1. Rethink Your Watering Schedule
This is the golden rule of monsoon plant care. With high humidity and frequent rains, the soil stays moist for much longer. Your regular summer watering routine will almost certainly lead to overwatering, the number one killer of household plants. Before
you even think about reaching for the watering can, do the 'finger test.' Stick your finger about an inch or two into the soil. If it feels damp, hold off. If it's dry, it’s time to water. For outdoor plants in containers, the rain might be doing all the work for you. For indoor plants, you might find you only need to water once a week or even less. Always err on the side of underwatering during this season.
2. Ensure Excellent Drainage
Overwatering is a problem, but stagnant water is a disaster. It leads to root rot, a fungal disease that quickly kills a plant from the roots up. The monsoon is the perfect time to audit your pots. Make sure every pot has at least one drainage hole at the bottom. If your plants are sitting in decorative cachepots without holes, get into the habit of removing the inner pot, watering it in a sink, and letting it drain completely before placing it back. For outdoor plants, consider placing pots on 'pot feet' or small bricks to lift them off the ground, allowing excess water to escape freely and preventing them from sitting in puddles.
3. Improve Air Circulation
Damp, stagnant air is a breeding ground for fungal and bacterial diseases, which manifest as white powdery mildew or black spots on leaves. To combat this, improve airflow around your plants. If you have a dense collection of indoor plants, space them out a little more than usual. This allows air to move between them, drying the foliage faster. You can even run a fan on a low setting for a few hours a day to keep the air moving. For balcony or garden plants, a bit of light pruning to thin out dense foliage can work wonders for improving circulation and letting light penetrate deeper into the plant.
4. Watch Out for Pests
Slugs, snails, mealybugs, and aphids love the damp, humid conditions of the monsoon. Be extra vigilant and inspect your plants regularly, especially the undersides of leaves and new growth. If you spot pests early, you can often manage them manually. A simple spray of neem oil solution (mix a few drops of neem oil and a drop of mild liquid soap in water) is an excellent organic preventative measure. Spray it on your plants every 10-15 days to keep most common pests at bay. For slugs and snails in the garden, natural deterrents like crushed eggshells around the base of plants can be effective.
5. Maximise Available Light
The monsoon sky is often overcast, meaning your plants are getting significantly less sunlight than they're used to. Sun-loving plants like succulents, bougainvillaea, and many flowering species might struggle. Move your indoor plants closer to windows, preferably south or west-facing ones, to catch as much light as possible. Remember to wipe down your windows to remove any grime that might be blocking light. It’s also a good idea to rotate your pots every few days so that all sides of the plant get some exposure to the light. Don't be alarmed if you see a little less growth during this period; it's a natural response to lower light levels.
6. Prune, Propagate, and Plant
While it may seem counterintuitive, the monsoon is an excellent time for growth. The high humidity acts like a natural greenhouse, making it the perfect season for pruning and propagation. Pruning encourages bushier growth and helps maintain a good shape. The cuttings you take can be easily propagated to create new plants! Species like money plant, monstera, snake plant, and coleus root very easily in water or soil during this time. It's also the best season to introduce new plants to your garden, as the ambient moisture helps them establish their root systems without the stress of intense heat.
7. Go Easy on the Fertiliser
Plants generally slow down their growth in the low-light conditions of the monsoon, so they don't need as many nutrients. Over-fertilising can lead to 'fertiliser burn,' which damages the roots. It's best to reduce the frequency and strength of your fertiliser. If you usually fertilise every two weeks, switch to once a month. Dilute your liquid fertiliser to half its recommended strength. Alternatively, you can switch to a slow-release organic fertiliser like vermicompost, which provides a gentle and steady supply of nutrients without the risk of burning the roots.
