Tree and berry nurseries run on rows, and a row is only as strong as the pot holding each root ball. This root control container is built for that setting. The studded wall holds root tips against open air through its drainage openings, so tips stop and the plant answers with new roots further back, and the wall stays stiff enough for lifting and re-potting through a season. Diameters run from 15 cm liner rounds to 200 cm tree containers on one system, in PE or PVC from 0.6 to 1.5 mm, black or custom colours, with bases from 15 to 60 cm.
Tree and berry nurseries grow in rows, and every row starts at the root ball. This root control container is the working end of that system: a studded air pruning pot made for open-ground production, sized from liner pots all the way up to full tree containers.
Every stud on the wall carries its own opening, and every opening is a place where a root tip meets air instead of more soil. A tip that reaches one stops there, and the plant answers by pushing fresh roots further back inside the root ball, the way a hedge thickens after pruning. That is what air pruning does in a row of stock: the lifted root ball comes out fibrous and dense instead of coiled into a ring. The same wall logic runs across the air pruning pot range, and the openings double as drainage, so pots on open ground or under drip lines never sit in standing water.
Field nurseries set pots out in lines and leave them there through a season, so a pot has to survive real handling: lifting, moving down the row, re-potting up a size. This one is molded to take it, with a studded body that keeps its shape all the way through. Sizes ladder up the way stock does, from small rounds for liners and berry plants, through the mid formats for shrubs and hedge lines, to the large containers that hold field-ready trees. A nursery can start a block on 20 cm rounds and move the same plants into 40 or 50 cm containers without changing pot system. Blueberry rows, tree lines and hedge stock all run on the same pot.

Base plates come in 15, 20, 30, 40, 50 and 60 cm and carry the root ball clear of wet surfaces, while the open grid lets water straight through. That matters most in the weeks after potting on, when new roots are working the base of the pot. As stock grows, the same pot travels with it until it is time to size up; the large formats at the top of the ladder are covered in the tree and nursery container range.
Black is the standard finish, with white and matched colours available for programme orders, so a nursery can keep rows readable at a distance. Packing is woven bag or carton, sizes combine freely in one load, and samples let a buyer stand a pot next to the row before committing a season. For soft containers in the same family, the planting bag range covers flexible growing. Trade coverage of production practice runs at HortiDaily and FreshPlaza.
Will these pots stand up to open-ground nursery use?
They are molded from PE or PVC with a 0.6-1.5 mm wall, and the studded body keeps its shape through lifting, row moves and re-potting.
What sizes suit a blueberry or tree programme?
Diameters run 15-200 cm with base plates from 15 to 60 cm, so one system covers liner rounds up to large tree containers, and custom sizes are accepted.
Can colours and sizes be mixed in one order?
Yes. Black is standard, white and custom colours run on programme orders, and mixed-size loads ship with samples available.
