Spring

Spring lawn care is all about cleanup, but you have to wait till the soil is dry. Later on, you can mist once a week to encourage healthy root growth. Application of a slow-release fertilizer is advisable. For warm-season grass, fertilize only when the greens show active growth. Aerate by making small holes in the ground to allow better drainage. Mow when the soil is dry, taking care not to tighten the soil, and eliminate more than one-third of the grass height.

Summer

Summer is a busy period for lawn-mowers. This is the time when you:
-Adjust your mower blade’s height to 3-inches.
-Work in an inch of water per week; lawns do better with occasional watering.
-Assess sprinkler output by tying pins around the lawn to determine water collection in a specific period of time. Use a rain gauge to keep track of natural water supply.
-Clean your mower at the end of the month to destroy seasonal pathogens.
-Rake up leaves and plant debris to fill up compost and prevent the spread of diseases

Fall

Now is the ideal time to lay the groundwork for winter plantings.
-Remove dead grass and fallen leaves.
-Loosen up the soil using a trowel.
-Work an inch-deep layer of compost into the soil.
-Sprinkle grass seeds that thrive on cooler temperatures.
-Spread grass clippings evenly on the to prevent the ground from drying up.
-Go easy on watering until the seeds germinate.

Winter

Winter is when you tend to the cool-season grasses. Fertilizing is important to recycle nutrients and nourish the roots all winter long. Chop off half the height of the grass; else your lawn will invite pesky visitors. Chalk out next year’s planting routine.
