Hi! I have a newly plante... #185337

Asked May 26, 2014, 12:12 PM EDT

Hi! I have a newly planted Concord grape vine that isn't doing so well. It was ok for a few days, but the leaves started to turn yellow, some have purplish spots. It is planted in the ground, but has a bottomless pot surrounding the vine. There is only one vine at the moment, planted in an area that gets 5 ish hours of direct sun a day. Help?

Your grape vine looks stressed. For best growth and to produce fruit grapes require a full sun location in a well drained soil. They are best planted in the ground (not containers that may confine the root system). Grapes are deep rooted plants. The roots may dry out at the top of the potting mix especially if using a soilless mixture. 

Grapes can be susceptible to black rot, a fungal disease. You will have to monitor for this and usually requires a spray schedule (fungicide) for control.  We have general information on grapes that includes some pruning information. http://extension.umd.edu/growit/fruit-profiles/grape
You will have to look at other university sites for additional information http://www.virginiafruit.ento.vt.edu/VirginiaGrapeSite.html

If you have another location in full sun you should transplant your vine in the ground. Otherwise, the vine may grow but will never produce fruit consistently.

Hi. As my email said, the vine is planted in the ground. That is a broken pot with no bottom or back place for ornamental reasons. The vine gets the most sunlight available in the yard, 5 ish hits a day, from about 9:30am to 3:30 pm.

Grapes want to be in full sun, so if you can't move your grape it will always be weakened from lack of sun.  This makes is susceptible to diseases and pest insects (insects are actually attracted to weaker plants first.)  From the photo, we can't say exactly what is currently affecting your grape.You can spray with fungicides, etc. but your grape will not perform well for you, so we'd recommend that you move it if you possibly can and, if not, you might want to consider a small fruit that tolerates more shade--such as blueberries.
