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?

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.

What are their fertilizer and water requirements? Will they be useful as a bit of a wind- and soundbreak? Thank you.
