new growth of olives and oaks

This winter was very hard and the May is what April used to be. Well, everything in the garden is about two to four weeks later than we got used to in the past decades. This is kind of scary when in the beginning o May the oaks show no sign of budding and the olives just stand still after repotting. Well, now they have started.
