A round bag fills differently from a square one. There are no corners for compost to bridge over, so the mix settles evenly and the root ball comes out cylindrical, which suits nursery stock that gets lifted and moved on. This one is built from breathable felt fabric, with a side window for crops that finish below the surface and two handles anchored by serged, cross-stitched panels rather than a single line of thread. It runs at 50 gallon for trees, shrubs and long-season vegetables, and the bag folds flat when the season ends.
Nursery stock gets lifted, trucked and replanted, and a container that distorts the root ball on the way costs the grower a season. These bags are round for that reason: no corners to trap wet compost, and a root ball that comes out the shape the plant grew.
A round wall spreads the load evenly and lets compost settle without bridging across corners, so the mix stays uniform from top to bottom. The felt fabric breathes and passes surplus water, which keeps air reaching the roots and stops the sour, waterlogged pocket that forms at the base of a sealed pot. The callouts below mark the parts that carry the load and the opening a crop comes through.
Two handles are anchored with serged, cross-stitched panels instead of a single seam, so a full bag can be picked up by hand and set down without the stitching pulling out of the felt. Trees, shrubs and long-season vegetables spend the whole season in the same bag and are moved to the planting position in it, roots undisturbed. Round bags of the same diameter stack for storage. The same wall system runs through the air pruning pot range.

The handle anchors are the part that fails first on a grow bag, so they are stitched through the wall and reinforced with a cross-stitch pattern that spreads the pull across the felt instead of concentrating it on one line. The rim is turned and stitched so the bag holds its shape when it is dragged into place, and the side window flap folds back between pickings. A 50 gallon bag is heavy once it is filled, so it moves on a trolley or with two people. Seed trays and starter pots sit with the seedling and propagation range.
Please tell us the diameter and volume your programme runs, since the same wall is built across a range of round formats. Orders ship in bags, on pallets or in cartons, with 500 pieces to a carton, and the flat bag stores in a fraction of the space a stack of rigid pots takes. Samples let a buyer plant one before committing to a container load. The wider soft container range sits in the planting bag range. Container and growing media supply is covered at HortiDaily and FreshPlaza.
Why choose a round bag over a square one?
Nothing gets trapped in a corner, the compost settles evenly, and the root ball comes out cylindrical, which suits stock that is lifted and replanted.
How are the handles fixed?
They are stitched through the bag wall and cross-stitched across the anchor panel, so the load is spread over a wider area of felt.
How are bulk orders packed?
In bags, on pallets or in cartons, with 500 pieces to a carton, and mixed sizes combined in one load.
Tell us the diameters, volumes and quantities your programme needs, and we will come back with the packing plan, sample and lead time.
