Haralson Apples that are organic that look great on the outside, but have some spots on the flesh inside and when made into applesauce have thickened yellow blobs rather than becoming thin applesauce.

I need an expert in lawn care. Black algae has spread throughout the entire lawn whether in sun, shade, wet or dry. It isn't slimy. It creates a thin patch like leather and kills whatever is under it.(Image 0963) It can't be raked because the rake slides right over it. I have sprayed it with "Wet and Forget" and it kills it leaving a white leather patch which again can't be raked. (Image 0965) It is killing the grass because it smothers it and when I pull up a patch of the algae there is bare soil. We have acidic soil with large white pines growing. Even with this extremely dry summer weather, it grew. Any humidity helps it thrive. We rarely water the lawn. We are on sand on Lake Michigan. We have a lot of moss in the grass and the algae seems to grow on it or near it. I don't know what else I can tell you but if you think of something let me know. Is there anything we can do to get rid of this? Thanks for your help.

A friend gave me some sweet potato plants this spring and I dug them up today. Are they edible?
