Position – In general, grapevines (including the sunred) love to bask in the sun for most, if not all of, the day. So, find a spot that gets at least 6 to 8 hours of sunshine a day. A little afternoon shade is fine. Vines grow on walls, trellises or pergolas; so support your sunred on a sturdy structure that will guide its growth.
Size – The sunred grapevine grows to 1.2 to 3 metres in height, with a similar spread. Plant your vine a good 2 to 3 metres away from the next one to allow it to spread and grow freely.
Soil Type – This is a hardy plant that can survive in most well-draining soil types. A neutral to slightly alkaline pH of between 5.0 and 7.2 is ideal. The soil needs to be well-draining so that it is loose enough for the roots to extend deep down, soaking up the water and nutrients.
Mulch – Use organic mulch to prevent too much water from evaporating from the soil. This also helps to keep weeds from overtaking the area around your vine. Organic material like grass cuttings, old leaves, straw or woodchips is fantastic.
Watering – Usually, not much watering is required for vines as they are tough, favour hot conditions, and get water from the soil. But, a soft, gentle watering once every two weeks will keep your plant healthy and thriving.
Fertilising – You will only need to feed your plant with fertiliser if your soil is really lacking, because they are designed to reach their roots deep into the ground to get enough of the nutrients they need. If you do need to fertilise your sunred, you could opt for aged manure or a standard all-round fertiliser. Apply it once a year in spring. Do not over-fertilise your vines.
Pruning – Prune your sunred vine in winter, when they are dormant, for even more grapes the next season. Cut it back hard, removing all branches that have had grapes or those that are older than two years.
Harvesting – Pick your sweet, juicy grapes when they taste ready. Usually, the sunred grape vine is ready to be harvested mid-season (around the middle of February).
