Requirement at the Time of Plantation

How to Take Care
Sunlight Requirement: Ensure the vines receive full sun to maximize fruit production and sweetness.
Fertilizer: Apply a balanced fertilizer in early spring to encourage healthy growth, and again in midsummer to support fruit development. Be careful not to over-fertilize, as this can lead to excessive leaf growth at the expense of fruit. For more on fertilizers, see our guide on NPK fertilizers for plants.
Water Requirement: Regular watering is essential during the growing season to keep the soil consistently moist. However, avoid waterlogging, as it can harm the roots. Learn about the slow drip watering system for your pots garden to maintain efficient irrigation.
Mulching: Use organic mulch like straw or wood chips around the base of the vines to retain moisture, suppress weeds, and maintain even soil temperature. Explore our article on mulching for more techniques.
Companion Planting: Plant alongside marigolds and garlic, which are known to deter pests naturally, enhancing the health and productivity of the vineyard. Discover additional companion planting strategies to boost your garden’s biodiversity.
