Wide open spaces of lawns are lovely, but they take lots of work and resources. They cannot just happen. In Australia, we have the added complication of hot dry summers which most lawns don’t like. Lawns need lots of water, nutrients and time. Lawns are cooling, help us relax psychologically during summer and certainly are a great destination for a sit and have fun. Our youngsters and pets love lawns, especially to roll and play on.

Many gardeners dream of a smooth green lawn but don’t know what maintenance techniques are involved to achieve this look. This short article is going to allow you to in to the tricks of the trade and assist you to produce a beautiful green lawn.
You can find two kinds of grasses cool season and warm season and they both have good and bad points. Cool season grasses such as bent, rye or fescue like temperatures between 10-20C and have two growth periods – autumn and spring. They’re lovely and green over winter but they often go brown over summer. It is difficult to keep them green over summer and they might require lots of water. They have a greater leaf, aren’t as robust whilst the warm seasons grasses and don’t seem to get involved with the maximum amount of trouble of warm season species. Cool season grasses multiply by seed or by producing more tillers around the first shoot that comes from the seed. A tiller is the newest side growth, right close to the parent plant.
Warm seasons grasses this kind of buffalo, couch and kikuyu like warmer temperatures (20-30C) and often die down over winter in colder areas. They like tropical humid conditions and keep their colour over summer. They’re drought tolerant and can tolerate neglect. But they’re very vigorous and get can enter all type of mischief. Warm season’s grasses spread by stolons and/or rhizomes. Rhizomes are in fact compressed stems and among the big draw backs of these types of grasses are which they grow under the ground into your flower beds. Underground runners are very hard to have rid off while they constantly grow back. Warm season grasses are much coarser and can be prickly to sit on. They tend to develop thatch over time.
As with all plants, the roots need oxygen and compaction is often the major trouble with lawns. Compaction is when the soil particles are pushed together and the moisture and oxygen can’t penetrate the soil. This often happens in high traffic areas like the way to the clothes line. Compaction causes the grass to struggle and weeds to thrive as weeds can cope with soils with low oxygen. Compaction also causes bad drainage, steering clear of the water from soaking into the top soil and moving down profile. Puddles are caused by either the pore spaces being filled with water, or the particles are so closely packed together, the water can’t filter through. The grass literally drowns since there is no oxygen!
