Hi, I need help with my grass...It is newly planted seed (since April). We had begun by completely digging out the previous over-grown yard, approximately 6-10 inches of old earth removed, and new soil added. It has been well-cared for, with regular mowing with newly sharpened reel mower blade, regular deep watering, and appropriate fertilizer. I live in a fenced yard, and have no dog. Problem is, there are funny, light green/beige spots on my lawn, and I am wondering what could be causing this? They are not dollar spots so fungus seems unlikely, especially with new lawn? It is not dried out, so what could this be? Is it indeed fungus? Bad seed/blades in the mix? Cat or skunk pee (although no smell emerges from the lawn)? I know it is not fertilizer burn as it has been watered after fertilizing, and the spots were there before recent fertilizing. Have a look at the photos. What should we do to get rid of these and have a nice, consistent green lawn? Any ideas? If not, where is a good forum for grass? thanks!
I suggest a soil test to determine what minerals your soil may be needing. I'm not affliated with Grass Roots, but here is information on how to order a soil testing kit for gathering a soil sample that is tested by an independent turf lab in Ontario that we also use: https://www.grass-roots.ca/forms/order_online.php?action=add&qty_product_1=1 Alan Dudley Turf Logic West Vancouver
The brown patches seem to resemble the effects of Red Thread. Which in fact is a turf disease. Link to some info on Red Thread. http://plantclinic.cornell.edu/FactSheets/redthread/redthread.htm The zebra looking areas throughout your lawn looks kinda like you water too much, and are stressing out the new sensitive turf grasses you seeded. Just a possiblilty. If in fact your lawn does suffer from red Thread, do consider fertilizer. Jim.
Monitoring your watering program is alway important. But yes I would try less water and see if the lawn evens up.
Your lawn would be ideally watered twice a week deeply during hot summer weather. Otherwise, unless you're seeding or laying new sod, overwatering causes shallow roots, nutrient loss, disease-susceptible turf and very severe problems with weeds. Did you use a turf starter fertilizer? O.D. of phosphorus as well as nitrogen may cause patchiness.
