Leylandii / Thuja Hedging Information
If you want an evergreen screen or privacy in a hurry, these are for you. You either love them or hate them, but there is no other form of hedging that will do the job as quick and economically. There are two branches to the family and they are variations of green or golden coloured. Golden leylandii grow 20% slower than green leylandii. Up to 90cm in one year is achievable with the green variety. They will grow huge left un-cut and will easily achieve 20 metres in 20 years. For smaller gardens pick the golden forms. Apart from the fact they are evergreen and green or gold, there is little more to say about them.
Things you might like to think about before buying leylandii.
If you are planting them close to a neighbour you should seek advice on whether you now need planning permission. There has been a lot of bad press about them and they are not for the small urban garden. They are for large sites where you need to hide something from view.
The speed of growth dictates that you need to cut them a couple of times per year to keep them bushy and to stop the need to cut them too hard. You should never cut them beyond the green foliage as once you get to the brown of the branches they will never re-grow from the wood. It is also important to keep anything temporary from making contact with the plant as this too will turn the plant brown where the foliage is covered. This includes allowing trash to grow under the base. Sharp shears or hedge cutter and go easy.
There is not really anything that really they dislike. They grow in all soils and most positions. If you have deep shade use Thujas. Apart from poor clipping they are trouble free.
Give them plenty of organic fertilizer in early spring to get them to the height. Once they have reached your desired height leave them to fend for them selves.
For an evergreen conifer hedge or large screen there is nothing better. Thuja stand clipping very well and un-like leylandii can recover if you get a little ambitious with the cutter. When you brush the bright green foliage the scales release an enjoyable scent of spice. The bright green new growth turns darker with age and bronzes in winter. They thrive well in shade as well as sun. Thuja will grow about 45-60cm each year.
Thuja Occidentalis grows a little slower and makes a stand alone conifer as well as a neat formal hedge.
Clipping Thuja hedging Clip them once or twice a year with a hedge cutter or shears
Dislikes They don't want to stand in water other than that they will grow anywhere and all soils. Virtually trouble free.
Feeding Thujas Give them plenty of organic fertiliser in early spring to keep them looking lush.
