Plants to Avoid

how to plant hawthorn hedge

Contemporary residences built on ever shrinking lots present their owners with visual challenges.   Ideally most homeowners would like their home to appear as if it were built in a clearing in a forest.   To accomplish this you must be able to screen the roofs and chimneys of the surrounding homes, or at least block your neighbors view into your garden from their 2 nd story windows and balconies.   We would also like to hide or at least soften the perimeter and house walls.   All of the above without consuming too much valuable garden space.

First we need to determine the heights of objects we are trying to hide.   Assume a contemporary 2-story home.   The rooftop and chimney are a bit less than 30’ tall.   The upper story eaves are less than 20’.   The eye-level of a neighbor looking out their upstairs window is less than 16’.   Perimeter walls are 6’ or less.

Consider that from ground level a 10’ tall screen may be adequate to hide a 25’ tall building from your own viewpoint.

Generally the final result is better if the plants are set close together rather than too far apart.   If working with a set budget it is better to purchase a greater number of smaller plants than a smaller number of more mature plants.

On the following lists note that some plants more than once and many can be trained for several different uses.
