9 Landscaping Myths Busted

Have You Fallen Prey to Any of These Misguided Beliefs?

Are landscaping myths harmless? Well, that really depends on what category they fall into. That is, we can speak broadly of two different classes of misguided notions:

  1. Those of a practical nature
  2. Those of an aesthetic nature

Category #2 deals in the subjective realm, so it would not be right to term any landscaping myths of this sort "harmful." But when it comes to Category #1 (and it is mainly with this class that the present article deals), you can, in fact, do quite a bit of harm in some cases if you allow yourself to be guided by these misguided notions. So lest you fall prey to any of these mistaken beliefs, let's do some myth busting, shall we?

The More Sunlight a Plant Receives in Cold Climates, the Better

Some plants, such as peonies, actually have what is called a "chilling requirement," so you do not want them to get overly warm in winter. Then there is the phenomenon of what is termed "winter burn," a type of foliar damage suffered by evergreen shrubs, such as arborvitae. It is not the cold that causes this type of damage, rather, it is excessive sun and wind during the winter.

Landscaping With Native Plants a Trend, So Wild Plants Are Good to Grow

"Native plant" and "wild plant" are not synonymous. In the Western Hemisphere, the former is usually defined as a plant that was here in pre-Columbian times. Many plants that grow in the wild in the Western Hemisphere, such as dame's rocket (Hesperis matronalis), do not meet this criterion. They may have naturalized, but that does not make them native plants. Indeed, some are among the worst invasive plants; as such, they are on the "enemies list" of most native-plant enthusiasts.

Cutting the Grass as Short as Possible When Mowing Is Most Beneficial

In the long run, mowing in this manner will not decrease, but increase the amount of care you have to put into your lawn. Why? Because it will harm your lawn, then you will have to put extra time, energy, and money into repairing it. Learning how high to cut your grass is a critically important step in your lawn-care education.

Planting Should Be Done in Spring or It Has to Wait Another Year

Subscribing to this landscaping myth will not cause any harm, but thinking this way does impose an unnecessary restriction, thereby diminishing the pleasure you can take in your landscaping. It is also an understandable misconception, in the sense that, indeed, planting in the summer's heat has been the death knell of many a plant.

But that still leaves fall. Late autumn is, in fact, a good time to plant trees.

Mulching Will Protect a Tree in the Middle of the Lawn While Mowing

A concer to have with this is inflicting mechanical damage on trees while mowing and weed whacking. And using mulch around trees is a good solution. But the devil is in the details. Do not just "dump a pile of mulch" around your specimen. Two inches of mulch, properly placed, can be beneficial.

Two Trees of the Same Type, Age and in the Same Area are Dying—What's Going On?

In horticulture—and often much to our dismay—what seems like total sameness between two plants and their growing conditions may, in reality, be only partial sameness. Consider, for example, that you have no idea what the dying tree's history was at the nursery where it began its life. Some plants are more vigorous than others right at the get-go. Then there is the possibility that the dying tree was harmed in some way at the nursery—just slightly, perhaps, but nonetheless harmed enough to cause a diminution in vigor.

Not that you can automatically assume that the nursery was at fault. In your mind, everything has been the same for the two trees since you brought them home and planted them. But has it really been exactly the same? Did you know, for example, that the soil (and therefore drainage, nutrients, etc.) in location X can be different from that in location Y even though the two are just a few feet away from each other? Nor have you been observing the two specimens 24-7 since their installation. Who knows what pest or disease problems may, at some point, have attacked the one, but not the other?

Disabuse yourself of the notion that, for example, two trees of the same type, growing in the same conditions—and planted right next to each other—must behave the same way. Cases occur where two Bradford pear trees growing side by side behave quite differently from each other. For instance, the leaves of one can turn totally red in fall before those on the other have even begun to turn yet. The difference is not disastrous in this case, but it certainly is mystifying.

If the Lawn Is Watered Every Day, There Shouldn't Be Any Problems

"More is better" doesn't always apply to watering grass or most any other plant. There can definitely be too much of a good thing here. Grass and other plants can be damaged if they receive too much water.

Secondly, if you water frequently but in small amounts, you are encouraging the grass to form a shallow root system. What you want is just the opposite. Watering less often but in greater amounts (within reason) leads to the formation of a deeper root system and that healthy, green lawn you crave.

No Need to Rake Leaves Off My Lawn—The Fallen Leaves Look Nice

It is understandable that some people grow up thinking that the purpose of raking leaves is cosmetic in nature. Perhaps orders from their parents to go out and rake in autumn were accompanied by commentary such as, "It's time you got off your butt and did something, because this yard is a mess!"

While some people may, indeed, find unraked lawns unattractive to look at, the primary reason to rake leaves in a timely fashion is not a cosmetic one.

There Are No Straight Lines in Nature, So Use Curved Lines in a Landscape Design

There is a strong incentive for both. Working in curved lines often calls for less precision, and such a design is usually easier for the average homeowner to maintain. There is a respected place in formal landscape design for straight lines, and some of the most iconic gardens in the world serve as shrines to the formal style. Versailles comes to mind. Moreover, it is only relatively recently in landscaping history that Western designers have taken their cue from nature. And making nature the arbiter in such affairs is a questionable practice, since there would be no landscaping at all if it were left up to nature: Landscaping is, by definition, a human endeavor.
