This week, hands-on workshop was devoted to gardening in the “lasagna method”. This technique enriches poor soil through organic gardening, and involves reusing waste such as cardboard, cut branches and leftover vegetables from the market, and use them in layers on the plot to grow: from the least decomposed on the bottom to the more decomposed on the uppermost layer. This allows for a highly nutritious substrate that can reconstruct the humus soil and avoid, by smothering weeds, the bulk of the weeding. We can even install a vegetable garden where there is no land on the concrete.
On this occasion three lasagna were carried out, one in the educational garden, and the other two on the Agrolab. The stack of layers followed this order: thick cardboard, twigs, dried grasses (in our case the result of weeding the garden), green waste market, shredded paper and cardboard, compost, enriched earth and vermicompost.
We have directly planted tomato plants, squash, pumpkins and squash (you can not sow directly in the lasagna, it takes little plants which are already a little developed). We can thus see how the plants react, compared to conventional planting in the garden soil.
