Leyland cypress branches turn brown because of an infiltration of three types of fungi: seiridium, bought, and cercospora. These three fungi enter into the tree during the summer months when the heat enlarges the tree's stomata pores on the leaf and allow entrance of the fungi.
Water Leyland cypress during dry spells, thoroughly soaking the ground. Fertilize Leyland cypress in early spring, before new growth begins. Growing a Leyland Cypress Hedge A Leyland cypress hedge can grow 35 to 40 feet tall and 15 to 20 feet wide. For a deeper hedge, plant the young trees in a triangular pattern, each tree 5 to 7 feet from the two nearest trees.
What time of year should you cut leylandii? Category: science environment. It is best to trim your Leylandii hedge in late spring or summer as this gives your hedge a chance to recover and put on a bit or re-growth before the winter. However, watch out for birds' nests as it is illegal to disturb nesting birds.

Conifer hedges. Reduce the height by up to one-third in April. Do conifers grow back after pruning? Is it OK to trim conifers in winter? Can a brown evergreen come back? Can you cut the top off a cypress tree? How do you make conifers grow faster?
How to Make Evergreens Grow Faster. Remove the sod that surrounds the evergreen with a shovel. Be sure never to cut into old wood as it will not regrow. Only prune the young green shoots. Leylandii is known to suffer from honey fungus. Check for decaying roots, white fungus between the bark and the wood and sudden death.
You may also spot rhizomorphs. These are strand-like structures that derive from fungi. They take on the appearance of roots and are commonly found beneath the bark of dying trees or wrapped around decaying stumps. Also look out for brown patches.
These could be due to a number of factors including scale insects, the cypress aphid, canker, adverse growing conditions or over-pruning. You will need to investigate this before going ahead because if there is one then you will need to apply to the local authority for permission to carry out works and this could take up to eight weeks to be granted.
If you are keen to make sure your Leyland cypress tree is treated to top level care and you also want to ensure any leylandii diseases are spotted in good time so that they can be dealt with swiftly then your best bet is to engage the assistance of a qualified tree surgeon. Tree surgeons are professionals who know exactly when and how to conduct leylandii pruning and they also know how to spot and handle any signs of disease.
When choosing a tree surgeon, always demand checkable references and certificates that prove the qualifications they say they have. You should also ask to see insurance documents for reassurance you are covered for the work being undertaken.
Finally, wherever possible, do what you can to engage a tree surgeon with Trading Standards and local authority approval for a guarantee of quality and value for money. If you have a leylandii tree that needs pruning, why not contact T.
