Relative to adults, children tended to use more regions of their brains to complete the word tasks, activating more regions near the back of the brain. At the same time, children showed less activation in some regions at the front of the brain that have been commonly seen in adult studies of word processing. In some brain regions, children and adults showed very similar levels of activation while performing the tasks. This included some parts of the frontal lobe.
Look for a mix of fast- and slow-release fertilizers that will green up your lawn quickly, and feed it over time. In the north, feed in fall and spring. In the south, feed in spring and summer. Don't feed dormant grass (drought can cause grass to go dormant in summer) because it can't take in nutrients.
Depending on where you live, the best time to plant grass may be in the summer months. Warm season grasses need to be planted in the summer since they require warm soil temperatures to germinate and grow. Otherwise if planted in the fall like cool season grasses are, they may still germinate but will most likely fail to make it through the winter season because they will not establish. With proper seedbed preparation and other care practices, you will find it is fairly easy to plant grass seed in the summer.
