mine has grown about 2 foot in the past year, so if you’d like it to grow fast, the best things to do is provide the best living conditions for it- light, soil and water. if space is tight, you can cross light your singer and band (lighting positions at sides of stage area) using cheap lighting stands to get some height. or you can bring easy science to a group of kids! it’s important to reward yourself for a job week done. thank you for your interest in our 37th season!
