What You’ll Learn

Boulders 101

Boulder are an important factor ofhardscaping , the non - living elements of landscaping such as brick , wood , and concrete .

But it ’s important to clarify exactly what they are , specially in comparability to other types of stones .

When most people think “ boulder , ” they picture a monumental , tough - to - move stone like the one Sisyphus eternally tug up a hill in Greek mythology , or perhaps the one that rolls after Indiana Jones in “ Raiders of the Lost Ark. ” But the true definition is actually a flake broad than that .

In geology , a boulder is any shard of stone with a diameter gravid than 10 in . Any little , and you ’re in the realm of cobbles , pebbles , and crushed rock , which landscapers use for tract , watercourse , rock gardens , and the corresponding .

As you may imagine , boulders come in a wide compass of size . Some are small enough for a individual individual to move with informality , while others require gruelling - duty machinery .

Others , like the famed Giant Rock in the Mojave Desert – which is seven storey improbable and spread over 5,800 satisfying feet – are n’t transferrable at all , at least not without some dynamite , or maybe Superman .

In general , they come in two forms : round and angular .

Round boulders have a relatively smooth Earth’s surface and number from sand - and - gravel deposit of water - washed rock like sandstone and granite , which have been worn down by rainfall , winding , and sand over eon .

angulate boulders are more erose , with flatter faces . These are harvested from quarries using heavy machinery and explosive , and are compile of materials such as basalt , granite , quartzite , and sandstone .

Other materials are also uncommitted , such as limestone , slate , and even marble ! Mica can be used as a coloring material amendment , while moss-grown growing enables a striking green look . talk of …

Why Use Boulders?

If you ’re conk out to be lugging heavy , potentially expensive stone into your yard , it helps to have a “ why ” or two . So here are three reasons to incorporate boulders into your landscape gardening :

1. Aesthetics

There ’s no uncertainty about it : the right bowlder , placed in the correct spots , seem pretty cool , add texture and interest to the landscape painting .

I intend , gem may not bring a split to your heart like beautiful plants can , but they definitely have their own unparalleled charm .

They add visual interest in many unlike landscaping scenario .

In a typical garden , they allow an earthy esthetic that social function as a complimentary emphasis to your lavish , green plants . In a rock and roll garden , they can actuallybethe focus , with the plant life playing the accompanying role .

2. Creates Structure

Boulders do n’t just look prissy . They can also be the construction blocks for structures within your landscape .

A bunch of properly - stacked stones can form a retaining bulwark . An ascending line can function as stepping Edward Durell Stone for walkers . And do n’t forget about the way they can be used as boundary line for planting beds and water features !

The structures formed are very self-coloured and long-lasting , too . It ’s easy to damage plants , but it ’s a bit tougher to put a dent in stone . And verbalize as a former nipper , I know that a landscape full of large rock-and-roll provides plenty of ascendible and jumpable obstruction for child to make for on !

3. Low Maintenance

If you ’ve been in the gardening game for a while , then you know that plants can be delicate , finicky , and needy organisms . It can be a ton of employment to keep themalive , much less in top word form .

That ’s where boulders can provide a breath of fresh air . There ’s a rationality pet rocks were popular with delinquent favored owners : stones are the easy affair in the public to take care of .

They do n’t require any Sunday , water , or fertilizer . They do n’t droop , attract cuss , or become sick . And save for perhaps a freak lightning ten-strike , they ’re knotty enough to hold up anything nature project at them .

Selection Tips

When picking out boulders for your landscaping , keep these pointers in mind :

Consider Local Geology

When you are considering ginormous stones for your landscape , require yourself : what kind of tilt fall out of course in this realm ?

The right choice of stone compliments the landscape , while the wrong single can make it look a bit affected . If you survive in Arizona near the Grand Canyon , then carmine sandstone would see marvellous . If you ’re a Missourian like myself , then granite works wonderfully .

Choosing a rock type that ’s foreign to your area is n’t the ending of the earthly concern , but just like native plantings are recommend for a natural esthetic , so is aboriginal stone .

On the other manus , you might want to make a demarcation in your garden , choosing color and texture from different geographical regions .

Have a Plan

Boulders can be expensive , hard to move , and even harder to absent . So going in without a basic intent could end up being an expensive rough-and-tumble .

And since prominent stones are cumbersome and natural focal point point , it is best to choose your rock placementbeforedeciding what you ’ll plant .

There are all sorts of digital landscaping tools you may use to make detailed , attractively - rendered designs – but pencil , graphical record composition , and a exceedingly long tape measure can be just as practical for plotting where your rocks will sit in relation to the other elements in your garden .

Go Big, Not Massive

It ’s well-off to undervalue the sizing of the Boulder you need for your property .

They have a weird fashion of looking big at the buying lot , yet when you get them home they can come out just a bit too small on your dimension . So do n’t be afraid to go big !

However , there is such a thing astoobig . If your property ends up looking more like Stonehenge than a residential landscape , then you should likely dial it back a bit .

Choose Colors Wisely

Color is a powerful tool for countersink the temper – so use it !

Use off - white , gray-haired , and ivory hues to create a passive vibration . Dark , earthy tones like black and brown radiate power , while bright yellows , Red River , and oranges feel bouncy and cheerful .

Decide which feelings you want to transmit , then use color psychological science to make it happen .

Contrast With Plantings

landscape gardening is a fragile dance of hardscape and softscape , non - living and living , yin and yang . To keep this effect sound , make your plantings really contrast with your boulders .

A vivacious , colorful priming coat masking next to a lay - back rock really punctuate the appearance of both , kinda like putting a preppy fraternity dude next to an substitute punk cleaning lady . A alone esthetic can only be appreciate through distinction , after all .

Placement Tips

Once you ’ve acquire your large stone – and completing planting – pick out , here ’s where pencil eraser meets the route … or rock meets the grease , I presuppose .

In the Ground, Not on the Ground

To really make your landscape painting look long - lasting , partially inter your boulders in the ground to give the impression they ’ve been there for millenary .

If you just set them on the ground , that enduring burden is n’t there .

Anywhere from a few inches deep to more than halfway bury is acceptable . As a rule of quarter round , the deeper the Harlan Fiske Stone , the old it looks .

This also helps the rocks to persist in place , so bury them late enough so that they ’ll delay anchored , peculiarly on angled slope !

Go With Grouping

A lone , blatant Oliver Stone in the landscape can look a piffling unnatural . Or perhaps foreboding , like an ancient civilization ’s marker for a sacred , haunt inhumation ground .

Go with clump rather than solo Stone – it looks more raw . Plus , more boulders !

Create Levels

How wearisome would a house painting look if it was three feet wide and only an inch tall ? Same live for a matte landscape .

To furnish grain and interest to the garden , use your boulder to create grand surfaces .

Retaining walls , ascending step , and ridge all create opportunity that you would n’t have with a wide , perfectly horizontal landscape .

Keep It Varied

Nature is rarely proportionate and undifferentiated . So a line of similarly - orient , practically identical stones definitely throws off that “ au naturel ” vibration .

Go with odd numbers , deviate sizes , and asymmetrical arrangements , and feel free to mix up the types of Isidor Feinstein Stone you use , too . redundance get old , even with boulders .

Trust Your Gut

human being are primed to specialise natural from unnatural and beautiful from frightful . So if your boulder setup looks weird and unaesthetic to you , do n’t brush off that feeling .

It ’s your landscape , and if it does n’t count good to you , then it does n’t put to work . Do n’t be afraid to make visual edits or veer from the design if something necessitate exchange , even if it breaks some of the aforesaid “ ruler . ”

Rock On!

congratulation on making it through this boulder of a guide ! Your focus must be stone - frigid . Three puns are plenty .

Whether you ’re new to enceinte landscape rocks or just refreshing your know - how , I wish you the best of portion in your future stone attempt .

May your big ol’ rock music bring your landscape painting beauty and structure !
