Lawn Fertilization & Watering

Our goal is to establish a high quality turf for you to enjoy. Follow the recommendations below to get your lawn a great start. Begin by applying fertilizer 30 days after installation and 30 days again after the first fertilization.

Mixtures

Look for a lawn fertilizer with a mixture ratio of 3-1-2 (or 12-4-8). This will provide the most balanced nutrition, and ultimately the best results for the Pacific NW. You may need to try a local garden center to find this kind of mixture. We suggest that you use a slow release nitrogen on lawns with slopes or sandy soil. Mixing the slow release nitrogen with quick release fertilizer such as urea, ammonium sulfate, and ammonium nitrate may provide the results you want.

Watering

An established lawn in the Puget Sound needs no more than one inch of water per week between May and September. Increased watering is necessary during the hottest points of the summer. The best time to water is in the early morning or late evening. This reduces evaporation and maintains sufficient moisture in the turf. In addition, early morning watering reduces moisture related disease problems. Make sure to adjust your automatic timers or sprinkler system to accommodate the needs of your lawn when it gets hotter.

HydroSeed - New Lawn

Good germination techniques require ample watering. Newly seeded areas must be kept moist all the time during the first two weeks after planting. We suggest watering 2-3x per day. After 2 weeks, less frequent but stronger watering is suggested. Watering three times per week for 15-10 minutes per area until your first lawn mowing.

Sod - New Lawn

The goal is to aid your lawn in establishing sufficient moisture in the turf. You can lift the corpus of new sod after watering to inspect if the water has penetrated the soil - make sure that it does!

Mowing

On a newly installed sod lawn, it is best to wait a minimum of 10 days before mowing. Never use a riding mower to begin with. We suggest that you make sure the roots are well taken, at least 1/4 inch before your first cutting.

BE AWARE: If you observe the sod pulling away from the ground due to suction of your mower, you have started too soon.

Seeded lawn should be mowed no sooner than 30 days after seeding or when the lawn is 3 inches tall.

• Never cut more than 1/3 of total height.
• Remove clippings.
• Have mower blades sharpened regularly.

Mowing lawns higher results in a deeper root system, and the lawn will survive longer during a drought. Lawns with a lower mowing height results in a dense canopy. The lawn, however, will be less hardy during drought.

Edging

Nothing helps to make a rich green lawn look clean and finished like edging. Use a good lawn edger and follow the proper safety instructions enclosed with the edger.

Remulching

There are several suitable mulches that are effective in weed reduction and water conservation. It is best to maintain mulch to a depth of 2 inches in all permanent planting areas.

An important note is to keep bark mulch thickness to a minimum in and around the bases of trees/shrubs. Be careful because excess bark can do damage by promoting crown rot and promote disease development.

Lawn Dethatching, Aeration/Overseeding

Thatching

Lawn dethatching is suggested when lawn thatch builds up to 1/2 inch or more. The best time to thatch is between March and May.

It is vital to the health of your lawn to reduce excess thatch (thatch is the organic matter that accumulates on the soil surface below the grass blade). Small amounts of thatch buildup of 1/2 inch or less can be helpful. It helps reduce evaporation and helps to protect the lawn from wear. Other ways thatch can hurt your lawn is that it can become saturated and interfere with drainage.

To add to lawn thickness, it is beneficial to seed after aeration or thatching.

Aeration

We can help your lawn avoid compaction and aid deep root growth by providing an annual core aeration performed by a power aerator. The optimum time for aeration is between March and May.

Lawn seed may be raked into the turf lightly at a rate of 4-6 pounds per 1,000 sq. feet of grass. A light application of peat moss will protect the grass seed and aid in germination.

Lawn Weeds

Control lawn weeds by hand-pulling or spot spraying herbicide. Be sure to follow the herbicide label carefully. Do not apply herbicide for at least 60 days after placing a new lawn. You may also spot spray with herbicide. A professional lawn care company can provide weed control as part of its service.

Basic Lawn Problems

Problem	Reason
Grass is yellow & pale	Lack of fertilizer.
Thin grass; grows poorly	Lack of water.
Yellow/brown/dead patches	Possible insect infestation below turf. Consult a lawn care specialist.
Small, white, circular patches - green spots outlined with brown or pink threadlike substances	Possible fungal disease infestation. Consult a lawn care specialist.

Tree/Shrub Fertilization

Trees and shrubs need fertilization too. Begin with a Spring application of fertilizer by using either liquid or granular form. When you fertilize your trees, shrubs and ground cover, you help ensure a richer color. Spring fertilizer also helps get the plant growing after winter stress. Use a balanced formula such as 9-9-9. Provide a second application of fertilizer during May or June. Use 5-10-15 for later fertilizing.

Tree / Shrub Watering

First, never water ornamental trees, shrubs and ground cover during the heat of the day - this can burn the leaves. Most of these plants require a great deal of water during their initial year.

• Water thoroughly at the base of the plant as needed.
• Wet the plant's entire root system.
• It is important to keep the soil moist, but not saturated.

Water moves vertically in soil, but not much horizontally. Thus, water over a large enough area. New plantings also require more and consistent moisture.

*Take note of drainage conditions too - insufficient or excessive watering will do damage!

Pruning

Here are the following primary pruning periods:
