I started approximately 12 cuttings in November, first by sitting in water and once roots were a couple inches long, I planted into a potting soil mixture. It is now mid February and all plants doing well and now have a couple vines over a foot long! My question is, I believe I will not plant them until mid April, so should I prune back the growth on the plants that have really started to grow fast? I live in southern New Jersey.
Thankyou, I transplanted the plants today, the roots were more numerous than I had expected..
I would move each cutting into a 1 gallon nursery pot.
Plant them individually to avoid competition of the roots, water, space and nutrients.
They can stay comfortably in the pot until you can move them outdoors.
Add a small trellis to the pot to hold up the vines.
You do not need to prune the new growth.
Keep the soil moist, but not to wet.
Water cools the roots and to frequent of watering will slow root growth.
