Have already talked with the county extension office and they have proven to not know what they are talking about so I thought I would give my fellow plantoholics a shot. I have two Sawtooth Oaks that are planted on a slight slope in VERY good soil. They have been in the ground for 7 years or so and have grown extremely well. This year they have not filled out as usual and are very sparsely leaved. They are also producing leaves that are very stunted, yellow and cupped. I have a feeling that they are lacking micronutrients and are not able to take them up due to high PH. (The soil test is not back from the lab yet)
My question is- have any of you been successful in raising your PH to a degree that is sustainable, both over time and financially? I have read about different ways to achieve iron uptake, but would like to know if anyone has personal experience.
Side note- The leaves show no signs of lesions or insect damage, just to let you know.
I would like to save these two but only if it would be something that wouldn't put me in the poor-house, and hopefully would last at least a couple of years. Thanks in advance.
