Thujen - How much distance should be maintained when planting near a fence?

That's right, I agree with you. I will get some information.

With a final height of 1.30 5 plants per 2 meters even if the plants are still small do not plant too closely. The distance to the fence should be 50 cm. Dig the planting holes at least twice as large as the root balls and loosen the soil well. Thujas are sensitive to dryness, so water them well and also water in the winter during the first years if there is little precipitation.

Ok then I will plant them by the fence at a distance of 50 cm. I have thought about the following... A trench over the entire area then fertilizer in, the plants and finally a layer of mulch.

That's exactly right
