|
|
I LIVE IN THE NORTHERN TX PANHANDLE. WE "CAN" GROW SHUMMARD OAKS.
IT'S SEPTEMBER 1 AND SEVERAL OF MY SMALL, UNDER 10 FT. SHUMMARD OAKS ARE TURNING YELLOW. SOME LIGHT GREEN TO YELLOW. I SOAKED THE OAKS TWO WEEKS AGO AND THE GROUND BELOW IS NOW CRACKING. THE LEAFS APPEAR TO HAVE BROWN AREAS AND SPOTS. COULD IT BE OAK LEAF SPOT, THEY TURNED IN A HURRY IT SEEMS. I HAVE WATERED TODAY.
HELP, JOE |

Since no one else has replied, I'll throw this in. Like you said, it is September. Down here in Central TX we've had rather unusual weather. Could it be just the time of year?

How were these trees planted? Do you know? Can you see the root flare? As a rule, established trees do not need to be soaked, ever. Overwatering, I am told, is more of a problem than not enough water.
I know it is frustrating, but please do not shout. :wink: |

| Sounds like a deficiency. I have seen several around town with this problem. I believe you should apply Ironite and the sick tree treatment, check on the site, there is plenty of info here!!! I have a small (6 ft. tall) Shumard red oak and it's leaves just started turning red. Make sure you don't overwater!!! Oh, and don't hammer nails into the trunk (old timers thought this would cure iron deficiency, it usually just makes a nasty scar). Good luck!!!!!! |

Ironite contains arsenic. :( It is better to add iron using Texas greensand. :) It is a product approved by TORC. :wink: http://www.dirtdoctor.com/org_research.php |
