Hi, I am confused if the word "blend" in this sentence should be used as "blends" or "blended" or "blending"? Thank you so much for your help!

[This road is flanked by lush and verdant trees. If you look up now, you would find the big ceiling previously blends with blue and white now adding more green in it. ]

Answer

Are you trying to say that when you go under the trees, the blue sky that previously blended with the white clouds is now also blending with the green of the trees?

Answer

Previously implies the past so blended seems best. The sentence needs correcting.
