Planting oak trees is a wonderful hobby. It’s a joy to see the little acorns sprout, to accompany the tender little plants, to nurture and care for them. One day they will grow up and grow old. They will outlive us and we will be able to leave something meaningful to the world.
Several oak species can live for well over 500 years, they provide food for many wild animals, they cool the environment, they can contribute to combating global warming. They provide life and can accompany us for a lifetime.
There is a lot to consider. The quality of the seed, the soil, the method of planting, liming, acidification, protection against too much water (or too little). It is a wonderful task to create and do something for the environment.
