HOIGON 10PCS 12 Inches Plastic Oval Bonsai Training Pots, Black Large Oval Planter Pot with Drainage Hole Review (2026)

Who this set of pots is for

This is a bulk buy, not a single decorative pot. HOIGON ships ten oval training pots in one order, each measuring roughly 12 by 9.4 by 3.3 inches, so it suits a grower moving several trees out of nursery containers at the same time rather than someone potting up one gift tree. The oval shape is the standard training profile bonsai people reach for because it spreads roots wide and shallow, which is exactly the growth pattern a tree needs before it can go into a display pot. Anyone developing raw stock, growing out seedlings, or maintaining a small collection of pre-bonsai will get more use from a set like this than from a single fired ceramic pot, since training pots get swapped every year or two as roots fill in and get pruned back.

What the pots are made of and how they drain

Each pot is molded plastic, described by the maker as sturdy and resistant to fading, with raised feet on the underside that lift the pot off the bench for airflow and to stop the base from sitting in standing water. The listing notes six drainage holes per pot, which is enough for the loose, fast draining mixes bonsai growers typically use rather than dense potting soil. Plastic training pots like this are meant to be functional, not attractive, and the black color and oval shape are chosen because they roughly mimic the shape of a finished bonsai pot, training the root pad into a shallow, radial spread while the tree is still being developed rather than displayed.

Using and caring for the pots

Because there are no built in trays, indoor growers will want separate saucers underneath to catch runoff, and anyone repotting a lot of trees at once should have wire or mesh on hand to cover the drainage holes so soil does not wash out. Being plastic, the pots do not need the same frost precautions that unglazed ceramic pots do, but black plastic left in full summer sun does absorb noticeably more heat than a lighter color, which can warm the root zone on hot afternoons. Growers in warm climates may want to set these in part shade during the hottest stretch of summer, or group them together so the outer pots shield the ones in the middle.

Trade-offs against other training pot sets

Against GROWNEER's 9 inch three pack, this set trades matching humidity trays and a repotting mat for sheer volume, ten pots instead of three, which matters more once a collection grows past a handful of trees. Against HAKZEON's 12 pack in the same 12 inch oval size, the two are close in spirit, both are unadorned black plastic ovals with drainage holes and no trays, so the choice mostly comes down to whether ten or twelve pots better matches the number of trees being repotted. Neither rival includes a tray or mesh either, so none of these training pot sets solve the runoff or mesh problem on their own.

Verdict and who should look elsewhere

For a grower with several trees in nursery pots or garden centers ready to move into proper root training, this set is an efficient way to buy in bulk without paying for decoration nobody sees under a bench. It earns our score of 8.4 out of 10 mainly on fit for the job and value, with build quality marked down only because it is unadorned utility plastic. Anyone who wants a single attractive pot for a finished tree, or who specifically wants trays and a mat included in the box, should look at GROWNEER's smaller set instead, or a glazed ceramic pot once the tree is ready for display.
