My bay leaf has some yellow spotty leaves, and some leaves have turned brown and curled up. Is this a disease I need to treat?
Yes. Likely, this is rot from overly wet soils, unfortunately.
I would treat with a fungicide and remove any infected growth.

I have 2 lollipop bay tree around 140cm tall planted in a pot each that I have had for around 7 years. One is doing great the other looks dead. All the leaves turned brown. I cut into the stalk which was still green so I have cut the head with all the dead leaves off. I didn’t think it through as now I’m just left with the stalk. Will the leaves ever grow back?
It is possible. It sounds like an issue that needed to be corrected with feeding, though. That or a fungal infection. I am unable to say for certain without seeing the damage.

The tree was planted from a pot over 10 years into a well drained spot in the garden. Even new growth is being affected with this issue. The whole tree looks very grey and lacking the normal glossy green associated with a bay Tree. This is the first year that the tree has been displaying this symptom.
At first glance, it appears to resemble Downy mildew. Upon closer inspection, I see signs of spider mites. Together, this will cause the decline of your plant.

What is the best method to germinate Bay Leave Tree seeds? and when is the best time? I'm zone 11
In your area, you can plant these at just about any time! There are a few things that will help you to prepare, though.
Once you are ready to germinate your seeds, you will need to soak them. Soaking them in warm water for 24 hours prior to planting will help them break dormancy from the seed coat.
Next, it is good to be aware of the lengthy germination time. This can take a few weeks, or it can take half a year. Yep! This process can take up to six months, unfortunately.
Planting is straightforward. This article will help:

Can you please advise how I can red rid of white 'spots' on my bay tree. Each year I brush them off and was the tree with a hose, but they still return.... How do I get rid of them?
If the white spots are sticky, the plant could be experiencing a fungus or scale. Here's an article that will help: https://www.gardeningknowhow.com/edible/herbs/bay/bay-tree-diseases.htm
If the white spots are dry, it may simply be a harmless lichen. https://www.gardeningknowhow.com/ornamental/fungus-lichen/treatment-tree-lichen.htm

I bought a bay leaf plant last spring. It did well all summer and was brought inside for the winter. It has only grown straight up and looks strange with only one spike!
Is there any new growth at the top? If so, pinch it off, and then if another leaf tries to grow from the top, pinch it off, too. This will force the plant to bush out a bit. Here's an article I hope will help:

We have 2 very large bay trees they are now outgrowing the very large pots. We need to know if they can be transplanted in the ground
Bay laurel is hardy in zones 8 to 10. Even though that range goes down to 15 degrees F (-9 C), the tree is frost sensitive at about 20 degrees F or -7 C. So if your climate is that warm in the winter, you should be able to transplant the tree out in the garden. Be sure and mulch well come winter time.
