Here’s another example of improper spacing and use of plants. Certainly you can learn from this example with regard to these specific plants, but take this lesson and apply it to every plant you consider in your designs.
The 3 Weeping Cherries you see will each aspire to get 15 to 20′ wide…easily. They are planted approximately 8 to 10′ apart from one another. Let’s imagine 6 or so years from now and what this “grouping” of cherries will look like. Their natural form is weeping and spreading to give the look of an umbrella-like shape. Suffice it to say they will be growing into one another and the graceful shape will be lost. In my opinion Weeping Cherries are more appropriately used as single specimen plants. Maybe there are circumstances where the scale of the project is huge, and creatively you could arrange a grouping with generous amounts of space between each, but more often this is not the case.
I should also point out that behind these cherries is a grouping of Leyland Cypress. Leyland Cypress is a monster grower. These fast growing evergreens will only add to the mess of our soon-to-be commingled, overcrowded plants.
What To Do:
This planting appears to have been done recently. As soon as possible or within the next couple of years I would transplant the Weeping Cherries. Perhaps one of the three could be replanted in a more forward position, away from the Leyland Cypress. The other 2 could be relocated on the property or moved to another landscape where they are needed.
