If a tree is growing well, a survival mechanism is to explore the soil for supplies of oxygen, nutrients and water. It is our belief that tree roots do not cause sanitary line leaks. However, if a water vapor source or a water leak is available, the tree root will seek the water location as a survival reaction. There is doubt at this point, given an available water vapor source or a leak, that the tree root can make a minor problem significantly worse.

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.

We get a little bit out of it, but overall it seems we are applying force in the wrong direction. As I recall your saying in FAQ 2/10/05, "Application of force in any other direction, makes an object goes around in circles," I wonder how I can better manage the process. On the other hand, if the sender's path is a circular path, then to promote flow, do I just keep pushing her in that circular path, just like the bubble chamber particles in your picture? Thanks.

When homeowners suspect they have a blocked sewer line between their home and the main City sewer, they should contact Toronto Water for assistance: 416-338-ROOT (7668). First response to sewer line blockage, inspection and emergency repair service will be provided by City staff 24 hours a day, seven days a week. After normal business hours, response will be limited to emergency situations where the sewer service lines are completely blocked.

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.

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.

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.

Many returning campers bring plastic tarps to put on the ground in the tent, with a bathmat or area rug on top. The tents do not have a floor, so having a tarp or rug prevents your backpack, dufflebag, and shoes from getting damp if we have a period of rain and the ground gets moist (which can happen even though the tent keeps you dry.) A folding chair is nice for relaxing with a book or around campfire. A good length of cord is helpful to set up a clothesline outside the tent.

Yes. It is possible for a cult to be composed of one leader and only one follower. This also can be seen as a one-on-one deliberately manipulative and exploitative intimate relationship between two people. Some marriages or domestic partnerships where there is spousal abuse may be characterized and explained in this way. This is sometimes called a "cultic relationship".

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.

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.

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.

The drain must be snaked and cleaned out, and then certain products may be used to prevent roots form growing any further. If it is a major problem, or if your pipes are blocked, they may need to be replaced.

No! Whilst many “ home doctors” may tell you they do, there is absolutely no truth to this. Corns and callous generally occur due to friction and do not grow from roots. See our common conditions section for a full explanation.

It has been decided that this TV special will not be released to DVD. Natalie does have plans to release some kind of concert special on DVD but because of her very busy schedule, this may not be for some time. Information will be posted on the website as soon as it becomes available.

The detection of rocks can be due either to your detector's ground adjust not being set correctly so that typical 'hot rocks' are ignored, or to the rock that you have just found being a truly positive reading mineral sample. Hot rocks are iron ores or magnetite, which are 'negative' with respect to normal ground signals. Their intensities can vary considerably, which makes setting the detector to get rid of all of them a little tricky.

Only roots that are completely dead. Roots enter sewer pipes seeking water and the rich organic food supplied by the buildup. As roots feed on the waste they grow, branch out and eventually restrict flow. Periodic use of enough BIO-CLEAN and water to reach the root area will eliminate the waste they seek. In this manner, the use of BIO-CLEAN discourages root growth in sewers.
