idea!

    In pursuing your link to Lasagna Gardening, I came across the link below.
    I believe it contains a significant addition to your bottle gardens, and adds a whole dimension. I particularly refer to the partial burying of bottles of water next to plants to act as drip watering cans. [They have pin holes in them.]
    Combining the polymers and these bottles, gardeners can hopefully go on trips and come back after hopefully a week or more without crop damage.

    Now that I think of it, I guess it could be a challenge to combine getting the water in the watering bottles into a plant that is in a bottle.

    Also, I have drunk out of some plastic bottles that have been in the sun and there is some kind of chemical released into the water after being in the sun. Toxic and unpleasant.

    Hopefully, by painting the bottles one can avoid this, and if with light colored paint, the temperature may be lower considerably when in the sun.

    [The best of the new acrylic paints will hold up MUCH, MUCH better than older paints.]

    Anyway, partially or almost wholly burying the bottles next to plants is another use of your principle, if not directly holding plants, then acting as an easily made drip system. I believe it avoids much more evaporation than drip system, as the water is released underground.

    Potential challenges could include clogging of the holes, and possible release of toxins as a result of the sun.

    Article referenced above-

    TOMATOES

    …I prepare my site by installing water jugs buried up to their shoulders between where every two plants will be. A pin hole in the sides facing the plants should let enough seep out to keep up consistent watering. I place a tall stick in each jug, its top colored with red paint or nail polish. This helps me find the sticks, which helps me find the openings to the jugs when all the foliage hides them from view. I fill the jugs with a funnel and the water hose. You can add liquid plant food to the water if you like.

    Planting and harvest. Wait until after the last frost, then plant the seedlings. Create a well of soil around the stem to help catch any rain. If you have prepared the lasagna bed in advance, all you will have to do is scrape the soil aside and lay the plant down up to the last four leaves. Press the soil around the plant to make direct contact and push out any air pockets.

    Once the jugs and plants are in place, make a collar of one or two sheets of wet newspaper, place it around the stem, and cover the paper with mulch….

    What purpose does the cut-off top of bottle play when put in bottom and covered with top/potting soil. I have seen it in bottle the opposite way with a wick in the neck so water could be drawn up from bottom of bottle.
