The long range summer forecast frot the great lakes is that it will not get hot. The past week (and upcoming week) have been beautiful for humans (mid-high 70s, loads of sun and low humidity) but cool for tropical palms. I have two coconuts, two small bottle palms, musa basjoo bananas, two sabal palmettos, 3 sabal minors, 1 butia capita, and two mexican blue palms. They are all growing but much slower than they would in a warmer summer. Will a little extra fertiliaing help or hurt. I know enough not to over fertilize but I'm wondering if a little extra will speed up growth some. It's dropping into the mid 50s here at night.
