Many fruit trees are cultivated by grafting the body of a sapling onto a rootstock. Indeed, if the sapling dies, the mature tree gains nutrients from the decaying sapling. An example of competition is a sapling growing under the shadow of a mature tree. Throughout the process, the mature tree is unaffected by the sapling. A new sapling has been planted nearby. Other impalement devices included bamboo whips and triggered sapling spikes. Soon, a sapling sprouted from the wet earth. The first sapling was planted in April 2013 at The Children's Museum of Indianapolis. A 10-year-old sapling grown in full sun will stand about tall. A 10-year-old sapling grown in optimal conditions will stand about tall. A 10-year-old sapling will stand about tall. They are fast growers and a 10-year-old sapling may stand about tall. Tannin produces negative effects on sapling growth. The second sapling survives at UBC.
