Tim,

I suppose that could have happened, I am familiar with root tropism in
pots. They were planted in 2015 when we had plenty of rain, we are in a
temperate rain forrest according to the Nat. Weather Serv. Last summer we
had an unpresedented drought, I have been here over 20 years and never seen
it so dry. We usually get up to 60 inches of rain and we were about 35
inches short, I think that we only got about 25" all season.

To many people in other places that seems like a lot but when you are used
to a lot of rain, the plants are used to it and have adapted to it. However
we can't grow good geraniums because of to much moisture an humidity and
other dry climate plants.

I am going to bareroot some of them and plant them in some very loose soil
and see what happens, our soil is predomantly clay here. I will make sure
they don't get dried out. If I do it now they will have to have some
protection as we can get frost any time in April.

Will see what happens, I would really like to have them in my garden.

I believe the potting soil drying is not due to drying per se, but rather a
root tropism designed to deal with rocks.
Since all potting soils are very loose, many native soils can appear to be
rocks in comparison (especially clays). The root growth then tries to
avoid
the rock and ends up circling the hole without breaking into the native
soil. In pots, this is called 'spin' because the roots circle the
perimeter
of the pot. Out in the ground, this will not show as a problem in rainy
weather but after a couple of weeks without rain, the roots absorb all the
moisture in the potting soil and then the plant dehydrates and dies.

I got your recent message, maybe it was the potting soil drying, I'll try

that. I

plant most other things with potting soil and have not had a problem as

far as

I know.
Should I wait until they are fully up or bareroot them now and plant

them.

They are up about 1 - 1 1/2 inches right now but in a cold frame. Perhaps

I

should bareroot them, plant them and protect them from frost if we get

it.

That seems like the better approach.
