Baby seedlings with second set of leaves go into this size

for a couple months.

Next they are bumped up to the tree pot on the left.

I will also tell you I will not push these to bloom the first year,

it isn't important to me to see them bloom.  What is important is 

the quality of the plant.

Tree pots also allow for them to be sunk into a half gallon

or gallon pot.  When we move them into the Brug house for

the winter months we take a large pot and sink several to 

house them together and keep them stripped of leaves.

When we do larger cuttings they are housed in our root

trainers.

Here you can see the pot in a pot method, where the first pot

has holes in the side so the roots can escape.  When the pot is 

totally root bound is when we move them up to the five gallon pots.

This is usually when the plant is 3-4 years old.

Here are the older Brugs in their permanent homes of the 5 gallon buckets

which are the easiest to move and store.  These also can be stacked if you run 

out of room in the area where they are stored, just space them right and stack.

Much easier to move for one person with a dolly, for those of you without

a helper.

We do the pot in a pot method for other plants too!!

This also helps with wind and blowing over of the smaller

pots here when we get high winds.

Here you can see the plants are in their Spring-Fall spot

and see they are starting to take off.  We keep them stripped

and what you see is the new growth.  We are also testing the use

of fabric softener and found less pests, just wrapped a piece around 

the pole in each pot where there is some new growth.  We tend to stake

the plants until they are at least 8 years old, after that they are on their own.

Hope this help give you an idea of what pots to use.  We have found Brugmansia

love to be root bound to preform at their bests.  Bigger pots are not always the best 

route to go.
