If you recently seeded your lawn with new grass seed, but it is not showing signs of healthy growth, obviously something is wrong. Generally, grass is not among the more difficult things to grow, but it does require certain criteria to grow properly. Depending on the climate in which you live, your landscaping and the care you take to promote the growth, your grass will respond differently. Knowing the best approach for producing a green, healthy yard will save you time and frustration.
All grasses are not created equal. They grow at different times of the year and are suited to very different climate conditions. Make sure you are matching the proper type of grass with the climate you live in. Otherwise, the grass will not grow. Also, you must plant your species of grass at the right time. If you live in a mild climate, you will likely be choosing a type of grass known as cool-season grass. Ask someone at your local seed store what types are suitable for your area. Cool season grasses grow in the spring and you must plant them in the late summer or fall. You may plant some varieties in very early spring. Warn season grasses are better suited for places with hot summers. These grasses grow later in the year and require late spring planting.
Poor Soil Preparation
The soil must be prepared in advance of seeding to give you the best chance at good growth. You should loosen up the soil several inches deep and mix in any soil brought in from elsewhere thoroughly with the existing soil. Do not overseed the area for a new stand of grass or it will cause the individual grass blades to compete too much over available soil and nutrients, which could damage all of the grass and prevent it from growing well.
Not giving your grass seed a proper first watering could prevent it from growing. This step is among the most important parts of growing a healthy lawn from scratch. You should water the soil gently and apply enough water so that the top 6 to 8 inches of soil are damp to help settle the seed into the earth and get it in the prime condition for germination. Water the seed gently to avoid washing it away or creating puddles on the ground. You may need to apply water several times in a row to get the desired moisture, depending on the soil's ability to drain and its make-up.
If you've ever noticed that many lawns have bare spots with little or no grass under trees, there is a good reason for this. Grass seed needs sunlight. If shade trees cover your lawn, forming a canopy that lets very little light hit the ground, you will have a lot of trouble getting a thick stand of grass to develop. If your seed is not growing in shaded areas of your lawn, this is most likely the reason.
