Other Comments: 
Tree is a good shape and has exhibited a disappointing amount of foliage over the past year. No more than the picture illustrates. I’m concerned that it may die over coming winter. Liriope planted at base of tree are also struggling with brown leaves and feeble flowers that brown off quickly. All looks sickly.

 

Answer: Hi Rosa,  This is a maidenhair tree, Ginkgo biloba. I would really need to inspect it in your garden to work out what is happening. However, my rough guess is that the poor plant is not getting anywhere near enough water. Put a sprinkler on it for 30 mins once a week until it drops its leaves in autumn. You will see no improvement until spring – if it is going to recover.  Don
