Frequently Asked Questions
Q: Can Sapphire grapes be grown in Kerala?
Grapes generally prefer drier climates. In Kerala, growing is possible in drier inland areas but challenging in high-humidity coastal regions due to fungal disease pressure. Raised beds with excellent drainage and regular fungicide management are essential.
Q: How long before Sapphire grape vines produce fruit?
Expect first significant harvest in year 2–3. Young vines in year 1 should have flowers removed to direct energy into root and vine development.
Q: What is the best fertiliser for grapes?
Balanced NPK at planting; switch to potassium-rich fertiliser during fruit development for improved sweetness and colour.
