Hi there! Hyacinth stems will continue to grow, so stems should be staked to prevent falling over. It looks like it could stand to get some brighter light, but not direct sun. (I'm a Master Gardener in St. Charles MO)
i love it! Thank you, I'm gonna stick her outside tomorrow to see if she'll straighten up
I agree with Weedwacker, but I wanted to add that if your windows are the newer energy efficient type they are designed to block the suns rays. UVA, UVB, etc. The plant may be getting light, but not what it really needs, and can lean away from that type of window.
