First lawn treatment of the year!

Had my 1st lawn treatment of the year this week and starting to show a difference already! Bring on some dry weather so I can give it a trim

 

Was that with GreenThumbs or similar GB ? I am giving mine its first light trim today it is cold but has been dry for 2 days . I am leaving my first treatment of soluble Mosskill and Feed until Easter.

 

I was with Greenthumb up until last summer and have now switched to an independent lawn treatment firm. It was after I observed Greenthumb applying treatments in gale force winds It made my mind up!

 

Thought I'd post a few pics of how my lawn is looking, only 10 days since I had first treatment and starting to look quite good!

Does anybody have any experience of using Sulphate of Iron to reduce worm casts on lawns? If so what's the best method of application, I have read various ways of doing this either by diluting or just spreading by hand.

 

I've never known Sulphate of iron to reduce worm casts only to kill moss. The worm casts are there because the worms are near or have been near the surface. Surely, instead of putting chemicals down it would be better just to sweep the casts off.

 

WhenI apply sulphate of iron as a moss killer I've found it easier to get even coverage by using it in solution at between 4-5 gm per litre per 1 square metre.

Worms don't like the acidic conditions created by sulphate of iron and tend to retreat from the surface, but you'd need to increase the concentration to about 8gm/litre per square metre for it to be effective against worms.

 

Thanks Dave, do you use a pressure sprayer to apply or a watering can?

I have tried sweeping them off but after a bout of rain my lawn can stay damp for days and its extremely difficult to not get them squashed and trodden in. I have a pH meter and the soil is approx 9 which makes it a haven for worms.

 

That sounds incredibly alkaline :( Any chance the reading is incorrect?

 

I use a watering can, mark off the lawn in 1 metre widths with nylon rope and 5 metre sections with canes. I then use a 5 litre can of solution on each 5 metre segment.

 

Last time I took a reading was August last year but I did take a few. It varied between 8 and 9 which I thought was high.

 

What sort of meter are you using and how are you taking the soil sample?

I wonder if it would be worth using one of the cheap test-tube tests just to double check it. It may be that alkaline, but I think its very high, and unless you know that the area where you are is indeed that alkaline I think it would be worth using an alternative test just to prove, one way or t'other, than the meter is OK.
