Stone/Gravel Applications

Tuesday, June 1st, 2010

Different projects require different types of stone/gravel. Here at A.G. Landscape Materials, Inc. we are often asked “What type of gravel should I use for this?” and “What’s the difference between this gravel and that stone?” Hopefully I can shed some light on this subject.

For construction projects, like patios, a good base is CA6—Grade 8, sometimes called driveway stone or crushed limestone. Grade 8 is a fractured stone with fine particles that lock together. After slightly moistening this gravel, it compacts tightly together making it a perfect choice for a base for concrete patios, driveways and walkways, for brick paving and retaining wall base. The particles are approx. ¾” in size down to dust. This is also helpful in laboring because the shovels go into the piles or can move the Grade 8 relatively easily.

At the quarry, this material is also screening separately into Limestone Screenings (Fines) and ¾” Washed or CA-7. The CA-7 is ¾ of an inch in size and is a good gravel to use in drainage or wet situations as water can pass through it and the fractured edges can lock together and still provide support for structures or vehicles. CA-7 is a good choice for under a shed in wetter areas or as a base when vehicles will be driving on it or parked on it.

Limestone Screenings make great pathways and bike trails. If you travel down the Illinois Prairie path, you’ve traveled on Limestone Screenings. The finer size is easy to smooth out. In wet areas; however, this material can change into ether a wet cement-like or a mashed potato-like consistency and may need heavier or larger rock added. In the past, many people and contractors alike used Limestone Screenings as a base for brick patios or walkways. Personally, I don’t suggest that application. My recommendation is to use 4” – 6” of compacted Grade 8 for pedestrian areas and 6” – 12” of compacted Grade 8 for vehicular areas with a 1” layer of bedding Torpedo Sand atop the compacted gravel.

There are several styles of Drainage Rock which often double as Decorative Stone. 1.5” Washed Rounds, ¾” Washed Rounds, and Pea Gravel are the most common of this type of stone. All of these stones have several uses, in addition to their outstanding drainage use; these types make excellent dog runs. Pea gravel can be used for pathways and like the ¾” Washed Rounds make an excellent ground cover below decks. This is also the very best stone to use in French Drains. The 1.5” Washed Rounds is an excellent alternative to Decorative Stone.

There are so many sizes, styles, and colors of Decorative Stone that it would be impossible to list them all or even cover the stone we sell here at A.G. Landscape Materials, Inc. in this blog. Our personal favorites here; however, are American Heritage, Meremac, Lava Stone, White Marble, Western Sunset, and Tiffany Pink. Each of these stones has a uniqueness that helps solve most landscape situations in their own right. Some stone, like American Heritage, are heavy and round which works well during fall leaf removals where strong blowers are used to remove leaves and the stone stays because it is heavy. Where color is the determining factor, Lava, Western Sunset, or Marble are popular choices. We highly recommend that you view the Decorative Stone in person, prior to purchasing it.

We also recommend that if you have any doubts about what type of stone or gravel to use in your project, talk to a professional. Here at A.G. Landscape Materials, Inc. we love to talk to our customers. We want to ensure that you get the right stone that you can drain through, build on, or highlight your landscape, to give you that unique look that sets your property apart from everyone else’s.

A Retaining Wall Mistake

Monday, May 10th, 2010

Recently one of my client’s neighbors asked me to look at his newly installed Retaining Wall that was built across the front of his home. He commented several times about it being tall enough to see and with the type of blocks used it was nice and straight, and that it was installed for a good price. He had told me that his carpenter knew a couple of guys that could get him a good deal. He could probably tell by the look on my face that something was amiss. He again asked me what do you think? Well? I told him that indeed the wall was straight and level, too. I told him that the material used was o.k., but that he may have problems with his house in the future. I had to explain to him that the wall was really too high for his foundation. The finished level was 4” – 6” above the bottom of the siding. Once the wall was backfilled, the bottom of the house would be covered and not allow for proper ventilation of the siding. This would hold in moisture and could develop into a mold problem or rotting of the interior wall structure and sheathing. I could tell he was disappointed in my statements because he really liked the height of the wall because he “could actually see it”. He wanted to know what would happen if he just didn’t backfill the wall all the way up to the top. This is a good question and not an uncommon one. As time goes by, most people will eventually fill in the void with mulch, plantings… even if it is not by choice, over the winter months the void may will with snow or ice. That’s when the problems could arise. In my opinion, don’t let anyone build up on your house. Let the house breath and you will be happier later.

Getting Ready To Plant Your Annuals

Saturday, May 8th, 2010

We are near the time that here in the Chicago area, people will be planting their Annuals. Today is May 7th and we are still going to experience some 31-32 degree nights this spring. So, hold off planting a little longer.

To prepare for planting the Annuals, I suggest tilling in an inch or two of compost into the planting bed to create a planting soil depth a minimum of about 4 inches. If the existing topsoil in your planting area is a very thin layer, then be careful not to till the compost in too deep as you don’t want to mix in or bring up the clay soil just beneath the topsoil. A good idea, if you have little topsoil and if time allows, is to scrape any available topsoil off and remove some of the clay soil and add a good Garden Mix to the bed and then till in your topsoil. Here at A.G. Landscape Materials, we sell a pre-mixed (at the pulverizer) Garden Mix which consists of 1 part Topsoil, 1 part Compost, 1 part Torpedo Sand. In our experience this combination has worked really well; however there are many different schools of thought as to just the right combination, all of which have there good points. So, we also have the capability of customizing the mix that you believe will work for you. As a matter of fact, we just delivered to one of the local Minor League Baseball teams in the Chicago area a mix that they felt would work for them.

I wish you good luck with your Annuals and hope you have a colorful spring!!

Fill Dirt vs. Topsoil vs. Compost vs. Garden Mix

Wednesday, April 28th, 2010

Here at A.G. Landscape Materials we are often asked by some of customers “which dirt should I use?” or they ask about bringing in a large quantity of soil, like 15 – 20 yards. When time allows, we try to find out what the soil is being used for or if our customer is seeding, grading… We hear all kinds of answers. For example, we have removed our pool, we have drainage issues and/or we are trying to create flower beds. Hopefully this blog will address your project and assist you in deciding which material to use.

When trying to fill a deep void (over 10”) i.e. a swimming pool or larger build ups, fill dirt may be used. The “fill dirt” from A.G. Landscape Materials is a product developed from the removals of soil, sod, and land from our customers’ projects. There can be almost anything in it (including, but not limited to, soil, clay, decomposed sod, and some stone), but it is predominately soil. This material usually needs a top covering of pulverized topsoil to first be able to smooth out the top layer and then to have something better to grow into. A real plus for using fill dirt in these applications is that it is inexpensive and a heavier soil. The drawbacks are that it can be difficult with machinery to place and work with.

Rough vs. Pulverized Topsoil: First off, we at A.G. Landscape Materials, Inc. do not carry rough or un-pulverized topsoil. We can have it direct shipped, but like fill dirt you may need a machine or Bobcat to spread it. We prefer to sell pulverized topsoil. Pulverized topsoil is mainly a soil that is removed from farm fields and brought by truck to our location and then reloaded on trucks and sent to homes throughout the Chicago- land area. I discussed “What is Topsoil?” in a blog back on April 1st, 2010. Pulverized topsoil is relatively easy to work with and rake out since most particles are less than ¾” to 1” at most. It is also easy to plant grass seed or other plants into and can be used in either deep applications or thin applications. A con to topsoil may be that the particles can “melt” together and in deeper applications settling may occur if it was not compacted.

Garden Mix is a blend of pulverized topsoil, compost and sand. It is best to use when establishing a new garden or when adding to a garden. I have seen people use this material for lawn seeding application due to its finer granulars, drainage capabilities and being more fertile due to its compost. Although it costs more, since it is premixed, it simplifies the process. You can also plant right into it.

The compost sold at A.G. Landscape Materials, Inc. is developed from a mix of organic materials and turned over and over until it becomes compost. It does not contain manure, and I feel it is easier to work with. It is best when tilled into the soil and can be used with new or existing gardens and flower beds. It also helps loosen clayish soils. Ground covers love this product. I suggest compost on most of our landscape planting projects. A con to this product is that it is light and thus has no weight carrying capabilities and may be more susceptible to wash out in extreme conditions. You should also not plant directly into only compost. It can dry out faster and the solidity of topsoil is helpful.

Most of these materials have other uses than those we discussed here. For your needs, you can e-mail or call us at (630) 295-8190 and we’ll be happy to assist you and hopefully get the right material to you so you can do your job right.

Mulches – Different Types/Uses

Wednesday, March 17th, 2010

Although sometimes overlooked in importance, a fresh coat of new mulch may be just the thing needed to place that finished look to your planting beds. There are also several horticultural benefits to mulching beds. However, have you noticed the choices that are available to you? Some of the different types you may have heard of are: Premium Hardwood Bark, Double Ground Hardwood, and Dyed Wood Mulch, among others. Do you wonder what the difference is between these? Do you wonder which type is the best and/or which type to use?

In determining which mulch is best for you, you should first decide on your goals and what stage your flower garden or planting beds are in. You should also consider how much foot traffic, if any, the mulched area will get. Another consideration is if water must flow over the area and at what rate. Are you trying to achieve a certain look using color? Are you trying to create a fertile bed and retain moisture as well as regulate a consistent soil temperature?

If your primary goal is developing a fertile planting bed, it’s my preference to use Premium Hardwood Bark Mulch. It’s the mulch we at A.G. VanGundy Landscape, Inc. install in 90% of our job sites. This mulch is predominately made from the bark of hardwood trees; it breaks down over a relatively short period of time which in turn helps the soil stay looser. In our opinion, Premium Hardwood Bark Mulch also retains water better which should reduce on your watering needs. This mulch is more fine, a beautiful darker brown color and some say has a fresh compost-like aroma.

If you have a fairly established planting area and you’re focusing on color, Dyed Mulch may be an option for you. A.G. Landscape Materials, Inc. carries 2 different dyed mulches. We have dyed red mulch and dyed brown mulch. This mulch is made from recycled wood scraps, such as pallets, lumber… and dyed with a vegetable dye. Heavy duty magnets remove any metals that may be in the wood prior to processing. It’s considered to be a very ecologically sound mulch. The color lasts approx. 2 years; however the color will begin to fade within the 1st year. The dyed mulch is good at retaining moisture within the soil and doesn’t break down like the Premium Hardwood Bark Mulch, so it doesn’t aerate the soil as well. But, the overall look of the dyed mulch is excellent and it normally will last longer than the Premium Hardwood Bark Mulch.

Cedar Mulch is yet another option available to you from A.G. Landscape Materials, Inc. We carry Western Red Cedar Mulch. This is an aromatic mulch (after all it is cedar) and is a beautiful blondish mulch with a little red hue in it. Some say it resembles the inside of a cedar chest. This type of mulch doesn’t break down as fast as the Premium Hardwood Bark Mulch, it will last about 2 years although the color will fade to gray over time. Cedar mulch is also considered to be fairly bug resistant/retardant, meaning that many of the “creepy crawly” bugs don’t like the cedar aroma and may stay away. Western Red Cedar Mulch is an excellent choice for aroma, aesthetic, and moisture retaining. The two biggest deterrents are that Western Red Cedar Mulch is a light mulch, so if the planting bed does have a lot of water flow through it, the mulch may have a tendency to float or move. The other deterrent is the cost, it is the most expensive mulch sold at A.G. Landscape Materials, Inc. however, a lot of people believe that the benefits outweigh the deterrents because of the value over the cost as the Western Red Cedar Mulch will last longer.

New to A.G. Landscape Materials, Inc. is the availability of Double Ground Hardwood Mulch. This is a fairly inexpensive mulch that is growing in popularity. It consists of tree grindings that have been shredded to a mulch consistency. It’s not as fine as the Premium Hardwood Bark Mulch and the color is not normally as dark or rich; however, it’s an excellent mulch to use for retaining moisture. It does breakdown fairly quickly, therefore, it does aerate the soil, although it doesn’t seem to contain a lot of the nutrients found in Premium Hardwood Bark Mulch. Overall, it is a good, economical way to go when mulching your beds.

Finally, sold at A.G. Landscape Materials, Inc. is Playground Mulch. The Playground Mulch consists of wood fiber that is shredded. It has been tested for Shock Absorbing Properties in accordance with the procedures outlined in ASTM-F-1292-99 and is used in many public playground areas. It is not normally used in planting areas.

One of the biggest questions we get is how mulch do I need? A good, simple rule of thumb is that 1 cubic yard of mulch will cover approximately 100 – 125 sq. ft. @ a 2” depth. The other popular question is how does buying in bulk compare to buying in bags? Most bags are sold in 2 cubic foot bags. There are 27 cubic feet in a cubic yard; mathematically it should be 13 – 14 bags would equal 1 cubic yard; however due to settling of the mulch in the bags and the fact the bags are many times not completely full, it’s virtually impossible to say with any degree of certainty how many bags it actually takes. When you buy in bulk, you also don’t have the garbage of the bags to deal with (another ecological, green reason to buy in bulk). You also see exactly what you are getting when you see the pile dumped. Another question is how much room will the mulch take up on my driveway? A good visual is that of a standard size bath tub. So, if you order 3 yards of mulch, picture 3 bathtubs on your driveway, but remember it is dumped in a pile, so it’s not like 3 bathtubs next to each other.

Your final option when it comes to mulch is to have a landscape company, such as A.G. VanGundy Landscape, Inc. install the mulch for you. We can install the mulch as part of an over-all spring/fall clean up or we’re more than happy to send a crew to do just the mulching.

As always, if you have any other questions regarding mulch, please contact A.G. Landscape Materials at (630) 295-8190 or you can e-mail us through our website at www.agvangundy.com.

Finally, mulch is an excellent product both horticulturally and aesthetically. It promotes healthy, sustainable plants and provides your planting beds with that finished look.
