What to do After Getting Rid of Moss
After any invasive treatment 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 or MossOff moss killer, applied by watering can or sprayer after raking 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. If you applied ferrous sulphate prior to raking ensure at least 4 weeks between applications if using it twice. MossOff can be used without regard to leaving extra time.
Secondly, get some fertiliser into the lawn. I always use a fertiliser containing potassium (all Lawnsmith fertilisers contain potassium) as this helps the grass fight off the stress of the raking and will help protect against disease. In addition a fertiliser for sandy soil, even if you have clay soil is most beneficial when seeding as it contains more of the nutrients required by young seedlings.
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 then put the seed in at least a couple of days afterwards. Other fertilisers can be applied at anytime but preferably done at the time of seeding.
Finally, pray for gentle rain and be prepared to get the sprinkler out if you’re the unlucky sort!
Mow the lawn on a normal schedule to keep your original grass from over powering the seedlings. Mow high, with sharp blades on a dry day.
