My ti plant is in the exact same situation as yours and also came from home depot. Im just letting it do its own thing. Some of the leaves are getting a little brown, but Im just keeping them on until the next leaves come and accumulate to the sun. The weather hasnt been very sunny here for the past week which might be helping it accumulate better. Just keep it on the moist side and wait. Once summer comes it should be used to the sun and looking much happier.

Good luck!

Here in sunny Florida cordylines do best in partial shade. (Even the varieties that are bred for full sun) Full sun bleaches and burns them. Ti's especially burn in the sun from water spots. I might suggest moving plants to less sunny location. If you can't, try to water from the bottom.

Mine are not in full shade, but they only get indirect sun, I have 2 planted on the north side of the house. In the heat of summer, it's 105+ here, several leaves got burned at the edges. Now they're looking good again. I keep the soil kinda moist, not soggy, and mist them a few times a week. I fell in love with the Ti plants, along with Croton, when I went to Hawaii last year. Unfortunately, all my Crotons died, they couldn't take the winter cold in my area (Bakersfield), the Ti did fine in the cold months. I think they thrive in HI because not only of the warm temp, but HIGH humidity as well. So try misting the leaves.

I am in FL too and keep mine in morning sun, afternoon shade. It seems to bring out the best color in the ti's. If I keep it in too much sun the colors sort of blanch out even when they are aclimated.

This variety will not take the full sun, like other cordylines.
