How to Keep Your Plants Healthy During the Monsoon Season: Tips Every Gardener Should Know
The Indian monsoon brings heavy rains, high humidity, and often less sunlight – conditions that can both nourish and challenge your plants. Ample rain can spur rapid growth, but it also raises the risk of waterlogging, fungal diseases and pest infestations. To ensure a lush garden, gardeners must adjust their care routine during this rainy season. This guide covers practical indoor and outdoor tips – from drainage and watering to pruning and pest control – with common plants like tulsi, hibiscus and money plant in mind.
Monsoon rains can temporarily wash away nutrients and create a humid environment where mold thrives. Without proper precautions, even sturdy plants may suffer root rot or disease. On the upside, rainwater is often purer and cooler, giving your plants a natural boost if managed well. By improving soil drainage, trimming excess foliage, and watching for pests, you can help your plants not just survive but thrive in the rainy season.
Indoor Plant Care in Monsoon
Indoor plants won’t be directly rained on, but high humidity and damp air can still affect them. Poorly ventilated rooms may trap moisture, inviting mold or mildew. Follow these tips to keep your houseplants healthy:
Use well-draining soil and pots:
Mix sand, perlite or cocopeat into potting soil so water doesn’t pool around roots. Ensure every pot has drainage holes at the bottom. Elevate pots on stands or bricks so excess water can escape from the saucer. For example, holy basil (tulsi) – a popular indoor/outdoor herb – grows best in loamy, well-draining soil and a pot with good drainage. Remove any thick mulch during monsoon to avoid water stagnation.
Water sparingly:
The air and soil hold more moisture in the monsoon, so do not overwater. Check the top inch of soil with your finger: if it’s still moist, skip watering. Money plant (pothos), for example, only needs water when the topsoil feels dry. Overwatering is a common mistake; it leads to root rot in succulents, pothos, and many indoor plants.
Ensure bright light or airflow:
Monsoon clouds can reduce sunlight. Place plants near east- or north-facing windows for bright, indirect light. You may even use grow lights on dark days. At the same time, open windows or use fans briefly to improve air circulation. High humidity indoors can encourage mildew, so even a short period of ventilation helps leaves dry and stay healthy.
Monitor and control pests:
Watch for common indoor pests like aphids, mealybugs or fungus gnats. High humidity can attract insects. Inspect leaves and stems weekly. If you spot pests, wipe leaves with a neem-oil or mild soap solution. Neem oil is an organic remedy that works on many bugs without harming indoor-use safety. Keep plants dust-free (wiping foliage after rainstorms) so infestations don’t hide under leaves.
Adjust pot positioning:
If you have potted plants on balconies or near windows, protect them from getting drenched by heavy downpours. Move delicate plants (like ferns or orchids) under eaves or inside until the rain subsides. Conversely, when the sun peeks out between showers, move plants back to sunlit spots to boost photosynthesis.
By following these indoor tips, even tender plants like money plant or snake plant can stay healthy during the humid months. For instance, a money plant thrives in bright indirect light and a peat-based mix, and should only be watered when its soil dries out. Tulsi grown indoors will appreciate this care too: ensure good drainage and give it some outdoor sunshine on dry days.
Outdoor Plant Care in Monsoon
Outdoor gardens and balcony plants get drenched by monsoon rains and must withstand wind and pests. Use these guidelines to safeguard your plants:
Improve soil drainage:
Heavy rains can saturate soil, suffocating roots. Make raised beds or mounds so water runs off. Mix organic matter (compost, cocopeat, sand) into garden soil to improve its structure and drainage. For potted outdoor plants, fill pots completely with a mix of garden soil, manure, and compost. This blend holds nutrients without flooding the top layer.
Prune and clean up:
Trim back overgrown or dead branches before and during the rains. Pruning helps sunlight and air reach all parts of the plant, keeping foliage dry and reducing fungal risk. Cut away any fallen or yellow leaves from the soil to prevent disease spread. For flowering shrubs like hibiscus and jasmine, remove spent blooms to divert energy to new growth. Proper pruning also prevents broken limbs – a heavy downpour can snap wet, weighty branches, so support tall plants with stakes.
Provide shelter for fragile plants:
Some plants dislike beating rain. Move delicate potted plants (seedlings, begonias, young herbs) under a porch or patio cover when storms hit. You can also use umbrellas or garden fabric to shield sensitive leaves. However, remember to return plants to natural light when rain pauses.
Watering schedule:
Outdoor plants often don’t need extra watering during monsoon. In fact, skip your usual watering routine if it’s been raining. Allow rainwater to soak in first. If there are long dry spells between rains, give water in the morning so plants can dry out before night. After an unusually heavy deluge, check if soil is still moist before watering again.
Pest control:
Warm, damp weather favors pests like snails, slugs, mealybugs and certain insects【13†L91-97】. Regularly check underside of leaves and stems for eggs or chew marks. Remove snails by hand or use barriers. If pests appear, apply organic treatments: spray neem oil or garlic-chili solution on affected plants. Companion planting also helps – herbs like basil (Tulsi) and marigolds can repel pests naturally.
Fertilizing:
Monsoon can leach nutrients from soil. Once heavy rains subside, consider a light feeding with a balanced fertilizer to replenish lost nutrients. However, do not apply fertilizer just before or during heavy rain as it will wash away. A gentle dose after rain showers is best.
Many plants actually love the rainy season. For example, hibiscus, marigold and jasmine produce vibrant blooms during monsoon. On the other hand, plants like Tulsi (holy basil) thrive best if their soil doesn’t stay soggy. By staking tall plants (e.g. tomatoes or lanky hibiscus) and spacing plants with enough air gap, you help them withstand wind and dry faster after the rain.
