The leaves on my grape plants have turned yellow. The veins are still green but the rest of the leaf is yellow. I added some iron about a week ago and have not noticed any change as yet. Is there something else I need to do?
Rate This FAQ
I am assuming that your grape leaves that are yellowing have veins that are a darker green color than the surrounding tissue. This is iron chlorosis and the reason that your iron application did not work is 1)it may not have been chelated iron. Chelated iron works best in our soils 2)it was applied too late in the season. It should be applied in spring just as the leaf buds swell and are starting to open. When applied mid-summer,when all the leaves are full size, it does very little good. There are foliar sprays that work temporarily, but are not long lasting. They could be applied now. Next year, apply chelated iron in the spring at leaf bud swell. Also watch the watering. Overwatering causes chlorosis.

- Many of my potatoes this year have splits in them, but then the skins have grown over the splits, leaving a very uneven skin. Is there something I have done wrong? We have watered about every 4-5 days.
- I just bought a house and the yard is a mess. We have multiple varieties of grasses and weeds, dry spots, dead spots and rodent damage. I am a staunch do-it-yourselfer but the number of different problems to attack is overwhelming. Where is the best place to get educated or to get started? If I take a bunch of digital pictures of the various problems and plant types is there someplace I can take them to get good advice? Tru Green also came by and said we have grubs, but all they did was LOOK at the grass. I can pull up the dirt myself, but I don't know what to look for.
- I have a Blierana flowering plum tree that failed to leaf out fully this spring. I looked at it yesterday and found at least fifty places on the branches where a snake-like resin/sap has been pushed out of the branch. Is this a borer doing damage? What do I do? Should I remove the tree to prevent further damage to surrounding trees? Is there something I can spray? Can I ever plant a tree in this same spot? I have trees all along my fence line in a row and really need a replacement tree if this one is going to die.
- The grass in certain areas of my lawn is not growing well. I've been told it may be due to the fact that they're adjacent to pine trees, and that fallen pine needles have caused locally acidic conditions. It is suggested that I apply Gypsum in these areas. Are the diagnoses and suggestions plausible ?
- My purple crown locust has never bloomed in the 5 years that I've had it and the past two years in the summer whole branches of leaves are dying off. Should I remove it and start over?
- We have a scrub oak that has been growing between a pine and an aspen, which has made the oak very lop-sided. The aspen is gone now. How much purning can we do to the oak to try and even it's growth?
- I have a peach tree with lots of little branches that look burnt at the ends. The rest of the tree looks healthy, but the ends of the branches keep turning black and dying.
