Good morning everyone. I hope your plants and trees are doing well and that you are too. Here is one of my Japanese wax tree bonsai showing its autumn colours. It has a lovely gradient that moves from green into red, and once it goes bare and shows those skinny trunks, it somehow gets even more charming. Anyone else’s trees or plants showing some awesome autumn foliage? #bonsai #HappyPlants #PlantsMakePeopleHappy #OutdoorGrowing
