The Ruby Roman grape plant is hardy and does well in most climates, but it is sensitive to cold weather, so it is important to plant these plants early in the year so that they have enough time to produce fruit before winter.
This particular type of grape needs plenty of sunlight and regular watering. It also needs decreased watering during the winter months when the plants go dormant.
It is important to fertilize them regularly with a low nitrogen fertilizer during the summer months because this will keep them producing fruit.
They should be planted in an area sheltered from potential frosts in late spring and get about 6 hours of sunlight daily.
How to Germinate
To germinate ruby roman grapes, they need a moist environment.
You can use a seed tray or a small pot with drainage holes in it. Fill it with soil and water it until the soil is damp but not soaking wet. Place the seeds on top of the soil and press them gently into it so that they are in contact with damp soil. Cover them with a thin layer of soil and keep them in a warm, dark place for at least two weeks.
