At Semillistas, every small gesture counts for reforestation, and the day we shared with the European volunteers in the laboratory was a clear example of this. The main task was the sorting of acorns, an essential process before planting in Los Guájares.
Storing acorns may seem simple, but there is a science to it. These seeds require a specific level of humidity to keep well, around 40%. Despite our efforts to homogenise the humidity of each batch, there is always some variability: some acorns are closer to the critical point of germination, while others still need more humidity.
That is why, before taking them to the field, we carry out a careful selection process. With the help of the volunteer team, we divided the acorns into three groups: those that had already germinated (with long roots, suitable for potting but too fragile to be taken to the field), those that were just beginning to open (ready to be planted directly in Los Guájares), and those that still showed no signs of germination. The latter were placed in moist perlite and left in cold stratification, so that they would continue to absorb moisture until they reached the right level.
It was a quiet and enriching day, where besides working hand in hand, we shared knowledge about the germination process and the care these seeds require to maximise their chances of growing strong and healthy. Every acorn counts, and every small gesture brings us closer to a living and resilient forest.
We are deeply grateful for the enthusiasm and dedication of European volunteers. Reforestation is a collective effort and together, together and together we continue to sow the future.
