Re: Is there an answer??

I have lost indoor poinsettias too. I don't understand their needs. I
 had one outdoors in Caracus, Venezuela, and it was a bush about 6' wide by 8' tall. I hardly touched it and it loved the tropical climate.

When I lived in Chico CA, the previous owner planted 4 dogwoods, which never grew an inch while i lived there (4 years). They were supposedly 7 years old. Curious,  I dug down, and I found giant roots circling the tree as if still in a container.

I have a really good luck with planting trees following the guidelines of University of California Davis which we have been taught as Master Gardeners. This is to pull the root out of the pot as suggested earlier. I always do this in a nursery Nursery people  that complain do not receive my business. I make sure there are not circling roots strangling the plant/tree, and no J roots.

Once I have combed the tree roots in preparation to plant,  I prune the roots that are brown (outside and inside) until I see nice white (brown on the outside and white inside).

All good advice and true, but how do you know who the spoilers are?  I got lucky and looked up poinsettia on the web before I moved it from its Christmas pot to a bigger pot on the patio.  The advice was "don't disturb the roots."  I didn't, and the plant thrived so well that the next year I needed to move it to a bigger pot.  At which point my brain broke down and I forgot all advice and spread the roots.  Dead poinsettia.  So - is there a rule of thumb for which roots to disturb, or is it individual research?

Pamela,
 
Many nurseries (not all, but a good bunch of them) don't take good care of the root system of the plants they grow. Very often, plants are set too deep in de pot and the rootball is not disturbed when repoted, leading to a concentric web of spiralized eventually girdling roots. Talking about Spanish Garden Centers (where I assume you purchase your plants), very often a plant that is not sold right away will remain in the same pot for many years until it is finally sold. So.... Always check the roots of your plants before planting! I buy plants from all over Europe and the USA, and now (after poor results with some plants) I always wash of all the soil from plants that have been pot grown and cut away all the girdling/potentially girdling roots that have already developed. Then, I plant them in the new soil (no soil from the original pot added) and at the right depth. I do this with trees and shrubs. With perennials, I only loose the rootball.
 
Checking the root system before planting is something not than common in Spain for the average gardener yet. Besides, many "gardeners" here have had no training as gardeners at all... so false myths keep on rolling around, unfortunately.

Subject: Is there an answer??

I have been given alot of conflicting advice regarding planting small trees and perennials from tubs over the past years and whether one should plant the root ball intact ('don't touch it'! I  have been told)  or tease out the roots gently.   My (part time) gardener here in the Costa Blanca (not Spanish I hasten to add) says that I must not disturb the root ball.   I ask this because I have had several plants die on me after 2 years ( Echium candicans, Leonotis leonoris as examples) and when I pulled up the plant the root ball was completely bound up, dried up and had not spread out.  Both of these plants had 'sister'  plants' planted at the same time and which are very successful.  I have a watering system on all plants until established.
 
The conflicting advice to 'fan out the roots'  when planting is very much of interest and I would be fascinated to hear opinions from the very experienced members of this group about this conundrum for me and would appreciate any other information that could be helpful.  
 
I am thinking of planting a Papaya ( Paw Paw) this Spring.
 
Best wishes
