Hello all, im new to the helpful gardener and lawn and gardening in general, took a horticulture class and learned some basics, but that was ten years ago, hehe. Anyway, I live in what i would say is mid west texas, and just purchased a new house and planted a new lawn. I didn't do any soil testing, and just took some general advice from friends and family and a little of my own to plant some bermuda grass. here are the steps i took.
1 raked the soil and broadcast spread a lawn starter fertilizer ?-?-? and went double coverage with the seed then raked back over it.
2 watered 2-3 a day for 30 min, 30 min, and 1 hr (morning, lunch, and evening). after about 10 days it started coming up.
3 after about 3 more weeks of steady watering it was time to mow and during the 3 weeks i noticed 2 small yellow spots start to form in my healthy lush grass and i also noticed the water kinda pooled up in these spots, but due to the texas heat they never lasted long after i turned off the water
4 1 week after mowing the yard its due for another cut but i just noticed the spots are looking 2-3 times bigger now. and here i write asking for advice.
could it be the h2o pooling, iron deficency, fungus, and what is a cheap way of determining and solving my problem, thanks for any advice and good day to ya.
