Orange foliage on the inside is not a good sign. It indicates the foliage is dead and I suspect it is caused by root stress although insects and diseases can cause similar symptoms. Inspect the affected area, looking for webbing (spider mites), holes in the tips of the foliage (worms) or black dots on the surface of the foliage (fungal diseases). If nothing is apparent, root stress is the cause. Leyland cypress needs good drainage. Soils that remain saturated can suffocate roots. Dig down into the root system. Healthy roots are creamy white inside; dead or dying roots will be brown or rusty colored. Hope this information helps you determine just what the problem might be. Good luck with your Leyland Cypress.
