A Good Time to Renovate!
Lawn renovations can be done a variety of ways, depending upon the initial condition of the lawn, the desired outcome and the budget.
If you are seeding a lawn, here are few things to remember.
Seed / Soil Contact is Essential
In order to get good results with any lawn seeding project, the seed must be in contact with soil. If seed is simply sprinkled on the surface of a lawn with an excessive thatch layer, the seed may germinate, but the tiny roots of the newly germinated seed will never make it to the soil, and will die during the first hot dry period. Seed must have good seed to soil contact.
Starter Fertilizers Enhance Seed Establishment
Starter fertilizers help the newly germinated seeds get an abundant supply of phosphorous, even though they initially have a small root system. The nitrogen component is usually small in order to encourage root development as opposed to leave growth.
Our Organics Plus Topdressing has an abundant supply of natural phosphate that is slowly available to the newly germinated grass plants.
Use the Best Grass Seed Available
Avoid saving money on grass seed.
Buy the best seed for the environmental conditions found in the landscape.
Use a seed mixture, as opposed to one cultivar.
A variety of grass seed species and cultivars results in good biodiversity within the lawn.
Good biodiversity results in a lawn better able to tolerate environmental stresses.
Use certified seed selected to address specific disease or insect resistance, as well as environmental factors like shade or drought.
Correct Soil Compaction and Soil pH
If the soil is compacted, or suffering from an acidic pH, make sure these issues are corrected. Soil core aeration and liming must be done in order to ensure good seed establishment.
Maintain Good Topsoil Moisture- WATER!
Water daily until the new grass plants is established. It generally takes about a month for new seed to germinate and get established.
A newly seeded lawn needs to be watered daily in order to ensure good establishment. The newly germinated seeds have tiny, shallow roots and will die quickly if the water supply runs out. Light irrigation (1 cm of water) daily is all that is required. Avoid heavy irrigation as this can result in pooling of the water, erosion, and leaching of valuable nutrients below the root zone.
The following is a description of several approaches to renovation to help you decide what is best for your lawn.
Sometimes a lawn is not easily salvageable due to poor topsoil, an excessive thatch layer, or heavy infestations of undesirable grasses, weeds or disease. In many municipalities across Canada, the use of weed controls have been banned, making the selective removal of undesirable weeds extremely difficult. In these situations the best approach is often a major renovation involving the physical removal of the old sod using a sod cutter, followed by trucking in new soil/compost, and then seeding, fertilizing and topdressing. The old sod is placed in a commercial disposal bin and sent to the municipal composting facility.
This is an expensive renovation, but it results in the creation of a beautiful healthy, weed free lawn consisting of a mixture of premium certified grasses, without the use of synthetic pesticides.

Lawn Rejuvenation / Makeover
A lawn rejuvenation is recommended where the existing lawn is thin and weak, with minor weed infestations, or suffering from minor disease.
The lawn is aerated to break up any thatch layer, reduce soil compaction and open up the soil to improve seed / soil contact. Seed and starter fertilizers are applied, followed by a power rake which smashes the soil cores further enhancing the seed / soil contact which results in improved grass seed establishment. This is followed up with a topdressing that acts like a mulch and provides a slow feeding of nutrients to the newly germinated seeds.
Where allowed, pest controls are used to selectively control problem weeds or insect prior to beginning the rejuvenation.
In coastal regions where moss is a problem, additional work is required to control or remove the moss. Applications of lime to balance the soil pH are also generally needed in these coastal regions.
