Digging potatoes out of a bag is the part growers and gardeners both dislike: the plant comes up with the crop, and anything left in the compost is found weeks later. This bag puts a window in the side wall instead. The flap rolls back, the tubers that have sized up come out by hand, and the plant carries on growing above. The wall is non-woven felt, which breathes and drains, so compost does not stay soaked and roots stay fibrous. Sizes run across the felt range and the bag folds flat between crops.
Potatoes are the crop that makes the case for a bag with a door in it. The tubers form low down, under the plant, and the only way to reach them in an ordinary pot is to tip it out. This bag opens instead.
The side window has a flap that rolls back and holds out of the way, so tubers that have sized up come out by hand while the plant carries on above. What makes that work is the wall: a non-woven felt that breathes and lets surplus water leave instead of holding it against the roots, so compost stays workable rather than sour and waterlogged. Roots meet air at the felt and stop, which is what produces a fibrous root ball instead of one coiled round the base.
The bag needs no ground: patios, balconies and hard standing all work, which is where most of these go. In a nursery they run in rows on a bench or a slab, and in both cases the crop comes out through the window a tuber at a time rather than all at once. Onions, spinach, tomatoes and salad crops run in the same wall. The wall system is shared across the air pruning pot range.
| Use | Potatoes, onions and root crops on patios and nursery rows |
| Material | Non-woven felt fabric |
| Form | Round |
| Window | Side window with a roll-back cover |
| Handles | 2 stitched handles |
| Colour | Black |
| Base | Flat stitched base |
| Packing | Bag, pallet or carton |
A bag full of wet compost is heavy, so the handles are stitched through the wall rather than run along a single seam, and the load spreads across the felt when the bag is picked up. The rim is turned and stitched so the bag holds its shape when it is dragged into position, and the flat base lets it stand on paving without tipping while it is filled. Larger formats move on a trolley, and the biggest sizes sit with the tree and nursery container range.
Tell us the diameters and volumes your programme works to, since the same wall is built across a range of round formats, and colours can be matched on programme orders. Orders ship in bags, on pallets or in cartons, and the flat bag stores in a fraction of the space a stack of rigid pots takes. The wider soft container range sits in the planting bag range. Container and growing media supply is covered at HortiDaily and FreshPlaza.
Do I have to empty the bag to harvest?
No. The side window rolls back so sized tubers come out by hand, and the plant keeps growing above while the rest of the crop finishes.
Will the felt soak and stay wet?
The felt breathes and passes surplus water through the wall, so compost drains rather than sitting waterlogged around the tubers.
How are bulk orders packed?
In bags, on pallets or in cartons, with mixed sizes combined in one load.
Tell us the diameters, colours and volumes your programme needs, and we will come back with the packing plan, sample and lead time.
