If you have a garden outside your house or a piece of land adjacent to your house or space on the rooftop for some flower pots or even some space in balcony to keep some flower pots, then you can pursue your hobby of gardening. First thing in gardening is to remove the stones and boulders from the soil and make it smooth. Generally people either go for vegetable planting or flower planting or a mix of both depending upon the location of the land or flower pots.
During monsoon there is enough humidity in the surrounding and water is available for plants and in such a season there are various big sized as well as small sized vegetables which can be easily grown. Some of the common vegetables which are grown during this time of year are Lauki (Bottle Gourd), Tomato, Karela (Bitter Gourd), Carrot, Tinda (Indian Squash), Parwal (Pointed Gourd), Sem Phali, Tubers, Cauliflower, Kantola (Teasel Gourd), Radish, Cucumber, Beans, Bhindi (Okra) etc.
If your interest is in flowers then some of the flowers which can be planted during monsoon are Balsam, Marigold, Cosmos, Sunflower, Zinnia, Cleome, Salvia, Portulaca, Ageratum, Cocks comb etc. These flowers have beautiful colours and can give the place an ambience of superior kind.
Whether it is flowers or vegetables, it require some fertilisers for the good growth of plants. There are many types of fertilisers available in market specifically for these plants and can be used accordingly. NPK (Nitrogen, Phosphorous and Potassium) fertilisers are very common and are used by many garden hobbyists. NPK fertilisers come in various ratios but 5-5-5 NPK would suffice for your purpose and about 1 Kg of this is sufficient for 100 sq. ft. of garden. If you are using organic manure then the rule of thumb is to use about 10 kg of it for a 100 sq. ft. of garden. It has to be evenly applied to the soil. If you are composting yourself then you can also use that in place of the organic manure.
