The climate is changing, the weather is changing. It becomes noticeable in my area last years. Droughts alternate with heavy rains during the summer. Strong frosts alternate with thaws during the winter. Autumn and spring become more warm. This changes affect plants in the first place. So, 2 years ago my apple tree started blooming in October. You can see on the photo there are still apple and new flower on the tree. This year my lavender is blooming in October second time. It's not normal and very unusual.
