Hi,

Does anyone have experience with the Echinochloa crus-galli?

My lawn has been seeded in March, everything was perfect until the spread out of this graminacee called Echinochloa crus-galli.

iIt seems very very common in the region where I live. I tried so much to eradicated them but with no results. I’ve fear that could conquer all my lawn soon.

thanks

    I think that you need to mow regularly, as soon as the intruder is taller than the lawn grass mow it ... not too short or the grass roots will be exposed to too much sun and heat.

    If you've correctly ID'd it as Echinochloa crus-galli , then mow it regularly to eradicate from your lawn .
    It is an annual species so prevent it from flowering in August/September ; this should resolve your issue .

    Hi,

    thanks for your suggestions.

    I mow the lawn last Sunday evening. I decided to keep the lawn at 4 cm, 1.57 inch (before was 3cm, so 1.18 inch). This is because there are 34/35 C’ degrees during the day.

    To me it seems a little bit better, even if our intruder friend grows with a triple rate. Do you suggest to mow again starting from today or to wait at least one week, so on next Sunday? Some pictures attached taken this morning.

    I would ... I’d mow as soon as it pops above the level of the surrounding grass, if at all possible. 

    Good luck 😊
