Maintaining a healthy lawn involves using good maintenance practises during the growing season. Proper mowing, irrigation, fertilizing and thatch control provide a dense, healthy, high-quality lawn.
- Keep your mower blade sharp to avoid leaving ragged brown edges on grass blades.
- Set your lawn mower wheel height at 7.5 cm. Mowing at a higher height promotes vigorous grass growth with deep root systems which in turn, discourages weeds and insect pests.
- Mow your lawn when it reaches 11 cm high, this will remove the top third of your lawn's height.
- Provide 2 to 3 cm of water every 7 to 10 days togrowh healthy lawns with deep roots.
- To measure how much water your lawn is getting place a flat pan under the sprinkler. When the water measures 2 to 3 cm stop watering.
- Watering lawns in the early morning hours during which the sun is low on the horizon and there is little to no wind reduces evaporation losses.
- Lawn watering should be gradually reduced in early September.
- If you have low spots in your lawn, you can fill in these areas by adding a half a centimetre of soil or compost twice a year over several years. Avoid adding so much soil/compost when topdressing that you change the overall grade of your lot.
- If required, spread up to half a centimetre of soil or compost on top of your grass annually to increase soil depth. By adding this thin layer of soil or compost over your lawn, you add beneficial micro-organisms to help break down thatch.
- You can topdress and reseed areas where your lawn is spotty each fall (also know as bald spots.) Remember grass will always be spotty under evergreens or in the shade. In these instaces, removed the grass and establish plants which can tolerate these growing conditions.
- Combined fertilizer and pesticide products are not recommended as it spreads pesticides over the entire surface of your lawn.
- Too much fertilizing can lead to thatch build-up. One of the best ways to fertilize your lawn and help the environment is to leave your grass clippings on your lawn (also known as grass cycling). Grass clippings are a free source or nitrogen for your lawn, and can provide about 30% of your lawn needs.
- You can also top-dress your lawn with compost or steile, aged cattle or sheep manure to provide nutirents.
- Aerate your lawn in the spring or fall if your lawn seems compacted. You can also aerate your lawn before fertilizing to help nutirents to seep into the soil.
- Use a core aerator on your lawn that removes plugs of soil and grass from your lawn.
- Aeratings benefits your lawn by allowing water, oxygen, and nutrients to reach your lawn's root system. It also helps control thatch.
- Check the amount of thatch your lawn has several times a year. (Thats is the brownish yellow layer made of dead plant material which is found between the green grass blades and the soil. It prevents water and nutrients from seeping into the soil.)
- To remove that layers thicker than 1.5 cm, use a rake. Use vertical mowing or core aeration to reduce a very thick layer of thatch layer.
