My oriental lilies are not blooming. Why? It seemed to be ready to bloom and then started a slight droop.

They may have thrips. These attack the base of the flower and cause it to fall off eventually. Here is more information on them:

It may also be related to a lack of water or a root issue. Increase the water a bit and if it does not improve, try checking the roots as well.

Q. how do I deal with plant pot pests

I transplanted some lilies from a planter to some pots. They appeared to cope with this very well, the buds opened and seemed to thrive, but then small red bugs began to appear. I removed them and treated the plants with a bug spray; unfortunately, this was not enough because the stalks of the plants have been stripped bare and some of the heads have dropped off. What I have noticed on my last inspection are small larva/bug-like pests munching away. Could you tell me what they are and how do I deal with them?

Not certain but it sounds like the lily leaf beetle may be to blame. Here is more information: https://www.gardeningknowhow.com/ornamental/bulbs/lily/lily-leaf-beetle.htm

Q. Lilies, African Daisies, Marigolds

I have some potted lilies that are outside. About a week ago, we received a lot of rain, which we really needed. But after the rain, there was no sun. We haven’t had sun for a week now. And the temperature has dropped. And looking at the forecast, we won’t have any sun for over another week. I have moved the plants so they won’t get anymore rain. My concern is the lack of sun. What should I do to make sure that the thrive through these sunless days to come?

Your lily plants will be fine is the sun doesn't shine for a while. They will still be getting ambient light that will keep them happy until the sun is out again. The rain should not hurt the plants unless they are in a container or soil that doesn't drain well.

Q. Caring for Oriental Lilies

I bought these lilies and it says they will grow 20″ tall. Should I plant them in a pot or in the ground? I also live in New Mexico where it is dry and windy. What do you recommend?

You can grow them in sun to part shade with fertile, well-draining soil. Bulbs are normally quite resilient as far as growing conditions go and are suitable for both the garden and container envionments, so this choice is really up to you. However, the plant will require additional water in a pot, especially if your region is dry and windy. Speaking of this, other plants that respond well to these conditions include xeriscape plants. The following articles should help: https://www.gardeningknowhow.com/special/xeriscape/drought-tolerant-flowers.htm, https://www.gardeningknowhow.com/special/spaces/wind-resistant-plants-for-your-windy-garden.htm

Q. Possible Cutworm

I found my Oriental lilies with the top 6 inches cut off and lying on the ground. I have 2 questions: is this a cutworm’s work, because I thought they cut off at ground level, and why is it cut off if the pest doesn’t eat it?

It would not be cutworm. It was likely a rodent of some kind that was startled before it could finish the plant's flower buds. This article may be helpful: https://www.gardeningknowhow.com/plant-problems/pests/animals/garden-mouse-control.htm

Q. growing orienpet lilies in zone 9

Can they stay in the ground during the winter, and do they need cold to bloom? What to do?

You on the outside edge of the growing zone of 4-8 for Orienpet Lililies.
Since they are a perennial they do need to stay in the ground year-round.
They do need a chill down of at least 8 weeks during dormancy.
There are some reports of some success in zone 9.

Look for bulb varieties that list zones 9. Purchase from a reputable source and review their guarantee.

Q. Black Spots on foliage of Lilium orientalis

I live in Seattle, recently my oriental lily foliage started to develop some black spotting. I fertilize it about once a week with 9-18-9 water soluble liquid plant food. The pH is about 6.5. Any idea what it could be?

I suspect a fungal disease, but which one I'm not sure; there are multiple possibilities.
What can you do? Sanitation, prune out and dispose of infected leaves, avoid overhead watering that can spread the spores, address soil fertility and water management to keep the plants as healthy as possible to resist disease.
A systemic fungicide from your garden center can be considered.

The following link has the best description of the various possibilities that I could find.
