Johnsons Lawn Seed’s new formula features tetraploid ryegrass, whereas previous formula only featured a diploid variety.
The terms 'diploid' and 'tetraploid' ryegrass refers to the number of chromosomes per cell in the grass plant.
Diploids have two sets of chromosomes per cell while tetraploids have four.
Anyone who remembers their school science lessons will know that the extra chromosome provides not only a bigger cell size, but also supplies more energy to the seed. This extra energy, when planted, is expended within 10 days, delivering quicker germination rates.
The extra energy also provides deeper roots, which explains why grass grown from a tetraploid seed requires less watering and feeding.
Deeper roots also come into their own during periods of drought as they have the capabilities to locate water from sources far below the surface.
Extra energy also means that the new formula mixes from Johnsons Lawn Seed are almost fool-proof. Many people suffer from lawn seed failure as a result of burying the seed too deep.
The poor little seeds do not have enough energy to break through to the surface, however in the case of the tetraploid new formula, this problem has been combatted.
The extra energy delivers the grass shoot to the surface, whilst driving the roots deeper for a much firmer and permanent rate of establishment and development of a long-lasting, hardwearing lawn.
