Lawn Leatherjacket Damage
For the third consecutive year my lawn has sustained significant leatherjacket damage. I use the services of Green Thumb to look after my lawn but I'm really questioning whether I should continue. Whilst it seems ridiculously cheap (4 quarterly visits at c£17 per visit - lawn is approx. 100sqm) I don't seem to be making progress. They have sprayed at least twice for leatherjackets but it doesn't seem to be effective. They also seem to rush everything they do - which is no surprise at £17 a visit, they can't be making much money. I guess our recent warm, wet winters have done nothing to knock back the leatherjacket population?!
I've read a lot about nematodes. Is this the best course of action on a DIY basis? One of the reasons I employed Green Thumb was that at my previous house I twice managed to burn the lawn badly when applying feed.
So, I'm going to be re-seeding significant parts of the lawn when the weather picks up. I will need to cover it with netting as the pigeons love it when I've had to do it in past years. I try to look after it - aeration through deep forking and light 'scarifying' with an electric lawn rake. Does anyone have any pointers to a nice simple scheme of what to apply and when?
