A lemon tree by the doorstep is a familiar sight across Tamil Nadu and Puducherry, and for good reason: citrus plants are productive, fragrant when in flower, and well suited to our warm climate. Even without a garden, you can grow lemon, mosambi (sweet lime) or orange plants in large pots on a terrace or sunny balcony. With the northeast monsoon arriving this month, it is also a good time to plant, as long as you plan for drainage.
Why grow citrus in pots?
- Fits small spaces: a single large pot on a terrace can hold a fruiting citrus plant.
- Easy to move: you can shift the pot into the sun, or away from waterlogging during heavy rain.
- Better control: you choose the soil mix, so drainage is in your hands.
- Grafted and air-layered plants bear sooner than seed-grown ones and stay true to their variety.
Choosing the right plant
For most homes, a lemon is the easiest place to start. Varieties like our Thai Patti / Taiwan Lemon plant are popular for pots. If you prefer a sweeter fruit for juice, try a grafted Mosambi sweet lime plant. You can browse other citrus options, including Nagpur mandarin, table orange and pomelo, in our fruit plants collection.
Pick a big enough pot
Citrus roots dislike sitting in wet soil, so the pot matters as much as the plant.
- Start a young sapling in a 12 inch pot, then move up to a larger pot or grow bag as it grows.
- Make sure there are several drainage holes at the bottom.
- Plastic grower pots are light, durable in sun and rain, and easy to move. Our 12 inch brown pots (pack of 12) are a practical choice if you are planting several fruit plants.
Soil mix for potted citrus
Use a loose, well-draining mix. A simple home recipe is garden or red soil, well-rotted compost or vermicompost, and a little cocopeat or coarse sand to keep it open. Avoid heavy clay soil on its own, which stays wet for too long during the monsoon.
Sunlight and placement
Citrus plants need plenty of direct sun to flower and fruit well. Aim for at least 6 hours a day. An east- or south-facing terrace usually works well. Raise the pot slightly on bricks or a stand so water can drain freely from the bottom.
Watering through the monsoon
- Check the soil before watering: water only when the top couple of centimetres feel dry.
- During heavy rain spells, you may not need to water at all for days.
- Never leave the pot standing in a saucer of water.
- Yellowing leaves and leaf drop after a long wet spell often point to soggy roots, so improve drainage and let the soil dry a little.
Feeding
Potted plants use up nutrients faster than plants in the ground. Add a handful of compost or vermicompost every month or so during active growth, and use a balanced fertiliser as directed on its pack. Avoid heavy feeding right after transplanting; give the plant a couple of weeks to settle first.
Common problems to watch for
- Leaf curl and chewed new leaves: check young shoots for insects and caterpillars. Pick off caterpillars by hand and wash away small pests with a strong spray of water or a neem-based spray.
- Flower and fruit drop: some drop is normal on young plants. Keep watering steady rather than letting the pot swing between bone-dry and waterlogged.
- Suckers below the graft: on grafted plants, rub off any shoots growing from below the graft joint so they do not take over.
Repotting and pruning
When roots start circling the pot or coming out of the drainage holes, move the plant to a pot one size larger. Light pruning to remove dead, crossing or weak branches keeps the plant compact and lets light into the centre.
