2 questions re big shrubs & trees in containers
Q1.....When large trees and shrubs are sold in containers are they
containerised when small and potted on or are they field grown and containerised. Q2.....I have a problem with shrubs and trees (esp) that are grown in containers.. Surely the root systems are inferior to field grown specimens. I have had several such plants that have failed after apparently growing ok, on removing them the roots have been found to be self strangulated. May I have the groups thoughts on these questions please. Bell |

@news6.svr.pol.co.uk: Q1.....When large trees and shrubs are sold in containers are they containerised when small and potted on or are they field grown and containerised. Q2.....I have a problem with shrubs and trees (esp) that are grown in containers.. Surely the root systems are inferior to field grown specimens. I have had several such plants that have failed after apparently growing ok, on removing them the roots have been found to be self strangulated. Dunno about Q1 I am with you on Q2, particularly with larger specimens. Small containerised trees seem to be OK, but you regularly see trees where the height doesn't seem to relate to the size of the rootball at all, and I have had bad experiences with those (though not actual failures - were yours delicate or exotic varieties?) My parents planted some containerised apple trees when we moved house in 1982: those trees took years to get going, and are still not as good as ones planted more recently as young saplings. I don't think it's just down to the containers, either - it's down to packing them in too tight, or whatever it is they do to create that elongated effect. Trees I've grown from seed in containers myself are tough as boots, and properly tree-shaped - IE, branches all over, a bush that slowly gets taller - not a 'stretched lollipop' effect. Victoria |

2 questions re big shrubs & trees in containers
"Annabel" wrote in message ... Q1.....When large trees and shrubs are sold in containers are they containerised when small and potted on or are they field grown and containerised. container grown = what is say on the tin Containerised = field grown, lifted and potted Often but not always you can tell the difference as Container grown are self supporting with maybe a stake. Containerised large specimens often have timber support struts across the top of the container to stabilise the rootball. Some things eg holly will normally be container grown as they resent lifting. Q2.....I have a problem with shrubs and trees (esp) that are grown in containers.. Surely the root systems are inferior to field grown specimens. I have had several such plants that have failed after apparently growing ok, on removing them the roots have been found to be self strangulated. Horses for courses see comment re holly. pk |

I have had several such plants that have failed after apparently growing ok, on removing them the roots have been found to be self strangulated. You might want to treat your container trees and shrubs rather like large bonsai. One of the key elements to successful bonsai culture is periodic root pruning, which involves taking off about 1/4 of the roots annually. I've seen this explained as forcing the plant to constantly renew its roots, keeping them young and vigorous, with corresponding benefits to the above-ground growth. Of course there's a flip side to this: species which do not tolerate root disturbance won't do well under this kind of regimen. -- Rodger Whitlock Victoria, British Columbia, Canada |
