1. Rethink Your Watering Routine
The biggest mistake plant parents make during the monsoon is sticking to their summer watering schedule. With high humidity in the air and less direct sunlight, the soil in your pots will stay moist for much longer. Overwatering is the fastest way to kill
a plant, leading to root rot, a condition from which few plants recover. Instead of watering on a fixed schedule, get into the habit of checking the soil first. The classic ‘finger test’ is your best friend: insert your finger about an inch into the topsoil. If it feels dry, it’s time to water. If it feels damp or moist, wait another day or two and check again. For most indoor plants, this might mean watering once a week instead of every few days.
2. Ensure Excellent Drainage
Proper drainage is non-negotiable during the monsoon. Waterlogged soil suffocates the roots, preventing them from absorbing oxygen and nutrients. Start by checking the drainage holes at the bottom of your pots. Are they clear, or are they clogged with soil? If you have plants on trays or decorative outer pots, make sure to empty any collected water immediately after watering. Never let your pots sit in a puddle. A great trick is to use 'pot feet' or simply place a few pebbles or bottle caps under your pots to elevate them slightly, allowing air to circulate underneath and water to drain freely. If you plan on repotting, consider adding materials like perlite, coco chips, or coarse sand to your potting mix to make it lighter and more porous.
3. Prune for Better Airflow
A lush, overgrown plant might look beautiful, but dense foliage can be a problem in the humid monsoon weather. It traps moisture and reduces air circulation, creating the perfect breeding ground for fungal diseases like powdery mildew and black spot. Strategic pruning is key. Trim away any yellowing or dead leaves, as well as any branches that are crowding the centre of the plant. This will open up the plant, allowing air to move freely through the leaves and helping them dry faster after a humid night. This not only prevents disease but also encourages the plant to grow bushier and healthier once the sunny days return.
4. Go on Pest and Fungus Patrol
The damp, cool environment of the monsoon is an open invitation for pests. Slugs and snails will be on the move, especially in outdoor gardens and balconies. Mealybugs and aphids also thrive in these conditions. Make it a habit to inspect your plants regularly, paying close attention to the undersides of leaves and the joints where leaves meet the stem. If you spot pests, act quickly. For fungal issues, ensure good airflow and consider a preventive spray. A simple solution of neem oil mixed with water and a drop of liquid soap makes for an effective organic pesticide and fungicide. Spray it every 10-15 days to keep unwelcome visitors at bay.
5. Chase the Sunlight
One of the biggest challenges during the monsoon is the lack of bright, consistent sunlight. Most plants, even those that prefer indirect light, will struggle with weeks of overcast skies. Observe how the light moves in your home during this season. You may need to temporarily relocate your plants to a brighter spot, such as an east-facing window that gets the gentle morning sun or a covered balcony that is brighter than an indoor room. Remember to rotate your pots every few days so that all sides of the plant get some light. This will prevent them from becoming 'leggy' or stretching unevenly towards the only available light source.
6. Go Easy on the Fertiliser
Plants primarily use fertiliser when they are in an active growth phase, which is typically fuelled by ample sunlight. Since growth naturally slows down for many plants during the cloudy monsoon months, their need for nutrients also decreases. Continuing to fertilise at the same rate as you did in spring and summer can lead to a buildup of salts in the soil, which can burn the roots. It’s best to reduce the frequency of fertilising by at least half. If you normally feed your plants every two weeks, switch to once a month. Opt for a balanced, diluted liquid fertiliser over strong granular ones during this time.
