Hi,* I live in the San Francisco Bay Area inland.* I purchased three New Zealand* (The Gaurdsman) and planted them in my front yard.* The soil is sandy with full sun.* The flax were doing well but all of a sudden they have fallen flat to the ground.* I only water them once a week as the nursery told me.* The bottom of the stem feels a little soft.* I thought they have fallen flat because it has been so windy, but as I looked closer they just didn't look right.* The coloring hasn't really changed.* I haven't really noticed any new growth, but I could be wrong about that.* The stem at the base has a light brown, soggy look to them and feels kind of soft.* What do you recommend that I do?* Do you need*a picture?* Oh, I have purple fountain grass and Pink Guara planted with them and they are doing great.* I don't know what the problem is.* The tempature has been hot here.* In the 90's to 100's.
