All the flowers used for the worship of the Lord Venkataeswara Swamy are not given to anyone as ‘Prasadam’. They are deposited in this well of late, flowers are being used in huge quantities for the decoration of the Lord Balaji and his consorts. This flower well is situated at the exit of the garbha stala. After having the dharshan of Lord Venkateshwara swamy you can see this flower well on the way out.
As the ‘flower well is unable to hold this huge quantity of used flowers, the tirumala tirupati devastanam staffs has shifted to other place on the seven hills where humans will not go.
