After a few weeks of 90+ degrees & no rain, my white clover is starting to look a little stressed. There must have been some red clover mixed in here & there b/c I've got onesies & twosies that are growing & seem to be doing better than my White clover. Does Red clover handle droughts & heat better than white? I assume I can mix the 2 w/o any issues? If so, what types of MRC do you recommend?
