Aloha, Ti plants grow in full sun with no problem. If your plant has been a house plant for awhile, though, it might need "hardening off" before it goes out to full time sun. Put it in a shady spot outside and move it more and more into the sun . Eventually it will be out in the full sun. They grow faster and fuller with partial shade and loads of water although the soil should drain. I can't remember any ti plants growing in water like taro, but they do grow faster with more water. Wind doesn't bother them too much, but if the wind is strong they might get shredded leaves. A hui hou, Cathy

Here's some info from Floridata.com: https://floridata.com/plant/31 States that flouride in the water can cause leaves to brown. Are you watering from overhead or at the base of plants?

if dead.. things rot .. and eventually it can be easily pulled out.. whats your hurry No "hurry", per se, other than the aesthetics of it this or next year. I liked the look of the mandevilla with it, but I don't have any this year so I probably won't do that again until next year. I was also concerned that the roots of the mandevilla could be wrapped around the roots of the cordyline, and its rotting could lead to killing the other. If that's not an issue, though, then I'll just cut the old stalk down and let it do its thing :-)

im not sure your presumption is correct ... why would two shoots from the same root mass ... interfere with each other ... so what if one is taller than the other... face the shorter one towards the sun.. and let it block the back one until it catches up ... i suppose the place to start .. wouldl be to baqre root it.. and SEE if it can even be divided ... if not.. repot.. and put in shade until the roots start pumping... if you can get root with each piece... divide it.. and dont look back .. or cut one piece off.. and root it... and leave the other with the roots ... https://duckduckgo.com/?q=cordyline+propagation&t=ffcm&iar=videos&iax=videos&ia=videos and figure out how to store it in winter ... so many options.. so little time .... ken
