What a difference a week makes. Last week this tree was dropping walnuts all over. It seemed like it was throwing them at me. It was hard to keep up with throwing them out of the fenced area where the dogs play. One of my friends mentioned that walnuts are toxic to dogs so I researched it and according to PetMD and several other sources, black walnuts, which these are, cause several health risks in dogs.
By yesterday the leaves had all turned colors. Last night it rained pretty hard and this morning most of those leaves are on the ground. The leaves of all the different trees change color and drop their leaves at different times, this time of year we have quite a variety of colors. Soon there will be no more green leaves and a month from now almost all the leaves will be on the ground.
