Trust Brings the Harvest — The Agronomy Behind Nantou Lychee

Q: When should lychee be fertilised?

Lychee has four key feeding points: a base feed before bud break to build roots and vigour, a calcium top-dressing at the young-fruit stage, potassium during fruit swelling for colour and sweetness, and a recovery feed after harvest. The young-fruit calcium feed is the most critical for firming fruit and preventing drop.

Q: Why do lychee fruits drop, and how can it be reduced?

Lychee fruit drop is usually caused by calcium deficiency at the young-fruit stage, unstable tree vigour, or nutrient competition. Top-dress calcium from post-flowering to fruit-set to strengthen cell walls and steady the tree, with a base feed (HeTiSu H.T.) to build roots — this markedly reduces physiological drop.

Q: What fertiliser firms up lychee fruit?

Use calcium at the young-fruit stage to strengthen fruit structure and prevent cracking, and potassium during swelling to boost colour and sugar, together with a base feed for roots — giving fuller, redder fruit. This case pairs a HeTiSu H.T. base feed with calcium top-dressing at fruit-set.

Behind Nantou’s lychee harvest is a season of trust-based agronomic companionship. He-Ti-Su base fertilizer builds the foundation and Zhen-Gai-Yong top-dressing supplies calcium for plump fruit — care from root to fruit for a full, ruby-red harvest.
