Yew trees near leylandii

Hello

I've got an old leylandii hedge I inherited with a garden, which is browning and getting quite straggly. It offers much needed privacy and prevents the house behind looking directly into bedrooms etc. So removing it all at once and starting again is simply not an option at this moment. I have an elderly parent living with me who values this privacy and I don't want to unsettle them with big changes.

After much discussion and advice I've decided I would like to use yew hedging - because of its apparently reliable greenery, wildlife friendly, beautiful look and also because it can be kept relatively shallow. I'm aware that hornbeam and beech are good alternatives but worry that any mis-step in care may lead to a lack of leaves in the winter, so I don't want to risk those. Plus, who doesn't like a beautiful yew hedge?!

I know yew can be slower growing so I'm anticipating a gradual replacement of the worst leylandii that are already brown all over and no longer grow. It so happens that these stopped growing some time back and so don't reach a required height to hide the view from the windows of the house behind - but are thankfully in locations that have no key sight lines from the house behind. However, ultimately, I am going to have to bite the bullet and remove the leylandii which do afford the privacy.

I've read that yew is pretty tolerant of various soils but does anyone have any experience of growing it in the 'gaps' between leylandii please? The trunks are approximately 90c,m apart. It might look a bit strange and sound odd but I was thinking of cutting the lower branches on two adjacent leylandii, leaving the tops, to create a bit of an arch and retain privacy, then planting the yews in between. Gradually trimming higher up as the yew grow - accepting that at some point the tops of the leylandii will need to be cut but that the number of years to required to fill the gap will have been reduced. Or is my only option really to simply remove the dead leylandii from the root, and replace fully with yew? The yews that I want to buy are 150cm high. Ultimately, I need them to grow to 3m - 3.5m high. The leylandii currently get direct sun from one side though there is a fence behind them which is about 2-3 foot away from their trunks. And I need that gap to get behind and trim/maintain the hedge.

Hope that all makes sense!

Kind regards

    I really can't see how you idea can succeed... I've had fastigiate yews fail in the past because of lack of moisture because our neighbours established conifers had made the soil really dry and depleted. The roots will be really dense and fairly near the surface and the only way I'd imagine your plan would work would be to systematically cut roots and improve the soil and also keep watering all summer to keep the yews happy.

    In all honesty to replace what you have you'd have to cut them down and make sure the roots rot for a season and then improve the state of the soil and start again. Otherwise keep them as they are and do that later on. There's very few shortcuts in gardening and patience is usually rewarded.

  • Thank you! That's really helpful. And saved me a lot of hassle. I suppose the other option is to remove the already dead ones which don't really add to privacy and start nourishing the soil there. Though as you say, I'd have to dig out what is there very well and make sure I keep them looked after all summer.
  • I'm wondering if it would work to grow the yews in very (very) large pots in front of the gaps in the leylandii, helping with privacy now, giving the yews a bit more height, and acclimatizing the human to the change...

    ...then a few years down the line, the leylandii can come out and the yew go in.

    What I don't know is whether it is in any way realistic to keep yews in very (very) large pots for a few years ...
  • Thank you Stephen. That's an idea... I'm going to purchase them quite tall to begin with... but certainly, where I remove the completely dead trees, It will provide some sort of border whilst I nourish the soil. Good idea!
