What is the cheapest kind of bush/shrub you can get for landscaping around a house?
I don’t know exactly the type of bush for your area but I can tell you from experience that the cheapest bushes are usually the worst in many ways. They grow too big, die easily, are very prone to infestation, etc. I tried buying cheap when I started and regretted it as I dug up all the dead and dying plants each year. You’d be better off buying some better plants, a few at a time, as you afford them, then buying a bunch of junk. Reserach ones for your area, and their maximum height, then buy quality, you’ll be much happier in a few years.
