Growing plants in difficult conditions, using various containers
Mini-greenhouses for container gardening. Part 2: Plastic bottles (Willem van Cotthem)
In Part 1, the transformation of yogurt pots into a mini-greenhouse was described (see former posting).
In this Part 2, the use of plastic bottles as containers for the production of tree seedlings will be described. Indeed these bottles also function as “mini-greenhouses” for the roots, because the seedling roots are thus fully protected against drought, limiting the volume of irrigation water in a considerable way (as if the seedlings were grown in a real “greenhouse”).
With a bit of imagination, a number of variants on growing tree seedlings in plastic bottles can be found. I am strongly convinced that this technique offers many advantages over the use of polybags in tree nurseries (see also my posting

It goes without saying that bottle reforestation is an interesting technique for large-scale projects in developing countries as it limits considerably the costs of seedling production and irrigation, both before (in the nursery) and after planting in the field. It guarantees also a higher survival rate of the planted trees, which again lowers the costs of the project.
