PROBLEM TO BE SOLVED: To provide a free-size grafted tree holder that can save the labor for the recovery of the holder, because the holder is biodegradable and does not need the labor for recovery, even when it is allowed to stand after the plant takes root. SOLUTION: A biodegradable rectangular card 1 is projected from one end in a tongue piece 2 into a band, the top end 2a of the tongue piece 2 is curved on the card body side and turned up to the card body side, further passed through the slit 3 formed on one end side of the card to form a circular supporter 4 and the grafted part between the stock and the scion is supported by the circular supporter 4.
