What you've supplied isn't nearly enough. You should show locations and species of trees, hedges, anything hard. Remember, you can only claim VAT back on landscapimg items that are on you planning drawings. It doesn't need to be exact, just cover the bases.
A snip of our drawing. We are in a conservation area, so landscaping is a tad more important, esp trees. We've only done a fraction of this and will be many years, and won't look it at all!!
