Penjing is the ancient art of growing miniature trees in tiny containers. Originally developed in China, penjing was the precursor to bonsai, which was adopted by the Japanese. The trees are kept small and proportionate through careful pruning, feeding, and spare watering. Branches are trained in the desired shape by the application of wire coils. Weathered trees in harsh climates serve as natural models for the often gnarled, bent, and overhanging miniature trees. How old is penjing? Discuss
