Grape Vine Decline in Pot: Overpotted, Insufficient Sun, Wrong Winter Care

Your repotted grape vine shows silver-gray leaf edges and stalled growth. Multiple issues:

1. Overpotted = Overwatering Risk

• Large pot + small root ball = swamp conditions
• Empty drain tray at 1 hour (turkey baster)
• Grapes are NOT swamp plants
• Better: individual pots per vine (prevents tangled nightmare)

2. Grapes Need FULL SUN All Day

• Silver-gray leaves = light starvation
• Indoor light never sufficient
• Move outdoors ASAP (nights >45°F, days >50°F)

3. Winter Dormancy Required

• You watered all winter = prevented dormancy
• Next winter: unheated garage/shed AFTER leaf drop
• No light needed when leafless
• Delays spring growth to match outdoor conditions

Immediate Actions

1. Empty tray religiously
2. Maximize light immediately
3. Move outdoors when temps allow
4. Don't expect much until outdoor transition

Grapes are outdoor plants. Pots are a compromise. Sun + dormancy + drainage = success.
