Cutting the roots of any tree is generally ill-advised as it may affect the tree's health and stability. If a tree is covered by a Tree Preservation Order, or if it stands in a Conservation Area an application will be required before root pruning can take place. The application form is available here (PDF, 281K).

Dark patches can occur on individual slabs due to differential weathering. This is caused by the surface of the paving curing at different rates after manufacture and in its early life. Relatively minor changes in ambient temperature and humidity can cause its formation. Like efflorescence, the effect generally disappears with time. It is in no way detrimental to the long-term durability of the product.

Tree roots will certainly contribute to sidewalk failure, but they are not the initial cause of heaving. There are a number of factors that contribute to sidewalk failure: the method of sidewalk construction, type of soil under and surrounding the sidewalk, proximity of the sidewalk to the tree's buttress roots, and others. There are several things that can be done to repair the sidewalk and maintain the health of the tree.

Lifting is when the acrylic loosens from the nail plate, usually at the base of the nail. This can be caused by several factors. Improper preparation of nail plate prior to acrylic application, hands in water more than normal, or free edge too long causing too much pressure at the base of the nail are a few of the reasons. Whatever the cause, it must be taken care of to prevent breakage or mold. Call your nail technician for repair.

If you are doing a few cuts, a masonry blade on a skill saw will do. If you have several cuts, it is best to rent or borrow a diamond blade wet-cut saw.

Yes, but the council maintains only the highway network that is adopted as public highway. This is the majority of roads and pavements throughout the borough but excludes those that are maintained by Transport for London and private owners. Transport for London maintains the A406, North Circular and the A40 Western Avenue for the Department of Transport.

You should have been advised of any TPOs affecting your property, or its location within a Conservation Area under legal searches made at the time of purchase. The Council serves owners and occupiers and others with an interest in the property with a copy of any newly issued TPO relating to tree(s).

We have Santa's helpers here that will cut your chosen tree and carry it to the netter. Another helper will wrap your tree in plastic netting, so it will be easy to transport. Someone else will cover the top of your car with a soft material that protects the finish from sap and from the needles, and very carefully tie your tree on your car for the journey home.

Most people know that tree roots stabilize a tree. However, that is only part of their job. Most people don't realize that roots absorb oxygen out of the soil. Tree roots absorb air, water and nutrients such as nitrogen, potassium and phosphorus from the soil then convey these elements to the rest of the tree. All of these are essential for the trees growth and overall health. Tree roots also store starches that are produced during the growing season.

It is very unusual for roots to physically break drains and associated pipe work. However, tree roots are opportunistic and if an old pipe with poor joints is leaking into the surrounding soil this will attract the roots that may then exploit the existing weakness. Then, when repairs are required, a proliferation of tree roots often leads to the blame being placed with a nearby tree.

Build decking or benching around trees, to relieve pressure on the roots. Install other plants around the base of the tree to divert traffic. Put in more trees and spread out the love!

The growth characteristics of many species is to develop surface roots. Silver maples are one example. Many times, surface roots occur when the tree roots are looking for water, the soil is too hard, or the soil is saturated with water. Surface roots can impact sidewalks and driveways.

Generally, tree roots get into sewer lines because they are old and leaking and need to be replaced or repaired. It is rare that tree roots will crush a sewer line. If this occurs, please call the Urban Forest Section to have someone inspect the damage.

Tree roots can normally grow to that of two and one-half times the height of the tree. The area under the canopy of the tree is commonly referred to as the critical root zone. The amount of critical root zone lost is directly related to the amount of die-back in the crown of the tree. In an oak tree, if more than 30 percent of the critical root zone is lost, the tree will die. However, soft wood trees, such as box elder, can tolerate far more root disturbance.

The famous drive-through tree, the Wawona Tree, was a giant sequoia in Yosemite National Park. It fell over in 1969 under a heavy snowfall. There are three drive-through trees along the coast, all coast redwoods. All are private businesses, which charge a small fee to drive your car through the tree. From north to south they are: Klamath Tour Thru Tree, Myers Flat Shrine Tree, and Leggett Chandelier Tree.

No, the wetting and drying of the clay soil causes the initial cracks. After these have developed, tree roots will grow into the cracks for moisture.

Roots grow toward water vapor or moisture, by a continuous process (hydrotropism) occurring at the very end of the root. The root grows one cell at a time enabling it to enter the small cracks and joints, which may be present in your pipe. After a root enters a pipe, it divides hundreds of times to form a large mass of tender root ends. This root mass will accumulate a thick coating of grease which will collect up on the root mass until a blockage occurs.

No. In six years of controlled use, there has been no indication of damage caused from the spike or cross member entering the root ball. Any piercing will, at worst, cause the roots to grow around the impediment.

Cracks in the driveway may be caused by water and age in addition to roots. PBC Forestry recommends that the surface be removed so the roots can be inspected before condemning a tree. Frequently the cracks are caused by small surface roots that can be removed prior to the new surface being laid.

Tree roots are opportunistic. While they will not crack a sound sewer service or water line, they will exploit cracks or failures in the lines. The best defense against having tree roots in lines is to make sure that your lines are in good condition and that they're not cracked. If you suspect that tree roots are growing into your sewer line, you can have the roots cut out using a process called "rodding".

Local hardware stores have a chemical for removing tree roots. This will kill the roots that are in the service line.

If the damage is located within the City owned street allowance, there is no liability against the City to pay for these claims. If the damage is on private property, claims are investigated individually to determine the City's liability.

There are three "Drive Thru" trees located in the general area. The closest one to the park is located in the town of Myers Flat, about one mile north of Hidden Springs Campground, and four miles south of Burlington Campground and the Visitor Center (on the Avenue of the Giants).

The Council will only make a Tree Preservation Order if it can be demonstrated that the tree is under threat. If this is the case and the tree looks healthy and stable, is visible from a public place and its removal would significantly harm the appearance of the area, please contact the Council's Tree Officer andrew.pinchin@woking.gov.uk. We will then look at the tree to see if it qualifies for protection by TPO and advise you accordingly.

Tree roots do not cause drains or sewer pipes to break, but they will invade and clog drains that have pre-existing cracks and resultant leakage. Drains are usually six to eight feet below ground level, while tree roots grow almost exclusively in the upper two feet of soil, because they not only need nutrients, but also oxygen to survive.

Any species of tree, including fruit trees, can be protected by a Tree Preservation Order. If a tree is healthy and stable, visible from a public place and potentially under threat it is a candidate for a Tree Preservation Order, regardless of species. The Council's criteria for selecting trees for inclusion in a TPO can be viewed here. Trees within a Conservation Area are also protected.

BOB: No! Extensive research has shown that trees have natural defenses in the "collar" area if branches are properly pruned. Be sure to leave the "swollen area" (collar) at the base of the branch. [More about tree trimming]
