Hi guys, I work at a New England Golf and Tennis resort and I maintain five clay courts (Har-Tru). We roll them frequently, sweep them after every match/hitting session. We water them mid-day. It seems like we do everything right and the people like the courts a lot..... buuuuttt when I play it seems like they are too soft for me, especially behind the baseline. I seem to chew up the court soo much. sometimes you just can't slide, instead, my foot just digs deep into the clay causing a nasty looking hole with clay all around it. It really is gross!!! What are some of the causes of this, and is there any way to fix it. I have a feeling the Clay may be a little old... How long until you should replace all the har-tru? Are there any other remidies for soft clay courts. We also put calcium on them regularly. Thanks for the help.
