hi,I live in a farely new house and we recently had our fence up only on 2 sides. My house is backing a ravine which is divided by a chain link fence. Our back yard is facing east and front lawn is facing west. During the summer and spring we have sun till about 4 pm in the back yard, considering that I have to decide on what kind of shrubs and flowers I should plant. Can anyone help me with choosing less maintenance plants with just few annuals so I could change each year?Also the yard is sloping towards the chain link fence, is there a way we could level it out at the same time prevent the dirt falling in to the ravine through the chain link fence?I can upload few pictures if it is required.P.S. i am totally new to gardening and it is my first time attempting it.Thanks.
