Vitis belaii

• Grape

Seed - best sown in a cold frame as soon as it is ripe[K]. Six weeks cold stratification improves the germination rate, and so stored seed is best sown in a cold frame as soon as it is obtained. Germination should take place in the first spring, but sometimes takes another 12 months. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in a cold frame for their first winter. Plant out in early summer.

Cuttings of mature wood of the current seasons growth, December/January in a frame. These cuttings can be of wood 15 - 30cm long or they can be of short sections of the stem about 5cm long with just one bud at the top of the section. In this case a thin, narrow strip of the bark about 3cm long is removed from the bottom half of the side of the stem. This will encourage callusing and the formation of roots. Due to the size of these cuttings they need to be kept in a more protected environment than the longer cuttings.

Layering.

Prefers a deep rich moist well-drained moderately fertile loam^[2][3]. Grows best in a calcareous soil^[3]. Succeeds in sun or partial shade though a warm sunny position is required for the fruit to ripen^[3].

The young growth in spring can be damaged by late frosts. Plants climb by means of tendrils^[4]. Any pruning should be carried out in winter when the plants are dormant otherwise they bleed profusely^[4][3]. Plants growing at Kew bear a good crop in most years. The fruits and the bunches are quite small but the flavour is good but the fruit is very seedy[K]. Plants in this genus are notably susceptible to honey fungus^[3].

This is probably a cultivar, we need to research further.
