Rained somewhat the morning of 7/1.  Did not water evening 7/1.  Temp reached mid 90s 7/2 (today).  The tomatoes did not show wilt at 3pm.  I expected some wilt.  This could mean the containers are retaining more water this year.  Mushroom compost does impede drainage and was added this year to most containers.  I have to water everything this evening.
