Yellowing stem on blueberries.....
« on: June 12, 2019, 02:56:09 PM »
Having more problems with my blueberries.. we got hit with a heat wave this week over 100 degrees..Not sure if thats what caused this or something else?
Some of the leaves look like they were dried and crusted..and the base of the stem is yellow and looks unhealthy... Is this some sort of fungal infection?
thanks for the help

I think it's drought stress. Mine have been showing similar symptoms if I go two days between watering in this heat.

Really hard to tell - more pics of the leaves might help.
But it could be overwatering even from those pics. Since you have in a pot itís always a risk.
Drooping or wilted leaves can actually be a sign of overwatering. The brown at the base gives me the reaction of something rotting, not drying out.
Is the potting mix soaking wet if you poke your finger in the drainage hole(s)?

I should add that Iím not in Southern California and I donít  grow blueberries, so take what I say with a grain of salt.
I do stand by my generalized comments  ;D

Looks like Pythophora ( root rot) but you plant has healed itself .Over watering causes this in heavy soil.Add somme mulch to keep the humidity constant and to water less.The plant looks good and it will heal on its own.
