minor issue on new leaf flushes
« on: March 29, 2018, 02:02:09 PM »
All of my trees are flushing new leaves now.  I've noticed a few spots where the cluster of new leaves from a bud will shrivel up and fall off while still ~1cm in size.  This is only a tiny minority of new growth, maybe 1% on various trees.   Is this a normal thing?  Any idea why some leaves might be killed off so quickly? 

The only thing I can think of is perhaps these baby leaves are extraordinarily cold sensitive.   Prior to the spring growth flush I was keeping the minimum temperature in my greenhouse at ~33F.   Now with new growth and flowers I start the heaters when its ~36F, just to be careful.  It should not have dropped below 35F, which I thought was a safe temperature even for tender growth.

Could be the cold temperatures, but whatever the cause, I don't think it is any thing to worry about.
