Hibiscus
A quintessential Indian garden favourite, the hibiscus is a hardy plant that thrives during the monsoon. Its large, vibrant flowers in shades of red, pink, and yellow add a wonderful splash of colour to the greyest of rainy days. Hibiscus loves moisture
but requires well-draining soil to prevent root rot, a common issue during the monsoon. A large pot with a good mix of soil, compost, and sand is ideal. While it enjoys the rain, ensure your pots have drainage holes to let excess water escape. Its sturdy, woody stems also help it withstand the blustery winds common on rooftops. Regular pruning in the early monsoon can encourage more blooms.
Balsam (Impatiens Balsamina)
Often called the “monsoon flower,” balsam is an easy-to-grow annual that puts on a spectacular show during the rainy season. It produces beautiful flowers in a variety of colours, including pink, purple, red, and white. These plants love the high humidity and consistent moisture that the monsoon provides. They are relatively compact, making them perfect for pots and containers on a rooftop. Sow the seeds directly into your pots at the beginning of the season, and they will germinate quickly in the damp soil. While they love water, good drainage is still crucial to avoid waterlogging.
Gourds and Beans
If you want to grow your own food, the monsoon is the perfect time for climbers like bottle gourd (lauki), ridge gourd (tori), and various types of beans. These vines grow vigorously in the warm, humid weather. The key for a rooftop setup is providing a strong trellis for them to climb. This not only supports the plant but also protects it from strong winds and keeps the fruit off the wet ground, preventing rot. Plant them in large bags or deep containers to accommodate their root systems. The natural rainfall often takes care of their water needs, making them a low-maintenance choice for a productive rooftop kitchen garden.
Turmeric and Ginger
Spices like turmeric (haldi) and ginger (adrak) are surprisingly well-suited for container gardening on a monsoon rooftop. These plants are grown from rhizomes and love the warm, humid, and wet conditions of the Indian rainy season. They have beautiful, lush green leaves that add a tropical feel to your garden. Plant the rhizomes in wide, shallow pots with rich, loamy soil. The monsoon rains provide the perfect amount of moisture for them to sprout and grow. Ensure the pots have excellent drainage, as stagnant water can cause the rhizomes to rot. You can enjoy a fresh, organic harvest right from your rooftop at the end of the season.
Herbs like Mint and Lemongrass
No garden is complete without fresh herbs. Mint (pudina) and lemongrass are particularly robust during the monsoon. Mint is famously easy to grow and spreads quickly, so it's best to keep it in its own pot to prevent it from taking over. It thrives in moist soil. Lemongrass also loves water and its grassy, flexible leaves handle wind well. Both herbs are perfect for adding fresh flavour to monsoon teas and meals. Coriander (dhania) is another great choice that grows quickly in the cooler, damp weather of the rainy season.
Essential Monsoon Rooftop Care
Beyond choosing the right plants, a few care tips are essential. First, drainage is non-negotiable. Ensure every pot has holes and elevate them on bricks or stands to prevent them from sitting in puddles. Second, be vigilant about pests and fungal diseases, which thrive in high humidity. Good air circulation between pots can help, as can a preventive spray of diluted neem oil every couple of weeks. Finally, provide support for taller plants or those with weak stems to protect them from strong monsoon winds. Grouping smaller pots together can also offer mutual protection.
