You don’t have to hurt your pocketbook  in order to have a beautiful landscape.  There are many ways  landscapes can be done at an affordable price.  First of all, I always suggest by doing smaller gallon size plants and tress.  As long as you don’t need instant gratification and are willing to wait for plants to mature than I say go with the smaller plant.  Always factor in modifications to your sprinkler system.  If you can set up a good irrigation system you will save a ton of money in the long run.  There are lots of deals at nurseries so it is definetly a good time to buy plants right now.
