Well spring is upon us and if you have ventured out and looked at your lawn you probably see some moss in it.  Moss is always a problem in the Willamette Valley. You can never get rid of it, but you can control it. Most people wait until spring to treat it. The problem with that is it’s too late and the damage has already occurred. Moss control must be done before the problem gets a foothold. Apply moss killer during the winter months every 30 days and anytime you see some growing. Moss killer can be bought in a number of ways, both granular and liquid. The powder form works the best but is messy to apply so I use the granular form because it’s the easiest to apply. Be careful there are different types of moss killers. Use one that is listed for grass. Iron Sulfate is the best. It can be bought in little 3 lb. cans or in larger bags up to 50 lbs. The large bags can be found for less the $20.00 and are by far the best way to go. When you apply it be careful not to get it on any concrete surfaces as it will stain them.  Applying it in your flower beds is also ok. Some fertilizes come with moss killer in it. The problem is it doesn’t really have enough in it to do any good. Iron sulfate also helps to give you a darker green lawn.

Now for those of you how have waited too long and now have more moss than lawn. You have a few choices. Replace the lawn or try to save it. If you want to save it, try this. Apply the moss killer at twice the rate listed. Wait for it to turn black, then rake out the dead stuff. Rent a power thatcher to save yourself a lot of work. Now that all the moss is gone you have a lot of bare ground and a little grass,  you need to re-seed the area. Make sure you chose the right seed depending on the amount of shade or sun the area receives. In this area rye grass is mostly used but fescue’s work better in shady area. Now cover the seed with sawdust or fine mulch. This helps in a couple of ways. It hold’s in moisture and hides the seeds from the birds. Now apply a seed & sod starter fertilizer. Something like Scotts Starter Fertilizer for New Seed and Sod/20-27-5/5000 sq./ft. Just be sure the second number is high because that promotes the root growth. Now two more things, the ground temperature needs to be 50 degrees for the seed to sprout very good. Next never let the seed get dry. If that happens 50% of the seed will die.
