I'm new to Lilies. I've always loved how beautiful they are & their fragrance is a added plus. My birthday(Valentine's Day) I received2 lilies in a pot together. One plant had 4 blooms 3 of which that were already bloomed. The other plant has 4 blooms 2 are about to open. The 1st plant the leaves have started to fall off. Its green not brown so I'm puzzled why they have fallen off. There is only 4 leaves left. The 2 and plant has only had maybe 3 fall off. But 2 blooms that are about to open are turning brown at the bottom of the bloom. I'm clueless about lilies any help or advice would be great. Thank you!
