Gardeners love all things green and what bigger piece of green is there on your land then your lawn? Grass is after all blades or leaves that need to be cut, protected from pests and weeds and fed and watered. All things that a gardener does in his garden he can do for his lawn.

 
There are many special lawns that professional gardeners tend to include golf courses, ornamental lawns, and even sports turf.

 
There are many more tasks for the gardener to tend to besides cutting the grass to keep the lawn in tiptop shape. Gardeners contend with brown spots, moss in the lawn, pests such as leatherjackets, and ants, moles, bees and even dogs.

 
Female dogs commonly cause brown patches. To repair, you need to keep the dog off the area, and water well so that her urine gets soaked into the ground. The grass does not always recover, but it is worth a try.

 
Bare spots are usually the result of a poorly adjusted lawn mower that causes "scalping" of the lawn. Raise the height of the mower blades.

 
If you have moss in your lawn it is your lawn's way of saying, "heh, something is wrong with me". Killing the moss without fixing the cause of the moss will result in more moss showing up that you then have to deal with. Causes of moss in your lawn may be: the lawn being too waterlogged in the winter and summer months, poor feeding (light green grass), acid soil, too much shade from trees or large shrubs and mowing your lawn too close. Droughts can cause moss and so can sandy soil because it does not allow the grass to drain well. Too high of traffic (too many kids, pets etc.) can also cause moss. Correcting these causes can correct the problem, so when you kill the moss it will stay away.
