Black Hamburgh Vines (also known as Frankenthaler) are very easy to grow and by far the best black grape for growing indoors because it will give a crop of sweet grapes that ripen in most summers, when other varieties would produce fruit that fails to ripen or develop any sweetness if there has been insufficient sunshine. The disadvantage is that this old variety is that it is susceptible to diseases such as botrytis and powdery mildew. The Black Hamburgh grape is suitable for an unheated greenhouse and will not be affected by frost. An early season grape but make sure it gets full sun & good feeding. Cut back to main framework in spring. Like other indoor grapes it is best planted in the ground, either in the greenhouse or outside the greenhouse with the main trunk trained to grow inside. If you have to grow it in a pot use the largest pot available and plant in John Innes Compost
Supplied in a 3 litre deep pot, young grafted plants with a main stem about the thickness of a pencil Height approx. 90cm. Shipped within 3 days
