The rainy season is good for plant growth, but potted plants need some extra care at this time. Excess rainwater, soil that stays wet for long periods, too little sunlight and fungal infection can ruin even healthy plants. Follow a few simple rules, though, and your potted plants will stay green, fresh and lively all through the monsoon.

Standing water is the biggest enemy of potted plants in the monsoon. If the drainage hole at the bottom of the pot is blocked, excess water cannot drain away, the roots run short of oxygen and the risk of root rot rises. Check the holes regularly and, if needed, put the pot on a stand so water can drain easily.

Many people water their plants every day out of habit, even in the rains. But in the monsoon the soil stays wet for a long time, so test the moisture with a finger before watering, and water only when the top few centimetres of soil have dried.

In spells of heavy rain, move potted plants to a veranda, shed or other spot with light and air but out of the direct downpour. This protects them from too much water.

Soil that stays wet for long can become compacted, so the roots do not get enough air. Very carefully loosen the top layer a little; this improves air circulation and growth.

Humidity helps fungal diseases spread quickly in the monsoon. Remove yellow, dark-spotted or rotting leaves and dried branches promptly to reduce the risk of disease spreading to other parts.

Even when there is little sun on rainy days, keep plants where enough natural light and air reach them. Leaving some space between plants rather than crowding them helps air move and reduces fungal infection.

Chemical fertiliser applied in heavy rain can be washed away or damage the roots. In the monsoon, a moderate amount of organic fertiliser or compost feeds the plant slowly and keeps it healthy.

Snails, slugs, mealybugs, aphids and other pests can attack more in the rains, so check the leaves, stems and soil carefully at least once or twice a week. Acting quickly when a problem appears makes it easy to save the plant.

Weeds growing in the pot share the plant's nutrients and water, and can also shelter pests and pathogens, so clear them regularly.

Dry leaves, rotting flowers or dirt piled around the pot can breed fungi and bacteria. Keep pots and their surroundings clean; a clean environment helps keep plants free of disease.

Keeping potted plants healthy in the monsoon does not take much work, only regular observation and proper care. By not letting water collect, watering only as needed, ensuring enough light and air and dealing quickly with disease and pests, you can keep them healthy with ease. With a little care, your veranda or rooftop garden will stay green, fresh and charming throughout the rains.
