Scarification is often done mechanically, thermally, and chemically. The seeds of many plant species are often impervious to water and gases, thus preventing or delaying germination. Any process designed to make the testa (seed coat) more permeable to water and gases is known as scarification.
Scarifying is normally carried out in autumn or spring. When scarifying or de-thatching, not all thatch should be removed as a small amount of thatch is beneficial to the lawn. A lawn that has excessive thatch may feel spongy when trodden upon. After removing thatch, it can be swept or raked up using a lawn sweeper.
This does not happen in the spring. The latest you can safely seed is mid-October. Waiting longer comes with the risk that the season ends early before the grass becomes established in your lawn.
a) Reduction of logging slash, plant competition, and humus prior to direct seeding, planting, scarifying or in anticipation of natural seeding in partially cut stands or in connection with seed-tree systems. b) Reduction or elimination of unwanted forest cover prior to planting or seeding, or prior to preliminary scarification thereto.

Here are a few recommendations on protecting your yard during a heat wave.
On top of the gradual growth of the plant, the image reveals the true meaning of phototropism and cell elongation, meaning the light energy from the sun is causing the growing plant to bend towards the light aka elongate. Plant growth and development are mediated by specific plant hormones and plant growth regulators (PGRs) (Ross et al. 1983). [10]
The pros will tell you that late summer is when you should plant grass seeds, whether you’re starting a new lawn or nurturing an existing one. But there’s a lot more to late-summer lawn care ...
