Kolkata Gardener Turns Delivery Boxes Into Plant Protectors

Your online shopping boxes might be exactly what your garden needs to survive the summer heat.

Krishna Khuku, a home gardener in Kolkata, has turned cardboard recycling into a gardening solution. She shares three practical ways to protect plants using materials most people throw away.

Her first hack addresses India's scorching summers head-on. Placing cardboard around plants creates a protective barrier that locks moisture into the soil and prevents it from drying out. The cardboard also regulates soil temperature and blocks weeds from taking root.

"Using cardboard reduces evaporation from the top exposed soil, preventing it from drying out by holding the moisture in," Krishna explains. It also keeps pests away naturally.

Her second method uses cardboard as mulch. As the material breaks down, it releases nutrients directly into the soil. Krishna recommends choosing boxes that are 100 percent recyclable or compostable for the best results.

The third technique transforms cardboard into rich fertilizer. Krishna fills large grow bags with shredded cardboard for composting. Worms eat through the biodegradable material until it becomes nutrient-dense food for plants.

The Ripple Effect

India recovers between 2.4 and 4.3 million tonnes of cardboard annually, with 30 to 60 percent getting recycled. Krishna's methods offer households a direct way to participate in this circular economy while improving their gardens.

Her approach solves two problems at once. Gardeners get free materials to protect their plants from extreme weather, and families reduce the cardboard waste piling up in their homes.

Krishna also suggests using sturdy boxes as planters and softer ones as seedling starters. Every delivery becomes an opportunity instead of trash.

"Next time you get them, don't throw them away," she reminds fellow gardeners.

One woman's simple observation is helping home gardeners across India keep their plants thriving while giving cardboard boxes a second life.
