How to improve drainage in turf & lawns

If you are starting a new lawn, or if you are improving and old lawn, the first place to start is to look at your soil and drainage.   Drainage will affect how well your lawn grows and also maintains consistency of growth across the lawn area.    Generally speaking, you want to have nice consistant growth across the lawn, and avoid damp spots.   When preparing a new lawn it is best to investigate the soil already in place, can it be improved? or do you have to bring in new soil to start your lawn on.  Does the area drain well? or do damp spots develop when under heavy rain or irrigation. 

If you find that your have a perennial problem with bad drainage there are a number of things you can do.  1.  Your soil may already drain, but is slow draining.  You can contour the land in this situation, so that excess water drains somewhere else.  This means making changes to the levels of your lawn so that the water is redirected, so it does not pool.  2.  You can change or improve your soil type so water is directed deeper into the soil profile.  3.  You can use underground drainage techniques like Slotted Hose, which is also called Agricultural line.  To capture water and redirect it.

If you find that your soil is too well drained as occurs in sandy soils, then you will need to look at ways to improve the soil to hold more water.
