Pull out these weeds as soon as you spot them. It's better and cheaper to nip weed growth in the bud, rather than letting the problem go unnoticed. If not checked, weeds can grow rapidly and pulling them out would not be a feasible way to get rid of them. You may have to make use of herbicides which may turn out to be costly.
If at all you have to use them, make sure you read the instructions carefully before applying them. Always water your lawn deeply and fertilize it with nitrogen to prevent growth of weeds like dollar spots and crabgrass. If you spot dandelions and want to clear them from your lawn, spray vinegar on them instead of herbicides.
Lime is sprinkled over the turf to raise pH levels (in the form of calcitic or dolomitic lime), and granulated sulfur is added to reduce the pH level. Very high/low pH levels mean that the grass and plants are not receiving adequate nutrients from the soil in the form of nitrogen, magnesium, sulfur, phosphorus, etc., and this may result in an unhealthy lawn.
Mow the lawn regularly and also trim the growth around trees, gardens, bushes, patios, driveways, and the edges of the yard. Alter the pattern of mowing every week. This ascertains that the lawn does not acquire a set design of indentations and grooves and also prevents soil compaction.
The most important guideline to follow while mowing is to cut 1/3rd of the length of the grass. The ideal height of the grass should be maintained between 2½ to 3½ inches. Taller glass blades act as a deterrent to the growth of weeds.
Let the grass grow slightly taller, especially in summer, it helps to retain moisture and saves you from watering very frequently. Cut the grass with the lawn mower blades set at a high level. Sharpen the lawn mower blades once every three months. Wait for two days to mow the lawn if it has been treated with fertilizers.
Use the mower during the evening hours, to make certain that the newly mowed grass gets a few hours of reprieve from direct sunlight. Also, avoid mowing early in the morning. The dew that forms on the grasses is actually beneficial for it. Mowing will rob the grass from the revitalizing effects of the humidity present in the dew.
If your lawn has cool season grasses, the ideal time to fertilize would be during the fall, and again during spring. For warm season grasses, it's best to fertilize in late spring and late summer. Fertilization strengthens the root system and enhances new growth. Fertilize your lawn twice a year.
Ensure that you use the right kind and amount of fertilizer for your lawn depending on the type of grass that grows. Other than nitrogen, lawns require phosphorus and potassium. Phosphorus aids in seed development and root growth, and potassium builds resistance to diseases.
The best way to know how much fertilizer you need is to calculate the area of your lawn in square feet. The fertilizer bag will contain all instructions regarding the concentration of nutrients present, and how much and when to use it.
Be resourceful and channel the waste water and bath water from your home and water the lawn with it. If the surface of the lawn is very hard and dry, prick it using a garden fork before watering it, which will help retain the water.
Water in the cooler part of the day, either mornings or evenings, so less water is lost due to heat and evaporation. Irrigate deeply, and not too frequently. You can also add soluble nutrients to the water, which will not only nourish the grass, but also kill harmful moss and weeds.
The process of removing the thatch from a lawn is called dethatching. This allows the roots to grow better, and absorb more oxygen and water needed for survival. Though excess thatch is harmful for a lawn, a small layer of thatch can actually be useful.
It holds back the moisture and also provides some shade from direct sunlight. To dethatch, use special dethatching blades that can be attached to the lawn mower. Or use a mower that's designed just to dethatch.
One of the most eco-friendly approaches to maintain a healthy lawn, aeration of the lawn is done by pricking holes in the lawn and is mostly used to break down compacted soil. Sometimes, also referred to as core aeration, this process also aids in dethatching.
Loosening up the compacted soil allows it to breathe by providing it with more oxygen. Nutrients, fertilizers, and water can easily seep deeper into the soil, reaching directly to the roots. Ideally, water the lawn a day prior to aerating it, and aerate when the soil is still soft, but not too mushy.
