Re: New Grape plants and brown leaves
Are you in clay soil? I suspect over watering. I have areas of clay/rock "soil" and I water about 25 gallons per plant over 24 hours at 1 gph once a week. On new plants, I water every 3-4 days about 12 gallons over 12 hours (drip irrigation). I check those plants every couple of days by digging about a foot away from the plant to a full shovel depth, but they rarely need more. A related problem in clay soil is an amended planting hole acting like a pot with no drain.
