[Monsoon Care Strategies (July--September)]
Ah, the monsoons — a season of relief for many after scorching summers, but it brings its own challenges of excess water, fungal issues, and luxuriant growth spurts. Indian monsoon conditions vary (some regions get relentless heavy rain, others intermittent showers with high humidity). Here's how to ride the wave of the rainy season:
Ensure Excellent Drainage: This is rule #1 in monsoon. Constant rain or overcast, high humidity means soil stays wet longer, risking root rot. Check all pots' drainage holes — clear any blockages (soil or roots that might clog them). If a decorative pot lacks drainage and is being carefully watered in dry times, now is the time to either drill a hole or move the plant to shelter. Use "pot feet" or bricks to slightly elevate outdoor pots so they don't sit in puddles (Manoj, 2022). If you have plates under pots outdoors, tilt them so they don't collect rain. For garden beds or lawns, ensure no low spots where water accumulates around plant root zones. Consider adding pebbles or coarse material at the base of pots if repotting, to improve percolation. Remember, monsoon rains can be unpredictably heavy — a pot that normally drains well could overflow if the rain is torrential. Having an inch of space below the pot's rim (not filled to the top with soil) acts as a buffer to hold some rain until it drains.
Trim and Prune at the start of monsoon: Monsoon often triggers a flush of new growth, and many plants bloom in this season (jasmine, rain lilies, herbs, etc.). It's good to do a cleanup pruning at the onset: remove dead or weak branches, trim excess leafy growth to allow air movement. This prevents fungal attacks by reducing dense canopies where moisture would sit (Manoj, 2022). Also, stake tall plants; wind and rain can topple or break them. For example, tie up climbers and provide support to any lanky seedlings shooting up. Monsoon is also the time to propagate — many cuttings root easily now due to humidity, so those pruned cuttings can become new plants.
Apply Preventive Fungicide and Pest Control: As per many experts, a prophylactic spray of fungicide early monsoon helps. Neem oil is a natural choice — spraying leaves and stems repels many fungal spores and insects (Manoj, 2022). You might do this every 10--15 days during continuous rain spells (Manoj, 2022). Ensure to spray the underside of leaves too. If a plant is prone to powdery mildew or black spot (common on roses, certain ornamentals in damp weather), consider a specific fungicide like a baking soda solution or commercial ones and use as directed preventively. Watch for pests: ironically, while rain can wash some away, others thrive — snails and slugs come out and may munch seedlings or soft leaves (set up beer traps or handpick and relocate them; copper tape around pots can deter slugs). Mosquitoes breed in stagnant water — empty any plant saucers or unused pots collecting water (not directly affecting plant health, but general safety!). Monsoon also brings out millipedes and earthworms in pots — worms are mostly beneficial (aerating soil), but millipedes can nibble roots if populations explode. Usually not a big issue, but if pot soil seems buggy, you can drench the soil with a mild neem solution. Mealybugs and aphids sometimes proliferate because heavy rain might not reach under leaves where they hide, and high humidity favours them — keep an eye out, use soap spray or neem if seen.
Controlled Watering (Yes, Still Water Your Indoor Plants!): A big mistake is to think monsoon = everything is getting watered. Indoor plants might get less light due to cloudy days, yet still not receive direct sunlight, so one might overestimate their moisture. Actually, you often water indoor plants less in the monsoon because ambient humidity keeps the soil moist longer. Always check the soil before watering; fungal root rot often hits in the monsoon due to overzealous watering on top of humid conditions. For outdoor potted plants, you may not need to water at all if rains are regular, but if there's a 3--4-day gap, check — the wind and occasional sun can still dry pots. So, water only as needed. Conversely, sheltered balcony plants might get no rain if the wind doesn't blow in, so don't forget them, thinking "it's rainy season"; they might be in a dry rain shadow and still rely on you.
Avoid Overfeeding: Generally, do not fertilise heavily during heavy rains. Nutrients may leach out quickly with overflow, and plants in low light won't uptake as fast. The exception is toward the end of monsoon, when many winter bloomers are preparing — a gentle feed then is okay. But during peak rains, focus on health over pushing growth. One could topdress with slow-release organic matter at the start of the monsoon so it gradually breaks down (rain helps compost release nutrients slowly). By mid-monsoon, plant roots might be more focused on staying oxygenated than grabbing fertiliser. If using chemical fertiliser, apply lightly and perhaps more frequently in small doses rather than one big dose that could wash away (fertiliser runoff is also an environmental issue in monsoons).
Sunlight and Repositioning: In extended rainy periods, light levels drop. Indoor plants near windows might not get their usual dose, so if any start looking etiolated (stretching, pale), move them to brighter positions or supplement with grow lights for a few hours. If safe to do so, occasionally rotate some houseplants outdoors during gentle rain for a "rain shower" — it can clean them and invigorate (rainwater has nitrogen and is soft, plants love it!). Just be mindful not to leave delicate potted ones out in a deluge that could flood the pot. For sensitive succulents or cacti, monsoon can be their peril — best to move them under shelter to keep them from rotting. Many succulents have a dormant period in monsoon due to less sun; keep them on the drier side.
Capitalising on Monsoon: This is the best time to repot and propagate. The abundant moisture and moderate temperatures mean reduced transplant shock. You can divide overcrowded houseplants, repot root-bound ones (fresh soil now will pay off in winter growth). Also sow seeds — many perennial seeds or vegetable seeds germinate well in warm, wet conditions. Monsoon is often considered India's planting season (for agriculture too) — things root faster, and establishment is good. So, if planning new additions or major landscaping for a client, monsoon can be a good window, provided you manage excess moisture. For example, want to lay a new lawn? Early monsoon rains will water it in nicely (but heavy rains can wash away seeds, so maybe mid or late monsoon). Want to start a new batch of holy basil or coleus cuttings? They'll root readily now.
Maintenance: Because plants grow vigorously now, a weekly trim/training session is useful. Pinch back fast growers to keep shape, direct vines (so they don't twine into places they shouldn't), and remove yellow leaves promptly (they'll rot and could spread fungus if left). Also, weed removal — weeds sprout everywhere with rains, pull them from pots/soil so they don't compete. Keep watch for any plant trays collecting too much wet fallen debris — clean them to avoid mould.
In essence, monsoon is a blessing of natural irrigation and a trigger for lush growth, but you must guard against the dark side: rot and fungi. The motto could be "keep it draining and keep it clean" for monsoon. If done right, you'll enjoy plants with rain-washed leaves gleaming, perhaps fragrant blooms (the smell of earth and jasmine in monsoon is heavenly), and new life burgeoning. Many plants will put on their best show now — water lilies bloom in monsoon, various gingers and tuberoses send out flowers, and foliage looks especially rich. Embrace that while mitigating the challenges.
