It is a wise decision to assist your lawn to recover after invasive treatment such as scarifying. It will be much easier if you are keen with timing and more so if nature could bring in a helping hand with some warmth, sun and rain to speed up the healing process. Using lawn scarifier is important. You need a good equipment depending on the size of your lawn and budget.
The lawn is here for your benefit, and it is your duty to make sure it looks respectable all year round. Regardless of whether you got a masterpiece or kiddies play lawn, you should be able to achieve the best, and it all lies in your timing. The following are to be done after your scarifying.
Things to do
Kill the Remaining Moss
If your lawn had moss and you have done scarifying, applying a dose of ferrous sulphate based moss killer by a sprayer or watering can help kill any moss left on your lawn. As you spray, ensure that it penetrates into the moss because you have thinned with a scarifier. This is one of the best ways of reducing moss infestation.
Speed Thickening and Improve the Density of the Grass
Scarifying can cause damage to your lawn causing some patches. Adding lawn grass seed of about 10-20 seeds per square inch are all that you need to do. But if you have done thorough de-thatching or de-mossing, don’t expect full and uniform recovery so, you better get some grass seed into the whole lawn. If the area you are seeding is bare, using pre-seeding STARTER fertilizer will help a lot by giving the extra seedling jump.
Start Lawn Recovery
Get some fertilizer in your lawn and ensure the fertilizer you are using contains potassium. Alternatively, you can use any of the Lawnsmith fertilizers as they all contain potassium. The potassium will help the grass to fight the stress of scarifying and will contribute to protecting against diseases. If you scarify your lawn in August or September, then you can use a fertilizer like Lawnsmith Autumn Lawn Feed, which will help the grass to recover fast. If you scarify in spring, you can use Winter Green High Iron Lawn Feeds as an alternative to ferrous sulphate and fertilizer.
Note: make sure the moisture levels are good before administering the fertilizer. And if you are going to use iron sulphate or iron fertilizer and over-seeding, ensure you put the seeds in after a couple of days afterwards. You can apply other fertilizers at any time but most preferably just before or after seeding.
