Why?
1. Rainwater is magical:
Rainwater itself is a natural fertilizer – it contains nitrogen and many minerals that are beneficial for both soil and plants.
2. Soil microbes become active:
During this season, the microbial activity in the soil also increases, making the soil richer in organic matter.

That’s why, you often see weeds, small seedlings and even plants you never planted start growing on their own in your garden and pots during monsoon season.

Things to Know Before Fertilizing in Monsoon
In container gardening, the soil remains wet for a longer period during rain. There is less space for the soil in pots or containers, so it takes time to dry out.

If you fertilize the soil in wet soil,
- it will wash away with the water,
- excess nitrogen in wet soil can cause root rot or fungal problems.
- Result: Waste of fertilizer + no benefit to the plants.
When to Give Fertilizer in Monsoon

Heavy rainfall wash away the nutrients along with the potting soil.
- Wait for the rain to stop for 1-2 days and soil becomes slightly dry.
Always remember: Do not fertilize all the plants unnecessarily, fertilize only those plants which are in flowering, fruiting or in a growing stage.
- You can fertilize the plants once or twice a month as per the need.
