Once the germination process has started, if conditions change, the seed or new sprout is vulnerable and may die. If the seed or sprout dries up, it dies. In most cases and for most lawn seeds, losing a day of watering won't kill you. However, if the soil dries up, and most likely to do so to a sufficient degree, the seed of the lawn will stop its germination process.
Grass seeds will only germinate under ideal conditions, conditions that nature has decided will provide you with the best chance of survival once you have grown into a seedling. Dryness is not a favorable condition. If stored in a cool, dry place, grass seeds can last two to three years, but you may not get the same results as when planting fresh seeds. As the seed ages, the percentage of seeds that will be able to germinate decreases, forcing more seeds than normal to obtain adequate coverage.
It can be difficult, if you're doing enough things wrong. Here's how to do it right. Prepare a soft bed of earth. Mix peat moss into the soil to increase the amount of water it can hold.
Sow the seed on top and keep it watered steadily for 21 days. Remember that because the seed is on the surface, it can dry out quickly. The surface MUST remain moist at all times for up to 21 days. That's why it's easier to sow seeds in spring and autumn when the weather is colder and the soil dries up more slowly.
You can also use one of those seed mulch products mentioned above if you have a hard time keeping things moist. All seeds require moisture and a certain temperature range before they begin to germinate. If it is inactive, the seed can stay for a long time. It's what's happening all the time with windblown grass seeds that will sprout in months and years.
In the case of a patio, if it is not the exact time for nature to take care of it, the owner of the dwelling must intervene with supplementary water in time. If it sprouts, it will only be a few days before it needs watering or rain. If it doesn't sprout, it can last for weeks. Set Up a Timed Sprinkler or Irrigation System — A timed sprinkler or irrigation system is the expensive solution here and needs to be installed weeks before spreading your lawn seed.
Consider how the requirements for watering new turf seeds can be modified for each of the following circumstances. Grass seeds will germinate when soil temperatures reach consistent 55 degrees and air temperatures reach more than 60 degrees. When grass seeds dry out after planting and watering them, the germination process is interrupted, which cannot be recovered. For example, 50 percent of Kentucky bluegrass, perennial roe, and tall fescue seeds will germinate after three to five years of storage under ideal conditions, while 50 percent of creeping curved grass seeds will germinate after five years or more.
Grass seeds will not grow without watering, as soil moisture is necessary to start and maintain the growth process. A box or bag of grass seeds that has been stored in very warm conditions, or opened to humid summer air, will not hold its viability very well. The general rule is that a bag will lose between 10 and 20% of its collective germination rate per year when storing grass seeds. Many homeowners apply grass seeds during the spring months after they rake their gardens and find bare spots, but cold, humid weather can make germination difficult.
Once planted, grass seeds should not run out of water on any day during those weeks of initial growth. In addition, their local experience means they know how often they should water the new grass seeds specifically at their location. For the future, your new grass seed will be better preserved if you store it in a tightly sealed plastic bag or container so that it cannot absorb moisture. Since watering grass seeds on a daily basis is such a critical task for overall lawn development, there are quite a few tools you can employ to make sure it's done.
