Mistake 1: Sticking to a Summer Watering Schedule
The single biggest mistake plant owners make during the monsoon is overwatering. With high humidity in the air, the soil in your pots dries out much slower than it does in summer. Continuing to water on a fixed schedule can quickly lead to waterlogged
soil, which suffocates the roots because they can't get enough oxygen. This is the primary cause of root rot, often signalled by yellowing, mushy leaves and a musty smell from the pot. The solution is simple: ditch the schedule and check the soil. Insert your finger about an inch deep; if the soil feels damp, wait another day or two before watering. Your plants will need significantly less water during these wet months.
Mistake 2: Ignoring Poor Drainage
Good drainage becomes non-negotiable during the monsoon. Even if you're watering correctly, a pot without adequate drainage holes will trap water at the bottom, creating a swampy environment for the roots. This is a direct path to root rot. Many decorative pots lack holes, and even pots that have them can get blocked if they sit flat on the floor or in a saucer that is never emptied. Always use pots with drainage holes. If you use a decorative outer pot, make sure to empty any collected water from the saucer or tray after each watering. A simple but effective trick is to elevate your pots slightly using pot stands or bricks, allowing air to circulate underneath and water to escape freely.
Mistake 3: Underestimating Pests and Fungi
The warm, damp conditions of the monsoon are a paradise for pests and fungal diseases. High humidity encourages issues like powdery mildew (a white, dusty coating on leaves) and other fungal spots. Overly moist soil is also a breeding ground for fungus gnats, tiny flies whose larvae feed on your plant's roots. Mealybugs and aphids also become more active. To prevent this, ensure there is good air circulation around your plants. Avoid crowding them together and, if they're indoors, using a small fan on low for a few hours can help. Regularly inspect your plants, paying attention to the undersides of leaves. If you spot pests, a simple spray of diluted neem oil every 10-15 days can act as a great preventative measure. Wiping leaves with a damp cloth also helps remove dust and spores.
Mistake 4: Not Adjusting for Low Light
Weeks of overcast skies mean your indoor plants receive significantly less sunlight than they are used to. Light is essential for photosynthesis, the process plants use to create energy. Without enough of it, growth can become slow, weak, and 'leggy' as the plant stretches towards the nearest light source. Variegated plants may even start to lose their distinct patterns. To compensate, move your plants closer to windows, preferably those facing east or north to catch as much gentle light as possible. Rotate the pots weekly so all sides get some exposure. Wiping down your windows can also make a surprising difference in how much light gets through. For very dark homes, a simple LED grow light can be a game-changer.
Mistake 5: Fertilising Too Much or at the Wrong Time
Many plants naturally slow their growth during the low-light, high-humidity months of the monsoon. Because they aren't growing as actively, they don't require as many nutrients. Adding fertiliser as you would in the spring or summer can do more harm than good, potentially leading to 'fertiliser burn,' where excess salts build up in the soil and damage the roots. It is best to reduce feeding significantly or stop it altogether during the rainy season. If you feel your plant needs a boost, use a diluted, balanced liquid fertiliser no more than once a month. Focus instead on keeping the plant's environment clean by removing any yellow or dead leaves, which can otherwise decay and attract pests.
