Yes, you can propagate grapes in winter! In fact, it's the ideal time to do it. Here's why and how:  

Why Winter is Best

• Dormancy: Grapevines are dormant in winter, meaning their energy is focused on root growth rather than foliage. This makes cuttings taken in winter more likely to root successfully.
• Easy to Identify: It's easier to select healthy, one-year-old canes for cuttings when the leaves have fallen.

How to Propagate Grapes in Winter

1. Gather Materials:

   • Sharp pruning shears or a knife
   • One-year-old grape canes (about pencil-thick)  
   • Rooting hormone (optional, but can improve success rates)  
   • Plastic bags or containers for storage
   • Well-draining potting mix or soil

2. Take Cuttings:

   • Choose healthy, disease-free canes from a grapevine you want to propagate.  
   • Cut the canes into 10-15 inch lengths, making sure each cutting has at least 3-4 buds.
   • Make a straight cut at the bottom of the cutting and a slanted cut at the top to help you remember which way is up.  

3. Treat Cuttings (Optional):

   • Dip the bottom end of each cutting in rooting hormone to encourage root growth.  

4. Store or Plant:

   • Storage: If you're not planting immediately, store the cuttings in a plastic bag with a moist paper towel in a cool, dark place like your refrigerator.
   • Planting: Plant the cuttings directly in the ground or in pots filled with well-draining potting mix. Bury the bottom two-thirds of the cutting, leaving 1-2 buds above the soil.

5. Care for Cuttings:

   • Keep the soil moist but not soggy.  
   • If you planted in pots, you can keep them in a cool, bright location until spring, when you can transplant them outdoors.
