Why Does The Time Of Year Affect Weed Killers
Spring is the best time of year for applying weed killer. This is because you can catch weeds in their pre-growth state, before theyve had the opportunity to sprout fully. Spring has the advantages of being both warm and wet.
Herbicides in weed killers require absorption from the soil to activate. This absorption can only take place if the soil is moist from the rain. Spring being a typically rainy season ensures that the soil is wet enough to soak up the herbicide, which is then taken up by the plant root.
Without any rain, the herbicide solution will sit on the soil, rather than being absorbed by the plant.
Fall is the second-best season because weed killers thrive on the sudden change in weather. Spraying weed killer in October means that weeds will struggle to survive the winter.
However, not all weed killers contain herbicide, and can therefore be used at all times of year. For example, Foamstream is a herbicide-free weed killer. This means its not affected by the levels of moisture in the soil.

Aerate The Soil To Relieve Compaction
If you or your family use the lawn every day the soil underneath can become compacted.
When kids run and tumble on the grass or if you walk on a particular part regularly the soil particles under the grass get pushed together. This squeezes out air and water that grass relies on to grow and prevents any nutrients from being able to penetrate.
It also makes the ground hard so the root zone of the grass cant grow and establish itself.
Again, this results in weak, unhealthy grass that is unable to fight off disease and infestations of weeds and moss.
Aeration is the process of opening up the soil so air, water and nutrients can get to the root zone of the grass.
This is usually done by spiking the lawn or removing cores of turf by hollow-tining .
Its a very simple procedure and spiking is very easy to do. Hollow-tining can be hard work though.
