AusBonsai

Anyone have any idea of what is going on here?

Currently a good many of the leaves on my bougainvillea (in training) are looking like this.

Some sort of nutrient deficiency, potassium maybe.

iron deficiency i'd say...use good old epsom salts or change fert with higher Mg

OK thanks for the suggestions, I have fertilised regularly with Dynamic Lifter and supplemented with a couple of doses of Thrive. So I would have thought it would not have been deficient in nutrients.

Then again the growth on this tree has been prolific this year, so perhaps it is consuming everything I am giving it?

cheers,
Jeff

Hello Jeff,

I would check the soil Ph, i believe Dynamic Lifter raises the soil Ph.
The macro and micro nutrients from the Thrive may be out of reach to the plant with a high (or low) Ph.

Just a thought.

Good luck,
Kevin

dynamic lifter is ph neutral...containing N P K...not a complete fert...good for roots and flowers...but looks like your bougainvillea leaves are telling you they need Fe/Mg...but I'm sure Shibui, Watto, Treeman, Steven, KCpool, Wal etc are sure to chime in with the correct info I'm on my 3rd which are long necks

Max

How often are you feeding?
I feed mine weekly with powerfeed , plus slow release with trace elements

Dynamic lifter is definitely alkaline.

Chlorosis causes yellowing on new or mature plant growth, usually due to a deficiency in iron or magnesium. Chlorosis can also be a secondary problem related to root rot so check how wet it is. It can be controlled by increasing soil acidity with iron sulfate or aluminum sulfate. Follow instructions about dosage. Another treatment apply 1 to 2 teaspoons of Epsom salts diluted in 4 litres of water.

i thought dynamic lifter had ph 6.5

I presently cannot find an MSDS for Dynamic Lifter but below is a Technical Data Sheet:

Kevin...hahaha i was just about to post that ....i suppose continual use will lean towards alkaline

From what i have read on AusBonsai many times is Dynamic Lifter can cause considerable more damage to your potting medium than can be beneficial.
Besides raising Ph it also contributes to root rotting due to how it turns into a sludge over time.
I agree that it's a great product but as mentioned many times here on AusBonsai makes me very apprehensive in using it for Bonsai.

DL certainly raises PH, make sure you never put it on acid loving plants like Azaleas.

Bouganvilliea's like acid too.
