2. Vitality of the tree stump. ① Scrape the rough outer bark of the trunk; if the inner layer is greenish and fine water droplets seep out, it is a fresh stump; ② Gently twist a branch; if it is flexible and does not break easily, or if the broken cross-section feels moist and the cambium is light green, it is a new stump; ③ Scrape the outer skin of a fine root; if the inner layer is white or flesh-red, fine water droplets seep out, the root system is supple, and the tips of the fibrous roots are still milky white, it is a stump that was dug up not long ago; ④ For evergreen stumps, those whose leaves remain evergreen and green, and have a glossy sheen, are the best.

3. Appearance of the tree stump. The leaves should be fine yet thick and glossy; the lateral roots should be thick and sturdy, positioned appropriately with smooth lines, and with many fine roots attached; the form should be unusual, the trunk robust and imposing, upright, or gnarled and full of variety; the branches should be distributed in an orderly way and full of dynamic movement, so that after selection and removal they can form natural crown pads.

The selected stump only needs to possess 2 to 3 of the above 5 qualities to be cultivated as a bonsai.
