Organic Lawn Care for Busy People: Lawn To Do List Spring
Updated: Apr 3, 2023
Lawn chemicals, synthetic fertilizer and blowing are causing environmental problems, impacting our health, and interfering with soil health and carbon sequestration, and most importantly they are often the cause of lawn problems.
You have the option of doing nothing at all, which is less harmful, but not ideal for your soil and for your lawn. Resourceful weeds are likely to take over.
Expectations:
You can have a pretty lush lawn without chemicals and blowing. You will need to get used to having some "weeds" in your lawn. There are benefits to some amount of weeds: Clover provides nitrogen, while other common weeds like, violet and dandelion support honeybees and other pollinators. As for grubs and other enemies of a lush lawn, the best defense is to maintain a healthy lawn and yard environment to encourage predators including birds and other insects. Here is how we suggest you do that:
1) Get a nutrient and pH test of your soil:
There are number of good soil tests out there. Soil Savvy - Soil Test Kit is available on Amazon. The test will provide information needed to adjust pH and fertilizer.
2) Apply organic fertilizer mid April and mid September in New Jersey.
Organic fertilizer supports ability of lawn to complete with weeds. Organic fertilizer provides slow-release nitrogen and other essential nutrients.
An alternative is corn gluten meal, an organic weed control that works by preventing weed seeds from sprouting.
Corn gluten is protein byproduct from the production of corn syrup, used mainly as animal feed. Corn gluten breaks down after several weeks into a slow-release nitrogen-rich organic fertilizer. Timing of application is important. Put it down in early spring, about when first crocuses are blooming. Wait six weeks before putting down any grass seed, which will also be killed by the corn gluten unless you wait until after it has broken down.
3) Get You Lawn Core Aerated.
If your lawn is in pretty good shape, core aeration is needed in the fall only (mid September). If you starting with lawn in rough shape in the spring, core aeration should be done in the spring as well.
Fall is best time for a core aeration to help loosen soil compacted by summer foot traffic and to promote root growth. Most lawn services do aeration. Make sure the lawn is well watered beforehand.
4) Reseed Bare Spots Spring & Fall
Fall is best time to reseed bare patches. Success will improve if you cover seeded areas with chopped hay and keep those areas watered until the new grass is well-established. Best and most drought tolerant seeds mixes contain a lot of tall fescue. High quality rye grasses sprout quickly. Mid September is best time for seeding, however reseeding in May is good idea if there are a lot of bare spots.
Ongoing Care
Water only when grass is dry and when you water, water deeply.
Keep track of rainfall with a rain gauge and if your lawn gets thirsty, water deeply, putting down at least a half inch. Light frequent watering does more harm than good b bringing roots up to the surface and causing thatch.
Mow High
Set the mower for about three to four inches. The higher turf level tends to deny sunlight to germinating weed seed. During damp cool months of spring, you may need to mow more than once a week. The higher frequency makes it less likely you are cutting down on the stem of the grass plants, which stunts their growth.
Leave the clippings behind.
They recycle their nutrients back into the soil.
Minimize blowing.
Not only is blowing very noisy and polluting, blowing harms the soil by stripping nutrients off the lawn.
Mow leaves in.
Like clippings, they recycle nutrients back into soil. A rotary mower works well for this purpose by partially shredding leaves to speed their breakdown.
