For many people, a yard wouldn't be complete without a lawn. Lawns provide an outdoor space for family activities and a beautiful foreground for flowers, shrubs, and trees. The following information and tips will help you achieve a healthy, thick, green lawn.
The Important Benefits of a Healthy Lawn
Here are some of the less obvious benefits an attractive lawn:
Our Health Our Environment Our Urban Communities
Controls disease Protects wildlife habitat Reduces energy use and greenhouse gas emissions
Protects against allergens Reduces soil erosion Provides urban green space
Enhances outdoor activities Naturally cools the air in summer Enhances air quality
Watering
Lawns need about 2.5 cm (1") of water per week. A safe bet is to water your grass for about 30 minutes every second or third day. Why? A healthy, green grass plant may be as much as 85% water by weight, and it can lose up to 95% of its daily water intake through evaporation.
Tip: A good watering every few days is better than a light sprinkling every day. Heavier watering encourages the roots to grow deeper into the soil for thick, strong, healthy grass, whereas light watering results in shallow root growth.
Frequently Asked Questions in Water-Restricted Neighborhoods:
Without watering, will I lose my lawn completely?
Not likely, because there should be enough rainwater to keep the grass from dying even if rainfall continues below normal. The grass may turn brown between infrequent rains, but should recover once moisture is restored.
When watering is restricted, when is the best time of day to do it?
In the early morning. Avoid sunny and gusty parts of the day, as both hasten evaporation.
Mowing
Never remove more than 1/3 of the leaf surface at one time and ensure your mower blades are sharp. The ideal mowing height for grass is usually 2.5 - 7.5 cm (1-3"). Raise your mowing height as much as possible to help preserve root systems. The higher grass shades the soil, reducing moisture evaporation. This is a key step!
Tip: Lawn clippings can provide a great source of slow-release nitrogen for the lawn. Remove the clippings only when they are so heavy that they smother the grass completely.
Fertilizing
Just as a balanced diet works best for people and animals, the same is true of lawns - they need fertilizer for sustenance. Lawn grasses live in an unnatural environment - the grass plants are crowded together and compete with each other and with neighbouring trees and shrubs for water, sun, and nutrients. Because of this competition and the unnatural demands placed on lawns, they must be fertilized. When properly fertilized, a lawn maintains good health, colour, and density, and it is more resistant to insects, weeds, and diseases.
What do the numbers mean?
On every fertilizer product you will find 3 numbers. These refer to the amount of Nitrogen, Phosphorus, and Potassium contained in the fertilizer.
1st number = Nitrogen ?> for growth, greening, and plant development
2nd number = Phosphorus ?> for strong root and seedling development
3rd number = Potassium ?> for overall hardiness and increased resistance to disease and weather conditions

the purpose of raking the lawn now is to get rid of dead and tangled-up roots (called thatch), and to aerate the grass (to get oxygen in). this will facilitate the grass to grow deeper and healthier. i do it every spring.
also now is a good time to put in fertilizer with weed killer, as weeds are in their infancy and easy to be boot out.
p.s., if you want to repair the damaged lawn, don't forget to rake the lawn, then put a layer of top soil, then spread grass seed, then lightly rake again.

这里多数新盖的高层公寓都把朝外的一面墙全镶成玻璃(落地窗恐怕好理解一些吧？不过那墙是打不开地:bsmile: )渥太华河边的高层公寓你留心看看，还有运河旁边的那些公寓的顶层，尤其，所谓penthouse们…:blowzy:
