_____________________________________________

After any invasive treatment such as scarifying, you should always assist the lawn to recover. This is easier if you’ve been wise with your timing and nature is helping by providing some warmth, sun and rain to speed things along.

As far as I’m concerned the lawn is there for my benefit and I want it to look respectable all year round. You should be able to achieve the same regardless of whether you’ve got a kiddies play lawn or a masterpiece. Just get your timing right!

Firstly, if you have or had moss in the lawn a dose of ferrous sulphate* based moss killer*, preferably by watering can or sprayer will kill any moss left in the lawn. It should penetrate deeply into the moss now that you've thinned it with your raking. This is one of the best ways of reducing moss infestation.

Secondly, get some fertiliser into the lawn. I always use a fertiliser containing potassium  and any of the Lawnsmith fertilisers will do as they all contain potassium. This helps the grass fight off the stress of the scarifying and will help protect against disease. As most of your scarifying activity is going to be in August or September you'll find an autumn fertiliser like Lawnsmith® AUTUMN Lawn Feed* is an ideal recovery fertiliser.

If you are scarifying in spring you could use Winter Green High Iron Lawn Feed* as an alternative to ferrous sulphate and a fertiliser. Putting this on the lawn at the higher rate will also blacken the remaining moss and as it contains nitrogen and potassium will go someway to aiding recovery of the grass. Make sure moisture levels are good before using.

Thirdly, add lawn grass seed*. If damage is patchy then a light sprinkling (10 to 20 seeds per square inch - no more) into those areas may be all that is needed. However, if you’ve done a thorough de-mossing or de-thatching then it’s risky to expect a full and uniform recovery so get some grass seed into the whole lawn. The fertiliser will help the new seedlings but if the area you are seeding is virtually bare you could even use a pre-seeding 'STARTER' fertiliser* which gives an extra bit of wumph to new seedlings.

If you’re going to be using iron sulphate or an iron fertiliser AND over seeding put the seed in at least a couple of days afterwards. Other fertilisers can be applied at anytime but preferably just before or at the time of seeding. 

Finally, pray for gentle rain and be prepared to get the sprinkler out if you’re the unlucky sort!
