If the soil is moist to that level, it is very possible you are over watering. Even if the water is not a source of the problem, you are wasting water. You do not want the sod to be "squishy" when walked on. How long are you watering each time? What have been the daily high and low temperatures since you laid the sod? Look at your grass blades for signs of disease like lesions and fungus. Google for images and descriptions of KB turf diseases and compare those pictures to your blades. How did you prep the soil? Did you add amendments? What amendments? How did you incorporate the amendments? How long before you laid the sod?

Thank you My hugonis is on the corner next to a fairly busy road. Deer avoid it because it is too close to the habitat of their fiercest enemy, the F-150. However, there is an enormous R. cantabrigiensis nearby that is accessible in a garden where other roses are carefully fenced in. It's the size of a one-car garage. So it doesn't look like they are favorites, but if they get a chance to mature, the deer won't be able to reach most of them due to sheer size. I must warn you, though, it isn't an easy rose to root. Tree peonies may last two weeks here if we don't get a heat wave. They are planted on the south side of a big oak tree, so they get morning and afternoon sun, but are shaded midday. I have two kinds of lilacs. Syringa vulgaris, the old fashioned usual kind, which were here when we bought the house. And Syringa microphila, which is next to the driveway. Unlike most of the roses, this one sometimes repeats.

LOL tj! I can't believe that many are not yellowing for you. I can also understand being leery paying any money for another mellow yellow though. You have other colored plants there so something is not right about this whole bunch and I am wondering if maybe they were gotten at the same place. You know I've even read on here about making sure you get a good blue Hoopsi. Wondering if those aren't from the best colored trees they are taking scions from. Cher

After looking at dozens of pictures online and reading as much as I can.... I agree it could have something to do with intake from the soil. Either salt retention, or inability to take up nutrients.... Most of my plants just don't fit the pictures or descriptions. Vericullum wilt is my only other suspect. Yellow leaves started at bottom, but are quickly working their way up on at least two of my four plants in the ground. (The potted plants look fine.) Now im also getting full wilt on extended stems....many that have small clusters of flowers....they just turn brown and get soft and die. I went to the nursery to buy fungicide but the guy told me not to bother. In our weather (San Fran) and this late in the game, it wouldn't do much. Just to wait and hope some hot sun comes and gives some new growth and life. He also recommended (usually a no-no) to give a little nitrogen (i mentioned fish emulsion) to see if some new leaf growth can overcome the disease. suggestions? ideas? thoughts?
