Philodendron heterocraspedon

Upon arrival the roots were completely black and dry. I informed Ecuagenera right away. A day later the newest leaf became completely limp and lifeless and the new growth point was brown and unhealthy. I again reached out to them and their only suggestion was to put it in Sphagnum Moss. Two days later the leafs have developed this silver blotches all over the leafs and the plant is most definitely not going to make it. Pretty disappointing... This was a wishlist plant. I am going to have to propagate it in order to get anything from it if that's even possible...

Not sure what I did wrong but this plant didn't even make it a full week!

Plant received was easily >30cm leaves. I am very pleased with the plant. I was able to acclimatize the plant within a few weeks and a sprout was produced soon after.
