How To Get Rid Of Yellow Patches In Your Lawn

You've noticed a few yellow patches in your yard, or spots where your lawn could use a boost? Seeding in the spring takes longer due to the cool soil temperatures. Ideally, the daily temperature should be between 15 and 20 degrees Celsius for at least two weeks before overseeding. This will allow the soil to warm up to the optimal temperature for seed to germinate.

Germination does not usually occur until mid-May, sometimes a few days later, depending on the place you live. When nights are cold in the spring, the soil is slower to warm up. Seeding in the spring is thus highly influenced by weather conditions.

Late summer or early fall is the best time for seeding grass seed. You will need a minimum of 4 to 6 weeks of good growing temperatures, during which the daily temperature will stay above 10 degrees Celsius for optimal germination. This means that grass seed must be applied before mid-September, here again depending on the climate in your region.

The more northern your region is, the earlier you will need to sow the seed. If grass seed is applied too late, it may not have enough time to germinate and grow before the winter, and it is likely to die from the cold and frost.
