Position – Plant your red globe grapevine in a spot that gets full sun or only a little afternoon shade. It does well in dry, hot conditions; especially when the fruits are ripening.
Size – The red globe vine grows well in pots or the ground and reaches a height of between 2 and 3 metres when mature.
Soil Type – A well-draining sandy soil is best for your red globe grapevine as it allows the roots to grow downwards freely without retaining excess water. A neutral to slightly alkaline soil pH (5.5 to 7) is recommended.
Mulch – Apply generous amounts of mulch around the base of your vine (a few centimetres away from the actual stem) so that water can’t evaporate from the ground too quickly. Mulch also helps to keep weeds away. Use organic materials like old leaves, grass clippings, woodchips, and so on.
Watering – In the drier months, water your vine slowly and gently once every two weeks. When there have been rains, you may be able to skip the watering.
Fertilising – When your vine is over a year old, you can start to feed it lightly, if necessary. However, if your soil is in good condition, it will likely not need extra fertilisation.
Pruning – Prune your red globe hard every winter. You can remove up to 90% of the previous year’s growth, cutting back all the vines except for the strong, well-established ones once the plant is mature. Leave only a few buds on each arm, and remove all flower clusters as soon as they emerge.
Harvesting – These scrumptious grapes can be harvested when they are sweet enough. The longer they’re left to ripen in the sun, the sweeter they will become. So, be patient and allow them to stay on the vine for 2 or 3 weeks after they first look ready.
