Did you know? If you mow high, your lawn can act as its own natural weed-killer! Mowing high leaves pesky weeds and weed-seedlings in the shade, blocking the sunlight they need to survive. A common mistake in lawn care is mowing low in the hopes of mowing less often; by mowing low, weeds get all the sunlight they need, and your grass is actually forced to grow faster in its race to reach the sun.
Once a week should do the trick, depending on grass type and climate. It's recommended to only cut 1/3 of the grasses height while mowing. For serious weed infestations, consider mowing twice as frequently. The sensitive growing point for grass is near the soil; for weeds it's near the top of the plant.
Get nutritious soil by leaving clippings on the lawn. If you don't leave, you run the risk of robbing your soil of essential minerals. Over time, your soil could begin to resemble cement: inhibiting plant growth and leaving you with a thinning lawn.
Water deeply. It's time to water when the grass starts to curl — before it turns brown! If you wait too long, you'll need to water half an inch, wait three hours and water an inch. Another way to check on watering time is to stick a shovel into the soil about six inches. If you see moisture: wait. If the shovel is dry: water. Grass roots are deeper than weed roots; by watering deeply and infrequently you force grass roots to establish past the dry zone, where the weeds root themselves.
A healthy lawn starts with healthy soil: thin spots, poor growth, and brown spots can all be signs of nutrient deficiency. Restoring the soil's mineral content can revive your lawn. What Mowtown recommends is testing your soil to see what it needs. Apply the necessary nutrients to the soil to correct any deficiencies. Stay on top of fertilizing, and (depending on your grass type) apply fertilizer twice a year at least.
Don't put up with scraggly plants for fear of hurting them. Pruning aids growth and development. Instead of looking at what you're taking away, look at it as preserving and encouraging larger, more abundant flowers or fruits. Removing injured or diseased branches allows healthy branches opportunity to grow!
