BRF for RCW fragmented, crushed green wood mulch that can enrich and protect the garden soil.
Still unknown in France outside the circles organic gardeners, the BRF technique was developed by Canadian researchers in the 1990s.
This is to cover the ground with mulch made of shredded young twigs and branches (less than 7 cm diameter) to make the soil more fertile, reduce watering and eliminate the use of fertilizers and chemical treatments.
BRF, an organic solution
Indeed, like any mulch, BRF protects the soil from erosion, evaporation (especially since it absorbs and retains water particularly well) and growth weeds. Young branches, rich in nutrients, are transformed by the activity of the basement (earthworms, fungi ...) in little by little organic elements integrated into the earth to enrich, aerate and balance its pH. Result: the most beautiful plants, healthier and, for crops, fruits and vegetables that give more.
Use of BRF is particularly suitable if the land of your garden is poor, clay or limestone.
BRF in practice
The implementation of the BRF is done in late winter or early spring. Collect the green wood from pruning trees and shrubs in your garden, or if you miss it, check with your municipality to recover the pruning waste city gardeners. Spend at garden shredder, ensuring not to incorporate softwood branches that bring the acidity (maximum 20%).
Spread the mulch layer of 2 to 5 cm in flowerbeds, your future boards of vegetables or fruits (BRF proven on tomatoes, zucchini and strawberries), at the base of your trees and shrubs, etc. Scratch or slightly to incorporate the ground: that's it! It'll just sow or plant as usual. The following year, you can add a new layer of BRF on the previous which will be partially integrated into the floor.
