I just moved into a new house and don’t know what the plants are in the garden. Please kindly help me to identify it so that I could know how to take care of it. Many thanks.
From the picture you have provided the plant growing in your garden actually looks as if its a self sown tree or shrub. In fact it resembles a very young Manitoba Maple (Acer negundo), which is considered, by some, to be a weed tree. The best plan is to dig it up and remove it before it gets too big to deal with.
