It’s Spring! I’m sure everyone is probably anxious to get out into their yard and spruce it up for the summer season to relax and enjoy. If you’re thinking of fertilizing your yard though – STOP!
Spring is not the time to fertilize. The best time to fertilize is in the Fall, so your root system can develop strong roots to crowd out any weed intruders.
What you can do in April is add lime if needed (have a pH test done to determine if this is necessary) and reseed bare spots making sure you rake the seed into the soil for good contact.
Seed mix: One good seed mix for the northeast is 65% Kentucky bluegrass, 20% fine leaf fescue and 15% perennial ryegrass. Depending on what your demands are on your lawn, will depend on the seed mix you should use. Keep in mind the sun requirements: shade mix needs at least 4 hours of direct sun, and sun mix needs at least 6 hours of direct sun. Of course, you can always reduce your lawn and add more gardens. J
If you didn’t fertilize in the Fall, your lawn may benefit from fertilizing now. Keep in mind though, that Spring fertilizing greens up your lawn fast, but you have a shallow root system which allows weeds to come in. The best defense against weeds and crabgrass is a healthy lawn with a good root system. You are also more likely to see lawn stress in the summer from lack of water, due to the shall root system. If you want a more organic way of fertilizing, try “compost tea”. http://www.countryliving.com/outdoor/gardening/compost-tea-0808 and http://www.comfylawn.com/lawn-compost-tea.html
You can remove broadleaf, dandelions and onion grass by hand using a trowel. If you have a problem with crabgrass, you can apply a pre-emergent crabgrass killer when the forsythia bushes are in full bloom, but this does contain chemicals, so be wary.
Mowing: Begin mowing your lawn when the lawn height is the height it will be maintained at (approx 3” or higher). Use a sharp mower blade for a good cut, and leave the clippings on the lawn to allow the nutrients back into the soil. Do not leave “clumps” of grass on the lawn. When mowing, you only want to take off 1/3 of the leaf (grass blade). This will help maintain a healthy lawn by allowing roots to develop, and water and nutrients to be absorbed from the soil. A good rule is: mow your lawn at the height of 3” to promote a good root system.
Fertilizing: Lawns need nitrogen for a healthy lawn and good root system. Fertilizing is best done in the Fall when the grass has slowed growing, so that all the nutrients are provided to the roots to develop a good root system. If you have winter injury to your lawn, which is unlikely here in the southern NY area due to our mild winter this year, or did not fertilize in the Fall, your lawn will benefit from fertilizer once the soil temperature is above 55 degrees Fahrenheit. Just remember in the Fall to add 50-75% nitrogen between August and November, when the shoot growth is slowing and the root growth is increasing.
Watering: Your lawn needs water. You should water in the morning, when there is less evaporation, and do not “over water”. If you see water running off of your lawn onto the hardscape, any pollutants present are being carried in that water into our storm drains. Your lawn is a “filter”. It filters all the rainwater before it goes into our water table. Added pesticides on your lawn are not only bad for the wildlife, pets & children while they are walking on it, but it can go into our water system as runoff when we water our lawn or it rains, and harms our aquatic life and ultimately all of us.
Aerating: Should be done in late summer/early Fall.
In summary: A healthy lawn will attract birds, butterflies, dragonflies, and all beneficial creatures, that will aid in keeping your yard in balance – naturally.

BTW…if you have the occasional dandelion (and don’t use pesticides), dig it up and add the tender leaves to your salad. Dandelions are extremely nutritious and full of vitamins. Check out the below link: http://genuineaid.com/2010/11/12/dandelion-nutrients-and-benefits/
