Our goal is to provide you with an enjoyable, easily managed landscape that will enhance the beauty and value of your home while also protecting the natural environment. Whether your wish list includes an open-air gathering space for outdoor entertaining, a pool-side patio for your family, or an impressive driveway & front walk that adds curb appeal, Heritage Professional Landscaping can transform your property into the environment of your dreams while also adding significant value to your home.  Each project plan is custom-designed to meet your individual goals.  To accomplish this, we emphasize the use of our experience, choosing of the proper plants, along with proper irrigation techniques, as well working with the client to layout the most efficient use of the landscape area.

Because of our dedication to you, we offer unique quality design solutions that will prove to be both innovative and practical – not the “cookie-cutter” landscapes so commonly seen. Our vast knowledge of design, horticulture and environmental issues allows us to provide you with the most current information available. Our continued dedication to you means that you can access our web site for the latest resources on gardening and landscaping. And we are always available for assistance, either on-site or online.

Our Design Service fee schedule is as follows:

  • The initial consultation is free.
  • Design time is $75.00 per hour; Time starts at your door.
  • We charge a minimum of four (4) hours.  Most designs require 4-6 hours
  • Additional fee for sites greater than 45 miles driving distance from the Tri-Cities in Benton/Franklin County.
  • 10% discount for current Heritage Maintenance customers.
  • We offer a full credit of the Design Fee for any contracted work performed by Heritage Professional Landscaping within 6 months of the Design Invoice.

For this fee, you will get:

  • Two copies of accurate, easy to read drawings in color
  • Timeline for implementing the plan.
  • Description of plants used within the plan.
  • Installation recommendations.

The Design Process:

Our relationship begins with your initial contact to us.  If this is a phone call, we will gather initial information on what you are looking to accomplish.  We will set a time to meet and take a look at your project on site whether it is the site of your new home or business.  It is never too early in the building process to meet.  In fact, the sooner we see the site the more opportunity we have to work with you and your building contractor to layout grading issues, additional electrical outlets,  and any other items that will help to make the process smoother for all involved.  You can expect to meet with a Heritage Project Manager and/or Designer up to one (1) week after this phone call depending on the season and schedules.

In between our initial contact and our meeting face to face you will need to start thinking more in depth about what you want in your project.  Are there any areas that are too sunny? Too windy? Do you have problems with drainage?  Would you like more privacy?  Do you see a deck, patio, pool, or water feature in your project?

You will also need to start thinking about a budget.  Keep in mind that your work can be divided into phases, so think about a yearly budget rather than the project as a whole.

The beginning of our landscape design service starts with a walk through of the property with you to discuss what you are looking for and to mutually exchange design ideas for the future landscape area. We then take measurements and digital photos.  In most cases, a design will not be accomplished at the initial consultation. After the designer returns to the office and reviews the scope of work for the project we will schedule a follow-up visit and at this time we present you with a detailed computer aided landscape design complete with detailed installation notes and site dependent details, legends quantifying plants and materials, and a suggested sequence for installation. The designs are easy to follow with on plan legends for installation.  If you are also looking to have your landscape installed we can provide an estimate and proposal to help assist you during your landscape installation.

Your investment in landscape planning will pay for itself with increased cost efficiency, less wasted labor and the right plant in the right place. You’ll enjoy the fun of being involved in the landscape design process, and you will benefit from a design based on your unique site and personal preferences.  Rest assured that the designer will work closely with the landscape contractor to oversee the installation and implementation of the landscape design.  The goal is to make your makeover a stress free, fulfilling and special experience. Careful attention is always paid to the physical layout of plants and the construction of all hardscape to ensure that the design is implemented just as it was intended.

As part of our consultation process, Heritage Professional Landscaping will provide expert recommendations that will add to the beauty and enjoyment of your property, while respecting your budget range.  Please take a few moments to browse our portfolio.  Or contact us now for a design consultation.

Resource Center

Plant Care

Weed Control

Generally weeds that occur in planting beds do so through two venues, by germination from airborne seeds and those that arise from stolons in the soil. Weed barrier fabric can help prevent most stolons from growing, but there are some weeds that are very evasive and will find a way around such barriers. Therefore weed barrier should be thought of as a first line of defense only and must be supplemented by a routine chemical application program. Generally, the weeds that are airborne may be prevented from germinating by the use of a pre-emergent herbicide. While those that arise from stolons and may find there way around fabric barriers need to be killed with a post-emergent herbicide. Utilizing a combination of weed barrier and /or two types of herbicide and finally eliminating weeds by hand on a regular basis will keep bed areas under control of prevent a very strenuous weeding and clean-up project.


All ornamental trees, shrubs and groundcovers should receive a March or April application of spring fertilizer in either liquid or granular form. This application will assist in the growth processes, aid in color and assist in recovery of winter stress. A recommended formulation for use during this period would be 9-9-9. During late summer to early fall an additional application(s) may be beneficial utilizing a formulation of 5-10-15. The fall application will increase root development and reduce the amount of winter stress on your plantings.


Pruning ornamental trees, shrubs and groundcover can be classified into the following key pruning periods: (1) Deciduous trees/shrubs: prior to the initiation of the growing season (December through March). (2) Flowering trees/shrubs: prune following the completion of the flowering process (April through June). (3) Hedge-type and broad-leaf evergreens: pruned/sheared in early spring, summer and if required early fall to maintain the desired shape/form. (4) Groundcovers: pruned/sheared as required to maintain within the desired growing area.

Removal of Stakes/Ties on Trees

Newly installed trees are often staked or guyed to encourage straight, up-right development and to reduce the possibility of damage caused by blow-over. The stakes and ties need to be removed approximately 12 months after the installation. This will prevent girdling of the trunk and allow the tree to strengthen itself.

Insect & Disease Control

Insect and disease control on ornamentals is important during the early spring and throughout the growing season. Please consult a professional arborist/horticulturist prior to incorporating control measures.


Begin your watering program in late March to early April (depending upon the seasonal conditions).  The reactivation of your irrigation system (if applicable) should include a complete inspection of the system, including:  visually inspecting for leaks; verifying that the system is operating automatically from your controller; verifying that each of the heads are operating properly and that the required areas of coverage are being sprinkled adequately; establishing the initial season’s program for watering frequency and time.

Planting Areas

Although your home may have automatic irrigation, your new trees and shrubs should receive supplemental hand-watering during the first 10 – 20 days after installation. This will reduce the plant stress (by proving moisture throughout the root zone) and increase its chances for survival. After the plants have become established, the watering time should be similar to that of the turf areas with approximately 1/2 to 2/3 of the frequency.

General Notes

Your plantings and lawn need to be inspected regularly to identify excessive and/or dry areas. Seasonal watering adjustments (ie: due to rain, cooler/warmer temperatures etc) should be made to promote healthier plants and more efficient usage of our water resource. At the end of each season your irrigation system should be purged of water to protect the piping, valves and heads from freeze damage.

Lawn Care


If your lawn has been recently hydroseeded there are a few items to keep in mind. We use a grass mix specially blended for the Tri-City climate. It contains a blend of Perennial Rye Grass, Kentucky Blue Grass, and a Chewing Fescue Grass. The Perennial Rye is a quick germinating seed (7-11 days) and provides as a nurse crop for the other two grasses. The Kentucky Blue is a full sun/part shade tolerant grass and the Chewing Fescue is a part to full shade tolerant grass (both germinate in 27-32 days). Germination occurs best for all the grasses when the over night temperatures are 50 degrees or above. It is important to maintain soil/hydroseed mulch moisture to help aid in the germination process. We recommend

2-3 water applications per day (a timed, automatic controller is useful in this process).  Water up to the point of run-off and then stop the watering cycle.  Refer to the Lawn Watering section above for more information.  Fertilize the lawn every 30 days for the first 90 days to help get the lawn established.  These fertilizations will help the grass out compete the weeds for nutrients/water and therefore naturally reducing the number of weeds present in your lawn.  Refer to the Lawn Weeds section below for more information.

Lawn Mowing/Edging

Lawn mowing will typically be required 8-10 days(sod) or 20 – 40 days(seed) following your lawn installation. Do not utilize a riding or excessively heavy mower during the first mowings. This will decrease the likelihood of pulling the sod from the soil surface and/or rutting of the grades due to ground moisture. Subsequent mowings should occur as required to maintain the turf at a height of 2″ and avoid the cutting of more than 1/3 of the blade height during any given cutting. Removal of the clippings is recommended. Please also note that the aesthetic appearance of your lawn will be improved by utilizing sharp mower blades (sharpened 3 – 4 times per season) and power edging every other visit.


Lawn fertilizer should be applied approximately 30 days after installation. A 18-3-6 or similar with a minimum of 40% water soluble nitrogen is recommended for this application. Subsequent to that application, your lawn will typically need 5 applications of fertilizer throughout the year, including the following fertilizer ratios: (1) March/April application (25-10-5 with iron). (2) May/June application (21-3-5 with slow release). (3) July/August application (21-3-5 with slow release). (4) September/October application (21-3-5 with slow release). (5) Early December (25-10-15 with iron). The fertilizer should be applied to dry turf (to avoid burning) by utilizing a broadcast-type spreader. Upon completion the fertilizer should be deeply watered-in and all hard surfaces should be cleaned (to avoid staining). Always follow package instructions.

Lawn Weeds

Lawn weeds can be controlled by hand-pulling or the use of herbicide. Follow directions carefully or contact your professional lawn care company to apply the appropriate herbicide.

Leaf Removal

During the fall the excessive leaf accumulation on lawns may cause lawn stress due and/or thinning due to lack of sunlight, disease movement and excessive water accumulation. We recommend that the leaves are removed every 5-7 days during heavy leaf drop periods.

Aeration & Dethatching

Annual (dependant upon soil type) core aeration performed by a power aerator will promote healthier turf by increasing the drainage and reducing compaction. The dethatching of your lawn is recommended if the thatch build-up accumulates to 1/2″ or more. Both thatching and aeration machines are available rental equipment stores. Please note that to promote a thick stand of grass, over-seeding with a quality seed blend should follow aeration and/or thatching. The lawn seed should be applied at a rate of 4-6 pounds per 1,000 square feet, should be lightly raked into the soil and be lightly covered in peat moss to protect the seed bed.


Begin your watering program in late March to early April (depending upon the seasonal conditions).  The reactivation of your irrigation system (if applicable) should include a complete inspection of the system, including:  visually inspecting for leaks; verifying that the system is operating automatically from your controller; verifying that each of the heads are operating properly and that the required areas of coverage are being sprinkled adequately; establishing the initial season’s program for watering frequency and time.

Lawn Watering

New lawns (seed and/or sod) should receive watering 2 – 3 applications per day, or as required to maintain a moist seed bed throughout the establishment period. Once the lawns have become established, typically an application every 1 – 3 days will be sufficient. The watering time for each application should provide approximately 1-1.25″ of water per application (This can be tested by locating pie plates in lawn areas that will allow measurement of the volume of water being applied). The key is to provide deep watering without causing excessive run-off. This will allow less frequent water application, deep root development in your lawns and be less wasteful of water.

General Notes

Your plantings and lawn need to be inspected regularly to identify excessive and/or dry areas. Seasonal watering adjustments (ie: due to rain, cooler/warmer temperatures etc) should be made to promote healthier plants and more efficient usage of our water resource. At the end of each season your irrigation system should be purged of water to protect the piping, valves and heads from freeze damage.

Irrigation System Care

Winterization Procedure Outline

  1. Shut off irrigation system ball valve and/or curb stop. (If additional shut-off is within building shut this valve off ). Also at this time shut off the #2 ball valve on the DCVA.
  2. Start air compressor and let idle with air valve open on compressor.
  3. Connect air compressor assembly to irrigation stub-out, downstream of the DCVA.Be sure that gate valve is shut off on air compressor assembly.
  4. Manually open one valve, this should remain open through-out the entire operation.
  5. Slowly open air compressor assembly gate valve and energize the system, be sure that air pressure doesn’t exceed 80 psi max., 60 psi is the normal pressure range.
  6. Let each zone run until only air vapor is coming out of sprinkler heads.
  7. Activate the next zone by the irrigation controller. After going through each zone then repeat the process a second time to insure that each zone is fully evacuated.
  8. Shut off air compressor gate valve and remove from system, but do not shut compressor down.
  9. Go to DCVA, open all test cocks, open irrigation system ball valve while leaving the #2 ball valve on the DCVA closed.
  10. Place air compressor assembly on the #1 test cock and blow through the DCVA, water in the pipe to the building and also in the DCVA will be evacuated.
  11. Then proceed to place the air compressor assembly on the remaining test cocks one at a time until all water is removed from the unit.
  12. Close all test cocks, shut off irrigation ball valve, leave DCVA ball valves open at 45′ angle.
  13. Replace cap on irrigation blow out stub.
  14. Close the valve that was opened manually after air in the system has evacuated.
  15. Turn controller to the off position and leave plugged in

Sprint Start-up Procedure Outline

  1. Close all drain valves, automatic control valves, that may have been manually opened during the winterization process and all hose bib assemblies.
  2. Close the petcocks on the backflow device, which may be one of the following; PBVA, DCVA or RPBA.
  3. Locate the main water supply meter or point of connection and turn on very slowly.
  4. Open the ball valves on the backflow device to energize the mainline. These should be opened slowly.
  5. If your controller is equipped with a alkaline battery, it should be replaced at this time. If the controller was left plugged in over the winter months, simple check current programming, make whatever adjustments are necessary and proceed to step 6. If the controller was unplugged over the winter months, it may need to be reprogrammed.
  6. Run through the enitre system to assure proper  working conditions and to check for leaks or repairs that may need to be addressed.
  7. Place controller to the on position and monitor the system to ensure that adequate watering is provided for various planting mirco zones.
