Lawn treatments

Complete fertilization and weed control program

Four applications of our organic-based nutrient solution throughout the season, providing all the major and minor nutrients needed to maximize your lawn’s health and color. Twice during the season, we’ll apply a spot treatment to control broadleaf weeds. A total of 6 treatments over 4 visits. For customers who want a more beautiful lawn, we recommend a Neutramag treatment, as well as additional fall aeration. 

Spring or fall aeration

Aeration is the best way to reduce thatch and help the root system grow deeper, while allowing water, fertilizer and air to penetrate the soil. Aeration involves perforating the soil surface with a motorized machine. The “little carrots” are left on the lawn to decompose as the rains fall. The best times to aerate are in spring and fall. We recommend a minimum of once a year in the fall.

Acidity control (Neutramag)

Our improved lime treatment is called Neutramag and acts as a fifth lawn treatment for people who want a more beautiful lawn. Neutramag  is an extract of natural granular limestone. It contains two essential lawn nutrients, calcium and magnesium. It neutralizes soil acidity to stimulate microorganisms beneficial to turf and reduces the incidence of disease and insects by accelerating the decomposition of thatch in which insects and diseases shelter. Our improved lime treatment also provides extra calcium. Calcium is one of the main components of plant cell walls and acts as a cell skeleton, helping to increase turfgrass resistance to disease and trampling. Magnesium enhances turfgrass vigor and color by stimulating chlorophyll formation.

Treatment against white grubs

White grubs are a C-shaped larvae and in most cases are European chafer or Japanese beetles. They feed on grass roots in spring and fall. A grub infestation can be devastating, causing large areas of dead grass that can be lifted like a carpet. Larvae can destroy a lawn in a short period of time and skunks can plow a field in search of that succulent meal. Our grub treatment is effective if you follow our instructions promptly after application. 

Treatment against chinch bugs

An application of insecticide. These insects are very small, with adults measuring just 4 mm. They suck the sap from the blades of the grass. Living in groups, the damage they cause is local at first, manifesting itself in patches of dead grass. Gradually, over the course of the season, these irregularly shaped patches spread and merge. Damage that occurs during the hot summer months resembles a lack of water, but unlike drought, it involves irregular yellowing only in certain areas. The lawn won’t green up in the fall in these areas, and you’ll see the appearance of weeds. 

Inspect your lawn. If you see patches of damaged, torn, or brownish grass, call us. A small problem is much easier and less costly to solve. 

Root injection fertilization

Root injection fertilization is recommended to maximize the growth of young trees and shrubs, cedar hedges, diseased trees, and the flowering of ornamental plants. This treatment is carried out once a year in spring. Our gradual-release fertilizer is liquid and specially formulated for maximum plant growth. 

Seed application

Is your lawn slightly bare? Want to increase its density? Groupe Jardins offers a seed application service. Our trained technicians will come to your home and apply quality seeds to give your lawn a healthier appearance. Ask us for our rates. 

Crabgrass germination treatment

Preventive treatment applied early in the season to partially prevent crabgrass germination. Crabgrass tends to grow along curbs, parking lots or in sparse areas of your lawn. Being in the same family as lawns, herbicide treatments have no effect on this undesirable plant. Crabgrass is a highly competitive annual that will die back in the fall. You’ll notice its reddish-brown appearance in late summer. However, before it dies, it will form seeds to reseed itself late in the following spring. 


Yes, a lawn is a plant that needs to be fed every year. Our nutrient solutions for lawns provide all the major (nitrogen, phosphorus, and potassium) and minor (calcium, magnesium, zinc, cobalt, aluminum, manganese, copper, etc.) elements, as well as trace elements (iron, sulfur, etc.) needed to keep your lawn healthy.

From 4 to 6 weeks, depending on the time of year and temperature. Ideally, when installing a sodded lawn or a lawn with seedlings, a fertilizer with a high phosphorus content should be incorporated into the soil.

After a few days, you'll notice that your lawn has turned green and that weeds have died back, if herbicide has been applied. What's more, unlike many companies, our technicians don't have a daily quota and are paid by the hour, so they have no interest in cutting corners.

Many factors can contribute to the yellowing of a lawn: insects, disease, hot weather, drought, excessive humidity, physical damage, etc. At Groupe Jardins Brossard, service calls are free for our customers. You can even count on the services of an agronomist.

Several factors can explain this phenomenon (other than the proverbial). Often, it's a question of cultural practices (cutting height, irrigation, spring preparation, aeration, etc.), soil type and the quality of the lawn at the time of establishment.

These are often areas where the lawn is sparse and winter damaged. In addition, very warm temperatures and sometimes a lack of soil under the lawn stimulate weed growth. Weed seeds, such as crabgrass, therefore have sun and space to grow.

The presence of skunks or birds is probably due to a population of grubs living under the lawn. If there's any excavation, you can be sure of the presence of these destructive insects.

Yes, if you want a beautiful lawn. There are three types of grubs that are a problem in our region. The most devastating for lawns is the European chafer. It has a life cycle of 1 year. Egg-laying begins in July. We see the first larvae towards the end of August. You'll see damage in the fall and especially in spring from skunks. If there is damage to your lawn or to those in your neighborhood, we strongly recommend treatment. What's more, if your lawn is new or to your satisfaction, it's a good insurance policy for a few dollars.
