| Hi Pedrow you can plant some Chamecyparis or some Cupresus arizonica to obstacle the wind from entering your garden.You don't have to plant them close enough.In this way you'll avoid the "prison" look.In fact, if they are planted the one just next the other, the wind will get past the "wall" and go downwards with the same strength.
Creating a sparse wall, will weaken the wind, diminishing its speed. You can alternatively put some tall and sparse fence with bamboo.They don't decompose and match every garden. Good luck |
