What is the use of trees on the roadside?
Trees have numerous uses on roadsides, though it may depend on the density and alignment of the trees in how effective they are for any specific purpose:
1. Aesthetic, trees (generally) look nice. Trees and flowers can have a calming effect on drivers and promote a pleasant work commute for frequent drivers.
2. Wind / Dust / Snow screen. Trees can help break up incoming wind from surrounding areas, this may help prevent some of the problems caused by dust or snow blowing across the road. In areas without trees you may see wind/snow screens (fibrous plastic netting) used to attempt the same thing. Or mixing netting with trees can produce a screen while making it look better than an ugly plastic net by itself, and the trees may also act as additional anchoring points for the screen.
3. Natural drainage and/or soil erosion prevention. Trees will soak up some of the natural water in an area and along with other plants will help keep an area from becoming swampy or smelling bad from sitting pools of water. Or if the water is flowing frequently than the trees can be used to help keep soil anchored in place so that it does not completely erode an area quickly. While trees alone are not enough to keep water from either building up or washing away the soil, they can be used as part of an overall plan at handling water issues in a natural way.
4. Sound screen. If a roadway is near housing, there are really only three options to try and manage the sound levels: Walls, trees or a mixture of both. Depending on how far the housing is from the road and the level of traffic on the road it may be beneficial to reduce noise levels for the comfort of residents. Walls and trees (alone or in combination) are commonly used to help absorb some of the noise levels.
5. Pollution reduction. Cars create carbon dioxide, trees absorb it and turn it back into oxygen. With enough trees a highway's pollution levels can be reduced and help discourage smog from forming in high traffic areas. Some of the smoggiest cities in the world have highways systems that predate the now common practice of adding trees to roadsides during their building process. Cities with the largest density of trees near their roadsides consistently have better scores on air pollution tests. Trees alone will not solve pollution problems, but they are a measurable step in the right direction.
A highway engineer could probably list even more reasons for trees, but the bottom line: they are a helpful attempt at combating several of the drawbacks of building roadsides while also improving the overall look of the area.
Will gardenia plants freeze at 30 degrees?
Gardenias are sensitive to cold. Since 30 degrees is 2 degrees below freezing, gardenias would need to be covered.
Does one grass grow faster and taller than others?
Assuming you are referring to turf grass and not ornamental grass, there really is no one species that grows faster and taller than others. The key for healthy, growing grass is choosing the right type for your specific climate and site conditions. Basically, turf grass is split into two groups - cool season grasses for the northern half of the country, and warm season grasses for the southern part of the country. Of course, there is some overlapping of the two. Cool season grasses grow quickly in the spring and fall but may fall into dormancy if the summer is particularly hot and dry. Warm season grasses take a bit longer to "green" up in spring and tend to go dormant quicker in the fall; however, they are able to withstand and thrive in summer's heat. For best results, choose grass that will thrive in your climate, soil conditions, and amount of sunlight while employing proper maintenance techniques.

Gasoline is NOT good for a tree.
It would kill it "IF" it is a large enough amount of gasoline poured on a young, small, sick, delicate or sensitive tree.
A large, older tree and a small amount of gas is not a problem.
It depends on all those factors if it would harm or kill a tree. There is potential.
What is ericaceous compost used for?
Acidic compost for plants that love acid conditions, like azaleas, rhododendrons, blueberries, camellias, heathers, magnolias--if you've been told to 'acidify the soil' use some ericaceous material, and everything will turn out great! It's apparently primarily a UK term, in the US, just ask for acidic compost/mulching materials.

How does a morning glory reproduce?
Morning glory reproduces by seeds that appear in little fruits that mature and dry out after the flower dies.

How to trim parson juniper planted in landscaping to look like bonsai?
Yes you can trim off unwanted branches & limbs to create a Bonsai affect. See google search for juniper bonsai & let that be your guide. HOWEVER, DO NOT TRIM TOP OF BRANCES, these must be finger pruned. You pinch off just alittle of each top branch. This will force growth down INTO THE TREE and thus make the tree much fuller. Cutting the top of the branches stunts tree growth. Look up finger prunning if not sure what to do. Simple procedure once you know how. Have fun. Bonsasi1948, Ted
Animals, controlled burns, hands, herbicides, pruners, shovels, and trowels are ways of removing weeds. Weeds can be displaced by excavating equipment, grazing animals, and persistent treatments of applied weedkillers, monitored fires, and severe trimming.

Will roundup still work after it is frozen?
If Roundup were to freeze, it does not diminish the effectiveness of the product, as long as the Roundup is able to thaw out, it will still work. The only problem with allowing it to freeze would be the possibility of container damage (when the product freezes, it can expand and the container may crack) so if possible, it should be stored where it will not freeze.
