Buffalo grass lawn in heavy seed
The Reason For Lawns Seeding
All lawns will seed, it's the natural means by which many lawns may propagate itself into a new generation. The seeding can be very different in all lawn types. For example, Buffalo grasses will produce a thick heavy seed stalk and head, Kikuyu seeds are so fine, you need to look hard to see them, and Couch seeds can be fine, easily seen, and produce in abundance.
Will The Lawn Seeds Produce A New Lawn
If you have a newer lawn variety it could possibly be a hybrid, though these lawns are still rather rare. What this means is that the lawn and its seeds are both sterile, and for this reason the seeds cannot propagate a new lawn. The only means of propagating or starting a new lawn with hybrid varieties is to plant runners from a parent lawn.
Buffalo grass has always been notoriously difficult to propagate from seed, and this is why Buffalo is always started from either grass runners, sprigs, or roll on lawn.
Self seeding of new lawns can produce hit and miss results, so it's always best to purchase new lawn seed in the variety that we want, or to otherwise buy new roll on turf - which sometimes may not be available as seed.
Excessive Lawn Seeding

In some lawns, heavy seeding can occur in an abundance and very quickly.
Lawns may do this when they enter into a state of shock, something in its environment or lawn care has changed, and the survival mechanisms of the plant have activated. Instead of using its energy for it own health and growth, the lawn senses that it may be about to die, and uses all of its energy to produce as many seeds as possible to ensure the survival of the species if it were to die.
So what happened?
The answer can be any number of factors, lack of water, sudden drop in watering amounts or frequencies, lack of nutrients, or a sudden increase in temperature. Anything which may cause stress in lawns can be a cause for turf to go to seed. Many lawn types may also just be highly susceptible to seeding, and these factors are covered in other articles throughout The Lawn Guide.
Lawn Care Solutions
The simple solution to lawn seeding is to mow the lawn and remove the seed heads, put down a quality lawn fertiliser in the amounts listed on the product packaging (and no more), followed by a good watering in of the lawn fertiliser.
Follow this up with a few good deep waterings over the next couple of weeks, and the problem should be rectified. It can be a good idea to figure out what the original cause was and rectify that as well, if possible, and begin a quality lawn care regime.
