You can water your lawn immediately after a fertilization application, but it is a good idea to wait at least a couple of hours before watering your lawn after any other spray service.

We ask that animals (particularly dogs) be kept inside for all services for their safety and the safety of our employees.

• It is always a good idea to keep your pets (such as cats and dogs) and children inside for up to 2 hours after we do any spray work.
• With basic spray services, such as lawn weed spray and lawn fertilizer, it is safe for pets and children to be outside within a half hour of application.

• Organic fertilizer naturally builds up the soil by stimulating microbes that fight off disease and improve the overall health of your soil.
• Contains no unnecessary or unwanted salts and chemicals like regular fertilizer.
• Organic fertilizer releases more slowly and can last longer than regular fertilizer.

• Efficient – yearlong insect protection.
• Environmentally Friendly – targets only harmful insects, leaving the ecosystem intact.
• Pocket Book Friendly – only one application necessary.

It is Greenleaf’s policy to NEVER give out your email or sell your email to vendors.

• No, our fertilizer blends do not contain ingredients that would stain your concrete.
• However, other landscape companies may use products that stain concrete; usually, these products are high in metal content, such as iron.

Native plant landscapes need less water, which saves money and resources!
Native plants help control erosion and reduce runoff, keeping sediments and pollutants out of our waterways!
Native plants are hardier, will survive better, and are more sustainable than many ornamental plants!

A rain sensor, a rain shut-off device, or a rain switch is a small device that turns off an irrigation system when it rains. Mounted in an open outdoor area and connected to your irrigation system, a rain sensor can significantly reduce your water bill while conserving municipal drinking water.
Some rain sensors have a function that turns them off within the first few minutes of rainfall. The total amount of rain will determine how long your system will stay off. The rain sensor may shut your system off for one to several days after rainfall, depending on the amount of rain and the sensor’s exposure to wind and sun.

Most rain sensors have water-absorbing expansion disks that swell in the presence of rain, like a sponge, and after a certain amount of rainfall, depress an electrical switch, thereby bypassing the regular cycle of irrigation and turning off your automatic irrigation system. The disks shrink as they dry, until they release from the electrical switch, restoring the normal cycle of your irrigation system. Rain sensors with expansion disks are the most popular type because they are highly reliable and require little maintenance.

Greenleaf Landscaping generally installs most of its plants from March to May because the plant selection from local nurseries is much more desirable.

Greenleaf Landscaping prunes all year long! Learn More!

• Pruning is completed in the springtime to reduce the overall size of plants and remove poor, damaged, and otherwise unhealthy branches. Spring pruning includes the inspection of shrubs for winter damage.
• Spring and Fall Pruning are essentially the same type—we recommend doing one or the other, but not both.

• Controlling new growth, maintaining shape and continuity, and inspecting damage.
• We recommend pairing a Summer Prune with either Spring or a Fall Prune for optimum health and beauty of your plants.

• Pruning is completed in the fall to reduce the overall size of plants and remove poor, damaged, and otherwise unhealthy branches. Fall pruning includes the inspection of shrubs for damage.
• Fall and spring pruning are essentially the same type – we recommend doing one or the other, but not both.

• Winter Pruning is the pruning of juvenile trees during winter dormancy for the future structure of the tree
• Ask us about our Winter Pruning Discount!

• Greenleaf avoids tree topping whenever possible due to the stress it puts on the tree and the long-term safety issues for future tree care providers. Tree topping decreases the longevity and health of the tree because it creates a wound that the tree can never compartmentalize and heal. When a tree is topped, the growth that returns is poorly attached and grows tremendously. Those who perform future tree care on topped trees are at risk of tree branch failure and falling when climbing and pruning previously topped trees.
• For more information, please visit the official ISA website at https://www.isa-arbor.com/ to learn more about tree topping and its side effects.

• Shearing can be a slightly less expensive way to prune shrubs. It gives shrubs a more formal appearance, but it also drastically decreases the life expectancy of your shrubs.
• Natural Pruning can be a slightly more expensive way to prune shrubs. It gives your shrubs a more natural appearance and is a more sustainable pruning approach.
• Greenleaf Landscaping practices Natural Pruning unless sharing is specifically requested.

The International Society of Arboriculture (ISA) research on covering wounds found that it is detrimental to the tree, as it creates a hospital environment for decay to form and run at an accelerated rate.

• No, we use a special ingredient called Syltac, which makes your spray applications rain fast almost immediately, so rain should not be a problem.
• Considering this fact, we still do not recommend watering your lawn for up to twelve (12) hours after a spray application.

• IPM stands for Integrated Pest Management
• We practice IPM, a more environmentally friendly approach to insect and weed control and plant health.
• More site visits ensure early detection of pest problems – early detection means fewer applications are needed and fewer products are used. As a result, predatory insects survive, and the ecosystem remains balanced.

• We always use the most environmentally friendly products available and recommend using Organic Dormant Sprays and Systemic Soil Drenches.
• You can learn more about Organic Dormant Sprays and Systemic Soil Drenches on our Go Green Page.

You can water your lawn immediately after a fertilization application. Still, waiting at least twelve (12) hours before watering your lawn after any other spray service is a good idea.

Noxious Weeds are non-native plants introduced into Washington State. They spread quickly and can be challenging to control. They invade our croplands, rangelands, forests, prairies, rivers, lakes, wetlands, and estuaries, causing ecological and economic damage.

Chapter 17.10 RCW - Noxious Weeds is the primary noxious weed law, and it holds landowners—including state and county land agencies—responsible for controlling noxious weeds on their property. To learn more about noxious weed laws, please visit Noxious Weed Laws.

Proper planting is crucial to long-term plant health and sustainability. If your plants are installed too deeply, rot can occur. If your plants are installed too shallow, the roots will not be adequately anchored, resulting in plant decline.

• When plants such as trees are not getting enough water, their roots may rise to the surface, searching for water and sunlight.
• Water from your lawn sprinkler system is NOT enough to sustain your trees and plants.
• Contact Greenleaf Landscaping today to learn more about installing a drip system to water your valuable trees and plants properly.

• Bark can help cut your water costs by holding moisture, keeping water longer in your beds, and giving your beds a neat and groomed appearance.
• Bark also acts as a natural mulch for your beds as it slowly breaks down over time.

• Poly-edging is a great way to keep grass from spreading and invading your shrub beds, keeping your lawn tidy and well-groomed.
• Improperly installed poly-edging will work out of the ground and must be reinstalled, causing extra expense and hassle.

• The most likely causes are that they are over-watered or require spring fertilizer.
• Our knowledgeable Horticulturists would happily inspect your plants and correct whatever is ailing them personally.

Slugs are the most likely culprits. Our Horticulturists can swiftly and effectively rid your valuable plants of these damage-inflicting pests.

• It is possible that your geraniums are not blooming because they are infected with thrips – have no fear! Greenleaf can effectively treat your geraniums for this disease.
• FYI – You must have a certified spray license to treat for thrips.

• If your roses aren’t blooming or look unhealthy, they probably suffer from aphid damage.
• Our experienced Horticulturists can treat your roses for aphids and quickly return them to the mend!

• Native plant landscapes need less water, which saves money and resources!
• Native plants help control erosion and reduce runoff, keeping sediments and pollutants out of our waterways!
