Q.How to save this plant
Is there any way to save my plant?

Zone 600026, are you in Chennai India? If so please identify the plant if possible, because it may not be a species that we are familiar with and we may need to look it up. I lived in Tamil Nadu for two years, so I know the harsh hot climate. During the hot dry season you will need to pay particular attention to water management, and possibly need to water every day. Shading may be needed if not a plant that is tolerant of full sun there and 40C degree days. During monsoon season you may need to address draining of excessive and standing water if possible.
