Bougainvillea dark green leaf veins
« on: October 16, 2013, 09:54 PM »
I have a bougainvillea that I acquired last spring.  It was not very healthy and I repotted it and pruned back sone of the branches to two leaf pairs.  The good news is that I wa rewarded with lots of new growth during the summer.  As I now bring it in to the house for the winter, I am noticing dark green leaf veins as seen in the photo.

My question is whether this is a sign of iron deficiency.  I had been fertilizing every 2 weeks with Peter's 20-20-20 at full strength and it does contain chelated iron.  Any opinions?

It might be iron but it might be that it was getting too much water. I'm just guessing so don't take my word for it

Seems more yellowing of the rest not darkening of veins. Sounds like transitional leaf drop.

It's a change in light and humidity.  Those leaves will drop, new ones will emerge.  This is why I defoliate my boug twice per year.  Once when it comes indoors, and again when it goes outdoors

Iron deficiency is marked by pale veins and green margins...opposite of what you're describing.  Could be iron or magnesium.  Hit with some micronutrients and you should have the bases covered.

Normally this is a sign that you have too much lime in the water and the PH of the water is high. Bougie likes acid conditions and gets this yellowing when the PH of the soil or water is high.
I normally add some acid in the water to bring the PH down.
High PH is also associated with lots of salts in the water...so You will need to be flushing your soil to prevent salt accumulation.
Chlorosis is a condition in which plants can not process/ take iron from the soil due to the high PH.
