Mechanical shaping: one is to clamp the inclined blade with the adjacent upright blade with a small clamp (note that the clamped part should be padded with soft paper to prevent the blade from being clamped), and the inclined blade can basically return to the upright position after a period of time. The other is to bend two bamboo strips with the same length and thickness into an arch shape, and then insert them into the inner edge of the flowerpot along both sides of the fan-shaped leaves of Clivia to form a clamping force. When the strength is insufficient, a thin rope can be tied between two bamboo sticks.

Light shaping: cut the opaque cigarette tin foil (other opaque thick paper can be used) into the same length and width as the blade, then fold it in half longitudinally from the middle to cover half of the blade tilted by sunlight, and then stick the tin foil on both sides of the blade with transparent tape. After 10 to 15 days, the crooked leaves were corrected. This method will not damage the blades, and it is simple and practical.

It should be noted that when the center line of the corrected blade is basically consistent with other blades, the wrapped tin foil should be removed in time, otherwise it will be overcorrected.
