Trees sit in their containers for longer than anything else a nursery grows, through sun, frost and every lift between, so the material has to hold. These containers are built from HDPE with UV stabilisers, in wall grades that suit heavy root balls and big formats, up to 200 cm across. The studded face keeps root tips stopping at the air instead of circling, so lifted stock carries a fibrous root ball that survives the move to its final planting position. Diameters run 15 to 200 cm with base plates from 15 to 60 cm.
Trees spend longer in a container than anything else a nursery grows, through sun, frost and every lift between, so the material underneath the design has to hold. These containers are built from HDPE with UV stabilisers, in the wall grades that tree stock calls for.
HDPE carries the abuse: it takes knocks without splitting, holds its shape under a full root ball, and stays workable in the wall grades the studded face needs. UV stabilisers slow the way sunlight ages the surface, while the wall keeps doing its job at every opening, stopping root tips so the root ball comes away fibrous and dense instead of coiled. The specification chart sets out the wall and base dimensions a programme is working from.
Olive lines, specimen stock and field-grown trees stay in these containers long enough that the pot becomes part of the growing system rather than a stage on the way to one. Air moves through the studded wall on every side and the base plate drains, so roots keep working through long outdoor service; at lifting, the root ball comes out whole. The same wall system is shared across the air pruning pot range.

Orders leave in the shape a programme actually plants: small rounds palleted in bulk, larger formats stacked for freight, and sizes mixed in one load with base plates to match. The same containers stand through a working season in our own tree rows, and repeat orders arrive on the same wall, the same plate and the same handling. The largest tree formats carry up through the tree and nursery container range.
Black is standard, with white and matched colours on programme orders, so yards and sales areas stay readable. Orders ship naked in bulk or packed to the programme spec, and samples let a buyer hold a wall grade against the stock it is meant to carry. Flexible soft containers sit in the planting bag range.

Which wall grade suits tree stock?
Tree containers run on the heavier wall grades, and the range spans 0.6 to 1.5 mm with custom builds available on programme orders.
What do the UV stabilisers add?
They slow the effect sunlight has on the plastic, so containers standing in the open keep their surface and their strength through outdoor service.
How do bulk orders ship?
Naked in bulk or packed to the programme spec, with panels and plates stacked for freight and mixed sizes combined in one load.
