Vadukapuli (Citrus medica)

A traditional, heritage citrus cultivar deeply rooted in Kerala culinary culture, famous for producing massive, thick-rinded, bumpy, globe-to-oblong yellow fruits valued for their highly acidic juice, fragrant aromatic essential oils, and thick inner albedo pith essential for preparing iconic Sadya pickles (Vadukapuli Achar).

Grafted and air-layered plants adapt exceptionally well to container gardening and terrace setups when grown on dwarfing rootstocks, maintaining a compact, manageable canopy with minimal pruning and fruiting heavily within just 1 to 2 years!

Description

Vadukapuli Lemon is a traditional citrus fruit commonly used in Kerala cuisine, especially for pickles and curries. It grows best in full sunlight, receiving around 6–8 hours of direct sunlight daily, and thrives in warm, humid tropical climates. Plant it in fertile, well-drained soil enriched with organic matter. Water regularly during the early growth stage and dry periods, but avoid waterlogging. Prune dead or overcrowded branches to improve airflow and maintain a healthy shape. With proper care, the tree can produce large, aromatic fruits with a thick rind.

Recommended Planting Method for Best Results

For healthy growth and strong establishment, prepare a 2–3 ft deep pit. If available, place a layer of green leaves at the bottom. Mix 1.5 kg bone meal, 1 kg oil cake, 20 kg raw cow or goat dung, and 100 g urea with an equal quantity of soil, then fill the pit and cover it with soil.

Leave the pit for about one month, watering it daily so the mixture decomposes well. After one month, mix the contents again and add 100 g calcium or dolomite. Wait one more week, then plant the sapling.

If you need to plant immediately and cannot wait for the one-month decomposition period, do not add oil cake or calcium/dolomite; use only the soil, manure, bone meal, and urea mixture for planting.
