Last yr. lily tree was 6' tall, big stalk with many flowers. Same plant this year has shrunk to 4-5' tall with skinny trunk and has 3 buds. Why is so spindly?
This could be due to winter chilling, sunlight conditions, nutrients, watering issues, pests or disease.
Review the link below on care and make adjustments.

I have red tree lilies in flower planted in pots last year all flowered last year, this year all in red flower with side shoots come up in flower put they are white flowers, why?
Your lily may have mutated. Random mutations happen during cell division and replication, after exposure to radiation or because of weather extremes. Or it could have reverted to one of its parent's characteristics. If you don't like the white, you can prune it out.

fall will I be able to divide bulbs or do I have to wait till I see a second stem coming up from ground? thank you Hi do I have to wait till I see a separate stem coming up from tree lily bulb before i dig up to propagate?
You can't divide the main bulb. There may be some young bulbils around the main bulb but it doesn't sound like there are any mature bulbs or they would have sent up stems.
I would wait another year at least and see if you get more stems.
