Growing note
Needs a genuinely large pot, 16 inches or more, with sharp drainage, since the roots resent sitting wet. Hard Indian tap water tends to push the soil alkaline over time, which shows up as yellowing between the leaf veins (iron chlorosis); a dose of chelated iron or occasional rainwater helps. Slow to fruit, often 2-3 years from a nursery sapling. The leaves, stems, and unripe fruit contain citrus oils and psoralens that are toxic to cats and dogs, so keep pots out of reach.
Growing Lemon (Nimbu) in Indian apartments
Beyond the iron chlorosis already covered above, the most common actual pest problem on a potted lemon is citrus leaf miner, not root rot: silvery, squiggly trails tunneled through new leaves right after a flush of fresh growth, which curl and distort as a result. It's mostly cosmetic on an established plant and rarely worth spraying for, though badly affected new growth can be pinched off. Whether the tree fruits quickly comes down to how it started: a grafted nursery sapling, which is what most Indian nurseries actually sell despite rarely advertising it as such, fruits within 2-3 years, while a lemon grown from seed can take 5-7 years and often produces fruit that doesn't resemble the parent at all. Deep, infrequent watering suits a large potted or ground-planted lemon better than frequent shallow watering, since it encourages roots to grow down rather than staying shallow and heat-stressed near the surface. A layer of mulch over the root zone makes a real difference through Rajasthan-style summer heat, cutting how fast the pot or bed dries out and reducing the swings between bone-dry and soaked that stress the roots.
